How to Tune a Sailboat Mast

Here are some general guidelines for tuning your mast’s standing rigging . please see our blog on how to properly adjust a turnbuckle before you begin. as always we recommend seeking the advice of a professional rigger for more specific tips and tricks regarding tuning your boat’s rigging..

Your boat must be in the water. Begin by just slacking off all of the side shrouds as evenly as possible, so that all stays can be adjusted by hand. Once loose, try and adjust all turnbuckles so that they are pretty much equally open (or closed) from port to starboard respectfully. Also go ahead and line up the cotter pin holes (if present) in the studs so that they are in a pin-able position. Now is also the time to balance out the threads, between the upper and lower studs of the turnbuckle, IF they are not even. Do this by unpinning the turnbuckle from the chainplate – BE CAREFUL HERE – to ensure the mast is secure before unpinning any one stay. Lastly, loosen all halyards or anything that may pull the mast to port, starboard, forward or aft.

1. Check by sighting up the backside of the mast to see how straight your spar is side to side. You can take a masthead halyard from side to side to ensure that the masthead is on center. Do this by placing a wrap of tape 3′ up from the upper chainplate pin hole on each upper shroud. Cleat the halyard and pull it to the tape mark on one side, mark the halyard where it intersects the tape on the shroud. Now do this to the other side, the mark on the halyard should also intersect the tape similarly. Please note: when the mast is equipped with port and starboard sheaves, instead of just one center-line sheave, it will appear slightly off to one side. Just keep this in mind……

2. Using the upper shrouds as controls, center the masthead as much as possible using hand tension only. Some masts are just crooked. If yours is(are) crooked, it will reveal itself when you loosen all of the stays and halyards initially and sight up the mast. Although you should use hand tension only, you can use a wrench to hold the standing portion (the stay portion) of the turnbuckle. If for some reason the shroud is totally slack and you still can’t turn the turnbuckle by hand then the turnbuckle may need to be serviced, inspected, and maybe replaced.

3. Tune the mast from the top shroud on-down, making sure the mast is in column. Remember: as you tension one shroud by adjusting the turnbuckle, to loosen the opposing shroud the same amount.

4. Once the mast is fairly straight from side to side, tighten the shrouds all evenly using tools for tensioning. Typically, for proper tension, the shrouds should be tightened using these guidelines; uppers are the tightest, and then fwd. lowers, then the aft lowers and intermediates should be hand tight plus just a turn or two. ~ With an in-mast furler it is recommended to tension the aft lower a bit more to promote a straighter spar (fore and aft) for better furling.

5. Now you can tension the aft most backstay (s). If the backstay has an adjuster it should be set at a base setting (500-1000 lbs). If the backstay simply has a turnbuckle then it should be tightened well. After this has been done, in either situation (adjustable or static backstay), one should site up the mast from a-beam and notice that the masthead has a ‘slight’ aft bias. If there is no aft bias, too much, or the mast is inverted (leaning forward), then the forward most forestay (s) will most likely need to be adjusted to correct this. If a furler is present then seek the council of a professional rigger or refer to your furler’s manual for instructions on how to access the turnbuckle if there is one present.

6. Finally, sight up the mast one last time and make any necessary adjustments.

7. MAKE SURE ALL TURNBUCKLES AND PINS HAVE COTTER PINS AND ARE TAPED NEATLY TO PREVENT CHAFE!

I have a 1965 Alberg 30. On a starboard tack the boat has more weather helm than on a port tack. I have not been able to achieve a balanced helm on either tack. New full batten main, new 150 roller furl genoa.

Other than the boat being evenly ballasted from port to starboard, e.g. holding tanks, fuel tanks, below deck furnishings, and storage items, I would check the rig from side to side. A crooked mast or poor static tune can result in the boat sailing differently on both tacks. A good way to test this is either sighting up the mast at the dock to ensure that the mast is relatively straight side to side and in column. You can also see that when beating (aka hard on the wind), you have to make adjustment’s to the mainsail sheet tension (NOTE: the traveler will likely need to be adjusted to mirror the same setting as on the previous tack). If notice that with the traveler in the same position on each respective tack that the sail is bubbling or flogging more on one tack than on the other, it is likely necessary to re-tune the mast. This can be done at the dock by following the guidelines in the article once the everything has been appropriately loosened to tension.

Let us know if this helps.

Any Hints, tips for tuning a 1977 Whitby 27 sloop 1/4 ton rig?

Nothing special that I can think of. Just follow the guidelines in the article. From what I can gather there are only a single set of lowers correct? Are the spreaders aft swept at all or just straight out? If it is single lowers and no sweep to the spreaders you’ll need to set the rake using the forestay adjustment to set the rake and the backstay to control the forestay tension. If you are interested in optimizing sail tuning, like in racing situations: higher wind sailing conditions will desire more tension on the shrouds, a bit more tension on the lower than the upper, but only slightly; and in lighter winds loosen them up a bit, a tad looser on the lower than the upper.

Hope that helps, and good luck.

How do I tune /2 in rigging. Neither of the loos gaug s are large enough?

Thanks for the question. Yes, I think the Loos gauges only go up to 3/8″ wire. First let me say that a tension gauge is not a must for proper tuning, more for tension recording and also not exceeding max tension which is typically hard to achieve without additional fulcrums or wrench extensions. Having said that, if you know that you need one simply search google for cable tensioning gauges. There are a few others like this one https://www.checkline.com/product/136-3E , pricing is not easily apparent and may be excessive for your needs.

My recommendation is that if you have a good local rigger have them do a static dock-side tune and perhaps sail-tune in the boat’s ideal conditions. Perhaps they can provide a tutorial on their process for you to be able to make rigging adjustments over time.

Hope that helps.

Hi. Nice article. I have a Mirage 27 (the Bob Perry design). It’s a masthead rig with single spreaders and the shrouds on each side come to the same chainplate. I have been tuning so that tension on the lower and uppers is the same and trying to set them so that (as you say) the leeward shrouds are just slightly slack. But how do I induce mast rake? I have a split backstay with a 6:1 purchase on the adjuster; should the mast have rake even with the adjuster off? or do I just haul on it? or should the tension on the inners and outers be different?

HI Michael,

You will need to lengthen the headstay and shorten the backstay. This can be done a few ways either with turnbuckle adjustment or actually shortening and lengthening cables, sometimes you can add or remove toggles also.

Hope that helps!

Pingback: Buying a second-hand luxury yacht? Here’s what you need to look for - Phuketimes news

I recently purchased a 1988 Catalina S&S 38 and experienced my first launch this season, including stepping the mast and tuning the rig. As we prepared, we found that the Cap Shroud and Intermediate Shroud were clamped together at the four spreader ends. The folks at the yard had never seen that, and I certainly didn’t know why it was there … possibly to keep the spreader ends and shrouds consistent? Anyway, as I am learning how to tune my rig, it seems to me that these clamps would prevent me from tuning the cap shroud and intermediate separately and correctly Thoughts? Should I remove them and re-tune the rig?

So it is a double spreader rig I take it? The upper shroud wire should run freely through the first spreader, or the closest one to the deck, and be clamped at the top spreader. The intermediate shroud wire should be clamped at the lower spreader.

Before stepping, if this was done correctly, both upper spreader and lower spreader should be clamped equal distance from the mast attachment point, when looking at the mast from port and starboard.

In other words, you should measure the distance from where the upper shroud attaches to the mast to the end of the upper spreader and it should be the same distance on the other side, port to starboard. Then the same goes for the intermediate shroud and the lower spreader. The upper shroud should run freely through the lower spreader although it is covered by the clamp, but not actually clamped at the lower spreader, j ust the top one.

If all 4 spreaders are clamped equally port to starboard. You should be good to tune from there. The spreaders should show a slight up angle, to be specific slightly more up at the upper spreader than at the lower, but all of them should be just ever so slightly pointing up. You even want to think about clamping them slightly higher than that before tensioning, as this will pull them down and into their preferred angle, just slightly up. Specific angles are really only determined on the spar builders drawing and vary for manufacturer to manufacturer. Generally it is pretty clear where they want to sit. With the shrouds loose if you find that angle that appears to be the right one, and push them up slightly from there then clamp. This will allow them to be pulled down slightly once tensioned.

Kind of a tricky thing to explain in writing but hopefully it helps.

I have a Catalina 275 fractional rig with single swept back spreaders and an adjustable backstay. My questions are: how much rake, tension on cap and lower shrouds and on chain plate should cap shroud be forward and lower aft. I am racing and want the best performance. Thanks for any help. Bill

If the two shrouds are on the same plate, right next to each other, and the pin holes are the same diameter, and the plate is configured in a fore and aft configuration, I would choose the aft hole for the lower shroud and the forward one for the upper shroud.

In terms of specific rake, you will need to look towards the maker of your sails and or the boat manufacturer. I discuss how to measure rake in the preceding comments.

“You can measure rake by hanging a small mushroom anchor from the main halyard, with the boat floating on its lines, if you wish”

For racing I would start off with a good static tune at the dock by following the points in the article. If you know it’s going to be light day, start off with light rig tension. Be sure to use either Velcro wrap style cotter pins or simply lash the upper and lower shroud turnbuckles together to secure them. This will give you access to removing the pins or lashing while sailing and adjusting the stays.

From there you will need to sail tune for that days specific conditions, your shrouds will tell you what needs to be tighter and looser. I have answered how to do this a few times already in the comments below, please take your time to peruse the comments section to see what sail tuning entails. Doing this will always ensure that the cable tensions are set up ideally for the conditions and the boat can be sailed at maximum potential.

“For racing, ideally once the static tune at the dock (the part we just talked about) is done, go out and sail tune. Do this by going hard on the wind and checking to see if the leeward shrouds are just starting to dance, this is ideal. If they are swaying about they are too loose for the current conditions. If the leeward shrouds are tight, they may be a touch to tight. Tension and loosen as needed; count what you did and to what shroud, then tack and do the same to the other side.

ALWAYS secure the turnbuckles when you are finished adjusting them.”

Just hit ‘Ctrl F’ and search the page for “sail tune” and “rake”

I am trying to tune a Hallberg Rassy HR36 masthead rig. The rig has two in-line spreaders. The cap shroud is 3/8 inch and terminates at the lower spreader. From the lower spreader, the cable transitions to a 5/16 inch cable passing over the upper spreader to the masthead. A second 9/32 inch cable runs from the lower spreader to the mast (just below the upper spreader). The Selden rigging suggests that the “upper shroud” be at 15 percent of the breaking strength of the cable. In this situation, is it 15 percent of the 3/8 inch lower portion? If so, how should the upper 5/16 inch and 9/32 inch cables be tensioned?

Thanks for your help.

Hi Bryant, good question. Once proper alignment and centering of the spar has happened (static tune), and you are perhaps a hair tighter than hand tight on all shrouds, you can begin to tension things to a percentage of breaking strength. Do this by using the cables at the deck and use their diameters to determine the tensioning amount.

The V1 (aka cap shroud) in your case is a 3/8″ cable which supports the two cables above ii, hence its large diameter. The 5/16 V2,D3 and the 9/32 D2 total 19/32. So if 15% of the 3/8 cable is achieved you will below that threshold for the cables aloft. Does that make any sense?

With that in mind there is a range of acceptable tension from light air to heavy air. 15% sounds like a good middle of the road tension. Generally you do not want to exceed 30%. Sail tuning in ideal conditions is generally the best way to determine the right tension, but 15% of breaking strength sounds like a good place to start.

Don’t forget your cotter pins and tape, especially aloft.

Hope that helps and thanks for the question.

T.R.C. Thanks you for the clarification regarding the V2,D3 and D2 load distribution. When I set the V1 tension to 15%, the tension on the V2,D3 was at 8 %. I then tensioned the forward shroud to 12 % and the aft shroud to 10 %. Then I tensioned the backstay to 14 %. After doing this, I measured the tension on the V1 to be 10 %. The only information I could find regarding tension on the D2 was that is did not have to be tensioned much. I tensioned it to 5%. The mast sights straight and I used a bossen seat on a halyard to measure to the lower part of the V1, which also indicated that the mast was straight. Did I overtension the fore and aft stays? Is the tension in the D2 too much or too little? Again, I appreciate your advice.

When you tighten the backstay it usually induces a bit of aft bend in the mast which will soften the upper shroud (V1) a bit. You can just take up on it again to get it back to 15% if you like. As I said there is a acceptable range for all of the stays, which you are well within. Everything else sounds like you did a pretty good job. Next up sail tune and see if there is excessive waggling on the leeward side, but in moderate breeze. The shrouds will begin to sway as the breeze builds, this could be a telltale to either reduce sail a bit or you can add some tension to the shrouds all the way around.

Should be all good as they say.

Cheers, ~T.R.C.

T.R.C., your advice has been invaluable. I took her out in 12-15 knots and was very happy with the sail luff and stiffness of the rig. Thanks for you help!😁⚓️

Hi , can you provide any tuning guides for a Swan 38 Tall mast single spreader rig with baby stay, I am keen to set the rig up for new North sails and race her competitively. The mast is an exact Nautor factory replacement in 1998. She shall not have furling sails.

Hi Peter and thanks for the comment.

Unfortunately we do not have a guide for that boat. I would ask the sailmaker however to see what info he or she might have. Alternatively you can always start with a good static tune and then sail tune the boat as I describe in some of the comments below. This is the best way. I may use a Swan 45 Tuning guide as the template and then just fill in my own numbers over time. This is ideal, but infidelity start with asking the sailmaker you are working with, he should have some good info.

This may seem like a silly question, but it has me perplexed. How long should my cotter pins be? Long enough to ‘jam’ against the surrounding body, to prevent rotation? Otherwise, I don’t see how they’ll prevent my stays from loosening.

The length should be the minimum amount to just be able to bend the legs. Too long and they get caught up on things, too short and you can’t adequately bend the legs to keep the pin in place. The head of the pin is a actually providing the security.

Does that help?

Great article to get me started, thanks! I just have a few questions…

I originally owned a Tanzer 7.5. Her mast was rigid and simple to tune with a LOOS and an eyeball. I however now own a Mirage 33 (1982) and things are a bit more complex (but not too much). When I bought her the mast was already stepped and the owners said they replaced the forestay (inside the furler) 1 season ago. I went about the boat tuning the rig as best I could but I started second guessing the rake. I found noticeable rake in the mast with virtually no backstay tension on. So I think my forestay stretched (being “new”) and I need to bring it forward.

How do I measure how much rake (at rest on the tensioner) is enough? With my rig as is I felt worried that if I pulled down on the backstay tensioner I might buckle my mast by bending it too far. It seems to me it’s ALOT of downward pressure on the column when you pull down on her especially if the mast was already raked or maybe in my case leaned too far back to start? She has a babystay too, I wasn’t sure how far to tension that other than to assist adding bend\rake but since I had too much already I just lightly tightened it and hoped for the best!

Thanks for the question. With the backstay tensioner completely off, you should be able to adjust the static/ base tension of the backstay with a turnbuckle (s). Loosen the Baby Stay so that it is completely loose, sloppy, to take it out of the equation. Then mark furling line spool direction and remove the line. Next, open the furler up to gain access to the turnbuckle inside, if present. Remove all cotter pins or locking nuts to free the turnbuckles on the headstay and the backstay. You should then loosen things so that the headstay and the backstay can be adjusted by hand. Close the headstay turnbuckle and open the backstay turnbuckle to reduce rake, and vice versa if wanting to add rake.

You can measure rake by hanging a small mushroom anchor from the main halyard, with the boat floating on its lines, if you wish. Then once you achieve the desired mast rake go ahead and tension the forestay and backstay a few turns equally with tools; not too tight, but a good base light air setting, or as loose as you can imagine the headstay ever needing to be. Lastly, tension the baby stay a bit until it just starts to tug on the mast, helping induce bend. From here the backstay tensioner will do the rest: wind it on and it will tension the headstay and induce mast bend via the baby stay. You may have to take the boat sailing and adjust things as you find out how it performs at various degrees of rake and bend.

I hope that’s not too wordy, but helps explain it all a bit. Feel free to email or call with further questions.

Regards, ~T.R.C.

Can you provide some specific information regarding rig for 1980 C&C 32. Looking to purchase new main and want to get the most from it for Wednesday nights. Boat currently does not have a pony stay, it has been removed. Can replace that track/car. What should initial bend look like, keel step is fixed so assume I need to some chock aft of mast at deck? Have rod rigging but no Loos gauge for same, should I acquire one? Love this site, very helpful RayK

Thanks for the compliment. This may be less technical than you might expect. I would start with the basic guidelines given in the article to ensure a good base, static tune setting. A Loos gauge is good but not needed. If you focus on getting the spar straight, side to side, with a slight aft bias and then the tension is set so that it feels fairly tight. I know that sounds vague, but keep this in mind: if you are anticipating heavier wind make things a bit tighter, and loosen things up if less windy. The order of tension, in regards to the which shroud (upper vs intermediate vs lower) is important; more so than the amount of tension. Make sure nothing is so loose it is just flapping about.

The headstay should have some good slack to it with the backstay adjuster totally off. Adjust the backstay and headstay turnbuckles, with them in the slack position until the masthead is favoring a slight aft lean or rake, but only slight. From there, tension the backstay adjuster very tight and see what the headstay tension feels like, should be very tight.

PLEASE NOTE: if the backstay adjustment is totally bottomed out at this point, the backstay needs to be shortened a bit. Just pay attention to how this affects the rake. …

This part is where the pony stay or the baby stay will play a critical part, for mast bend. You may even find the pony stay to be good for mast pumping in light air and waves. Making this baby stay removable is a good idea, as well as, we’ve found that Dynema rope is the best choice here.

So… a centered mast head, side to side. A straight, in column mast from the top on down. A slight aft rake to start with…and as you begin to wind on the backstay and the baby stay you will add some rake but also a good bit more bend.

Take this set up for a few test sails and see how things act, in different conditions. After that you can make some adjustments here and there as needed: weather helm, shroud tension, mast rake, pre bend, etc…Moving chocks and using a Loos gauge.

ADDT’L TIP: Chocks and mast step position affect bend and rake properties. Want more rake? Chock mast aft in collar and move step forward. Want more bend? Chock mast forward in collar and move mast aft. As all things, there is more to it than that, but that’s the gist of the whole chocks and mast step thing…

“Sail Tuning” is a blog we are in the works of, but the punchline is that if hard on the breeze, and the leeward shrouds are excessively loose, and you are sure you aren’t over canvased…then go ahead and take turns on the leeward side until they just stop waggling, count what you’ve done, tack and mirror the turns on the other side.

Once the boat is set up for that specific condition, and you return to the dock, you should take your loose gauge and record these settings…creating a tension gauge setting for various conditions.

Hi, Thanks for your information. I have a Dehler 34. 1986… How much mast prebend and rake is recommended? The boat is new to me in March. Raced ok but I want to get a new main and want it to fit a well tuned mast. What do you think of a 2 degree rake and 4″ prebend at the speaders? Also, I have a Harken furler, How do you measure the forestay tension? Thanks, Duke

The answer, this boat is pretty sporty so it should show some rake. The spreaders are swept slightly aft so this will produce some natural bend just to tension the headstay.

Head-stays are always tough to measure with any sort of gauge, there are some class specific tricks for using a gauge in funky ways in order to get data, but they aren’t really reliable in my opinion. If you live in a typically windy area, go for bit more shroud tension, headstay tension and mast bend, and see how the boat feels. This will take some trial and error. If the forestay feels too stiff, slot too tight, loosen the uppers a bit, thus reducing bend and slackening the headstay.

Once the boat is sailing well in the ideal conditions, record that bend and those tensions. This is where I would leave things set, record it, and then just adjust shroud tension to affect bend and headstay in order to compliment different wind strengths and sea states. It takes quite a bit of back and forth, and documentation to get it right. One designers have already worked all of this out and then they share it for others…..very helpful. The rest of us will have to be the trailblazers for this type of information for other boat owners with the same (similar) boats to benefit.

Hope that helps, thanks for the kind words, and good luck. Once you figure things out post a link here for others with the same boat…..would be helpful.

Hello, Thanks for all of this great info. I just purchased a 37′ boat with a 3/4 fractional rig and a tapered mast. I was wondering if there were any special considerations when tuning the fractional rig? Currently the stays and shrouds are a little loose and can be wiggled (borderline flopping) by hand although the mast stands and is visually centered. (We are in SW Florida and the boat went through a direct hit by hurricane Irma like this and still stands tall!) Also is it advisable to increase shroud tension in small increments first on one side and then do the same on the opposing side? Thanks so much for any info

Hi Nathan. There are some thoughts, so fractional masts are usually fitted with aft swept shrouds and spreaders. If so, this means that the uppers also tension the headstay and create mast bend. The lowers then also act to reduce mast bend, so the tighter you make them you are actually reducing mast curve, thus powering the mainsail up. So be conscious of these two thoughts when tensioning the shrouds. The rest is fundamentally the same as the guide suggests. Loose or wiggling shrouds (excluding the scenario where we are talking about the leeward shrouds under sail), should be tightened. Doing things in increments is definitely a good idea.

Hope that helps. Thanks for the questions.

Thanks!! Now that you say that about the swept spreaders helping create mast bend it makes perfect sense. I had an ‘oh duh’ moment. I’ll probably err on the side of looser lower shrouds knowing if we need more power we can always tighten them up. Thank you again this helped immensely!

I want to buy a tension gage. Most familiar with Loos. But do I need Pt 1 or 2? (Pretty sure I don’t need 3 or Pro.) I have two rigs to tune: a 1972 Morgan 27 and a Catalina 22, I think 73 or thereabouts. The Morgan 27 is mine, fresh water for life, and 99.9% most likely factory wire. The Catalina 22 is a borrower in the Gulf, but pretty sure the owner has never tuned it. My problem is I can’t find the gage of wire for either standing rigging anywhere! Any help?

I think this one will do… https://sep.yimg.com/ca/I/yhst-70220623433298_2270_120385950 . The Morgan is likely 3/16″ wire and the Catalina is likely 5/32″, that’s an educated guess. Hope that helps.

I just purchased a 1980 C&C 40. I was told that I need to replace the rod rigging as it is “too old”. The mast is down and the rod rigging seems ok but I have not done any penetration testing. Does rod rigging need to be replaced due to age? Thanks Rigging Co.

Not replaced, but re-headed. This can mean that some stays need to be replaced as a whole, but not typically not the whole set. There are instances where you’ve almost replaced all of it anyways, so full replacement just makes sense. Other than those scenarios, full replacement is due after a certain mileage with rod…60,000 NM. Please keep in mind these standards are very general recommendations. It sounds like in your case, you should send in the rod, tangs, and chainplates for service and inspection. once we receive everything we will make a quote for the recommended services and/or replacement.

Hope that helps and give us an email for more info.

I have had a problem with securing the spreaders to the shrouds, resulting in the spreaders dropping. I am using stainless wire to seize them but still having a problem. Any tips on how to do this properly?

Seizing the wire onto spreaders with hinged spreaders is a bit of a trick of the trade that requires some practice. We use the X’s and O’s method. The end result should be something that looks like this… https://theriggingcompany.files.wordpress.com/2011/11/2012-06-07_14-26-09_899.jpg?w=900 . A trick to make the wire bite into the spreader end a bit more is to wedge a small piece of leather between the spreader and the wire before seizing. Also parceling and serving the wire where it intersects the spreader will help create more bite too. Lastly, and I don’t like this method but you can install a bull dog cable clamp beneath the spreader, nuts facing in, to keep it from dropping when slack.

I hope that helps a little. Thanks for commenting.

I am struggling to get enough rake into my mast. 33 foot Charger 33 keel stepped. Have loosened forestay and moved mast foot forward by about 10 mm. Should the chocks in the collar be adjusted? Runners and 2 spreaders, and check spreader. Spreaders do not have much aft angle. Move mast step more forward? Outers are tight with inners looser. Thoughts?

Hey Bernard,

Yeah, it sounds like chocks are the last thing. Maybe remove the chocks with the rigging slack and see if you can get the mast to sit where you like it with just hand tension. Then chock it where it wants to sit. It sounds like you are on the right track everywhere else, perhaps add a toggle into the headstay and shorten the backstay is next. Good luck and I hope that helps somewhat.

Hi, We have a Lagoon Catamaran with fractional rig, upper and lower shrouds, fore stay and upper and lower diamonds. No back stay. The mast has a degree of pre-bend. I do not plan to drop the mast.

I may have to do some work on the port side upper diamond. Is it as easy as just undoing the turnbuckle? Or do I need to loosen the starboard one at the same time. If it needs replacement should I also replace the starboard one even if in good condition?

As a further question, what happens if a diamond breaks, does it result in mast failure?

You would need to loosen the other counterpart to that stay for sure. It is just good practice, will keep the mast straight, and also make your life easier for removal install. Now, do you replace both? I don’t know. How old is the standing rigging? Why are you replacing the one? If it is not all due for replacement and you are just replacing due to damage, just do the one, but loosen both sides to do this.

Hope that helps and thanks for the visit.

Hello! I recently purchased a keel-stepped 1982 Goman Express 30 which came with an Alado Furler. I have been sailing it since May of this year. My question is this: Despite relocating mast wedges at the cabin roof to bias the lower mast aft about 2″, I still have a pronounced backward bend (10 degrees or so) just above the highest spreader. When sailing on jib alone, most wave action causes the mast to pump right at the bend point. I have a split backstay that is as un-tensioned as possible and the forestay only has another inch of adjustment left. There is no baby stay.

How can I get the bend out of the mast? How concerned should I be that the mast might break at that point?

Thanks in advance for your reply!

Eric Hassam – Delta Flyer

Thanks for taking the time to comment on our site. It sounds like you are on the right track. So one other adjustment that you have is the mast step position. This greatly affects mast bend on keel stepped masts. For a stronger bend and less rake, move the mast butt aft. For more rake and less bend (probably what you need to try), move the mast step forward a bit. If neither of these help, you may be off to have your headstay shortened and this means it is too long. This is likely not the case, but it is a possibility.

Keep in mind….A mast should have a slight aft rake bias along with a small amount of mast bend. This is quite normal. You can send us a picture if you’d like a second opinion on if it is over-bent. Having said all of that, even if you remove all of the mast bend, the mast may still pump. This is a design flaw in many spar designs that lots of end users have experienced. This can be remedied by redesigning the stay lay out. Is there a place for a staysail stay and/ or runner backstays? If so add them. Is there a place for a baby stay? If not, that may be a consideration.

Thanks again and I hope that helps.

Hi, I have a 48 foot yawl with a 7/8 fractional rig, is the tuning procedure the same as a masthead rig? I seem to have trouble getting aft rake and proper headstay tension. Also, is there a particular tension number the upper shrouds should have? many thanks in advance

Hi Bill, thanks for taking the time. 7/8 is very close and I would treat it like a masthead rig, especially if the none of the spreaders are aft swept. Tesnsion the headstay using the backstay(s). This should pull the top of the mast aft. If there are any other forward stays, i.e. stay sail stay, forward lowers, or anything else that could be holding the mast forward, go ahead and loosen those completely. You then may need to tighten the Tri-attic (the stay that connects the top of the mizzen and top of the main) if present. OR if the mizzen needs more rake too, then lossen all forward stays and pull it back using the available aft stays for this as well.

Hope this helps and please email us and send some pictures if you need more help.

I have a 1972 Morgan 27, which has both forward and after lower shrouds. I wish to remove the forward lowers so I can trim a 110% jib inside the stays. I see a lot of boats without forward lowers and think this will work OK, but wonder if I should increase the size of the aft lowers and beef up the chain plates. Any suggestions?

THANKS FOR YOUR INPUT. I AM GOING TO REMOVE THEM ANYWAY AND SEE WHAT HAPPENS. “HOLD MY BEER, WATCH THIS….” FAMOUS LAST WORDS.

Lol! Good luck. Call us if you need assistance.

I have rod rigging on my Beneteau 32s5

Any other guidance on tuning them vs wire rigging

Hi and thanks for commenting.

Just follow the guidelines in the write up. The over all goal is that the mast needs to be straight and in-column when looking at it from side to side.

Fore and aft, the mast should show a very slight lean aft. Depending on whether or not the spreaders are in-line or aft swept; you should also see some slight bend if there is any aft sweep to the spreaders just from the tension of the uppers.

A Rod stay tends to run a bit tighter than wire, so keep that in mind.

For racing, ideally once the static tune at the dock (the part we just talked about) is done, go out and sail tune. Do this by going hard on the wind and checking to see if the leeward shrouds are just starting to dance, this is ideal. If they are swaying about they are too loose for the current conditions. If the leeward shrouds are tight, they may be a touch to tight. Tension and loosen as needed; count what you did and to what shroud, then tack and do the same to the other side.

ALWAYS secure the turnbuckles when you are finished adjusting them.

The Running Rigging On A Sailboat Explained

The running rigging on a sailboat consists of all the lines used to hoist, lower, and control the sails and sailing equipment. These lines usually have different colors and patterns to easily identify their function and location on the vessel.

Looking at the spaghetti of lines with different colors and patterns might get your head spinning. But don’t worry, it is actually pretty simple. Each line on a sailboat has a function, and you’ll often find labels describing them in the cockpit and on the mast.

In this guide, I’ll walk you through the functions of every component of the running rigging. We’ll also look at the hardware we use to operate it and get up to speed on some of the terminology.

The difference between standing rigging and running rigging

Sometimes things can get confusing as some of our nautical terms are used for multiple items depending on the context. Let me clarify just briefly:

The rig or rigging on a sailboat is a common term for two parts, the standing , and the running rigging.

The standing rigging consists of wires supporting the mast on a sailboat and reinforcing the spars from the force of the sails when sailing. Check out my guide on standing rigging here!
The running rigging consists of the halyards, sheets, and lines we use to hoist, lower, operate and control the sails on a sailboat which we will explore in this guide.

The components of the running rigging

Knowing the running rigging is an essential part of sailing, whether you are sailing a cruising boat or crewing on a large yacht. Different types of sailing vessels have different amounts of running rigging.

For example, a sloop rig has fewer lines than a ketch, which has multiple masts and requires a separate halyard, outhaul, and sheet for its mizzen sail. Similarly, a cutter rig needs another halyard and extra sheets for its additional headsail.

You can dive deeper and read more about Sloop rigs, Ketch Rigs, Cutter rigs, and many others here .

Take a look at this sailboat rigging diagram:

Lines are a type of rope with a smooth surface that works well on winches found on sailboats. They come in various styles and sizes and have different stretch capabilities.

Dyneema and other synthetic fibers have ultra-high tensile strength and low stretch. These high-performance lines last a long time, and I highly recommend them as a cruiser using them for my halyards.

A halyard is a line used to raise and lower the sail. It runs from the head of the sail to the masthead through a block and continues down to the deck. Running the halyard back to the cockpit is common, but many prefer to leave it on the mast.

Fun fact: Old traditional sailboats sometimes used a stainless steel wire attached to the head of the sail instead of a line!

Jib, Genoa, and Staysail Halyards

The halyard for the headsail is run through a block in front of the masthead. If your boat has a staysail, it needs a separate halyard. These lines are primarily untouched on vessels with a furling system except when you pack the sail away or back up. Commonly referred to as the jib halyard.

Spinnaker Halyard

A spinnaker halyard is basically the same as the main halyard but used to hoist and lower the spinnaker, gennaker, or parasailor.

The spinnaker halyard is also excellent for climbing up the front of the mast, hoisting the dinghy on deck, lifting the outboard, and many other things.

A sheet is a line you use to control and trim a sail to the angle of the wind . The mainsheet controls the angle of the mainsail and is attached between the boom and the mainsheet traveler . The two headsail sheets are connected to the sail’s clew (lower aft corner) and run back to each side of the cockpit.

These are control lines used to adjust the angle and tension of the sail. It is also the line used to unfurl a headsail on a furling system. Depending on what sail you are referring to, this can be the Genoa sheet , the Jib sheet , the Gennaker sheet , etc.

The outhaul is a line attached to the clew of the mainsail and used to adjust the foot tension. It works runs from the mainsail clew to the end of the boom and back to the mast. In many cases, back to the cockpit. On a boat with in-mast furling , this is the line you use to pull the sail out of the mast.

Topping lift

The topping lift is a line attached to the boom’s end and runs through the masthead and down to the deck or cockpit. It lifts and holds the boom and functions well as a spare main halyard. Some types of sailboat rigging don’t use a topping lift for their boom but a boom vang instead. Others have both!

Topping lifts can also be used to lift other spars.

A downhaul is a line used to lower with and typically used to haul the mainsail down when reefing and lowering the spinnaker and whisker poles. The downhaul can also control the tack of an asymmetrical spinnaker, gennaker, or parasailor.

Tweaker and Barber Haul

A tweaker is a line, often elastic, attached to the sheet of a headsail and used to fine-tune the tension on the sheet.

Barber haul

A barber haul is a line attached to a headsail’s sheet to adjust the sheeting angle to the wind. It is often used to pull the clew further toward the center or outboard than the cars allow.

Boom Preventer

A boom preventer is a line attached to the boom’s end when sailing off the wind. Its function is to hold the spar in place and prevent it from swinging wildly.

If the boat were to get an accidental gybe, it could cause serious damage to the rigging or even harm people on board. It is important for the rigger to be cautious when setting up the boom preventer.

Running Backstay

Running backstays is similar to a normal backstay but uses a line instead of a hydraulic tensioner. Some rigs have additional check stays or runners as well.

Bonus tip: Reefing

The term reefing is used when reducing the effective sailing area exposed to the wind of a given sail. Headsails are usually reefed by partially furling them in, and they often have marks for what we refer to as 1st, 2nd, and 3rd reefs.

The mainsail is reefed similarly with an in-mast furling or in-boom furling system.

On a traditional mast, we use a system called slab reefing. The system has reefing lines running through the boom to reinforced points on the luff and leech, allowing you to pull the sail down to the boom and effectively reduce the sail area.

Having at least two reefing points in the mainsail is normal, but most cruising sailboats have 3. The 3rd is used for the heaviest conditions, giving you only a tiny bit of sail area exposed to the wind.

You want to reef your sails before the wind increases to a point where your boat gets overpowered.

It is essential to practice your reefing technique . You will find yourself in situations with rapidly increasing winds where you need to reduce your sails quickly.

Rule of thumb: If you think setting a reef might be a good idea, do it.

Shaking a reef is the term used when we sail with a reefed sail and want to increase the sail area back to full.

Hardware used for sail handling and the running rigging

Furling system.

Most sailboats have their headsail on a furling system. A furling system is a tube that runs along the forestay from the bottom furler drum to the masthead swivel.

This system allows you to roll the headsail around the forestay, making furling the sail in and out accessible. It is also convenient when reefing the sail when the wind picks up, as you can easily do this from the safety of the cockpit. These furling systems come in manual versions and electric versions.

In-mast furling

In-mast furling is a system that rolls the mainsail in and out of the mast. To unfurl the mainsail, we use the outhaul .

In-boom furling

In-boom furling is a system that rolls the mainsail in and out of the boom. This system has been costly and has mostly been seen on big yachts earlier. They are becoming more affordable and common on smaller boats, though. To unfurl this setup, we use the main halyard.

A Stack pack is also called a Lazy Bag or Lazy Pack. It is a bag with a zip attached to the boom where the mainsail is stored when unused. It protects the mainsail from UV rays from the sun and weather elements. It is a very nice and tidy way to store the mainsail and reefing lines if you don’t have in-mast or in-boom furling.

Lazy Jacks is a system of lines running from the stack pack to the mast. The Lazy Jacks guide the mainsail up and down from the Stack Pack and prevent it from falling down on the deck. It is also possible to rig Lazy Jacks without a Stack Pack.

A block is a pulley with a sheave wheel. Blocks are used to change the direction of a pull on a line or rope and give a mechanical advantage. They have many uses, especially onboard sailboats.

A winch is a metal drum that gives you a mechanical advantage to control and tighten lines. These can be operated by turning a rope around it and pulling manually or by a winch handle to get more force. Most modern winches are self-tailing, which means they lock the line on so you can winch the line without holding on to it. Some boats even have electrical winches operated by a button.

Mainsheet Traveler

The mainsheet traveler is a horizontal track that the mainsheet is attached to through a series of blocks. The traveler enables you to adjust and lock the boom at an angle and also plays a critical part in trimming the mainsail.

Most cruising sailboats have their traveler attached to the top of the coachroof in front of the spray hood. A racing boat typically has the traveler in the cockpit near the helm to give the helmsman better control over the mainsheet.

The cars are basically a pulley or block attached to a track on the port and starboard deck that your headsail sheets run through. Cars are used to control the angle of the sheet between the clew and the deck. The cars are handy when you trim the sail to set the right balance of tension between the foot and leech, depending on your point of sail.

The jammer is used to lock a line in place. Most sailboats use these for locking the halyards, mainsheet, outhaul, reef lines, traveler lines, boom vang lines, etc. You can pull or winch a line through a closed jammer, but it won’t run away if you let go of it unless you open the lock.

As I explained earlier, it is normal to have most or all of the lines led back to the cockpit, and they are usually run through a series of jammers.

The jammers are often labeled with the name of the line it locks, which makes it easier to remember which line goes where.

Spinnaker Pole

A spinnaker pole is a spar used to wing out a headsail when sailing off the wind, particularly the spinnaker. The spinnaker pole should have the same length as the distance between the mast and the forestay measured along the deck. We use a fore and aft guy and the pole’s topping lift to rig a pole correctly.

The rigging varies depending on the layout of the boat, but it usually looks like this:

One line runs from the bow to the end of the pole.
An aft line runs from near the stern to the end of the pole.
A topping lift is used to raise and lower the pole.

Whisker Pole

A whisker pole is similar to the spinnaker pole and is rigged similarly. It is typically built lighter and attached to a track on the mast. These can be found in fixed lengths or adjustable lengths. Ideally, the length should be the same as the foot of the headsail you intend to pole out.

Boom Vang/Rod Kicker

The Boom Vang has a few different names. Rod-kicker, kicking strap, or kicker. It is used to tension the boom downwards. When you are sailing downwind and have the boom far out, the mainsheet won’t pull the boom down as much as inboard, and you can then use the vang to adjust the twist and shape of the mainsail.

Mooring line

A mooring line is a traditional rope lead through a fairlead to the vessel’s cleat and a mooring buoy, key, or pontoon.

Final words

Congratulations! By now, you should have a much better understanding of how the running rig on a sailboat functions. We’ve covered the different lines, their purpose, and the hardware used to operate them. I hope you’ve enjoyed this guide and learned something new.

Now it’s time to take what you’ve learned and put it into practice by getting out on the water, setting sail, and getting hands-on experience with the lines.

Understanding your mast and rigging

by Simon Jollands | Boat Maintenance , Preparation , Yacht ownership

The rig of a sailing boat is put under huge stresses and strains so it is important for inspections of a yacht’s spars and rigging to be carried out at regular intervals.

All the elements of a sailing rig – the mast, spreaders, boom, kicker, stays and the fittings that hold everything together – are subjected to considerable forces when at sea.

Less obvious perhaps is that the process of cyclic loading, the cause of metal fatigue, continues unabated even when a boat is rocking gently on a sheltered mooring. The rig components continue to push and pull against each other, day in and day out. Added to the all stresses and strains imposed on the rig components are their susceptibility to different kinds of corrosion, caused in the case of aluminium masts both by exposure to the marine environment on the one hand and also by galvanic corrosion. This occurs when stainless steel or bronze fittings are fitted to aluminium masts and not adequately insulated from each other, which causes the aluminium to corrode. While wooden masts do not suffer from galvanic corrosion, they are susceptible to rot and de-lamination.

As with many other kinds of boat care, regular checks, preventative maintenance and the correct set up of mast and rigging are key to ensuring longevity and preventing failure. With sailing boat rigs in particular, the integrity of all their parts is vital. The mast and rigging is a lightweight structure designed to be rigid and strong, a bit like a house of cards – if one of the components fails then the whole house comes tumbling down. Even if one part becomes loose this can increase loads on other parts, causing them to fail.

While doing regular checks of your rig throughout the sailing season is good practice, so too is a more detailed inspection when the boat comes ashore and if needs be the mast can be taken down. Even if the rig remains unstepped ashore it still needs to be checked by a trained eye.

Understanding your rig

There are many kinds of mast and rig configurations for sailing boats and it is important for boat owners to fully understand the rig set up of their particular boat. This understanding will help them know what to look out for when doing their regular checks. Here are a few questions that owners should be able to answer:

Standing rigging

What are the main causes of rig failure?
When was the mast last unstepped? Once every two or three years is generally recommended.
When was the standing rigging last inspected? Annual inspections are usually recommended.
When was the standing rigging last replaced? Once every ten years or so is usually recommended for wire rigging and about fifteen years for rod rigging.
Where are the main stress points on your rig?
How do you check the rig alignment?

Running rigging

When was the running rigging last inspected?
When should it be replaced?
What maintenance needs to be done?

Causes of rig failure

While many sailors live in fear of rogue waves and capsize, most dismastings happen either because of equipment failure or operator error. Leaving aside operator error, the main reasons include the failure of chainplates, spreaders, turnbuckles and tangs caused by either metal fatigue, corrosion or a combination of the two.

Chainplate failure is one of the most common causes of dismasting. Chainplates are not easy to inspect as they are hidden from view beneath the deck. Corrosion happens out of sight where the metal cannot be inspected without the plates first being removed.

Other causes are the failure of terminal fittings, clevis pins, cotter pins and all the parts that hold a rig together.

Surprisingly perhaps, the mast and stays are rarely the components that break first and cause a dismasting.

Stresses and loads

The components of a rig are designed to withstand certain stress levels and loads caused by a boat under sail in varying conditions. The correct adjustment of the rig is important to maintain the rig’s strength and longevity for a number of reasons – not just the boat’s performance and ability to point to windward. These include:

If the rigging is slack problems can develop as it moves about, causing fatigue.
Rig components can become weakened by vibrations caused for example as sails flog in strong winds, or by shock loading caused for example by accidental gybes.
The misalignment of part of a rig can cause other parts to be overloaded resulting in metal fatigue and eventual failure.
Stress coupled with corrosion will accelerate the potential for rig failure.

Crevice corrosion

Some surface rust on stainless steel rigging is normal and usually polishes off very easily. While stainless steel does not rust in the way that regular steel does, it does suffer from crevice corrosion.

Crevice corrosion occurs because the stainless steel has been deprived of oxygen. As a result its protective oxide film breaks down, allowing chlorides to infiltrate and corrode the metal. This happens around joints and under fastener heads and where pieces of metal are in close contact. Chainplates often suffer from this type of corrosion where they pass through the deck and sea water has saturated the deck core.

Crevice corrosion also takes place where cyclic loading has caused stainless steel to develop hairline cracks on the metal’s surface. Sea water then gets into the cracks and the corrosion slowly takes hold.

Galvanic corrosion

Aluminium masts with stainless steel fittings are at risk from galvanic corrosion. Galvanic corrosion is the transfer of electrons from one metal (the anode) to another (the cathode). In this case the anode is the aluminium and the cathode is the stainless steel. Positively charged electrons flow from the the anode to the negatively charged cathode. Galvanic corrosion also requires an electrolyte, a liquid that enables the electron flow to take place. In this case salt water is the electrolyte and a very efficient one.

Note: All stainless steel fittings should be insulated from aluminium masts by washers or sealant

Sailboat Parts Explained: Illustrated Guide (with Diagrams)

When you first get into sailing, there are a lot of sailboat parts to learn. Scouting for a good guide to all the parts, I couldn't find any, so I wrote one myself.

Below, I'll go over each different sailboat part. And I mean each and every one of them. I'll walk you through them one by one, and explain each part's function. I've also made sure to add good illustrations and clear diagrams.

This article is a great reference for beginners and experienced sailors alike. It's a great starting point, but also a great reference manual. Let's kick off with a quick general overview of the different sailboat parts.

General Overview

The different segments

You can divide up a sailboat in four general segments. These segments are arbitrary (I made them up) but it will help us to understand the parts more quickly. Some are super straightforward and some have a bit more ninja names.

Something like that. You can see the different segments highlighted in this diagram below:

Diagram of the four main parts categories of a sailboat

The hull is what most people would consider 'the boat'. It's the part that provides buoyancy and carries everything else: sails, masts, rigging, and so on. Without the hull, there would be no boat. The hull can be divided into different parts: deck, keel, cabin, waterline, bilge, bow, stern, rudder, and many more.

I'll show you those specific parts later on. First, let's move on to the mast.

Sailboats Explained

The mast is the long, standing pole holding the sails. It is typically placed just off-center of a sailboat (a little bit to the front) and gives the sailboat its characteristic shape. The mast is crucial for any sailboat: without a mast, any sailboat would become just a regular boat.

I think this segment speaks mostly for itself. Most modern sailboats you see will have two sails up, but they can carry a variety of other specialty sails. And there are all kinds of sail plans out there, which determine the amount and shape of sails that are used.

The Rigging

This is probably the most complex category of all of them.

Rigging is the means with which the sails are attached to the mast. The rigging consists of all kinds of lines, cables, spars, and hardware. It's the segment with the most different parts.

The most important parts

If you learn anything from this article, here are the most important parts of any sailboat. You will find all of these parts in some shape or form on almost any sailboat.

Diagram of Parts of a sailboat - General overview

Okay, we now have a good starting point and a good basic understanding of the different sailboat parts. It's time for the good stuff. We're going to dive into each segment in detail.

Below, I'll go over them one by one, pointing out its different parts on a diagram, listing them with a brief explanation, and showing you examples as well.

After reading this article, you'll recognize every single sailboat part and know them by name. And if you forget one, you're free to look it up in this guide.

The stern is the back part of the hull. It's simply the nautical word for 'back'. The shape of the stern partially determines the stability and speed of the boat. With motorboats, the stern lies deep inside the water, and the hull is flatter aft. Aft also means back. This allows it to plane, increasing the hull speed. For sailboats, stability is much more important, so the hull is rounded throughout, increasing its buoyancy and hydrodynamic properties.

The transom is the backplate of the boat's hull. It's the most aft (rear) part of the boat.

Port is the left side of a sailboat.

Starboard is the right side of a sailboat

The bilges are the part where the bottom and the sides of the hull meet. On sailboats, these are typically very round, which helps with hydrodynamics. On powerboats, they tend to have an angle.

The waterline is the point where the boat's hull meets the water. Generally, boat owners paint the waterline and use antifouling paint below it, to protect it from marine growth.

The deck is the top part of the boat's hull. In a way, it's the cap of the boat, and it holds the deck hardware and rigging.

Displacement hulls are very round and smooth, which makes them very efficient and comfortable. But it also makes them very easy to capsize: think of a canoe, for example.

The keel is a large fin that offsets the tendency to capsize by providing counterbalance. Typically, the keel carries ballast in the tip, creating a counterweight to the wind's force on the sails.

The rudder is the horizontal plate at the back of the boat that is used to steer by setting a course and maintaining it. It is connected to the helm or tiller.

Tiller or Helm

The helm is simply the nautical term for the wheel.
The tiller is simply the nautical term for the steering stick.

The tiller or helm is attached to the rudder and is used to steer the boat. Most smaller sailboats (below 30') have a tiller, most larger sailboats use a helm. Large ocean-going vessels tend to have two helms.

The cockpit is the recessed part in the deck where the helmsman sits or stands. It tends to have some benches. It houses the outside navigation and systems interfaces, like the compass, chartplotter, and so on. It also houses the mainsheet traveler and winches for the jib. Most boats are set up so that the entire vessel can be operated from the cockpit (hence the name). More on those different parts later.

Most larger boats have some sort of roofed part, which is called the cabin. The cabin is used as a shelter, and on cruising sailboats you'll find the galley for cooking, a bed, bath room, and so on.

The mast is the pole on a sailboat that holds the sails. Sailboats can have one or multiple masts, depending on the mast configuration. Most sailboats have only one or two masts. Three masts or more is less common.

The boom is the horizontal pole on the mast, that holds the mainsail in place.

The sails seem simple, but actually consist of many moving parts. The parts I list below work for most modern sailboats - I mean 90% of them. However, there are all sorts of specialty sails that are not included here, to keep things concise.

The mainsail is the largest sail on the largest mast. Most sailboats use a sloop rigging (just one mast with one bermuda mainsail). In that case, the main is easy to recognize. With other rig types, it gets more difficult, since there can be multiple tall masts and large sails.

If you want to take a look at the different sail plans and rig types that are out there, I suggest reading my previous guide on how to recognize any sailboat here (opens in new tab).

Sail sides:

Leech - Leech is the name for the back side of the sail, running from the top to the bottom.
Luff - Luff is the name for the front side of the sail, running from the top to the bottom.
Foot - Foot is the name for the lower side of the sail, where it meets the boom.

Sail corners:

Clew - The clew is the lower aft (back) corner of the mainsail, where the leech is connected to the foot. The clew is attached to the boom.
Tack - The tack is the lower front corner of the mainsail
Head - The head is the top corner of the mainsail

Battens are horizontal sail reinforcers that flatten and stiffen the sail.

Telltales are small strings that show you whether your sail trim is correct. You'll find telltales on both your jib and mainsail.

The jib is the standard sized headsail on a Bermuda Sloop rig (which is the sail plan most modern sailboats use).

As I mentioned: there are all kinds, types, and shapes of sails. For an overview of the most common sail types, check out my Guide on Sail Types here (with photos).

The rigging is what is used to attach your sails and mast to your boat. Rigging, in other words, mostly consists of all kinds of lines. Lines are just another word for ropes. Come to think of it, sailors really find all kinds of ways to complicate the word rope ...

Two types of rigging

There are two types of rigging: running and standing rigging. The difference between the two is very simple.

The running rigging is the rigging on a sailboat that's used to operate the sails. For example, the halyard, which is used to lower and heave the mainsail.
The standing rigging is the rigging that is used to support the mast and sail plan.

Standing Rigging

Diagram of the Standing Riggin Parts of a sailboat

Here are the different parts that belong to the standing rigging:

Forestay or Headstay - Line or cable that supports the mast and is attached to the bow of the boat. This is often a steel cable.
Backstay - Line or cable that supports the mast and is attached to the stern of the boat. This is often a steel cable.
Sidestay or Shroud - Line or cable that supports the mast from the sides of the boat. Most sailboats use at least two sidestays (one on each side).
Spreader - The sidestays are spaced to steer clear from the mast using spreaders.

Running Rigging: different words for rope

Ropes play a big part in sailing, and especially in control over the sails. In sailboat jargon, we call ropes 'lines'. But there are some lines with a specific function that have a different name. I think this makes it easier to communicate with your crew: you don't have to define which line you mean. Instead, you simply shout 'mainsheet!'. Yeah, that works.

Running rigging consists of the lines, sheets, and hardware that are used to control, raise, lower, shape and manipulate the sails on a sailboat. Rigging varies for different rig types, but since most sailboats are use a sloop rig, nearly all sailboats use the following running rigging:

Diagram of the Running Rigging Parts of a sailboat

Halyards -'Halyard' is simply the nautical name for lines or ropes that are used to raise and lower the mainsail. The halyard is attached to the top of the mainsail sheet, or the gaffer, which is a top spar that attaches to the mainsail. You'll find halyards on both the mainsail and jib.
Sheets - 'Sheet' is simply the nautical term for lines or ropes that are used to set the angle of the sail.
Mainsheet - The line, or sheet, that is used to set the angle of the mainsail. The mainsheet is attached to the Mainsheet traveler. More on that under hardware.
Jib Sheet - The jib mostly comes with two sheets: one on each side of the mast. This prevents you from having to loosen your sheet, throwing it around the other side of the mast, and tightening it. The jib sheets are often controlled using winches (more on that under hardware).
Cleats are small on-deck hooks that can be used to tie down sheets and lines after trimming them.
Reefing lines - Lines that run through the mainsail, used to put a reef in the main.
The Boom Topping Lift is a line that is attached to the aft (back) end of the boom and runs to the top of the mast. It supports the boom whenever you take down the mainsail.
The Boom Vang is a line that places downward tension on the boom.

There are some more tensioning lines, but I'll leave them for now. I could probably do an entire guide on the different sheets on a sailboat. Who knows, perhaps I'll write it.

This is a new segment, that I didn't mention before. It's a bit of an odd duck, so I threw all sorts of stuff into this category. But they are just as important as all the other parts. Your hardware consists of cleats, winches, traveler and so on. If you don't know what all of this means, no worries: neither did I. Below, you'll find a complete overview of the different parts.

Deck Hardware

Just a brief mention of the different deck hardware parts:

Pulpits are fenced platforms on the sailboat's stern and bow, which is why they are called the bow pulpit and stern pulpit here. They typically have a solid steel framing for safety.
Stanchons are the standing poles supporting the lifeline , which combined for a sort of fencing around the sailboat's deck. On most sailboats, steel and steel cables are used for the stanchons and lifelines.

Mainsheet Traveler

The mainsheet traveler is a rail in the cockpit that is used to control the mainsheet. It helps to lock the mainsheet in place, fixing the mainsails angle to the wind.

If you're interested in learning more about how to use the mainsheet traveler, Matej has written a great list of tips for using your mainsheet traveler the right way . It's a good starting point for beginners.

Winches are mechanical or electronic spools that are used to easily trim lines and sheets. Most sailboats use winches to control the jib sheets. Modern large sailing yachts use electronic winches for nearly all lines. This makes it incredibly easy to trim your lines.

You'll find the compass typically in the cockpit. It's the most old-skool navigation tool out there, but I'm convinced it's also one of the most reliable. In any way, it definitely is the most solid backup navigator you can get for the money.

Want to learn how to use a compass quickly and reliably? It's easy. Just read my step-by-step beginner guide on How To Use a Compass (opens in new tab .

Chartplotter

Most sailboats nowadays use, besides a compass and a map, a chartplotter. Chartplotters are GPS devices that show a map and a course. It's very similar to your normal car navigation.

Outboard motor

Most sailboats have some sort of motor to help out when there's just the slightest breeze. These engines aren't very big or powerful, and most sailboats up to 32' use an outboard motor. You'll find these at the back of the boat.

Most sailboats carry 1 - 3 anchors: one bow anchor (the main one) and two stern anchors. The last two are optional and are mostly used by bluewater cruisers.

I hope this was helpful, and that you've gained a good understanding of the different parts involved in sailing. I wanted to write a good walk-through instead of overwhelming you with lists and lists of nautical terms. I hope I've succeeded. If so, I appreciate any comments and tips below.

I've tried to be as comprehensive as possible, without getting into the real nitty gritty. That would make for a gigantic article. However, if you feel I've left something out that really should be in here, please let me know in the comments below, so I can update the article.

I own a small 20 foot yacht called a Red witch made locally back in the 70s here in Western Australia i found your article great and enjoyed reading it i know it will be a great help for me in my future leaning to sail regards John.

David Gardner

İ think this is a good explanation of the difference between a ”rope” and a ”line”:

Rope is unemployed cordage. In other words, when it is in a coil and has not been assigned a job, it is just a rope.

On the other hand, when you prepare a rope for a specific task, it becomes employed and is a line. The line is labeled by the job it performs; for example, anchor line, dock line, fender line, etc.

Hey Mr. Buckles

I am taking on new crew to race with me on my Flying Scot (19ft dingy). I find your Sailboat Parts Explained to be clear and concise. I believe it will help my new crew learn the language that we use on the boat quickly without being overwhelmed.

PS: my grandparents were from Friesland and emigrated to America.

Thank you Shawn for the well written, clear and easy to digest introductory article. Just after reading this first article I feel excited and ready to set sails and go!! LOL!! Cheers! Daniel.

steve Balog

well done, chap

Great intro. However, the overview diagram misidentifies the cockpit location. The cockpit is located aft of the helm. Your diagram points to a location to the fore of the helm.

Thanks for quick refresher course. Having sailed in California for 20+ years I now live in Spain where I have to take a spanish exam for a sailboat license. Problem is, it’s only in spanish. So a lot to learn for an old guy like me.

Very comprehensive, thank you

Your article really brought all the pieces together for me today. I have been adventuring my first sailing voyage for 2 months from the Carolinas and am now in Eleuthera waiting on weather to make the Exumas!!! Great job and thanks

I don’t have a sailboat, neither do l plan to literally take to the waters. But for mental exercise, l have decided to take to sailing in my Bermuda sloop, learning what it takes to become a good sailor and run a tight ship, even if it’s just imaginary. Thank you for helping me on my journey to countless adventures and misadventures, just to keep it out of the doldrums! (I’m a 69 year old African American female who have rediscovered why l enjoyed reading The Adventures of Robert Louis Stevenson as well as his captivating description of sea, wind, sailboat,and sailor).

Great article and very good information source for a beginner like me. But I didn’t find out what I had hoped to, which is, what are all those noisy bits of kit on top of the mast? I know the one with the arrow is a weather vane, but the rest? Many thanks, Jay.

The main halyard is attached to the head of the mainsail, not the to the mainsheet. In the USA, we say gaff, not gaffer. The gaff often has its own halyard separate from the main halyard.

Other than that it’s a nice article with good diagrams.

Boat Clinic: Tuning the Masthead Rig

My father was a rarity: he really did not care at all how well the boats he sailed performed. Perhaps this was because, in his youth and young manhood, he had been both a tremendously aggressive and a wonderfully successful athlete and thus had wrung out his competitive needs.

Tuning the rig of a boat is one of the necessary -and pleasant -tasks which must be done to achieve good performance. In an untuned boat, the mast bends in odd ways, and this in turn causes the sails to set badly. By contrast, on a well tuned boat , the rig bends in a controlled fashion, allowing the sails to do their best. For this reason, an avid racer will be constantly fiddling with the tune of his boat, while for most of us a one time job during commissioning may suffice.

The first thing to realize is that for a mast to stand well, it should not be straight when in a static, no load situation. This was something I realized nearly thirty years ago when conventional advice was to tune rigs so that masts were indeed straight when static, and while that advice is still sometimes given, most of the sailing world has realized that a controlled static bend is needed.

The problem with a statically straight mast is that when loaded, it is too easy for the mast to invert, or bend backwards. This can happen when the boat is beating in a seaway or reaching with the spinnaker pole up. Most mast sections can accommodate a significant amount of forward bend without failure, but very little aft bend.

An afternoon spent on a poorly tuned boat a couple of seasons ago left me a nervous wreck. Each time the boat came off a wave the mast pumped and wriggled so much that you could see it changing shape from the tiller. The owner, happy man, was ignorant and oblivious to the danger of losing his rig.

In contrast, if you set up the rig so that it has “prebend”, that is, the center of the mast bends forward when in a static condition, the loaded mast will flex in the proper direction. What flex there is will then tend to flatten the main, rather than bagging it, and the boat should balance better, particularly in heavy air, when most boats start to develop helm problems.

The first job is to get the mast straight athwartships. Leave the lower shrouds hand slack during this procedure. Use the main halyard as a measurer. Take the shackle end of the halyard a measured distance aft of the bow along the gunwale, then have someone take up the slack while you hold the shackle firmly to that point. Cleat off the halyard.

Then take the end of the halyard to the same point on the other side of the boat. If the mast is straight athwartships, the halyard shackle will just kiss the same point on the gunwale on either side of the boat.

Because chainplates are rarely put on perfectly symmetrically on the two sides of the boat, it is best to go to the trouble to measure back from the stemhead on each side for your reference mark, rather than using the chainplates as the reference.

If the halyard doesn’t touch the same point on both sides of the boat, adjust the cap shrouds (upper shrouds) until the mast is straight. Be sure to loosen one side as you tighten the other, and sight up the mast to make sure that you haven’t put any sideways bend in. The sailtrack should be straight athwartships when you sight up the mast, unless it has been put on crooked.

It should be noted that if your deck is slightly crooked -a fairly common problem the mast may not be perfectly centered athwartships in the partners when it is vertical to the hull.

Don’t attempt to make the mast vertical by putting a level on the side of the mast. Almost no boat floats without a list to one side or the other, and your weight alone is enough to put a slight list on a surprisingly large boat.

At this point, on boats up to about 35’, the cap shroud turnbuckles should be hand tight. What’s hand tight? Just what it says: as tight as you can get a well-lubricated turnbuckle with your bare hands. Later, when testing under sail, you’ll find the leeward shrouds slopping around by a few inches; then, and only then, you can take the slack out of the leeward shrouds. If you have absolutely no slack in the leeward capshroud when the boat is going upwind in 1.2 knots of wind, the shrouds are probably too tight for most boats.

Next set the rake of the mast using the fore and back stays, again only hand tight. If you don’t know from experience what the proper rake should be, begin with a modest rake of no more than the fore and aft diameter of the mast. Use the main halyard as a plumb bob. Later you may wish to modify this rake. Utilize the facts that increasing mast rake and/or moving the mast aft increase weather helm,-while decreasing mast rake and/or moving the mast forward decrease weather helm.

Now that the mast is properly straight athwartships and properly raked, it’s time to start the controlled bends. These are accomplished with the forward lowers, babystay, backstay, and mast wedges. Whether your boat has double forward lowers or a single, centerline babystay doesn’t matter. Both systems accomplish the same end.

First, take up the babystay or double forwards until you’ve pulled a forward bend of 1/2” to 1” into the middle section of the mast. Again use the main halyard -this time pulled tight against the lower, aft edge of the mast -as a measuring reference. If using double lowers, make sure the mast remains straight athwartships.

Next crank up on the backstay until you’ve got a curve in the mast equal to 1/2 to 1 times the fore and aft dimensions of the mast. Finally, take up the aft lowers hand tight.

If your mast is stepped on the keel you need at this point to wedge it at the partners. Wooden wedges are easiest to make, but they can dent an aluminum mast if the shrouds are set so loosely that the mast leans to leeward significantly when sailing upwind. A fairly firm rubber wedge works better with looser rigs, and is probably the safest to use. Rubber wedges are usually harder to make, however.

Your boatyard or chandlery may sell special rubber for mast wedges. If not, try to buy something in the nature of thick inner tubing. In a real pinch, sections cut from old auto tires will do, but will have to be rasped to thickness. Don’t use a foam material; it’s too soft. You’ll need two wedges, one fore, one aft. The width of each should be about 35 % to 40% of the mast’s circumference. Thus, they’ll curve around both the front and sides of the mast. Since the rubber wedges must be under compression, their thickness should be slightly greater than the gap they need to fill. You may have to cement together several layers of thin rubber to achieve the proper thicknesses.

The first step in wedging is to trim the wedges so they do not push the mast out of column sideways. As noted earlier, many decks are slightly off center, so there may not be equal space on both sides of the mast, even when it is in the proper position.

When the wedges are properly trimmed for the sides of the partners, you are ready to insert the aft wedge. To support the prebend, put a line around the mast a foot or so above the partners, and run it forward to a fixed point -a snatch block on a mooring cleat or a bridle between the cleats -then aft to a cockpit winch. Now slip the aft wedge into place. Release the load on the line, and insert the forward wedge. A little soap on the wedge will ease a tight fit.

Now you’re ready for a sailing trial.

Choose a day when you can comfortably carry a genoa. About eight to 1 5 knots of wind will do for most boats.

Put the boat hard and full on the wind and check the mast. It should be retaining the same fore and aft curve you put in while tuning. If not, adjust the babystay or forward lower shrouds. Next check the athwartships shape of the mast. It should be straight. Any necessary adjustments should be carried out with the leeward shrouds, then the boat should be tacked to check the effect of the adjustments.

If the mast is straight athwartships, tack and hand tighten all the leeward shrouds by an equal number of turns. If the center of the mast bends to weather, tighten the capshrouds more than the lowers. If the center of the mast sags to leeward, tighten the lower shrouds more than the cap-shrouds.

You should also check the athwart-ships bend of the mast in varying wind strengths, adjusting the aft lowers until you’ve achieved the best compromise between a straight mast and one which falls off or hooks. A masthead which hooks to windward should be avoided.

When, after a few sailing trials, you’re satisfied, pin the turnbuckles, then tape everything that could catch a sail or sheet.

We’ve dealt with what might be called traditionally rigged masts, those with spreaders which sprout essentially at right angles to the mast. Nothing we’ve said, however, isn’t also true of fractional rigs with aft raked spreaders. The only difference is that on such a rig the cap shrouds, as they load up, work on the spreaders to increase forward mast bend, but that’s all to the better.

Tuning A Sailboat Rig

If your sailboat seems slower, follow our how-to on tuning your rig for optimal performance.

Photo: Bigstock

Spring is a time of prepping your boat for the coming season. While powerboaters fine-tune their engines, sailors should consider fine-tuning their rigs. Doing it yourself may seem intimidating, but it shouldn't be. Anyone reasonably handy can do it in a few hours. The reward is easier and faster sailing throughout the coming season.

Let's start with the basics for new sailors. With a few exceptions, a sailboat mast is held up by a series of stainless-steel wires. But those wires also perform several other equally important functions. When a sailboat is at rest and there is no wind blowing, the stress on these wires is very light with almost all the load downward toward the keel. However, when the boat is sailing and heeled over in a fresh breeze, more stress is placed on the wires and they have to work harder to hold the mast upright and stop it from bending.

The wires that prevent the mast from moving from side to side are called shrouds, and the ones that prevent fore and aft movement are called stays. The larger and taller the mast, the greater the load, and the number of shrouds and stays required. On a typical cruiser, say up to about 35 feet, there will generally be one forestay, one backstay, and two shrouds on each side.

To get the best performance from your boat and sails, the rigging needs to be set up correctly — often called "tuning the rig." The rig should be tuned with the boat in the water on a day with little to no wind. You'll also want to be away from wakes and other boats that can rock your boat. To start, the turnbuckles for the stays and shrouds should be hand-tight only. This is sufficient to hold up the rig but places no strain on anything — yet. Lay on your back on the boat's foredeck and sight up the front of the mast. It should be perfectly straight with no bends or kinks. Next, tighten the lower shrouds — these are the ones that do not go all the way to the top of the mast and often attach to the mast at the base of the crosstrees (the two horizontal spars at the upper ends of the topmasts).

You'll need a large screwdriver to rotate the turnbuckle, and a wrench to hold the shroud fitting and prevent it turning as you tighten. Give a couple of complete turns on either side. Have a helper release the main halyard and keep a little tension while you pull down the end that normally attaches to the mainsail until it just touches the top of the toerail adjacent to the chain plate. Have your helper cleat off the halyard, then swing the halyard over the boom and check the measurement on the other side. They should be the same. If not, adjust the turnbuckles until they the measurement is equal on port and starboard.

Adjusting and tuning a sailboat rig will often bring benefits such as easier handling and better performance.

Next do the same for the cap shrouds, these are the ones that go to the top of the mast, but note that due to the length of the shrouds, it is easy to bend the mast to either port or starboard. With the shrouds adjusted, sight up the mast one more time to ensure that it is still straight.

Next comes the fore and aft adjustment, which is made with the backstay and forestay. Masts should be plumb or lie back slightly. It should never rake forward. A good starting point is to tighten up the forestay and backstay a little over hand-tight. Use the main halyard as a plumb bob. Cleat off the halyard so the free end is just clear of the top of the boom and let it hang. If the shackle on the end of the halyard hits the mast, the mast is likely too far forward, so slacken off the forestay and tighten the backstay. Adjust a little at a time until the end of the halyard hangs free — 4 or 5 inches is a good starting point.

You'll need to install cotter pins into the turnbuckles to prevent them loosening over time, but before doing that, take the boat for a sail when the wind is blowing about 10 knots and see how everything works. With the boat on a beam reach, note the tightness of the windward shrouds. If they appear slack, they will need to be adjusted up. If the boat is hard on the tiller or wheel and tries to turn into wind, the mast has too much aft rake, so you'll want to slacken the backstay and tighten up on the forestay a little. If the bow wants to turn away from the wind, the mast is too far forward, so you'll need to move the mast back a little.

If you are at all unsure about tackling this task, play it safe and smart — seek out the services of a qualified rigger who has access to rig tension gauges and other specialized tools.

How to tune your rig for optimal performance

Optimizing the performance of your boat's rigging system is crucial for an enjoyable and safe sailing experience. This guide provides step-by-step instructions for tuning your rig and maintaining your sails.

How to Tune Your Rig for Optimal Performance

Sailing is an art that requires constant learning and adaptation. One of the most important aspects of sailing is ensuring that your boat’s rigging and sails are in top condition. In this article, we will discuss how to tune your rig for optimal performance, ensuring that you and your family can enjoy smooth sailing on your adventures.

Understanding the basics of rigging, the importance of rig tuning, step-by-step guide to rig tuning, sail improvements for better performance, maintaining your rig and sails.

Before we dive into the process of rig tuning, it’s essential to understand the basics of rigging. The rigging system on a sailboat consists of various components, including the mast, boom, shrouds, stays, and sails. These components work together to provide stability, support, and propulsion for your boat.

Mast and Boom

The mast is the vertical pole that supports the sails, while the boom is the horizontal pole attached to the mast’s base. The mast and boom are critical components of your rigging system, as they provide the framework for your sails.

Shrouds and Stays

Shrouds and stays are the wires or ropes that connect the mast to the boat’s hull. They provide lateral and fore-and-aft support for the mast, ensuring that it remains stable and upright. Shrouds are typically attached to the sides of the boat, while stays are connected to the bow and stern.

Sails are the primary means of propulsion for a sailboat. They work by capturing the wind’s energy and converting it into forward motion. There are various types of sails, including mainsails, jibs, and spinnakers, each with its own unique characteristics and uses.

Rig tuning is the process of adjusting your boat’s rigging system to achieve optimal performance. Proper rig tuning can significantly impact your boat’s speed, handling, and overall sailing experience. Some of the benefits of rig tuning include:

Improved boat speed and pointing ability
Enhanced sail shape and efficiency
Reduced wear and tear on rigging components
Increased safety and stability

By regularly tuning your rig, you can ensure that your boat is always performing at its best, allowing you and your family to enjoy your sailing adventures to the fullest.

Rig tuning can be a complex process, but with the right knowledge and tools, it’s something that any sailor can learn to do. Here’s a step-by-step guide to help you tune your rig for optimal performance:

Step 1: Inspect Your Rigging

Before making any adjustments, it’s essential to inspect your rigging for signs of wear, damage, or corrosion. Check all components, including the mast, boom, shrouds, stays, and sails, for any issues that may affect your boat’s performance.

Step 2: Set Your Mast Rake

Mast rake refers to the angle of the mast relative to the boat’s centerline. Adjusting the mast rake can have a significant impact on your boat’s balance and performance. To set your mast rake, follow these steps:

Attach a weight to your main halyard and let it hang freely over the side of the boat.
Measure the distance from the halyard to the boat’s centerline at the chainplates.
Adjust the forestay and backstay until the desired rake is achieved.

Step 3: Adjust Your Shrouds and Stays

Next, you’ll need to adjust your shrouds and stays to ensure proper mast alignment and tension. Follow these steps:

Loosen all shrouds and stays.
Tighten the upper shrouds until the mast is straight from side to side.
Tighten the lower shrouds to remove any side-to-side play in the mast.
Adjust the forestay and backstay to achieve the desired mast bend.

Step 4: Check Your Rig Tension

Proper rig tension is crucial for maintaining sail shape and boat performance. To check your rig tension, follow these steps:

Attach a tension gauge to your shrouds and stays.
Measure the tension in each wire, adjusting as necessary to achieve the desired tension.
Ensure that the tension is even on both sides of the boat.

Step 5: Fine-Tune Your Rig

Once your rig is properly tensioned and aligned, you can make any final adjustments to optimize performance. This may include adjusting your sail controls, such as the outhaul, cunningham, and vang, to fine-tune sail shape and efficiency.

In addition to rig tuning, there are several sail improvements that you can make to enhance your boat’s performance. Some of these improvements include:

Upgrading to high-quality sails made from durable, lightweight materials
Regularly cleaning and inspecting your sails for signs of wear or damage
Using sail battens to improve sail shape and efficiency
Installing a roller furling system for easier sail handling and storage

By investing in these sail improvements, you can ensure that your boat is always performing at its best, allowing you to enjoy your sailing adventures to the fullest.

Regular maintenance is essential for keeping your rig and sails in top condition. Some maintenance tasks to consider include:

Inspecting your rigging for signs of wear, damage, or corrosion
Lubricating moving parts, such as sheaves and blocks, to reduce friction and wear
Replacing worn or damaged components, such as shrouds, stays, and sails
Regularly cleaning your sails to remove dirt, salt, and other contaminants

By staying on top of these maintenance tasks, you can prolong the life of your rig and sails, ensuring that your boat is always ready for your next adventure.

Tuning your rig for optimal performance is an essential skill for any sailor. By following the steps outlined in this article, you can ensure that your boat is always performing at its best, allowing you and your family to enjoy your sailing adventures to the fullest. Remember to regularly inspect and maintain your rig and sails, and don’t be afraid to make improvements and adjustments as needed. With the right knowledge and tools, you can transform your boat into a high-performance sailing machine that’s ready to take on the open sea.

Sailboat Masts: A Comprehensive Guide to Choosing the Perfect Mast

by Emma Sullivan | Jul 17, 2023 | Sailboat Gear and Equipment

Short answer sailboat masts:

Sailboat masts are vertical structures that support the sails on a sailboat. Typically made of aluminum, wood, or carbon fiber, masts vary in length and design depending on the type and size of the boat. They play a crucial role in providing stability and transferring wind energy to propel the sailboat forward.

Understanding Sailboat Masts: A Comprehensive Guide

When it comes to sailing, one of the most critical components of a sailboat is its mast. Acting as the backbone and support for the sails, the mast plays a crucial role in harnessing wind power to propel the vessel forward. In this comprehensive guide, we will delve into the intricacies of sailboat masts, exploring their various types, materials, and functions.

Types of Sailboat Masts: Sailboat masts come in different designs, each catering to specific sailing needs. The most common types include:

1. Deck-Stepped Mast: This type of mast is attached to the deck and supported by compression or tension on its base. It offers ease of access for maintenance but may restrict height due to deck limitations.

2. Keel-Stepped Mast: As the name suggests, this mast rests on the keel, providing increased stability and maximizing height potential. However, accessing it can be more challenging for routine inspections or repairs.

3. Fractional Rig: With a fractional rig setup, the forestay attachment point is positioned below the top of the mast’s highest point. This design allows for a wider range of sail adjustments while enhancing performance in varying wind conditions.

4. Masthead Rig: In contrast to a fractional rig, a masthead rig positions its forestay at the top of the mast’s highest point. This configuration provides greater cruising stability while sacrificing some versatility in sail adjustments.

Materials Used in Sailboat Masts: Sailboat masts are predominantly crafted from three main materials:

1. Aluminum Alloy: Highly popular due to its durability and affordability, aluminum alloy masts offer excellent strength-to-weight ratio while ensuring resistance against corrosion brought by saltwater exposure.

2. Carbon Fiber: Known for its superior strength properties combined with lightweight qualities, carbon fiber has become synonymous with high-performance racing sailboats. It offers exceptional stiffness and flexibility, allowing sailors to optimize speed and response.

3. Wood: While less common in modern sailboats, wood masts were extensively used in the past. Today, they tend to be preferred for traditional or classic boats seeking a touch of nostalgia. Wooden masts require regular maintenance to prevent rot and warping.

Functions of Sailboat Masts: Sailboat masts serve several key functions; these include:

1. Supporting the Sails: The primary purpose of a mast is to provide a stable platform for the attachment and hoisting of sails. It must withstand varying wind pressures and distribute forces evenly throughout the structure.

2. Channeling Wind: By placing the sails on the mast, it acts as an optimal conduit for capturing wind energy and converting it into forward propulsion. The design of the mast plays a role in determining how efficiently this process occurs.

3. Controlling Rig Tension: Masts often have additional components like shrouds, stays, or running rigging that allow sailors to adjust tension in their sailboat’s rigging system. Correctly tensioned rigging helps maintain sail shape, control stability, and overall boat performance.

4. Providing Height for Obstacle Clearance: Whether sailing under bridges or navigating tight spaces near shorelines, the height provided by a well-designed mast allows sailboats to clear obstacles safely without damaging the vessel or jeopardizing crew safety.

Understanding these aspects of sailboat masts can empower sailors with knowledge critical both for enhancing performance and ensuring safe navigation on open waters. So next time you set foot on a sailboat, take a moment to appreciate how this seemingly simple structure can make all the difference in your sailing experience!

How to Choose the Right Sailboat Mast for Your Vessel

When it comes to sailing, the mast of your sailboat is like its backbone. It provides crucial support for the sails and allows you to harness the power of the wind, propelling you through the water with grace and speed. But choosing the right sailboat mast for your vessel can be a daunting task, considering the myriad options available in today’s market. Fear not, dear sailors, for we are here to guide you through this process and help you make an informed decision.

First and foremost, it’s important to consider the material of the mast. Common options include aluminum, carbon fiber, and wood. Aluminum masts are popular due to their affordability and durability. They can withstand various weather conditions while offering excellent structural integrity. On the other hand, carbon fiber masts are lightweight and have high tensile strength, resulting in improved performance on the water. Although they tend to be more expensive than aluminum masts, their benefits make them an attractive option for serious sailors looking to gain a competitive edge.

Next up is height – size matters! The height of your mast directly impacts your boat’s speed potential and overall performance. Taller masts generate more sail area but also require stronger rigging systems to handle increased loads. If you’re planning on leisurely coastal cruising, a shorter mast may suffice; however, if you’re aiming for bluewater or racing adventures where every knot counts, opting for a taller mast might be wise.

Additionally, understanding your sailing goals and preferences is crucial when selecting a mast profile or shape that suits your needs best. Do you prefer easy handling? A single-spreader rig could be ideal as it provides simplicity in terms of tuning and maintenance. Alternatively, if you’re after enhanced control and better downwind performance during races or offshore voyages, go for a double-spreader configuration that offers improved stability and versatility.

Now let’s talk about section shape – it’s time to get curvy! Masts come in various shapes, from round to elliptical, and even with full or square sections. The choice here will depend on your boat’s design and your sailing intentions. Round masts are known for their strength and versatility across different wind conditions. They offer a balanced compromise between performance and ease of use. On the other hand, an elliptical or oval shape provides improved aerodynamics, reducing drag and potentially enhancing speed.

Last but not least, don’t forget about the mast’s finishing touches – fittings and accessories. These seemingly small details can have a huge impact on both functionality and aesthetics. Stainless steel fittings are durable but can add unwanted weight, whereas lightweight alternatives such as titanium or carbon fiber offer strength without sacrificing performance.

In conclusion, choosing the right sailboat mast requires careful consideration of material, height, profile shape, and fittings. By understanding your own sailing objectives, preferences, and budgetary constraints, you can make an informed decision that will elevate your sailing experience to new heights (pun intended!). So weigh anchor and set sail on a journey of discovery with the perfect mast for your vessel!

Step-by-Step: Installing and Rigging Sailboat Masts

Welcome back to our sailing blog, where we aim to give you the best tips and tricks for all your seafaring adventures. Today, we dive into the intricate world of installing and rigging sailboat masts. Whether you’re a seasoned sailor or just starting out, this step-by-step guide will help you navigate the process with ease.

Step 1: Gather Your Tools

Before you begin, it’s essential to assemble all the necessary tools for the job. You’ll need a measuring tape, wrenches of various sizes, shackles, cotter pins, a winch handle, and line cutters. It’s always a good idea to have these tools readily available on your boat so that when it comes time to install or adjust your mast, you won’t waste any precious time rummaging through cluttered storage compartments.

Step 2: Measure Twice, Cut Once

The old adage holds true in sailboat mast installation as well. Before taking down your current mast (if applicable), measure its height from deck level accurately. This measurement is crucial as it determines whether your new mast will fit correctly onto your boat. Remember to account for any changes in boat specifications since the last mast installation.

Step 3: Prepare Your Mast and Deck Fittings

Now that you have all the measurements required; carefully inspect your new mast for any defects or damages during transportation. Ensure that all fittings are secure and correctly attached before proceeding further. Take note of any loose shackles or cotter pins that may need tightening or replacing.

Next up is preparing your deck fittings for receiving the new mast. Check that they are clean, well-lubricated, and free from any obstructions such as dirt or rust build-up. A properly prepared base will ensure smooth sailing throughout the installation process.

Step 4: Hoisting Your Mast

With your deck fittings ready, it’s time to hoist the mast into position. This task is easier with a team of two or more experienced sailors, so don’t hesitate to seek help. Carefully attach a halyard to the top of your mast and securely fasten it using shackles or appropriate knots. Slowly raise the mast, ensuring that it remains vertical at all times.

As you lift the mast, have someone guide the base onto its designated deck fitting. Ensure proper alignment and fit by carefully wiggling and adjusting as needed. Once in place, secure the base with robust cotter pins or other locking mechanisms.

Step 5: Attaching Shrouds and Stays

Now that your mast is secure, it’s time to attach the shrouds and stays – those vital support cables that keep everything steady while on the water. Begin by attaching each stay or shroud to their designated point on deck using appropriately sized shackles.

One by one, extend each cable from its anchor point on deck up towards its designated attachment point on the mast. Ensure that these cables are correctly tensioned without any sagging or excessive tautness. Use your wrenches to tighten all turnbuckles until they’re firm but not overly tightened.

Step 6: Trimming Your Sails

With your sailboat mast fully installed and rigging completed, it’s time for some final checks before setting sail! Make sure all lines are properly secured with correct tension – avoid overtightening which may distort sails’ shape when under wind pressure.

Double-check all connections for safety purposes—no loose shackles or cotter pins left behind. Lastly, trim your sails to optimize performance; adjust halyards and sheets as necessary for proper sail shape.

Final Thoughts

Installing and rigging sailboat masts may seem like an overwhelming task initially, but with careful planning and attention to detail, anyone can accomplish this feat. Remember to take your time and don’t rush the process; safety should always be your top priority.

We hope this step-by-step guide has shed some light on the intricacies of mast installation and rigging. Stay tuned for more informative blog posts to make your sailing experience even more enjoyable!

Exploring Different Types of Sailboat Masts and Their Benefits

When it comes to sailing, one of the most important parts of a sailboat is its mast. Acting as the central structural support, the type of mast you choose can greatly influence your sailing experience. In this blog post, we will dive into exploring different types of sailboat masts and uncovering their unique benefits.

1. The Classic Tall Mast: The tall mast design is reminiscent of traditional sailing vessels and offers a timeless appeal. It provides increased sail area for harnessing stronger winds and achieving higher speeds. With a tall mast, you’ll be able to take advantage of more wind power, making it an ideal choice for those who crave exhilarating speed on the open water.

2. The Bendy Mast: In contrast to the rigid nature of traditional masts, bendy masts have become increasingly popular among sailors seeking enhanced performance. By incorporating flexible materials or engineering techniques into its construction, the bendy mast allows for greater control over sail shape and camber adjustment. This flexibility ensures optimal airflow around the sails, resulting in improved maneuverability and responsiveness.

3. The Carbon Fiber Mast: For those craving both strength and lightness in their sailboat’s mast, carbon fiber is an unmatched material choice. Carbon fiber masts offer exceptional stiffness-to-weight ratios, allowing sailors to maximize their vessel’s overall performance potential.

4. The Fractional Rigging System: Moving away from individual mast types per se but closely linked to what’s atop your boat is fractional rigging system designs. These systems involve attaching the forestay (the cable supporting the front portion of the mast) at some point below the top; this configuration results in reduced stress on both the boat and crew during gusts or high winds. The fractional rig also enables easy depowering by adjusting halyard tension without compromising pointing ability or sail trim.

5. The Wing Masts: Looking to embrace cutting-edge sailing innovations? Look no further than the wing masts. Popularized in high-performance racing sailboats, they provide superior aerodynamic efficiency due to their streamlined shape. By reducing drag and turbulence, wing masts allow sailors to achieve great speeds while experiencing reduced heeling forces—an excellent choice for those seeking both speed and stability in their sailing adventures.

In conclusion, choosing the right type of sailboat mast is crucial for optimizing performance, speed, maneuverability, and overall sailing experience. Whether you opt for the classic tall mast for a traditional appeal or choose a carbon fiber mast for strength and lightness, there are various options available to suit your preferences. Exploring different types of sailboat masts opens up a world of possibilities, each offering its unique benefits that can elevate your sailing journey to new heights – quite literally!

How To Prioritize Your Sailboat’s Spring Checklist

By Ralph Najaro
April 11, 2024

A countdown begins as soon as your boat’s seasonal launch date is set. The more experienced the sailor, the earlier it starts. For months before the first flowers bloom in springtime, sailors tackle major projects by rolling up their sleeves and hiring pros for installations, major engine work, and complex upgrades. The bottom is painted, and the operational checks are completed to make sure everything is in good working order.

Those are the key elements of a true spring commissioning—not adding an electronics network or deciding that the rudder needs replacing. It’s equally inappropriate to use this time only for cosmetic restoration.

Instead, spring commissioning should focus on ensuring systems reliability and seaworthiness. Varnishing the coamings and handrails can be shifted to the post-launch project list, but replacing a corroded, leaking through-hull fitting or a worn-out cutlass bearing must take precedence.

Bottom Paint

Bottom painting is synonymous with spring—at least for saltwater sailors who haul their boats each fall. Hopefully, the pressure washdown cleared away the fauna and flora, and the remaining bottom paint is well-adhered. If so, paint prep involves a minor amount of scuff sanding, which can be done the old-fashioned way: hand-sanding with 80-grit sandpaper.

This can be an arduous task, even with the whole crew participating. It’s ideal to rent a vacuum-extraction random orbital sander. This tool will maximize labor efficiency and minimize the airborne dust plume. In many parts of the country, drop cloths or full matting beneath boats is mandatory.

When it comes to working with antifouling coatings, keep the old paint residue, as well as the new coating chemistry, off your skin and out of your respiratory system. Gloves, coveralls, a hat and eye protection will go a long way.

Masking up is another priority. Disposable particle filter masks must fit facial contours, and it’s important to swap old masks for new ones regularly. Paint companies usually provide helpful details in their literature. In most cases, volatile solvents are the major concern. Avoid painting in confined spaces such as under a tented hull.

Paint selection depends on where you sail and how much of the year your boat spends in the water. For eco-friendly biocides, progress has been made in formulating super-slick coatings and paints that slough off along with the critters. In warm marine environments, Bryozoa have become a major bane to sailors. Some less-toxic bottom paints work on fast-planing powerboats, but slower-cruising sailboats are best served by hard or soft ablative coatings.

Unfortunately, more and more boatyards are prohibiting DIY bottom work. Some yards provide hauling and blocking, and still let clients immerse themselves in the DIY tradition. At other yards, make sure to get a firm quote for what the yard will do, what paint will be used, and the number of coats. Also seek out feedback from friends who have used the service.

Gelcoat is an unsung hero in fiberglass-boat building. It can weather a decade of abuse from the elements with a minimal amount of maintenance. Fastidious sailors use compounds, polishes and waxes to further extend the gelcoat’s life span.

At its core, gelcoat is a specialized resin that’s sprayed onto the hull mold. As the polymerization process unfolds, solvents leave the gelcoat via the inner surface (the side farthest from the mold). This process ensures that the layer against the mold develops into a glossy, much-less-porous stain-resistant outer skin.

Excessive use of overly abrasive compounds removes too much of this hard outer layer. A good way to renew gelcoat gloss is to begin with a freshwater wash to dislodge loose grit. Follow up with a sponge, soft mop, or other nonabrasive scrub with a mild boat soap or dish detergent. The goal is to clean away grit without resorting to scrub pads and harsher detergents.

Once this initial washdown is complete, note where the challenges lie. If there are rust stains, don’t attempt to scrub them away. Instead, use an oxalic acid gel to remove the rust stains chemically. In areas that appear greasy and sticky, try hot water with boat-washing detergent. If necessary, use Goo Gone, followed by a wash and rinse.

Newer gelcoats respond well to nonabrasive gloss-restoration products. For the first few years, waxing and buffing after a thorough washing is all it takes. If you use a power buffer, avoid high rpm rotation that can overheat and damage the gelcoat.

The longer you can avoid the use of abrasive compounds, the better, but the day will come when oxidation leaves the gelcoat chalky, and the next step is to compound the surface with as fine a grit as will do the job. This restorative effort results in a satin-finish look.

Eventually, the oxidation and compounding cycle removes too much gelcoat, necessitating a topside face-lift, usually in the form of a linear polyurethane paint job.

Rigs and Rigging

Before there were Travelifts and Brownell boat stands, sailboat storage involved stepping and unstepping the mast annually. The cost savings of mast-stepped storage is significant, but spars and rigging do not always get the scrutiny they deserve. This is why the spring-commissioning agenda should include a top-down rig and rigging inspection.

Going aloft safely involves techniques that vary from rigger to rigger. Most agree that a climbing harness is better than a boatswain’s chair and that the skill of the crew handling the halyards on deck is important.

Spring commissioning should focus on ensuring systems reliability and seaworthiness—not adding an electronics network or replacing a rudder.

Focus on components that hold up the mast, and on the running rigging used to set, furl and trim sails. Most inspections start at the masthead and work their way down to the deck. The process includes scrutiny of cotter and clevis pins, and a search for chafe and corrosion around halyard sheaves.

Also look for halyard wear, especially near the roller-furling headsail’s top swivel. While aloft, test the navigation lights and wind instruments.

During your slow descent, take a close look at spreaders and their mast-mounting hardware. This quick rig check is not as revealing as an unstepped-mast inspection would be, but it does offer a chance to catch and remedy potentially serious problems.

Overall, a successful spring commissioning means there’s no water accumulating in the bilge, the helm is responsive, and a dozen or so other key operational attributes continue to function as designed.

What type of sailing boats are used at the Olympics?

Ilca 6 and ilca 7.

Designed by Bruce Kirby in 1969, the ILCA 7 contributed to a huge increase in recreational sailing because of its speed, affordability and easy maintenance. Relatively lightweight, the boat is 4.23 meters long (approximately 13 feet 9 inches) with a 7.06 square meter mainsail (approximately 76 square feet).

Making its Olympic debut in 2008, the ILCA 6 is essentially a smaller version of the ILCA 7, using the same fiberglass hull. With a shorter lower-mast and a sail 14 feet smaller than that of the ILCA 7, the boat is more conducive for lighter sailors, making it a great boat for women's racing.

An Olympic class since the Montreal Games in 1976, the boat was originally designed by French architect Andre Cornu in 1963, and was named after its length: 4.70 meters (approximately 15 feet). The two-person centerboard dinghy is malleable to all levels of sailors and is used both recreationally and competitively around the world.

The boat's light frame makes it responsive to movements of the sailors, and thus the skipper and the crew generally complement each other in weight. Three sails are used: the main, jib and spinnaker. Typically taller and heavier than the skipper, the crew hangs out on the trapeze to balance the boat depending on the conditions.

Originally an open-class boat, the event was divided in 1988 when the women's 470 was introduced. Starting at the Paris 2024 Games, the boat will be sailed by a mixed-gender crew for the first time.

NACRA started in the U.S. as an acronym for "North American Catamaran Racing Association" in 1975. Selected by the International Sailing Federation (ISAF) in May 2012 as the equipment for the mixed multihull event, the Nacra 17 made its Olympic Games competition debut at the Rio Games.

The Nacra 17 was created fully in line with the specifications given by ISAF. An agile high speed machine, the hull of the Nacra 17 measures 5.25 meters long (approximately 17 feet, 2 inches), the beam measures 2.59m long (approximately 8-6) and the mainsail has an area of 14.45 square meters (approximately 155 square feet). The curved daggerboards add a distinct dimension to the multihull catamaran making for reduced sheet loads and mitigating the impact of the crew weight.

Designed by Australian Julian Bethwaite specifically for the 2000 Games in Sydney, the 49er is a high speed, high performance boat.

The name of the 49er derives from its hull length of 4.99 meters (approximately 16 feet). A mainsail, jib, and spinnaker comprise the three sails of this two-person skiff. It has twin trapezes and retractable wings that spread 2.74 meters (approximately 9 feet) in width, giving the boat the appearance of a manta-ray. The trapezes allow the crew to use their weight to balance the boat. With a 38 square meter spinnaker area (approximately 409 square feet), it is very large for such a small boat, making the 49er one of the fastest at the Olympics. While its speed is certainly a draw, the 49er is also one of the hardest boats to operate and requires agility and successful teamwork, without which the boat can easily flip.

Developed by Mackay Boats, the FX rig was trialed and selected by the ISAF as the women's 49er event for the Rio Games. The FX was specifically designed to accommodate lighter crews and be perfectly suited for the 49er hull. Similar to its 49er counterpart, the 49erFX is a high performance skiff that demands athleticism, skill and balance. The FX mast height is 7.5 meters (approximately 24 feet), with the mainsail measuring 13.8 square meters (approximately 149 square feet).

What type of boards are used at the Olympics?

iQFoil is the newest windsurfer class and will make its Olympic debut at the 2024 Paris Olympics, replacing the RS:X class, which had been a staple of Olympic windsurfing for years. It involves windsurfers equipped with hydrofoils, known as foiling boards, which lift the board out of the water to reduce drag and increase speed. The average speed of the iQFoil is approximately 42 km/h (26 mph), which is significantly faster than the RS:X. In order to achieve maximum speeds, a high level of focus on balancing the board is essential.

The iQFoil performs best in light winds. The board is wider and shorter than the RS:X, making it compact and agile.

IKA Formula Kite

Also making its Olympic debut in Paris is the kiteboarding class Formula Kite. Similar to the iQFoil, Formula Kite also involves hydrofoils. Kiteboarders use a large controllable kite to propel themselves across the water on a small surfboard-like board. The design of Formula Kite boards prioritizes stability, control, and efficiency, enabling competitors to maneuver quickly and smoothly across the water while harnessing the power of the kite.

The boards are typically lightweight and highly responsive, allowing for precise control during the race.

Frequently Asked Questions

Do olympic sailors use their own boats.

Typically, all boats and equipment are provided by the organizing committee of the Olympic Games or by event organizers. For each class or event, a fleet of class-approved boats are made available for training and racing. This ensures a level playing field for all. However, competitors may bring their own personal equipment, such as sails, rigging, and personal gear.

What equipment is used for Olympic sailing?

In addition to the boats or boards used at the Olympics, competitors also use sails and rigging specific to their boat. (These include mainsails, jibs, the mast, the boom and rigging components like sheets, halyards, and control lines.)

Competitors are also required to wear appropriate safety gear including personal flotation devices, wetsuits or drysuits, and helmets in some classes. Competitors may also use GPS devices and radios to aid in racing and communication with support boats or race officials.
