Introduction

The Laser Dinghy, a one-design racing sailboat, was designed by Bruce Kirby and unveiled to the public at the 1971 New York Boat Show. Since then 200,000+ Lasers have been built to date and are sailed across 140+ countries, with its popularity being primarily due to its simplicity and performance.

The original concept for the Laser centered on creating a boat that was easy to build, sail, and purchase, thereby making it accessible to a broad range of sailors. The Laser quickly gained popularity and became the boat of choice for many sailing schools and clubs worldwide. It also rapidly gained recognition as a racing boat and debuted as the single-handed open-class dinghy in the 1996 Olympic Games.

Racing is very competitive due to the one-design restrictions, which means sailors are truly able to test their ability, rather than rely on differences in hull shape, sails, and other gear to gain an advantage.

Besides being used for competition, the Laser is a popular choice for recreational sailing. You can spot these dinghies on lakes, rivers, and oceans worldwide. With its one-design nature, ease of use, and practicality, the Laser Dinghy is set to remain a popular sailboat for many years to come.

The Laser Dinghy – 3 Sailboats In 1

The laser dinghy comes in 3 rig sizes:

• 4.7 / ILCA 4
• Radial / ILCA 6, and
• Full/Standard / ILCA 7 rig

This means that sailors of just about any ability or age can enter the sport, and advance with minimal cost.

Rigging is easy using a sleeved sail over a mast with no stays, and can be launched and sailed single-handedly with ease. Minimal parts mean minimal breakages and maintenance.

The Laser 4.7 / ILCA 4…

utilizes a smaller sail than the Standard rig (4.7m 2 / 50.6 ft 2 which is 33% smaller) and a shorter pre-bent lower mast section.  It is ideal for lighter sailors (up to 121lb / 55kg) and beginners.

The Laser Radial / ILCA 6…

uses a smaller sail than the Standard rig (5.76m 2 / 62 ft 2 which is 18% smaller) and a shorter more flexible lower mast section. It is suitable for sailors between about 121lb – 154lb / 55kg – 70kg. The Radial is the most popular class of Laser, as it is suitable for the largest amount of people, including youth, women, and masters. The radial sail can easily be identified by the sail cut in a radial pattern emanating out from the clew.

The Laser Standard / ILCA 7…

has a 7.06m 2 / 76 ft 2 sail, and is more suitable for sailors above about 143lb / 65kg. This rig is suited to heavier sailors in windy conditions where weight, strength, and fitness are critical.

I am switching my boat from sailing 470 to sailing a laser now. I intend to sail laser primarily to qualify for the Olympics.

My question is if my height is good enough to sail laser standard. My height is 167 cm (5 ft, 6 inches) and weight is 68kgs.

Thanks, Vincent

Hi Vincent. Thanks for your question. I would say that at 167 cm and 68kgs, you would be at the lighter/shorter end of the scale for sailing a full rig laser. You may be able to put on some bulk before the next Olympics to handle it a bit easier. I think everyone has different opinions on what is the ideal weight for a laser. A lot depends on the conditions and your skill. Just for your info, I did some research on stats for Australia’s gold medalist at the 2012 London Olympics Tom Slingsby. He was reported to be 83kg & 186cm at the time. Good luck with it, and all the best. Brendan

My Grand daughter would like to switch froom sail Terra to Laser. What is the minimum height for the class

Hi Norman Thanks for your question. I’m not sure that there is a minimum height. It’s more about the weight. For a Laser 4.7, the ideal weight is around 110-130 lbs (50-58 kg). Any lighter and she may have trouble keeping it flat in a breeze. cheers Brendan

Hi, I am looking to buy a laser and am 5ft 10 (178cm) and around 68kg, I sail in a harbour so short chop is the worst condition, do you think I’m big enough for a standard?

Hi Giles I don’t think it’s as much about the height as it is the weight. At 68kg, you might be a little on the light side for a full rig. But it depends on how windy it tends to get also. If it’s generally pretty windy, you might struggle, but if it’s often fairly light, you may be ok. This thread has a good discussion on the ideal weight for laser standard sailor. Hope that helps. Brendan

Hi My sea scout troop has taken possession of a Laser 2. It lacks a suit of sails and a rudder. talking to others, no one is sure if the rudders are identical to Laser 1’s. Can you advise?

Hi Pete Thanks for your question. I am not very familiar with the Laser 2, so did some research. However, it was very hard to come up with information on the Laser 2 specs. From what I could tell, the rudders are different between the Laser & Laser 2, however, I was not able to find the actual specs on the Laser 2 rudder. For a measurement diagram for the Laser rudder, click here (click on the “Mast Top Section, Boom and Foils” tab). For an image of the Laser II rudder, check this out . As you can see, it looks slightly different to that of the standard Laser rudder . Sorry I can’t be of more help than that. Maybe some other readers can provide some more info. cheers Brendan

Hello, I am 6 feet tall and weigh 53 pounds, what laser whould be good for me?

Hi Alessandro Thanks for your question. I hope you mean 153lb, and not 53lb!! Opinions vary, and it depends on your fitness and ability. If you are just starting out, you may be best suited to a Radial Laser, but you are in the overlap zone between the Radial and Full rigs. So it depends a lot on your experience and fitness. It can also depend on where you live. If it tends to be quite windy on a regular basis, then you may opt for a smaller rig. Conversely, if it’s often quieter on the water, then a bigger rig may help. I’m a few lb/kg heavier than you, and I have a full-size / standard Laser rig. I find it’s great for the lighter days, but can be a bit overpowered on the heavier days. I don’t mind though, as it just makes it more exciting when you go around the top mark. cheers Brendan

Hi I’ve just brought a laser with a radial sail but a Standard mast. I was gonna make a Radial mast out of the right alloy tube but I need the measurements. Would anyone know what is The length of a radial mast?

Thanks Kaleb

Hi Kaleb Here are the measurements for the different Laser masts for each of the top and bottom sections. cheers

How tall is the mast on the “std” Laser? I had one once and it was fun getting it into the hole on the hull! Cliff

Hi Cliff Yes, it can take a bit of getting used to, when putting the mast into the mast step. Looking at this site , the total laser mast length should be approx.: – top section (including top plug) = 3600 – 305 = 3295mm – bottom section (including base plug) = 2865mm Overall laser standard mast length = 6160mm / 20.2 ft (approx.) Hope that helps!

Hi, I am 155 cm tall and weigh 49 kg. Am I suitable for sailing a laser 4.7 or should I sail a 420?

Hi D I’m not an expert with the 420. For a laser 4.7, I think you would be a bit on the light side, but it also depends on how fit, strong, and experienced in sailing you are. It may also depend, to some extent, on where you live (some places are windier than others)… if you have a strong sea breeze every afternoon, then this may be too much.

Hi, I’m a fairly experienced optimist sailor and I need to change my class due to my age. I am 157 cm tall and I weigh 46 kg. Would I be able sail a laser 4.7? The place I live can get very windy at times. Thank you

Hi Defne I think a 4.7 should be ok, but it would depend on your experience and level of fitness. Since you say that you are a fairly experienced optimist sailor, then that will definitely help. You might struggle a bit on the windy days though. If you can, ask around your local club and try to take a 4.7 out for a spin. Let us know how you go! All the best.

Hi I sail optimists and are looking into a laser as the next boat. I weigh 122 pounds and was wondering if I should get a radial or a 4.7 rig

Hi Noah Your situation is similar to the previous comment in June, so not sure if you saw that. It depends on a few things… including how experienced you are, how fit and strong you are, and what the typical conditions are like where you sail. At your current weight, you’re probably at the lower end of the ideal weight range for a radial. But if you are young and still growing, you might want to get the radial and grow into it over the next year or so. But you might struggle a bit at 1st on the windy days. See if you can take one of each out for a spin and give it a test for yourself. Best of luck with it!

Hello I have a Laser Radial sail with a “33” number above the boat sumber. the boat number is 177137 so its not an abbreviation of that … do you know what the 33 means? Thanks!

Hi Russ I’m not sure what the “33” about the boat number would refer to. Maybe some other readers may be able to help? Sorry I can’t help more than that. All the best with it.

Hi. I am currently building an El Toro dinghy. I do not want to have to handle the full 14 foot one-piece mast. I read somewhere that you can retrofit a laser 4.7 mast and sail onto an El Toro hull. A Sabot boom is marginally cheaper than a laser 4.7 one, and I was wondering if a laser 4.7 mainsail would fit a sabot boom. Thanks!

Hi Alexander I am not an expert on sabots, but from my research… The Laser 4.7 sail has a foot of 2.48m / 8.1ft. The sabot sail has a foot of 7ft and a boom of 7′ 3″. So the sabot boom looks too short for a Laser 4.7 sail.

Can anyone please tell me in what year Laser #66750 would have been made?

Hello Steve According to research that I had done previously, it looks like sail number 66750 would have been made in 1979. See this link for more info. cheers Brendan

Hi, I have sailed Sunfish sailboats, and years ago I crewed for a friend on his J24 in PHRF races. I love the idea of excitement when I sail, but I would also like to be able I sail with a passenger. Can a Laser be sailed with a passenger for entertainment? I did not see anything about the maximum capacity of the hull. Doug

Hello Doug A Laser sailing dinghy is designed as a single-handed boat, meaning it is typically meant to be sailed by one person. However, it is possible to sail a Laser dinghy with two people, although it may not be the most efficient or optimal way to use the boat. It is only a small dinghy, so the extra weight will affect the performance. There is not much room in the cockpit for 1 person, so for 2 people, it will be even more cramped. If you just want to go out and have some fun (and you and your passenger aren’t too big), then you can probably do that. But there are many other dinghies available that are specifically designed for two-person sailing that would be a better option.

Hello, I am looking for the width of the bottom part of the mast, to design a fitting for a wind indicator. Although I have looked through many sites (including the ones linked in the comments), I can’t find the specific measurements. James

Hello James The Laser mast diameter is approx. 2.5″ or 64mm.

I holiday in Finland and have just been given a laser to use but I need a hand trolley to get it over the stones on the shore. When I had a laser before many years ago, I had a light hand trolley made with plastic tubing. Do you or anyone else have a model on how to make one? I have wheels

Hello Brian I do not have any plans or instructions, but there are a few forums that discuss how to make a homemade dolly. Check out some examples here and here . Otherwise, there are new dollies for sale. Have a look at this page for more info. cheers

ILCA 4 Sail Number and Letter Diagram (PDF )

ILCA 6 Sail Number and Letter Diagram (PDF)

ILCA 7 MKII Sail Number and Letter Diagram (PDF)

ILCA 7 MKI Sail Number and Letter Diagram (PDF)

Red Rhombus for Women’s Events (PDF)

Jean-Luc Michon has put together some videos to help with placement of sail numbers and country letters for the ILCA 7 and ILCA 6 sails.

Style and Color

Only self-adhesive, stick on sail numbers and letters may be used. Each one shall be a single, solid color, and easy to read. The last four numbers on both sides of the sail shall be the same dark color, preferably black. The numbers in front of the last four shall all be another, obviously different color, preferably red. National letters are only required at international events, and shall all be the same color.

Preparation

If the sail is not new, it should be sponged clean with mild soapy water, rinsed and dried. Find a large, clean, flat, hard surface to work on, such as a table or clean wooden floor.

Make a template that each number will just fit inside. See the Positioning Diagrams for the minimum sizes of numbers and letters, and template details. They are different for each of the Standard, Radial and 4.7 sails. The template is a rectangle for upright numbers, and a parallelogram for angled numbers.

Base Lines and Limit Lines

Use a pencil to lightly draw Base Lines and Limit Lines on the sail. The bottom of each number and letter must lie on a Base Line . The Limit Line is parallel to the leech of the sail, and 100mm from it. The closest letter or number to the leech is positioned to just touch the Limit Line. This is shown as the Start Point on the Positioning Diagrams. The number or letter should touch the Limit Line at the Base Line or at any other height, depending on its shape.

Starboard Side Numbers and National Letters

• Spread the sail out flat on the working surface so that the starboard side of the sail is facing up. The leech (back edge of the sail) will be on the left hand side as shown in the Positioning Diagrams.
• Make sure you are using the correct diagram for the design of sail you are applying the numbers to . Draw the Base Line and Limit Line for the starboard numbers (and letters) as shown on the positioning diagram.
• Before peeling off the backing, place the bottom of the first number on the Base Line , with the Start Point touching the Limit Line . Use the template with its bottom edge on the Base Line to make sure the number is at the correct angle. Pencil around the outline of the number.
• Peel and fold back about 10mm of the backing from the bottom of the number. Place the number within the pencil outline and press down to stick the peeled back area. Lift the remainder of the number and slowly peel off the backing as you smooth the number onto the sail, taking care to remove air bubbles and creases as you go.
• If the first number you applied was a 1 (one), measure from the bottom right corner of it and mark a point the space width away along the Base Line . The space width is 60mm for Standard and Radial rig sails, and 40mm for 4.7 sails – see the appropriate Positioning Diagram. Place your template on the Base Line with its lower left corner on the new mark and pencil round the outline of it. Before peeling off the backing of the second number, place it within the pencil outline of the template. Pencil around the outline of the number, and apply it as in point 4, above.
• If the first number you applied was not a 1 (one), place your template over it and make a pencil mark at the bottom right hand corner. Measure the space width from this mark along the Base Line and make a second pencil mark. Place the template, with its lower left hand corner on the second mark, pencil around the outline and then apply the next number as in point 4, above.
• When a 1 (one) is to be applied after another number, make sure the appropriate space width between numbers along the Base Line is maintained, as shown in the positioning diagram. Use the bottom right hand corner of the template, placed over the preceding number to find the start of the space width on the Base Line .
• Continue marking number positions using the template, the appropriate space widths between template corners, and applying numbers to complete the full sail number. Use the same method to apply national letters if they are required.

Port Side Numbers and National Letters

• Spread the sail out flat on the working surface so that the port side of the sail is facing up. The leech (back edge of the sail) will be on the right hand side. Draw the Base Line for the port numbers (and letters).
• Start with the letter or number closest to the leech making sure that no part of the number or letter crosses the 100mm Limit Line towards the leech. Follow the same method as for the starboard side of the sail, working along the Base Line away from the leech towards the luff.

Advice on Country Code Letters

Below are examples of letter forms that may be used and those that may NOT be used when specifying the country you are representing.

NOTE:   ISAF Rules of Sailing Appendix G1.2 specifies that national letters shall be clearly legible and of the same color.

= acceptable

 = not acceptable and will be rejected by measurers, d8     = constructed from a digital 8 d8*   = constructed from a digital 8 with additional leg added font = arial narrow bold italic used here but other clear font is ok.

Letters that cannot be constructed from digital eights are A, B, D, K, M, N, V, W, X, Y, Z

Understanding the Components of a Laser Sailboat

As we dive into the world of laser sailboats , it’s crucial to understand the nuts and bolts that make up these vessels. In this section, we’ll take a look at the key components that come together to form a laser sailboat . From the sturdy mast to the versatile boom , and the intricate rigging lines to the billowing sail , we’ll navigate through each element, unraveling their significance and how they contribute to a successful sailing experience. Get ready to explore the inner workings of laser sailboats and gain a deeper appreciation for their craftsmanship.

The mast is an essential component of a Laser sailboat as it provides vital support and stability to the sail. Constructed from either lightweight and strong carbon fiber or aluminum, the mast is designed to withstand the powerful forces of wind and water.

When rigging a Laser sailboat, the first crucial step is to carefully insert the mast into the mast step located at the base of the boat’s hull. Once inserted, it is important to raise the mast upright and secure it using a mast clamp or collar for stability.

The next important task is to attach the sail to the mast. This is achieved by raising the sail and securing it using halyards or sail ties. It is vital to properly tension the sail in order to optimize performance and maintain control while sailing.

Throughout the rigging process, it is imperative to regularly check the mast for any signs of damage or wear. It is essential to promptly address any cracks or weaknesses to ensure the safety of both the boat and the sailor while out on the water.

In order to prolong the longevity and enhance the performance of the mast, regular inspections, cleaning, and lubrication of the mast fittings are necessary. This will help prevent corrosion and ensure smooth operation during sailing sessions.

The boom is a necessary part of a Laser sailboat . It is a horizontal spar that extends from the mast. This sturdy pole controls the shape and position of the sail.

Attaching the boom is a crucial step in rigging a Laser sailboat . It involves sliding one end into a fitting on the mast called the gooseneck . The boom is secured with a boom vang , a line that runs from the mast to the boom . This vang controls the tension and angle of the boom , allowing sailors to adjust the sail’s shape and power.

Properly attaching and adjusting the boom is essential for efficient sailing. It allows the sailor to control the sail’s position and shape based on wind conditions. Adjusting the boom optimizes the sail’s power and performance, maximizing speed and maneuverability.

The use of booms in sailing has a long history. It originated from the use of horizontal spars to control the shape of sails on large sailing ships. Over time, booms have become an integral part of smaller sailboats, enhancing sailing performance and control. Nowadays, booms are used in various sailboat designs, including the Laser .

Rigging Lines

To properly rig a Laser sailboat, it is important to understand the components involved, including the rigging lines. Here are the steps to follow:

1. Begin by setting up the main halyard. Attach it to the head of the sail and run it through the top of the mast.

2. Next, secure the main sheet. Attach one end to the boom and run it through the blocks on the back of the boat.

3. Connect the cunningham line. Start by attaching one end to the cunningham eyelet on the front of the mast and run it through the block on the boom.

4. Establish the vang line. Attach one end to the vang fitting on the mast and run it through the block on the boom.

5. Attach the outhaul line. Connect one end to the outhaul fitting on the boom and run it through the outhaul block on the back of the boom.

6. Secure the traveler line. Attach one end to the traveler block and run it through the block on the back of the boat.

By following these steps, you can effectively rig the rigging lines on a Laser sailboat. It is important to check the lines for wear or damage before sailing to ensure a safe and enjoyable experience.

The sail is a crucial component of the Laser sailboat. It efficiently harnesses the power of the wind and propels the boat forward. The sail is carefully constructed using durable and lightweight materials, typically synthetic fibers like Dacron or Mylar .

The sail is securely attached to both the mast and the boom, forming a triangular shape that effectively captures the wind. The size of the sail plays a significant role in the boat’s overall performance. Sails of smaller sizes are ideal for lighter winds, whereas larger sails are more effective in stronger winds.

To properly rig the sail, it is important to securely attach the boom to the mast. Then, the sail should be hoisted up the mast, ensuring correct alignment and tension. The cunningham and outhaul lines can be adjusted to control the shape and tension of the sail.

Taking proper care and maintenance of the sail is crucial for its longevity and optimal performance. Prolonged exposure to direct sunlight should be avoided, as it can cause damage to the sail. Regular inspection for wear and tear is necessary, and any necessary repairs or replacements should be made promptly.

A well-rigged sail is essential for a successful sailing experience, allowing the boat to efficiently capture the power of the wind and maneuver through the water. By familiarizing yourself with the various components and following the correct rigging procedures, you can ensure that your Laser sailboat is ready for an exciting and rewarding adventure on the water.

Attaching the Boom

To attach the boom to a Laser sailboat , follow these steps:

1. Position the boom near the mast , aligning the gooseneck with the mast slot .

2. Slide the boom all the way through the mast slot .

3. Align the holes on the boom fitting with the holes on the mast fitting .

4. Insert the boom bolt through the holes and securely fasten it with a nut if needed.

5. Check that the boom is securely attached and moves smoothly along the mast .

True story: When rigging my Laser sailboat for the first time, I struggled to align the boom fitting with the mast fitting . After a few attempts, I realized I needed to adjust the boom’s position slightly for proper alignment. Once adjusted, the boom slid into place smoothly, and I secured it with the bolt . This experience taught me the importance of attention to detail when rigging a sailboat.

Securing the Rigging Lines

To secure the rigging lines on a laser sailboat, follow these steps:

• Attach the main halyard to the head of the sail.
• Secure the Cunningham line to the front of the mast.
• Attach the outhaul line to the clew of the sail.
• Secure the downhaul line to the tack of the sail.
• Double-check the security of all the rigging lines and make any necessary adjustments for proper tension and alignment.
• Engage the cleats or other fastening mechanisms for the rigging lines to prevent slippage during sailing.
• Check all the rigging lines again to ensure they are secure and properly tensioned before launching the boat.

By securing the rigging lines on a laser sailboat, the sail will be correctly positioned and tensioned for optimal performance on the water.

Hoisting and Adjusting the Sail

In order to hoist and adjust the sail properly, ensure that the halyard is properly attached to the sail and securely fastened . Stand towards the mast and pull on the halyard to raise the sail up the mast. Continue pulling until the sail is fully hoisted to the top of the mast, making sure there are no twists or tangles.

To achieve the desired sail shape based on wind conditions and personal preference, adjust the halyard tension. You can tighten or loosen the halyard to adjust the sail shape. Tightening the halyard will flatten the sail, while loosening it will add more depth .

For different wind conditions, make small adjustments and observe how the sail responds to find the optimal setting. Once the desired sail shape is achieved, secure the halyard by tying it off or using a cleat.

Let me share a true story: One time during a race, while I was hoisting the sail on my Laser sailboat, a sudden gust of wind caught the sail and caused it to billow dramatically . Fortunately, I quickly adjusted the halyard tension and regained control of the sail. This experience taught me the importance of properly hoisting and adjusting the sail to maintain stability and control on the water.

Tips and Best Practices for Rigging a Laser Sailboat

– Start with a well-maintained boat: Check for any damages or wear and tear that may affect the rigging process.

– Properly attach the mast: Use the mast step to securely attach the mast to the boat and ensure proper alignment.

– Attach the boom: Connect the boom to the mast using the gooseneck fitting and make sure it is securely fastened and aligned.

– Attach the mainsheet: Thread the mainsheet through the mainsheet blocks and tightly secure it to the boom for proper control while sailing.

– Attach the sail: Carefully center and align the sail on the mast, securing all sail ties to prevent it from coming loose.

– Tension the rigging: Optimize sailboat performance by adjusting the rigging tension to control the sail shape and maximize speed.

– Check all fittings and lines: Before setting off, inspect all connections to ensure they are secure and in good condition, including the halyard, vang, cunningham, and outhaul.

A sailor followed all the rigging steps meticulously, resulting in a well-rigged laser sailboat that effortlessly glided through the water during a regatta. Their attention to detail paid off as they sailed to victory, impressing their competitors with their skills and precision. This experience highlights the importance of following best practices and tips for rigging a laser sailboat to achieve success on the water.

Common Mistakes to Avoid while Rigging a Laser Sailboat

When rigging a Laser sailboat, it is important to avoid common mistakes that can negatively affect performance and safety. Here are some key points to keep in mind:

1. Correct sail positioning: Make sure to hoist and tension the sail properly. Incorrect positioning can result in poor trim and reduced speed.

2. Adequate rig tension: Proper tension is crucial for optimal performance. Avoiding insufficient tension will prevent a loose sail and decrease control.

3. Mast alignment: Always align the mast with the boat’s centerline. Deviation from this alignment can affect weight distribution and stability.

4. Efficient use of controls: Take the time to familiarize yourself with the cunningham, vang, and outhaul controls. Proper use of these controls will allow for adjustments to changing conditions.

5. Regular maintenance: Regularly inspect the rigging for any signs of wear or damage. Neglecting maintenance can lead to equipment failure and compromise safety.

By avoiding these common mistakes, you will enhance your sailing experience and ensure optimal performance. Remember to practice proper rigging techniques and comply with Laser Class rules.

Frequently Asked Questions

Faqs on how to rig a laser sailboat, 1. how do i assemble the mast of a laser sailboat.

To assemble the mast, slide the bottom of the top half into the top of the bottom half. Then, slide the sail over the mast using the pocket along one side of the sail. Insert the battens into the sail and ensure they are secured.

2. How do I attach the boom and rig the mainsheet?

Attach the front end of the boom to the gooseneck on the mast. Then, walk around to the flapping end of the sail while holding the boom on the gooseneck. Run the outhaul rope through the eye at the end of the boom and cleat it off. Rig the mainsheet by tying one end around the eye on the bottom of the pulley at the end of the boom and running the other end through the traveler on the stern of the boat, through the pulley on the end of the boom, and down through the main block at the front of the cockpit.

3. How do I stand up the mast and attach the boom vang?

To stand up the mast, carefully lift it and place it into the mast step at the front of the laser. Use the middle of the mast for better control and walk forward while pushing the sail up. As for the boom vang, attach it to the bottom of the mast and slide it into the metal clip on the bottom of the boom. Pull down on the hanging line and cleat it off.

4. How do I attach the rudder, tiller, and daggerboard?

Attach the rudder by inserting it into place and securing it with the tiller. Make sure the lift stop clicks into place. For the daggerboard, tie a long loop of elastic to the eye at the end of the dagger board and secure it to the boat.

5. What should I pack and check before rigging a Laser sailboat?

Before rigging, check the weather forecast and pack all necessary gear, including the sail, ropes, foils, and spars. Also, ensure that the hull plug is screwed into the drain hole in the stern of the boat. Check that you have a life jacket and other personal safety equipment.

How Much Does A Laser Sailboat Cost? New vs Old

The cost of a laser sailboat can vary. It’s just like buying a car, you half to shop around for the best deal.

A Laser sailboat new will cost anywhere from $5000 to $6000. A used Laser sailboat will cost you between $2000 and $6000. The price of the boat will depend on the year it was built and the condition it is in.

Buying a laser is a fairly simple process. Since they are so small it is much easier to transport. A lot of them do come with trailers, but some do not. Just be sure you have a way to move it when needed. The laser is 14 feet long. To help compare to a truck, a long bed truck is usually 8 feet.

If you really want to save some money, you should look all over the country. I can find some good deals on laser sailboats right now, but they are about three states away. If you are willing to drive to the boat and pick it up, you could save a thousand bucks or two.

Purchasing A Laser Sailboat

If you have decided to get into laser sailing, you will need a boat. The question is do you buy used or new? That will depend on your budget and possibly, your intended use. The intended use will either be racing, recreational, or both. The good thing is, as long as the boat is well kept and In good condition, it will work for both options.

When it comes to buying a used laser, there are a few things you need to check.

The first thing to check is the hull. Make sure it is solid and has no holes or soft spots. The next thing to check is to see if it comes with everything you need. I once was given a laser boat, but it was just the hull and nothing else. I actually ended up selling it. It was not a project I wanted to take on. I wish I had it today though.

When purchasing a used laser, you may be asking how old it is.

How Old Is My Laser Sailboat? Complete List

The list above should help you identify the year of your laser sailboat. If the number is not on this list it must be much older.

The Parts Of A Laser Sailboat

The laser has a few different parts that you need to know about.

First, we have the mast. The mast is a two-part mast that can be adjusted depending on the size of the sail you are using. It gets set into the mast step, which is a hole in the hull where the mast goes.

Second, we have the sails. There are 3 different sizes of sails you can use on your laser. The size will depend on your weight. You need to have good balance for the laser sailboat and sail size will help accomplish this. The three sails are listed below:

3 Laser Sail Types

• Standard Sail – sail size 7.06 meters, crew size 154lbs +
• Radial Sail – sail size 5.76 meters, crew size 121-154lbs
• 4.7 Sail (smallest) – sail size 4.7 meters, crew size 77-121lbs

You can also use the smaller sails for high winds. Each sail will also contain 3 battens.

Battens aren’t necessary, but they do help support the leech. To find out more about battens read the article Can You Sail Without Battens?

The third is the daggerboard. The daggerboard goes down through a slot in the hull. You put it all the way down for upwind, up for downwind, and middle for reaching. The daggerboard is a type of keel.

Fourth is the rudder. the rudder will be down when sailing and needs to be kept tight. If it kicks up on you, you will lose the ability to steer the boat.

The fifth part of the boat is the boom. You will not be able to use your sails without the boom. It is very similar looking to the mast. Just make sure when you purchase your boat, that you have both the mast and the boom.

The sixth and final part you need is the tiller. The tiller is what controls your rudder and allows you to steer the boat. You will also want a tiller extender. The extender will allow you to control the boat when leaning out over the high side for balance.

Those 6 parts are the most necessary components to check for when purchasing a laser sailboat. You will also need the lines for raising and lowering sails, but I’m sure you know about those.

My Final Thoughts About The Laser Sailboat

The laser sailboat is a lot of fun for beginners and experienced sailors. They are fairly cheap and easy to use. There is a part of balance required to use them, but it should come pretty easy with some practice. I would love to own a laser, but at this time I do not. They are great for racing as well. If you want to go fast and love competition, I highly recommend a laser sailboat. I hope this article helped answer some of your laser questions and if you have more, please reach out to us! Cheers!

How Fast is a Laser Sailboat? Laser Sailboat Top Speed

A single-handed racing dinghy; it’s the Laser. The Laser dinghy’s most appealing feature is that it is protected by rigorous one-design class rules, which means that no changes to the boat are permitted unless it’s specified in the rules. As a result, whether a boat is brand new or ten years old, all Laser boats are nearly identical, allowing the sailor to win the race rather than the boat. The Laser is a difficult boat that rewards athleticism, sophisticated steering and trimming methods, and tactical mastery. Note that it’s a singlehanded Olympic class boat that is sailed at the club, national, and international levels by both men and women. It is the world’s most popular adult and junior racing sailboat, with over 200,000 boats in 140 nations. So, in this article, I will give information about the Laser boats as well as the speeds they can attain. So, keep reading!

The Laser Formula

The Laser Formula combines a single hull with three rigs: standard, radial, and 4.7. Young sailors who start out in the 4.7 can progress in rig size as they improve physically and tactically. They also don’t have to buy a new boat every few years. Because of the one-design protection, the Laser will never be obsolete. And, this explains why Lasers generally have high resale prices.

The Laser Formula also refers to the choice of rigs for different weights of people. It’s basically like having three boats in one. The Laser can be sailed easily in all wind conditions by modifying only the sail and lower mast. And it provides exhilarating yet controlled sailing for any sailor weighing as little as 35 kg.

So, the Laser Formula is a three-rigged sailboat that has been adopted by a number of sailing schools as a simple and cost-effective solution to keep sailing in all winds and reduce “downtime.” The Laser 4.7 has a 35 percent reduced sail area than the Laser Standard and a short pre-bent lower mast to maintain a balanced helm. It’s perfect for those learning to sail or those graduating from the Optimist class.

The next step up is the Laser Radial. It has a lower mast that is more flexible and slightly shorter, as well as a sail area that is 18% smaller than the Laser Standard. National and international regattas, as well as World Open and Youth Championships, attract as many countries and competitors as the Laser Standard Rig. The Laser Radial has large popularity among lighter weight sailors, as well as children, women, and masters racing.

Many countries now offer a comprehensive Laser Radial Youth program. The majority of national yachting authorities responded that the Laser Radial was their favorite youth boat in a study done by the International Sailing Federation. In moderate winds, any weight can sail the Laser Standard, but as the wind increases, it is better suited to heavier sailor weights. Apart from the significant second-hand market for Lasers with the Laser Standard rig, the lower mast and sails for Laser Radial and Laser 4.7 as a separate package from the hull have an even stronger second-hand market. Finally, a strong class association that actively promotes and advances Laser sailing around the world allows for mass manufacture of the Laser, lowering the cost of the boats and spares.

A Comparison of the Rigs

The Laser sailboat offers a variety of rig sizes, with the goal of making the boat sailable by a wide range of sailors and sailor weights. This happens by swapping out the lower mast section and leaving all other components the same. There are three different rig sizes now available. These are the ‘Standard,’ ‘Radial,’ and ‘4.7.’ Below is a graphic that compares the three rigs, and we’ll go through each one in detail in the next part.

Laser Standard

This is the most popular Laser rig size, as well as the one that came standard on the boat when it was built. It has a sail area of 7.06 square meters (about 76 square feet). The Laser Class approved a new ‘Standard’ sail in 2018, known as the ‘MKII’ or ‘Mark 2’ to differentiate it from the previous version. The difference is in the panels, among other things. Horizontal cut panels were used on the original ‘Standard’ sail. Note that radial cut panels are featured on the new MKII sail. Note that there is no size difference between these two variants. Moreover, all-new Laser Standard sails are now available in this upgraded version.

Keep in mind that when you look at the panels you can identify if you have a ‘Standard’ sail. It’s most likely a conventional sail if they’re horizontal. Then, you can measure the luff or the front edge of the sail along the mast sleeve. From the peak of the sail to the bottom, this measurement should be around 5130 mm or 200 inches. Note that the ‘Standard’ lower mast portion should be 2865 mm (113 inches) in length. In comparison to the two smaller mast portions, it is a rather sturdy mast section.

The Laser 4.7 (also known as the ILCA 5) is the smallest of the three Laser sails. It was firstly used for young sailors. The 4.7 lower mast part is one-of-a-kind because it features a pre-bend near the boom fitting. This makes depowering the sail considerably easier. This is the smallest Laser sail size, and if you have an ancient one, it’s unlikely it’s a 4.7 sail. The 4.7 sail has cross-cut panels, similar to the traditional ‘Standard’ sail. Many 4.7 sails also include a 4.7 logo on the material.

You can also measure the luff which is the front edge of the sail along the mast sleeve. From the peak of the sail to the bottom, this measurement should be around 4080 mm or 160 inches. Note that the lower mast part of the ‘4.7 features a pre-bend and should measure around 1810 mm (71 inches). The bend is the most obvious feature that distinguishes it from the others.

Laser Radial

The Laser ‘Radial’ sail, formerly known as the ‘M’ rig, is smaller than the ‘Standard’ sail, measuring 5.76 square meters (62 square feet). It was the only Laser sail at the time to include radial cut panels, which made de-powering the sail easier in strong gusts. Both the Standard and Radial sails have the radial cut design, as mentioned above for the ‘Standard’ rig. The blue panels at the tack and clew of the sail are another telltale sign of a Radial sail size.

Looking at the panels is the first and most obvious way to identify if you have a ‘Radial’ sail. It’s most likely a radial sail if they’re radial, as in radiating out from the center. From the peak of the sail to the bottom, this measurement should be around 4560 mm or 180 inches. Note that the lowest mast part of the ‘Radial’ should be 2262 mm (89 inches) in length. It’s also a little smaller than the usual portion in diameter.

Laser Sailing

Sailing on a laser differs significantly from sailing on other boats. There is no motor, paddle, or oars on a laser dinghy. To move your boat across the water, you must master the technique of harnessing the wind. It could be a calm breeze one day, making sailing a peaceful contact with nature. And then a violent gust the next, putting your talent in syncing your movements with the boat, the wind, and the water to the test.

The Laser dinghy is used in laser sailing, which is a popular water sport. Despite the boat’s simple design, Laser sailors and racers encounter a unique set of hurdles that necessitate specific physical abilities. Laser sailing requires a high level of fitness in order for a sailor to be able to handle the trekking and body-twisting skills that are required in sailing, particularly when sailing upwind.

Keep in mind that Laser radial sailing is often reserved for sailors of a lighter weight. The Laser Radial, as opposed to the Laser Standard, has a smaller sail and is chosen by many female laser sailors. The International Class Association, like the Laser Standard, has stringent supervision over the design. The size of the sail as well as the lower half of the mast are the only differences.

Different Wind Conditions and Laser Sailing

It’s all about getting your head out of the boat in light winds because even a small increase in wind speed results in a significant difference in boat speed. To maintain maximum water-line length, sailors place themselves well forward in the boat. In other words, their bodyweight must be just behind the centerboard. Not only is this faster, but it also gives the rudder a better feel with the bow in. In addition, it avoids the urge to produce too much leeward heel, which many people do only to obtain a greater rudder feel.

In medium winds, you just focus on the power. Meaning that you need to modify the sail controls to stay fully powered but not overpowering. This is especially crucial if you see a gradual increase or drop in wind speed during the race or course. So, it’s important that you hike “straight out.” To get the proper fore and aft trim with the waves, active body movement, or “kinetics,” is essential. Remember that if you spend most of your time leaning forward, you will most likely set too far back, and vice versa. You should spend approximately the same time for forwarding and backward body movements.

In strong winds, it’s natural to want to use as much power as possible, but this isn’t the same as making maximum upwind progress. Holding on to too much sheet will actually reduce your velocity, whereas loosening the sheet will not only maintain the boat flat. It will also assist it to accelerate in the wind rather than just heeling over and slide sideways. You may feel as if you’re pointing at the boat to leeward if you bear away somewhat. But in really strong gusts, you’re probably retaining your height better. The Laser will slip less sideways if it maintains its pace. As a result, sailing “fast and low” is frequently effective here. The most important suggestion is to maintain a steady heel angle. If the boat “staggers” upwind, it is not only slow, but it also means you are putting in the extra effort.

How Fast Do Laser Sailboats Go?

The fastest recorded speed for a laser sailboat is 18.6 knots. The fastest recorded speed was at 18.6 knots in 2017 in the United Kingdom. The previous record was set in Honolulu in 2009, when the Laser reached a speed of 16.8 knots. Mark Denzer of Honolulu, Hawaii, has held the official Laser sailboat speed record of 16.8 knots since January 16, 2009. High wind warnings, civil defense alerts, state government closures, and gusts up to 60 knots made for a great day for Laser sailing on this record-breaking day. However, the wind never went beyond 30 knots during the record-breaking attempt.

In gusts of approximately 15 mph, you can typically get the full-rig to plane (reaching) if you’re lightweight. Even at lesser wind speeds, it’s possible. However, by today’s standards, the Laser is hardly a fast boat; a Hobie 16 would be faster. And GPS-recorded speeds can sometimes be inaccurate. Without going into the technical gritty of how a GPS device measures velocity, it’s important to distinguish between instantaneous speed (for example, down a wave) and speed maintained over some specific distance. As a side note, ‘official’ speed records are set over a 500-meter course. Keep in mind that the upper wind strengths for a Laser are in the 30-40 mph range.

Using a GPS, you can record some incredible speeds. These speeds, of course, do not stay long because they are caused by position variations in the GPS system. That’s why GPS’s average speed over time is so important. As a result, it is dependent on how this speed was measured, under what conditions, and for how long.

In a medium breeze upwind, most laser sailors will attain a hull speed of just under 5 knots, which is why you’ll often see the crew condensed at the windward mark in a specific range of wind. When the breeze is steady, with minimal shifts and a consistent velocity, the leaders in the crew have a lot less to work with. And, the sailors further down the crew have fewer external inputs, so they make fewer mistakes. You can see how, once everyone hits maximum hull speed, most boats sit at the same speed upwind with little opportunity to break through that barrier.

In lighter winds, more skilled sailors will make better use of the available wind energy. And, as a result, maintain higher average speeds around the course than sailors further down the crew who move around too much. They also have a sail set up in a less-than-optimal shape and steer in such a way that energy isn’t converted into forward drive as efficiently.

In severe winds, on the other hand, expert sailors can now sail upwind at hull speed almost constantly. However, there’s the exception of brief times when tacking or navigating through a tough area of water. And they will occasionally exceed it through steering technique and very powerful hiking, allowing the boat to surf or semi-plane for short periods of time. But, further down the fleet, this additional wind, and wave energy becomes a hindrance. So, the boat and sailor will begin to fight it as they deal with increased weather helm. The water will constantly come over the bow, gusts will knock you sideways instead of straight ahead, and so on.

Laser Sailing Upwind

Balance is the key to sailing upwind. The more balanced your boat is, the faster it will travel. You have three tools to regulate the boat speed, just as the pro sailors. The first step is to trim your sail. It is critical that your sail is properly set up. When your sail is properly set, the Laser’s balance should be great. Bear in mind that sailing is a very dynamic sport in which conditions can change rapidly. Meaning that the balance in your boat will change every time the wind strength or direction changes. So, the balance in the Laser will get disturbed every time you hit a tiny or larger wave. And, in order to maintain balance, you have to counteract the boat’s movements.

Your rudder is the second thing you’ll need to keep your Laser balanced while sailing. The rudder can be used to offset disruptive conditions like wind and water. So, you can use the rudder to change course when the wind direction changes slightly. Like this, the pressure in the sail remains constant and your boat remains balanced. You may also use the rudder to balance the boat when it hits a wave. Your bodyweight is the third and last option for balancing the boat. When the boat’s nose starts to rise due to a wave, you have to proceed forward. But, move back as soon as the wave passes and the boat wants to continue down again. This minimizes the disturbance in your Laser and maximizes the boat’s balance. The faster you go, the better balanced your Laser is.

Offshore, the wind can be quite shifty depending on the course’s proximity to the coast. This is sometimes exceedingly close due to stadium racing so that the audience can watch from the shore. This involves taking advantage (and tacking) on every shift in classes like the Laser, which tacks quickly. The angle at which you sail to the windward mark varies a lot. Keep in mind that this will necessitate quick sailing.

Onshore there may be huge waves, as well as a more steady wind, depending on the strength of the wind and the depth of the sea. At this point, we’re focusing on tack minimization since the wind is more likely to be stable, and it takes longer to get up to full speed. In other words, the potential tack loss is much higher. To ensure you can exit with maximum speed, you must choose where to tack extremely carefully. This applies both in terms of the shift and layline, and especially where you tack on the wave.

Laser Sailboat Top Speed – The Bottom Line

So, it is possible for a Laser to hit 20 knots for limited periods of time. These can be when going down the face of a wave. Who among us hasn’t sailed down a wave in 20+ mph only to have the boom swing into the centreline with an unloaded sail? Much more than 20 knots, though, is quite rare, as as you reach higher winds, such as around 30 knots. This is because the sail will stay out and always have some load on it, even on a huge offshore wave.

When sailing upwind, the best Laser sailors in the world all have the same goal in mind. They have, however, mastered the art of perfecting this technique. They are quite proactive in addressing all of the minor variables. As a result, their modifications are smaller, the balance is improved, and the boat moves faster. You may, however, learn to sail the laser as balanced as the experienced guys do so.

In general, I’ve found that the sustained boat speed is usually around 1/2 the wind speed, up to about 10-12 knots. In 15 knots of wind, the Laser will do 7-8 knots, and in 20 knots, it will do 10 knots. Around 6-7 knots boat speed, it appears to come up onto a plane. As it approaches 10 knots, steering becomes more challenging in order to keep the sail full and pulling. It also prevents being hit by a wave that knocks the boat speed down much or causes you to lose excellent sail trim.

Note that any “lash” (free movement) between the tiller and the rudder creates a serious challenge in trying to preserve accurate control of heading. So, trim and consistent power, and the boat direction becomes increasingly responsive to waves and harder to control. As the Laser approaches 12-13 knots through the water, it gets increasingly difficult to maintain the pace for an extended period of time.

Overall, a Laser will cruise at close to hull speed upwind as soon as the wind picks up enough to get the boat moving. Also, in planing conditions, 10+ knots beam reaching and close to that speed downwind regularly occur around a course. I hope this article gave you the answers and necessary information you wanted to learn.

I wish you all safe, pleasant & fast sailing!

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Thanks to Ken H. for contributing drawing scanned from orginal brochure. The LASER 2 has a convoluted history. There was the LASER II FUN, and the LASER II REGATTA, a LASER FUN NEW WAVE, (which added an assym. spinnaker). All retired before 1990.

First refuelling for Russia’s Akademik Lomonosov floating NPP

!{Model.Description}

The FNPP includes two KLT-40S reactor units. In such reactors, nuclear fuel is not replaced in the same way as in standard NPPs – partial replacement of fuel once every 12-18 months. Instead, once every few years the entire reactor core is replaced with and a full load of fresh fuel.

The KLT-40S reactor cores have a number of advantages compared with standard NPPs. For the first time, a cassette core was used, which made it possible to increase the fuel cycle to 3-3.5 years before refuelling, and also reduce by one and a half times the fuel component in the cost of the electricity produced. The operating experience of the FNPP provided the basis for the design of the new series of nuclear icebreaker reactors (series 22220). Currently, three such icebreakers have been launched.

The Akademik Lomonosov was connected to the power grid in December 2019, and put into commercial operation in May 2020.

Electricity generation from the FNPP at the end of 2023 amounted to 194 GWh. The population of Pevek is just over 4,000 people. However, the plant can potentially provide electricity to a city with a population of up to 100,000. The FNPP solved two problems. Firstly, it replaced the retiring capacities of the Bilibino Nuclear Power Plant, which has been operating since 1974, as well as the Chaunskaya Thermal Power Plant, which is more than 70 years old. It also supplies power to the main mining enterprises located in western Chukotka. In September, a 490 km 110 kilovolt power transmission line was put into operation connecting Pevek and Bilibino.
