This is Windex

The WINDEX was first designed and brought to market in 1964 by RADAB (Research And Development AB), a small company run by three young engineers who also happened to be close friends, Sven-Olof Ridder, Harald Undén and Lars Bergström.

The original WINDEX design by Sven-Olof Ridder, an aeronautical engineer who is recognized worldwide for his design skills, was made of aluminum. The design was successful and soon became popular with Swedish sailors. However, the international breakthrough came in 1972 when a large investment in plastic tooling was made, which allowed for large quantity production at a lower cost. One of the design criteria at the time was that the WINDEX should be “as sensitive in light air as cigarette smoke”. The solution was a plastic wind vane with low weight and a large fin mounted on a Sapphire jewel bearing like a compass needle.

This design, which incorporates the now famous Sapphire jewel suspension has remained unchanged and extremely popular with sailors through the decades.

RADAB and its founders have also been involved with the development of several other successful engineering projects, among them are the Windex 92 Family Cruiser and the Windex 1200 C.

How to Read Wind Indicators for Sailing: The Complete Guide

Sailing is a thrilling and challenging sport that requires a great deal of skill and knowledge. One of the most important skills for any sailor to learn is how to read wind indicators. Wind indicators, also known as wind vanes or telltales, provide crucial information about wind direction and speed, which is essential for making tactical decisions while sailing.

Table of Contents

Understanding Wind Direction

When it comes to sailing, understanding wind direction is crucial. The direction of the wind can affect the speed and course of a sailboat. Here are some key points to keep in mind when reading wind direction:

• Wind direction is measured in degrees clockwise from true north. For example, if the wind is coming from the north, it is 0 degrees. If it is coming from the east, it is 90 degrees.
• Wind direction can be affected by local topography, such as hills or buildings. This is known as wind shear.
• Wind direction can also be affected by the sailboat’s position relative to the wind. For example, if the sailboat is sailing directly into the wind, the wind will appear to be coming from the front of the boat. This is known as the “no-go zone.”
• One way to determine wind direction is to look at the direction of the waves. Wind will cause waves to form in a certain direction, which can indicate the direction of the wind.
• Another way to determine wind direction is to use a wind indicator, such as a wind vane or wind sock. These indicators will show the direction of the wind relative to the sailboat.

Types of Wind Indicators

Wind indicators are instruments that help sailors determine the direction and strength of the wind. There are various types of wind indicators available, each with its own advantages and disadvantages.

The Windex is a popular wind indicator that many sailors mount on the masthead of their boats. It is a simple device that consists of a vane or an arrow that points in the direction of the wind. The Windex is easy to install, lightweight, and affordable. It is also easy to read, even from a distance. However, the Windex is not very accurate in light winds, and it can be affected by the boat’s motion.

Telltales are small strips of fabric or yarn that are attached to the sail. They help sailors determine the direction and strength of the wind by showing the flow of air over the sail. When the sail is properly trimmed, the telltales should be streaming back smoothly. If they are fluttering or standing still, it means that the sail needs to be adjusted. Telltales are inexpensive, easy to install, and provide real-time feedback on sail trim. However, they can be difficult to see in low light conditions, and they can be affected by the boat’s motion.

Masthead Anemometer

A masthead anemometer is a more advanced wind indicator that measures the speed and direction of the wind at the top of the mast. It consists of a vane that points into the wind and a set of cups that spin in the wind. The speed and direction of the cups are measured by sensors, and the data is transmitted to a display unit in the cockpit. Masthead anemometers are very accurate, even in light winds, and they provide real-time feedback on wind speed and direction. However, they are expensive, difficult to install, and require regular maintenance.

Handheld Anemometer

A handheld anemometer is a portable wind indicator that measures the speed and direction of the wind at the location of the sailor. It consists of a small vane and a set of cups that spin in the wind. The speed and direction of the cups are measured by sensors, and the data is displayed on a small screen. Handheld anemometers are easy to use, affordable, and provide accurate readings. However, they require the sailor to hold the device steady, which can be difficult in rough seas, and they can be affected by the sailor’s body heat.

How to Read a Masthead Wind Indicator

A masthead wind indicator, also known as a Windex, is a device that is mounted on the masthead of a sailboat to show the direction of the wind. It is a simple and effective tool that helps sailors to adjust their sails and steer their boat in the right direction. Here are some tips on how to read a masthead wind indicator:

Observing the Vane

The vane of a masthead wind indicator is the part that moves with the wind. It is usually made of lightweight materials like plastic or aluminum, and it is designed to be sensitive to even the slightest breeze. When observing the vane, it is important to note the following:

• The direction of the vane: The vane will point in the direction that the wind is coming from. This is useful information for sailors who need to adjust their sails to take advantage of the wind.
• The angle of the vane: The angle of the vane relative to the boat’s centerline will tell you how much the boat is being pushed sideways by the wind. If the vane is pointing directly forward, the boat is sailing straight into the wind. If the vane is pointing to the side, the boat is being pushed sideways by the wind.

Interpreting the Tails

The tails of a masthead wind indicator are small pieces of fabric or plastic that are attached to the vane. They are used to show the relative strength of the wind. When interpreting the tails, it is important to note the following:

• The number of tails: Most masthead wind indicators have two or three tails. Two tails indicate light winds, while three tails indicate stronger winds.
• The position of the tails: The position of the tails relative to the vane will tell you the angle of the wind. If the tails are pointing straight back, the wind is coming from directly behind the boat. If the tails are pointing to the side, the wind is coming from the side of the boat.

By observing the vane and interpreting the tails, sailors can get a clear picture of the wind conditions and adjust their sails accordingly. With practice, reading a masthead wind indicator will become second nature, and sailors will be able to make quick adjustments to their sails without even thinking about it.

How to Read a Handheld Anemometer

When sailing, it is crucial to have an accurate reading of the wind speed and direction. Handheld anemometers are a great tool for this purpose. Here are the steps to follow to read a handheld anemometer:

Reading the Wind Speed

The wind speed is typically displayed in knots, miles per hour (mph), or meters per second (m/s). To read the wind speed on a handheld anemometer, follow these steps:

• Turn on the anemometer and wait for it to calibrate.
• Hold the anemometer up in the air, away from your body, at arm’s length.
• Point the anemometer directly into the wind.
• Read the wind speed displayed on the screen.

Determining the Wind Direction

The wind direction is typically displayed in degrees or cardinal directions (e.g., N, NE, E, etc.). To determine the wind direction on a handheld anemometer, follow these steps:

• Look at the display and note the wind direction.

Some handheld anemometers also have a wind vane or arrow that points in the direction of the wind. This can be helpful for quickly determining the wind direction without having to read the display.

How to Read a Windex Wind Indicator

Interpreting the reference arms.

The Windex wind indicator consists of a vane that rotates around a vertical axis and two reference arms that extend horizontally from the vane. The reference arms are designed to provide a visual reference point for the direction of the wind relative to the heading of the boat.

To interpret the reference arms, imagine them as the arms of a clock. The arm that is pointing to the left of the boat is the 9 o’clock arm, and the arm that is pointing to the right of the boat is the 3 o’clock arm. If the wind is coming from the direction of the 9 o’clock arm, it means that the wind is coming from the port side of the boat. If the wind is coming from the direction of the 3 o’clock arm, it means that the wind is coming from the starboard side of the boat.

Reading the Wind Direction

To read the wind direction using the Windex wind indicator, you need to combine the information provided by the reference arms with your knowledge of the boat’s heading.

If the boat is heading directly into the wind, the vane of the Windex wind indicator will be pointing straight up, and the reference arms will be horizontal. In this position, the 9 o’clock arm will be pointing to the port side of the boat, and the 3 o’clock arm will be pointing to the starboard side of the boat.

If the boat is on a port tack, the wind will be coming from the starboard side of the boat. In this case, the vane of the Windex wind indicator will be pointing to the port side of the boat, and the 9 o’clock arm will be pointing down towards the water. The 3 o’clock arm will be pointing up towards the sky.

If the boat is on a starboard tack, the wind will be coming from the port side of the boat. In this case, the vane of the Windex wind indicator will be pointing to the starboard side of the boat, and the 3 o’clock arm will be pointing down towards the water. The 9 o’clock arm will be pointing up towards the sky.

By combining the information provided by the reference arms and your knowledge of the boat’s heading, you can accurately read the wind direction using the Windex wind indicator.

Using Wind Indicators for Sailing Strategies

Understanding how to read wind indicators is crucial for any sailor who wants to improve their performance on the water. In this section, we will explore how to use wind indicators to optimize sail trim and choose the best course.

Optimizing Sail Trim

Sail trim is the art of adjusting the sails to achieve the most efficient and effective use of the wind. Wind indicators provide valuable information about the direction and strength of the wind, which can help sailors to optimize their sail trim. Here are some tips for using wind indicators to optimize sail trim:

• Keep a close eye on your wind indicator to detect changes in wind direction or strength.
• Adjust your sails accordingly to maintain the optimal sail shape and angle to the wind.
• Use the telltales on your sails to help you determine whether your sail trim is correct.
• Experiment with different sail trim settings to find the one that works best for the current wind conditions.

Choosing the Best Course

Choosing the best course is essential for reaching your destination as quickly and efficiently as possible. Wind indicators can help you to choose the best course by providing information about wind direction and strength. Here are some tips for using wind indicators to choose the best course:

• Look for areas of the water where the wind is stronger or more consistent.
• Use your wind indicator to determine the optimal angle to the wind for your boat.
• Adjust your course accordingly to take advantage of the wind direction and strength.
• Keep an eye on your wind indicator to detect any changes in wind direction or strength that may require you to adjust your course.

Maintaining Your Wind Indicators

Maintaining your wind indicators is crucial to ensure accurate readings and reliable performance. Here are some tips to keep your wind indicators in top shape:

1. Regular cleaning

Wind indicators can accumulate dirt, dust, and grime over time, which can affect their accuracy. Regular cleaning with a soft cloth and mild detergent can help remove any buildup and keep the indicators functioning properly.

2. Lubrication

Wind indicators often have moving parts that require lubrication to operate smoothly. Applying a small amount of silicone or Teflon lubricant to the moving parts can help reduce friction and prolong the life of the indicators.

3. Check for damage

Regularly inspect your wind indicators for any signs of damage, such as cracks, chips, or bent parts. Any damage can affect the accuracy of the readings and compromise the safety of your sailboat. If you notice any damage, replace the indicators immediately.

4. Calibration

Wind indicators can drift out of calibration over time, especially if they are exposed to extreme weather conditions. Regularly calibrating your indicators can help ensure accurate readings and prevent any mishaps on the water.

Proper storage is essential to keep your wind indicators in good condition. When not in use, store them in a dry, cool place away from direct sunlight and extreme temperatures. This will help prevent any damage or deterioration.

In conclusion, reading wind indicators is a crucial skill for any sailor, and with the right tools and techniques, it can be mastered. The key is to understand the different types of wind indicators available and how to interpret the data they provide.

Should You Use a Masthead Wind Indicator?

On a run with light and shifty wind, a masthead wind indicator is essential. The telltales on the shrouds are too affected by the sails to tell you what’s going on. Sailing Anarchy Forum

I do not like them because they really help your competition more than you. Sailing Anarchy Forum

Our coach, Dave Ullman, insisted that we get one and use it. Roble-Shea Sailing

A masthead wind indicator, sometimes called a masthead fly or a Windex (brand name), is a wind vane mounted at the top of the mast. Like shroud telltales, it tells you the direction of the apparent wind, which is a crucial cue for many aspects of sailing. See our post Ten Ways to Use Shroud Telltales for all the ways you can use shroud telltales (or a wind vane).

If you have shroud telltales, should you also use a masthead wind indicator? Sailors’ opinions vary, and a recent walk through the local boat park showed about 60% of boats with them (much higher % for the Flying Scots). Here we list the pros and cons.

Masthead wind indicator – Pros

#1. more precise than shroud telltales downwind.

When sailing downwind, a wind vane is a more precise indicator of apparent wind direction than shroud telltales, which are affected by flow off the sails. To see this, try a boat that has a wind vane. Sail downwind and adjust your heading so the wind vane points directly along the fore and aft axis of the mast. This indicates you are sailing dead downwind. At this heading, the difference in angle between shroud telltales and a wind vane can be as much as ten degrees. Knowing this allows you to sail dead downwind in breeze and thus sail less distance.

#2. Less Bouncy than Shroud Telltales

Being rigid, center mounted, and slightly heavier, a wind vane bounces around less than shroud telltales. In some cases, discussed below, it’s worth looking up to take advantage of this “noise reduction.”

#3. Better than Shroud Telltales for Some Situations

Attack and defend downwind.

It’s easier to use the wind vane here, due to its accuracy, stability, and unobstructed view. To attack, point the tail of the wind vane at competitors ahead. Defend by repositioning when the arrowhead of the wind vane is pointing at competitors behind you.

Identify layline downwind

The fastest way to the leeward mark is to keep sailing your best VMG angle until you reach the layline, then gybe and sail the same VMG angle to the mark. How do you identify the layline? Again the accuracy and unobstructed view make the wind vane more useful in this case. You reach the layline when the tail of your wind vane points to the leeward mark.

Identify true wind direction when sailing downwind

If you use a compass, you have to know the numbers. We all know how to identify the true wind direction by luffing head to wind. The accuracy of the wind vane allows you find the true wind direction when sailing downwind. Sail dead downwind, with the wind indicator lined up with the fore and aft axis. Check your compass heading and add or subtract 180 degrees to find the true wind direction.

This helps keep tabs on the “numbers” during the pre-race routine or on a downwind leg when you suspect the wind has shifted permanently.  

Identify wind shear to aid sail trim

In very light air (no ripples), the wind true direction at the top of the mast may be different than near the bottom. This is important for upwind sail trim. Check your wind vane against the shroud telltales. If there’s shear or gradient, adjust your sail trim and twist as necessary. For more, see our post Wind Shear and Gradient Effects on Trim & Strategy.

Masthead wind indicator – Cons

#1. one more item to distract your focus.

Distractions take away your focus from the really important stuff, and many top sailors try to keep things simple. Wind vanes are another bright, shiny object to distract you, and worse, you must look way up to see them. Shroud telltales are in your line of sight and give you the same information. You can learn to compensate for their inaccuracies downwind.

#2. May give your competitor an advantage

Your masthead wind indicator is useful for competitors. They don’t need one – all they have to do is look at your indicator to determine if they are in your bad air or vice versa.

The Verdict?

Do the pros outweigh the cons? Your editor is always tempted to go for more indicators (shroud telltales, sail telltales, marks on control lines, etc.), but that approach has added lots of distractions and thus has not always served him well. Therefore, we decline to make a recommendation, except to say that used judiciously, we have found them helpful in the situations discussed above.

What Is A Sailboat Wind Direction Indicator?

Wind direction indicators, also known as wind tells, are devices or visual cues used by sailors to determine the direction and strength of the wind while out on the water. They provide valuable information for sail trim, tacking , boat handling, and overall navigation.  

Wind direction indicators come in various forms, and their purpose is to show the relative wind direction and sometimes wind speed. Here are some common types of wind direction indicators:  

Wind Vane :  A wind vane is a physical device that is mounted on top of the mast or another elevated location on the boat. It typically consists of a small arrow or fin that points into the wind. The boat's crew can visually observe the wind vane to determine wind direction by noting the direction in which the vane is pointing.  WindTrak  is a popular type of wind vane that consists of a lightweight vertical spar or pole with an arrow-shaped indicator at the top. It is designed to pivot freely and align itself with the wind. The WindTrak is mounted on top of the mast, making it easily visible to the crew.   

Windsock : A windsock is a fabric tube open at both ends. It is commonly found in marinas, on docks, or onshore near water bodies. The windsock's shape and movement provide an indication of wind direction and sometimes wind speed. Sailors can observe the windsock from a distance to assess the prevailing wind conditions.  

Ribbon or Streamers : Sailors sometimes attach lightweight ribbons or streamers to the shrouds, stays, or other parts of the rigging. These fluttering indicators can help provide a visual reference of the wind direction and intensity.  

Telltale Streamers : Telltales (such as Davis Instruments' Air-Flow Tels ) are small strips of fabric or lightweight material attached to the sails or rigging. They are strategically placed to indicate the airflow over the sail surface. By observing the movement of telltales, sailors can fine-tune their sail trim to optimize performance based on wind direction.  

Wind direction indicators are essential tools for sailors as they provide real-time information about the wind, helping them make informed decisions about sail adjustments, boat heading, tacking and overall strategy. By interpreting the information provided by wind direction indicators, sailors can harness the wind effectively and sail their boats more efficiently.

Deck-level Wind Vanes

Not just for small boats, these sensors put the fun back in shifty winds.

There are two primary wind indicators on a sailboat. First, we watch the sails. Sailing to windward we watch the jib for luffing and for flow on telltales.

On the main we watch for backwinding near the luff and for good flow on the leach ribbons. Off the wind we are more likely to watch the masthead fly, leading to an epic crick in the neck. More importantly, when sailing in a real breeze we like to keep our eyes near to the water, watching for other boats, the dip of the bow when pressed hard, and scanning for approaching gusts. Theres no time for more than a glance at the masthead. Ribbons on the shrouds help, but often they are too strongly influenced by dodgers and the sails themselves.

Single sail boats, such as Lasers and Optimus dinghies often clamp wind indicators on the forward side of the mast (see Practical Sailor, January 2018, Top Notch Wind Indicators ). Without a jib to interfere with windflow or to luff at every wind shift (thus serving as a wind vane), they give a real-time estimate of wind direction. Thirty years ago Frye developed the habit of watching a Davis Telo-cat indicator that hung suspended under the forestay bridle of his beach catamaran. There it was safe from sheets and sails and directly in sight as he watched the lee bow for signs of submarining, one of the greatest concerns of a beach cat sailor on a fast reach.

As he moved on to larger catamarans, he always found a place to mount the indicator on one of the bows. On his Stiletto 27, the conventional masthead flies mounted at the end of the bow worked fine. That was because, unlike many monohulls or other catamarans, the bows on the Stilletto are far outboard and extend three feet forward of the forestay, where they are relatively undisturbed by air flow.

It was a fast boat and the spinnaker was jibed inside (the sheets passed between the tack and the forestay) like a jib. As is the case with most performance cats, the boat moved so fast off the wind that the apparent wind was rarely if ever dead astern. Instead, the fastest course to steer in terms of velocity made good (VMG) often involved tacking downwind.

When he moved up to a cruising catamaran (PDQ 32), he developed an unbreakable wind indicator ( PS January 2018 ) that could withstand a regular flogging from spinnaker sheets. With his current trimaran (Corsair F-24) he has settled on a pair of wind indicators, port and starboard, since the deck-sweeping genoa blocks the view of the indicator on the off tack. This dual arrangement also ensures at least one of the flies is working in relatively clean air, undisturbed by the jib. On many boats these flies would be vulnerable to sheets during tacking, but in the case of the Corsair, they are protected from reacher and spinnaker sheets by the up-haul used to raise and lower the hinged bowsprit. As the sheets cross the bow, the up-haul keeps them clear of the flies.

Are these sensitive sensors affected by air flow over the jib? Certainly, but they are still extremely useful for adjusting to gusts and shifts. The mounting arm holds them out in front of the jibs luff, and by mounting them low on the bow rail, they escape most of the disturbed air. Even when the jib is close hauled, the distance between the fly and the sail on Fryes boat is at least two feet. On many cruising boats they can be mounted well below the jibs luff, allowing even greater clearance.

Observations

The primary function of these bow vanes is not fine-tuning or fine steering adjustments. These are made based on sail-mounted telltales and the look of the sails themselves. Their true value is showing gross changes in wind direction. As you pass through a tack or jibe, what is the approximate wind angle?

A leeward wind shift has stalled the sails, but how big an adjustment is ideal? You’ve just born away in a strong gust to stall the sails, but how far aft has the apparent wind moved?

Sure, you could glance at the masthead, but when things are happening fast, thats not where your eyes should be. When bearing off you should be watching the bow. When attacking or jibing at speed, the movement of the headsail across the foredeck, the motion of the boom, and the position of other boats are more important than looking up.

Just as importantly, new crew and beginning sailors love them. When anchoring or hoisting sails they don’t need to split their attention; Just keep that vane pointed forward. When sailing they avoid disorientation by looking in too many directions. Remember teaching your kid to drive and watching in horror as the car began to turn every time they turned their head to check a blind spot?

Other than preventing them from fouling with ropes, the greatest challenge can be reading them. It’s easy to judge the angle of a masthead fly when looking up, and bow flies are easy to read on a dinghy or beach cat because they are close. But when they are 20 feet away and viewed from the same level, judging the exact angle is difficult. Indicator arms help.

Deck-level Windvane Options

Weve tried several different brands and models and found something of merit in each of them. Our main criteria was durability, but we did not discern a great difference. All of the vanes are vulnerable to a hard wack, so in the end, the best vane for you will be the one that fits your installation needs.

DIY unbreakable

The do-it-yourself yarn indicator that we featured in January 2018 is perfect for locations where a sheet or sail may find the indicator. It bends rather than breaks. On the other hand, the yarn is sometimes plastered down by rain or spray, sometimes tangles, and the direction can be hard to read.

Bottom line: This is the Best Choice if everything else breaks, but otherwise inferior.

Sailsteady Indicator

Designed by a Laser sailor, the springy Sailsteady is the only vane sensor weve seen that can withstand the abuse of slatting sails and dragging sheets.

We mounted it on the deck of our Javelin and found that a jib will hang up on the vane in light airs, but if theres a good breeze, the vane flops down, lets the line or jib pass, and springs back into action undamaged. It is most useful on small one-designs that have clear foredecks.

Bottom line: Made in the United Kingdom, the Sailsteady offers an option for small boat sailors concerned about deck-sweeping jibs. It comes with one extra vane.

Davis Black Max

Based on the very successful Telo-cat, this black and yellow indicator has proven its durability over may decades of rough use. The clamp is optimized for a 1 -inch mast, but adjusts down to 3/4-inch pulpit rails. We wish the strut was steel rather than carbon, allowing it to be bent for leveling.

Bottom line: Recommended.

Davis Telo-cat

We started with this one over 30 years ago. Specifically designed for beach catamarans, it attaches to the forestay turnbuckle, though the bracket can be adjusted to other configurations. This location is safe from sheets on a beach cat, even with a chute. We used these for decades, always getting multiple seasons from them.

Bottom line: Recommended for beach cats.

Schaefer Marine Little Hawk MK II

Easy to mount, extremely sensitive and highly visible, it looks a little fragile. That said, we havent been able to break one in two seasons. It remains the most sensitive after a year of blasting through waves, even more sensitive than our masthead fly.

Bottom line: Our personal favorite and Best Choice.

Schaefer Marine Cat Hawk

Like the Telo-cat, the mounting is designed for the forestay turnbuckle of a beach cat, but we screwed it to a home built rail mounting block and took it sailing. It was more responsive than the Black Max, steadier than the Little Hawk MK II, and easier to read accurately. We wish the tail was more conspicuous; we may spray the tail yellow. The indicator arms were a little too easy to move, but were also the easiest to read. We wish it came with the Little Hawk Mark II mounting, though you can always bend the wand and secure it somehow.

Bottom Line: Recommended.

While not as unbreakable as the DIY version, it is easy to read and the top-and-bottom stays make it quite damage resistant. Bottom line. We wish it were more responsive.

We’ve been sailing with bow wind indicators for 35 years and we’ve yet to figure out why they are not popular outside the world of beach cat and dinghy sailing. They don’t replace a masthead fly or tell tales, but we all use the same wind and what could be more valuable than knowing where the wind is coming from?

Mounting options is clearly a consideration when choosing a deck-level vane. Several of the models we tested have deck mounts as well as spar mount, and rail mounts.

• The the blue up-haul line protects the sensors on Drew Frye’s boat.
• The C-Vane easily attaches to 1-inch rail
• The mounting arm on the Schaefer Cat Hawk keeps in clean air.
• The simple Mini Hawk II is perfectly balanced. It’s large vane responds well in light winds.

Marine Wind Indicators

For boat junkies, thrill-seekers and everyone who eats, breathes and sleeps adventures, sailing is more than just a hobby; it’s a lifestyle. A sailboat is driven by the wind so make sure it has everything needed to let you sail off to the unknown destination with peace of mind. The weather offshore is unpredictable and can change rapidly so it’s essential to be aware of the current wind direction to take action when needed and keep your boat sailing in the right direction. And this is what a wind indicator does. It points out where the wind is blowing, assisting in vessel navigation and ensuring your safety. Knowing the current wind direction helps boatmen know when to raise the sails and where to direct them.

On our digital shelves, we handpick a comprehensive selection of premium wind indicators to help you get to your destination and back with confidence. We offer everything from wind wanes and spare wanes to airflow tels and mount hardware. The products provide the ultimate blend of quality, ease of installation and durability needed to help make your sailboat trip a safe, worry-free experience. Designed with style and functionality in mind, they come in a variety of designs and colors. You can opt for popular low-friction weather vanes with a strong, lightweight and balanced vane arm and durable support rod. You can also get top-notch tell tales and windsocks that will point you the airflow. So when sailing too slow or pinching, you'll be able to set the sails right and make your boat move faster.
