True Stories

Golden Globe Update Day 113:

[GGR Leader Jean-Luc Van Den Heede sailing the Rustler 36 Matmut] was full of praise for his Hydrovane self-steering. “In a gale it has a big advantage because it is not steering the boat’s rudder, but has its own. This little rudder is far more efficient than the big rudder.”

– Jean Luc Van Den Heede on satellite phone call

“I am happy I did install the Hydrovane, especially that I saw on YouTube that at the same time 2 sailboats almost the same size as mine with the same problem. The crew had to abandon the the ships and left both boats in the middle of the Atlantic and lost everything … again thanks to the Hydrovane. It saved my boat.”

– Jacques Glaser, Amel Mango 52

“My wife and I have just completed a two month cruise with our new Hydrovane and it has performed beyond all expectations… If cruising I wouldn’t go to sea without one: strong, simple, reliable, an emergency helm and an extra crew member who never complains and doesn’t need a watch system.”

– Pete Goss, MBE, Frances 34

“So, I must tell you, and I mean this sincerely, the Hydrovane is simply a game changer for Quetzal. It’s just great and performs better than I expected… One other feature of the vane that I really appreciate is that it eases the load on the rudder and rudder bearings.”

– John Krestchmaer, Kaufman 47

“With just two of us on board, I wanted a system that was simple and effective to operate, and it has exceeded my most optimistic expectations by a considerable margin. It truly is our third crew member.”

– John Mennem, Jeanneau 45.2

“…it is still the most technically elegant solution i have ever seen for a wind vane… I was clawing off a lee shore on one side, and islands on another – winds were reported at 55 knots, and waves in the region were at least ‘boat length’ high and quite steep with the currents. This was an awful night and I was very afraid for myself, the boat and my equipment – I had new found respect, trust and comfort in the Hydrovane after that.”

– Steve De Maio, Contessa 26

In this recent Pacific crossing, the Hydrovane kept us on course (relative to the wind, of course) for several days at a time, requiring no tweaking or attention at all. If you can balance your boat and twist a dial, you can successfully operate a Hydrovane. Don’t leave home without one!

– Bill Ennis, Passport 40

“For the first time, we had to run downwind, under bare poles in gale force 8 conditions, with gusts to 50 knots – and don’t get me started on the sea conditions! Have you ever swallowed your tongue? Oh, and iVane, our wind-steering partner. What a gem! It steered 230 hard miles without even nut rations.”

– Brian Anderson, Hallberg Rassy 40

“The additional cash to purchase a windvane was almost too much… Just how good is this ‘Hydrovane’ anyway?”

After 29,000+ miles: “We’ve said to each many times that without doubt the most valuable piece of equipment on board was Casper – best purchase EVER. I will never own an offshore boat again that does not have this device.”

– Ryan Robertson, T 40

Windvane steering: why it makes sense for coastal cruising

• Will Bruton
• October 15, 2018

No electricity needed, built for gale-force conditions and currently experiencing 
something of a renaissance amongst 
cruisers; windvane self-steering makes sense for coastal cruisers as much as 
offshore voyagers. Will Bruton took 
an in depth look at the options 
and how they work.

‘The distance run was 2,700 miles as the crow flies. During those 23 days I had not spent more than three hours at the helm. I just lashed the helm and let her go; whether the wind was abeam or dead aft, it was all the same: she always stayed on her course,’ wrote Joshua Slocum in 1895.

The ability of his long-keeled Spray to hold course without input from the helm was instrumental 
in making her the first yacht to circumnavigate single-handed.

Few modern boats bear these inherently balanced characteristics, so some form of autopilot is necessary to allow the skipper to rest.

Even for crewed passages, it can take an enormous strain off the crew without draining the battery. Some insurance companies even count windvane steering as an additional crew member, such is its contribution to life on board.

Unlike an electronic autopilot, self-steering needs no power

One solution experiencing something of a renaissance, is windvane self-steering.

Requiring no electricity, mechanical self-steering gear was first designed in an age when autopilots were the preserve of large ships and heavy motor cruisers. The principle is relatively simple and pure physics.

What mechanical self-steering cannot do is hold your yacht on a compass course. However, as anyone that’s experienced a sudden wind shift or squall whilst away from the helm knows, steering to a wind angle is preferable most of the time as you are far less likely to crash gybe, and the sails remain correctly set.

Self-steering gear achieves this by presenting a vane directly into the wind. When the wind acts on either side of this vane, it tips, transferring this action through the mechanism below to either a rudder or a servo pendulum which acts on the main rudder, altering the boat’s course.

The two main systems

Servo-pendulum

A derivative of the servo-trim tab principle invented by Blondie Hasler, servo-pendulum self steering gear uses the speed of the yacht going through the water to push against the servo-paddle, creating a substantial force, which is then transferred to the yacht’s own tiller or wheel by control lines.

The wind itself does not provide the power for the steering; rather it adjusts the angle of the paddle, relying on the hydro-mechanical energy of the boat going through the water to do the work of steering the boat.

Popular before the advent of the small craft electronic autopilot, it’s particularly well suited to yachts under 40ft in length, and can be swung out of the water when not in use.

There are now several derivatives, including some available as a self-build kit. Amongst the Golden Globe Race entrants, models included Aries, Monitor, Windpilot and Beaufort systems.

One disadvantage of the servo-pendulum gear is that it uses the yacht’s rudder, meaning it does not double up as an emergency rudder should the yacht’s steering be disabled, although some servo-pendulums can be adapted.

Direct drive systems

Wind vane steering linked to a secondary rudder is the most inherently simple of the mechanical self-steering systems, but relies on a much more powerful transmission of force between a large-surface-area wind vane and the system’s own independent rudder.

Direct drive systems feature a large fully independent auxiliary rudder

This has the advantage of ensuring 
a back up steering method is already on board but also requires a heavy-duty installation to bear the load and strain that will be exerted.

One of the most popular models is the Hydrovane, which is now available in several different sizes and shapes depending on 
the boat it is being installed on.

The size 
and shape of the fabric-covered windvane is directly proportional to the size of yacht, and has been installed successfully on yachts in excess of 50ft in length, including multihulls.

When the boat veers off course, the 
wind hits the vane on one side or the other, deflecting it away from the vertical.

This then acts on a gear that converts 
this sideways movement into rotation to directly steer a relatively large rudder suspended from the boat’s transom via 
the installation framework.

Setting up windvane steering

Balancing the boat.

‘Before doing anything, you have to get the boat sailing well. It demands you take the time to get your boat properly balanced, correctly reefed and with no weather helms; so it actually makes you a better sailor!’ explains Nick Nottingham, who recently fitted a Hydrovane to his Hallberg-Rassy 42, Spellbinder . Nick is about to use the system on an Atlantic circuit.

Self-steering relies on a well balanced boat. As the wind shifts, the mechanism corrects

Self-steering gear works by adjusting the yacht’s course in relation to the apparent wind. The first step to making this work as efficiently as possible is to balance the boat and reduce the amount of input required.

Sailing conventionally, the yacht should be easy on the helm and not overpowered.

Setting the system for the conditions

Whether servo-pendulum or direct drive, most self-steering systems have one or more methods of adjustment for the conditions. In light airs, the wind vane will be exposed as much as possible to the wind, to exert the maximum force on the system, whereas in heavier weather, the vane’s height can be lowered, reducing the force acting on the system.

Some systems, like the Hydrovane, Monitor and Beaufort have different sized vanes that can be swapped, while the Windpilot and Aries allow the vane to be raked aft, presenting a shorter level.

With the wind vane attached, you are ready to remove the locking pin and engage the steering mechanism

On some set ups, the power exerted on the steering system can also be adjusted at the point where the wind vane meets its pivot, just like changing sensitivity on an electronic autopilot. By controlling the rotation of the rudder or paddle created by the windvane, you control how aggressively the system corrects the boat’s course.

Changing the gearing at the point where the wind input creates the steering output achieve an increase or decrease of ratio.

Engaging the system

To engage the system, set the yacht on course and adjust the wind vane so that the wind is flowing over it with the least resistance, like a blade.

If you a using a system with its own rudder, centralise and lock the yacht’s main rudder, simultaneously engaging the self-steering mechanism.

Once engaged, monitor how the system adjusts and double check your sails are trimmed correctly.

As the vane moves it will adjust the steering accordingly.

In heavy weather, reduce the system’s power to ensure the least amount of strain.

Self-steering systems work efficiently in strong winds but most will steer comfortably in light airs as well.

Course adjustments

When the wind vane is vertical, you are on course. When the vane is deflected, the system is adjusting course.

Changing the direction you want to go in is simply a matter of altering the self-steering system’s vane angle relative to the wind.

On most systems this is achieved by a steering line that can be run into the safety of the cockpit, meaning you do not necessarily need to adjust the vane itself directly.

Make small adjustments until the yacht comes onto the desired course, trimming the sails appropriately.

A standalone system?

Whilst self-steering systems offer a much more resilient option than an electronic autopilot for heavy weather, when there is no sailing wind, they cease to be useful.

Here an electronic tillerpilot has been plugged directly into the Hydrovane auxiliary rudder

For this reason, most cruisers also have a conventional electronic autopilot on board to steer under engine.

In the case of systems incorporating a rudder, many also make it possible to easily engage a tiller pilot onto the system’s auxiliary rudder for use under engine.

Self-steering on the Golden Globe Race

If there’s one place that mechanical 
self-steering fandom bordered on the evangelical this year, it was at the start of 
the Golden Globe Race .

50 years previously, Robin Knox-Johnston’s world first single-handed circumnavigation was steered by his own self-steering gear system until it failed 
near Australia.

Restored to her former glory, 
Knox-Johnston’s Suhaili joined the parade; along with Indian competitor Abhilash Tommy’s replica yacht Thuriya , which sports a commercially made Windpilot servo-pendulum system.

With this year’s revival competition using 1960’s technology and electronic wizardry strictly prohibited, mechanical self-steering systems are effectively the only option for competitors. Each has chosen carefully.

Competitors in the race are using a variety of systems including Hydrovane, Aries, Monitor, Windpilot and Beaufort.

Due to the nature of the boats competing being long keeled, they are ideally suited to mechanical self-steering, naturally holding course better than a modern hull. However, should systems fail and prove unrepairable, it will be hard 
for them to remain competitive in the race.

Why You Need a Wind Vane for Your Sailboat

September 24, 2021 by Travis Turgeon 1 Comment

Many of today’s offshore cruising sailboats utilize a type of autopilot equipment called a windvane. A sailboat wind vane is a mechanical self-steering system that requires no electricity, fuel, or manpower to operate. It’s the perfect addition to bluewater cruisers and offshore sailboats. While a mechanical self-steering wind vane can’t hold you on a compass course, they’re more accurate than human steering over long distances. By reducing the overall mileage of a passage, you’re able to save time and money on your journey. Alternatively, a windvane is essential for short-handed or single-handed sailing. It gives the skipper a much-needed break from the helm when conditions allow.

How Does a Wind Vane Work on a Sailboat?

Mechanical wind vane systems are relatively simple in concept. Once mounted at the boat’s transom or somewhere along the stern, wind prompts the elevated vane to adjust the rudder or wheel steering system, putting your sailboat back on a wind-based course dictated by the captain. The idea is that you won’t have to make constant adjustments in variable winds. Automatic adjustments reduce boat heeling and allow your vessel to remain trim in the water. 

In other words, wind vanes use wind and water resistance to return a ship to course when wind chages direction.

Sailboat Windvane Gears Vs. Electronic Autopilot Systems

Two primary self-steering systems are standard for bluewater cruisers and offshore sailboats: wind vane steering gears and electronic autopilot systems. Both systems have advantages, and many sailors choose to install both systems on their boats. 

Electronic Autopilot Systems 

Electronic autopilot systems are the modern answer to self-steering. They’re easy to use, work without wind, and are an excellent option for near-shore cruising and short-term offshore sailing. Autopilots are also compatible with multi-hull vessels, unlike windvane systems. 

The downfalls to these systems can be daunting, though. Electronic systems are complex and have numerous parts: displays, wiring, plotters, motors – the list goes on. To run an electric autopilot system, you’ll also need a generator. Most even have two generators, using one as a backup for reliability. As you’d expect, they also come with a higher price tag. 

Self-Steering Wind Vane Systems

Windvane steering systems take a more traditional approach to self-steering. They rely on the wind to operate your boat on the desired course. Wind vane steering systems require no electricity, little maintenance, have few moving parts. They also come in several variations to fit your boat in the best way possible. Another massive benefit of a mechanical sailboat windvane is its robust build. This allows reliable and powerful performance in heavy weather conditions. 

There are also several downfalls to a windvane system. They do not work in the absence of wind or under power, can add weight and stress to the boat stern, can be initially expensive to purchase, and won’t work on multi-hull vessels. 

Types of Sailboat Wind Vane Systems

All wind vane systems direct a boat to a wind-based course, but they each do it differently. 

Servo-Pendulum Wind Vane 

Servo-pendulum windvane systems are the most common commercially available system, and they are a favorite among most sailors. The reliability for offshore sailing is a huge selling point. It re-affirms why these are the “classic” wind-driven autopilot systems. 

Main steering servo-pendulum systems have control lines running from the primary steering quadrant to a wheel or tiller. As the wind pushes the pendulum, it directs the boat’s steering by way of the primary rudder. Because of this, the system is solely dependent on the power of the wind. The stronger the wind blows, the more force the system provides to push the boat back on the desired course. 

Rudder steering servo-pendulum systems have the pendulum rudder connected to the primary boat rudder. It works almost the same as the “main steering system,” with a few minor differences. The wind pushes the pendulum rudder to the side, forcing water to pull the boat’s main rudder to change steering. The advantage of this system over the prior is that it involves fewer mechanical components, making it easier to check issues and fix any problems. The disadvantage is that it can be a bit trickier to set.

One of the biggest downfalls of either servo-pendulum system is that the pendulum rudder can not replace an auxiliary rudder. Unlike an auxiliary rudder, its one-dimensional operation makes it unable to run the system if the primary rudder fails. These systems can also create a cluttered cockpit due to the lines running from the steering quadrant. Lastly, servo-pendulum systems generally require more consistent maintenance and more common repairs. 

Auxiliary-Rudder Wind Vane

Unlike servo-pendulum steering systems, auxiliary-rudder wind vanes are entirely independent of all other aspects of the boat. Instead, the main rudder is locked, and the auxiliary rudder steers the vessel after setting a powerful windvane to the desired angle. The main rudder is often locked to the left of center or slightly at an angle to balance the helm. One of the most significant advantages to these systems is that if the primary boat rudder fails, the auxiliary rudder can act as a replacement to steer the boat. 

There are some important considerations to make when purchasing auxiliary-rudder wind vane steering gear. First, auxiliary-rudder windvanes put a significant amount of stress on the vane, making it vital that the model and components are well designed and made of quality materials. If you can source well-made parts, there is minimal risk while out at sea. There are very few moving parts and no critical lines attached to the system. Second, these systems are big, heavy, and bulky. Having such a massive piece of equipment at the stern of the boat isn’t always ideal in every scenario. Lastly, auxiliary rudders can be awkward to operate when the mizzen is in use on ketch-rigged vessels.

Trim-Tab Wind Vane

Trim-tab windvanes are less common than they used to be after the emergence of the steering technologies listed above. The system works by attaching a “tab” to the main rudder. The small surface of the trim tab makes it easy for the wind to move it from side to side, which then forces water over the primary rudder in the opposite direction to keep the boat on course. Those with the appropriate skills and know-how can even construct a trim-tab themselves, although we recommend that they do not rely entirely on a self-made system. 

The major drawback to trim-tabs is that the ability to fine-tune the system is somewhat limited in heavy conditions. 

How to Install a Sailboat Wind Vane System

Installing a wind vane on your boat is relatively easy, but it still takes a bit of planning. 

Initial Considerations

All windvane models require installation at the center of the boat’s transom or as close to the center as possible. Depending on which system you choose to run, you may need to account for the steering lines that operate the system. Steering lines are approximately a quarter of an inch in diameter and need a clear path from the wind vane to the boat wheel. You may redirect the lines with steering blocks, but be aware that each block adds friction and lessens the overall efficiency of the steering system. 

Balancing the Boat

Windvane gears adjust the course of a boat using the wind force at the surface. For this to happen efficiently, you’ll first need to ensure your boat is balanced and sailing as intended. Take your time to get the weight distributed evenly. You’ll also need to reef the sails appropriately so as not to be overpowered. 

Adjusting the System for the Conditions

Regardless of the system, nearly all sailboat wind vanes have one or more adjustment features so that you can optimize performance in various conditions. When wind conditions are relatively light, you should expose the vane as much as possible so that the system receives the most force as possible. In heavy winds, however, you can lower the windvane to reduce the impact on the system. In some cases, the wind vanes have sensitivity adjustments where the vane meets the pivot, so you may not need to adjust the height as weather conditions change. 

How to Engage a Sailboat Wind Vane System

Most wind vanes are relatively adaptable and can adjust to fit a variety of hull types. Some vanes are even customizable to bolt directly onto the boat. As with any other object you bolt to your hull, plan to through-bolt everything with the appropriate bedding and backplates for maximum security.

Operating a sailboat wind vane is far less complicated than you might expect. There are four standard steps to engaging a windvane:

• Deploy the Gear : To do this, attach the wind paddle and unfold the rudder to be placed in the water. Doing this should only take a few minutes at most. 
• Connect the Control Lines : Control lines run from the windvane to the boat wheel and may have steering blocks included in the setup. The system may require you to make a few knots or use some hardware, but again, it’s a relatively easy process once you’ve completed it once or twice. 
• Balance the Boat and Set a Course : With the wind vane deployed, balance your boat, set the course to the desired point of sail, and adjust the windvane to engage the steering. 
• Evaluate the Course and Adjust as Needed : Adjust the vane to steer more accurately after evaluating your approach. Course adjustments are made by rotating and trimming the paddle to match your course.

Perfectly balancing your boat is one of the easiest ways to make your self-steering wind vane more efficient in the water. A vessel with poor balance or trim will not just sail inefficiently, but it will put unneeded stress on the wind vane system.

Thanks for the useful information. However, you didn’t mention anything about the usefulness of wind vanes in light or downwind sailing. You mentioned the issue of a mizzen and auxiliary rudder, how do I understand that (as we sail a ketch and thinking about installing a Hydrovane.

Wind vane steering

It’s the green version of an autopilot, helming your boat while consuming no power. sarah curry advises how best to use a wind vane steering system.

The overall concept is simple: a non-electric device mounted on the boat’s transom has a vane that takes a signal from the wind. Based on this input, the boat is steered – by various mechanisms – on the apparent wind-based course you set.

The beauty of an apparent wind-based course is that as you sail along in ever fluctuating winds, your boat stays properly trimmed. Your course follows the wind, but over long distances this is much more efficient, comfortable, and surprisingly faster than a magnetic compass course.

Setting and Adjusting a Course

The first step is to sail your boat on the desired heading; easy enough. Let’s say this happens to be on a beam reach. Set a balanced sail plan and trim the sails for that point of sail. It’s important to feel the helm; the boat should almost be steering herself by the time you are ready to engage the windvane.

Set this course (a beam reach) for your windvane by feathering the vane so it points directly into the apparent wind, and engage the unit. As your boat falls off course the new wind angle will push the vane over and the system will take control to bring you back to that beam reach.

The apparent wind at the top of the mast (which is where your wind instruments are measuring from) may be different from the apparent wind the vane feels. Attaching a piece of yarn to the top of the vane is helpful for determining the wind direction.

Has your electronic autopilot made you lazy when it comes to sail trim and boat balance? We are all guilty. You may ignore your autopilot grinding away and wearing itself out, but your windvane will tell you if your boat is not well enough balanced by not keeping course. Bear in mind she’s one of those silent and observant type teachers – but she’s a good one; you’ll become a better sailor for it.

A pole on the jib or genoa is a must for downwind sailing with a windvane; a collapsing headsail puts the boat off balance with every swell.

Keep an eye on the heading. Tradewind sailing is lovely with fairly consistent wind direction, but if there’s a wind shift over time your heading will also be changing. Adjust course back to your desired heading by changing the vane angle and readjusting sails for the new point of sail.

Such course adjustments are done on most units by pulling a line that can rotate the vane through 360 degrees – to whatever point of sail you want to be on. This course-setting line is usually an endless loop that you run into the cockpit, so that you can adjust your heading without having to reach over the boat’s stern. This line is best run down a lifeline so it’s reachable from the cockpit, but not in the way.

Minor tweaking is fairly normal – to fall off or head up a few degrees. But if the wind shifts more drastically, let’s say 20°, then your course will also shift by 20° following the wind. To get back on track Pull on the course line to change the vane by about the same amount (20°), so you are back on the desired heading. At the same time you are trimming your sails to this new point of sail. In a circumstance where the wind suddenly backs, you will probably jump on the wheel, trim your sails and then adjust the vane to suit.

All types of windvane steer to a wind-based course, but do so by very different methods.

Sevo-pendulum system

Most servo-pendulum models steer using the ship’s rudder via control lines led to the ship’s wheel or tiller. Brands are Aries, of which 14,000 have been sold since 1968, and which is now based in Amsterdam, Cape Horn (direct connection to quadrant), Fleming, Monitor, Sailomat, Navik (out of production), Norvane, Neptune, South Atlantic, Voyageur, and Wind Pilot Pacific. These systems cost £1,500-£5,000.

As the boat falls off course the wind angle changes and the vane is pushed over. Movement of the vane rotates the in-water servo oar (also called paddle or blade). Once moved from dead ahead position, the flow of the water pushes the oar to one side with force. A connecting line is pulled to turn the wheel or tiller so the main rudder moves to bring the boat back on course.

Auxiliary rudder system

Auxiliary rudder systems are independent from all other aspects of the boat. As a complete second steering system and rudder, the loads they must deal with are far greater in comparison.

After the vane is feathered into the wind, the main rudder must be ‘locked off’ so it is stationary. While setting up and with hands on the wheel to feel the helm, you’ll find a sweet spot where the boat is tracking nicely. Often the main rudder won’t be centreline, depending on how the boat sails, the conditions and the seas. Lock the main rudder in that comfortable position, and it becomes a giant trim tab to the auxiliary rudder. The system is then engaged and the auxiliary rudder will take over steering the boat.

The three main Auxiliary Rudder system types, all of which function differently, and which cost approximately £3,000-£5,500, can be tuned even further if you’re someone who likes to tune and tweak.

Build Your Own Self-Steering Windvane

For the short-handed sailor planning long ocean crossings, a self-steering windvane is not essential but darn close to it. For boats with stern-hung rudders, a self-steering windvane can be constructed with readily available materials and a modest level of skill.

It’s all about leverage. There will be an air paddle which will weathercock to the wind and provide enough torque to move the trim tab which we are going to mount on the trailing edge of the rudder. The trim tab will be a slender, high aspect ratio blade, and we will add some “balance” to it–a little bit of the blade will lead the shaft–all so as to lessen the torque required to move the trim tab when the water is flowing over it and thus increase the amount of leverage the air paddle has over it.

Let’s start with building the trim tab. The trim tab should be somewhere around 10 to 15 percent of the area of the rudder. We decide on the correct diameter of shaft for the blade. In my case this was a 5/8″ diameter stainless steel shaft. We then drill several (say four) holes to take through-bolts which will hold the wooden blade to the shaft. Below is the rough blade held to the shaft with 1/4-20 bolts. Notice the thinner piece on the leading edge, this will give it some balance.

We then permanently attach the blade with the bolts and 3M 5200 and begin fairing:

Following fairing and shaping we will then encase the entire blade in fiberglass roving and epoxy, this will add a great deal of strength and durability.

Now we have to mount it on the end of the rudder. But before we start drilling any holes, we need to work out some geometry. The trim tab must be mounted such that the air paddle will attach at the “no action point”; that is, where the trim tab shaft intersects the axis of rotation of the rudder. This is important because if the air paddle is not attached at this point, the turning of the rudder will wag the air paddle back and forth resulting in poor performance. Hopefully the diagram below will make this clear:

For the gudgeons on the rudder I used 1″ thick pieces of ash which I cut like opened jaws to slide onto the trailing edge of the rudder. They were finally attached with through-bolts and plenty of 3M 5200. For the bottom gudgeon I drilled a slightly oversized hole for the shaft to drop down through. On the inside of the hole I put a few laminates of epoxy and fiberglass roving to minimize friction and make it snug (note: I’ve since inserted a nylon bushing, which works better).

Similarly for the upper gudgeon EXCEPT that I opened the hole to the outboard end so that it formed a “U” and then closed it with a small U-shaped piece of plywood bolted on top and facing inboard (see pics below). Why? So that the trim tab can be removed for servicing.

And finally there is a third gudgeon at the rudder head, which is simply screwed onto a wooden cleat mounted there, again so that it can be easily removed.

Now we have come to the issue of attaching the air paddle. First of all, the air paddle needs to be balanced. This means the axis where the trim tab shaft runs through it is also the center of mass, or if the shaft was held horizontally and the air paddle free to rotate it would not choose to do so absent any wind. Since the plywood air paddle has weight, this will require a counterweight for which I used a regular shaft zinc clamped to a wooden dowel.

With our air paddle and counterweight constructed the last remaining item is the engaging mechanism. I opted for the simplest possible, simply boring a hole up a rectangular piece of timber for the shaft to pass through, and then sawing about halfway up from the bottom (see above photo). The air paddle and counterweight are bolted at the top, while at the bottom, on either side of the bored shaft hole, are 1/4-20 bolts with big handles on them. The opposing nuts are set in epoxy. Thus the air paddle can freely turn on the shaft until I tighten the bolts, when it clamps onto the shaft and the windvane is thus engaged.

And that’s it.   So far this vane has steered me over 30,000 miles.  I can get it to work in winds down in the 3-6 knot range, and then it has steered the boat while running before a gale under bare poles.   In order to work well in light airs the gudgeons must be greased from time to time.  This can easily be accomplished in the water while donning a mask and snorkle.   Just lift the trim tab up a few inches (it cannot actually pop out of the bottom gudgeon before the blade runs up against the upper gudgeon–with the little plywood cap on, of course), clean, grease, and set back down. 

Now one peccadillo I have found with this type of steering vane is the tendency to over-steer. It tends to shove the helm too fast and too far on either side, causing the boat to sail a slalom course. One cure for this is to attach shock cords to your tiller lashings which will greatly dampen the effect. The size and setup of the shock cords will vary from boat to boat. Here is my current setup shown below:

Sailing With a Windvane

• By Alvah Simon
• Updated: December 9, 2019

Once found only in the ascetic realm of single-handed sailing, self-steering gear has become ubiquitous on cruising boats, even fully crewed ones. That’s because a self-steering unit serves as an additional hand that possesses relentless concentration at the helm; subsists on only amps or lubricants; and, if properly trained, does what’s asked of it without question or complaint.

Reliable remote control of the helm relieves the fatigue and monotony of following a compass course at night. It allows time for sail changes and adjustments; horizon sweeps for ships; attentive navigation; and that quick dip below to check the bilges and grab a hot drink. Without question, self-steering makes for a more relaxed, enjoyable and safe voyage.

But the debate over which kind of self-steering is best for a sailboat — electric or windvane — rages on. I may be an old-fashioned belt-and-suspenders kind of sailor, but I believe both systems have their different strengths and weaknesses, and therefore complement each other. In other words, any vessel that is configured in a way that can accommodate both methods should do so.

In this scenario, the more robust mechanical sailboat windvane would be employed in heavier weather, while the electric autopilot would be used in light airs and under power, where directional corrections are provided not by the wind, but by a fluxgate compass. It is important to understand that while the electric autopilot maintains a steady compass course, a windvane is set to maintain a desired angle off the apparent wind, and therefore will follow any wind shifts or changes in wind velocity. While this does keep the sails perpetually in trim, the course must be monitored closely when in confined waterways.

That said, if forced to choose, I would go with the mechanical windvane, hands down. Vanes don’t rely on the ship’s electrical power supply, which serves as the last link in a long chain of delicate electrical components and breakable mechanical parts. Across the range of types and brands, mechanical windvanes generate amazing power in rough conditions (when needed most), coupled with notable durability. Almost 30 years ago I purchased an already well-used Aries windvane. It has faithfully followed me from boat to boat, and around the world, with clear indications that it will outlast me. On the other hand, I have an overflowing box of spare parts cannibalized from the many electric tiller-pilots I have chewed through in that same period.

Types of Sailboat Windvanes

Introduced by the indomitable Blondie Hasler, founder of the OSTAR solo transatlantic race in 1960, the original sailboat windvane consisted of a direct coupling of a horizontally rotating (vertical axis) vane to a trim tab on the aft edge of a transom-hung rudder. Once the vane was fixed to the desired angle off the wind (using a round base plate with notches spaced at 5-degree intervals), any course change rotated the large vane like a weathercock. This in turn twisted the tab to one side of the main rudder, driving the rudder in the opposite direction, thus bringing the vessel back on course. The advantage to this system was its ease of construction and low cost, but it was best adapted to the waning style of transom-hung rudders. Also, a large vane was required to harness sufficient wind to power the trim tab. Therefore, especially in light airs, the tall, heavy vanes often reacted more to the yaw and roll of the vessel than to the wind, resulting in erratic meandering.

However, from this early and rudimentary concept, two sophisticated yet distinct types of vanes evolved: the servo-pendulum system (SPS) and the auxiliary rudder system (ARS). Both SPS and ARS systems employ a counterweighted horizontal- or vertical-axis wind vane to activate an appendage in the water, but the similarities end there. (To confuse the issue, there is now a hybrid system called the servo-driven auxiliary rudder, or SAR. But by first addressing the two basic concepts, a clearer understanding of this marriage of ideas will emerge.)

The SPS system — best represented by brands such as Aries , Cape Horn , Fleming, Monitor and Sailomat — uses the movement of the windvane to horizontally turn an independent servo-rudder (essentially a separate oar or paddle) that is deployed into the water. As the boat moves, the laminar flow of water presses against the positive lead on the servo-rudder, generating sufficient power to aggressively swing the servo-pendulum, or windvane, in one direction or the other.

While it is the power of the wind that directs the angle the servo-rudder presents to the passing water, it is boat speed through that water that exerts the considerable pounds of pull on the lines that run from the servo-rudder and through a series of turning blocks, ultimately connecting to the tiller (or, in the case of wheel steering, a drum in the center of the wheel). More simply, the servo-rudder does not turn the boat; it pulls on the tiller or rotates the wheel, which in turn moves the main rudder.

Perhaps the main drawback to this concept is the limited throw of the lines, as the distance of arc through which the pendulum swings is limited to the width of its supporting frame, an average of approximately 10 inches. This is no issue when connected to a tiller because one can fix the lines at the optimum point on the helm: high for more power, lower for a greater turning angle. But depending on the stop-to-stop ratio of a wheel steering system, the length of pull may not be sufficient to effectively control the vessel. This problem can be exacerbated by center-cockpit designs, as longer line lengths may stretch more, further limiting the effective length of pull.

The ARS system, best represented in the market by Hydrovane , employs an altogether separate appendage to steer the vessel. The boat’s main rudder is usually fixed amidship (or angled slightly to offset a lee or weather helm) and a second, auxiliary rudder, directed by a windvane, takes control of the steering. Thus, it is not only a self-steering device, but can also serve as an emergency rudder. Considering that all four of the Mayday calls I monitored on one of my Pacific crossings related to steering failure, this redundancy has considerable value. Because of the forces placed on this rudder it must be robust in construction, well fixed to the vessel, and of sufficient design and size to handily maneuver substantial tonnage.

Pros and Cons of Sailboat Windvanes

There is a heated online debate among some of the manufacturers and distributors of the respective systems, each dismissing the supposed advantages of the other’s design concept while touting their own. I have sailed with both servo-pendulum designs and auxiliary rudders and found both to be practical and reliable; the final decision, to me, comes down to the type of vessel to which they will be attached, the steering system onboard, the conditions of sailing most likely to be experienced and the budget. In my opinion, the auxiliary rudder is more sensitive in light air, which is the average condition found in many recreational sailing areas. I’ve found the servo-pendulum model to be rock steady in conditions so rough that the average helmsperson would be exhausted within an hour.

But there are advantages and disadvantages to each approach. For example, the auxiliary rudder windvane has no provisions for being lifted out of the water to clear flotsam and seaweed; it can affect the backing characteristics of a vessel; and there’s no dedicated, engineered, breakaway “weak spot” when colliding with something like a submerged log. (In such instances, most servo-pendulum rudders simply flip up out of the way, and are popped back in place with the pull of a line.) On the other hand, auxiliary rudders don’t require lines that obstruct the decks and cockpit, a significant advantage depending on the placement of the helm.

To the latter point, perhaps too much is made of the difficulty in fixing, releasing and adjusting the tension of the lines on an SPS windvane. I corrected this problem with a $5 double jam cleat. Instead of using the typical link in a chain to connect to the tiller, I run my lines through an eye bolt on the tiller and back to the jam cleat. I can ease or tighten the lines balancing friction with precision; introduce infinite increments of bias to help balance the boat; and even when under tremendous pressure, immediately release the lines in an emergency situation.

A subtle but potentially important advantage of the SPS windvane is its natural aversion to broaching. As a steep wave slams into the quarter, the vessel can violently swing sideways. However, this same sudden sideways force pushes the servo-rudder in a direction that immediately tries to turn the boat back down the face of the wave. But even that point could be countered with the claim that by fixing the large main rudder in place, as in an ARS, substantial lateral stability is added to the vessel, thus minimizing any penchant to broach.

When mounting either system, the latest sailboat design trends — open, aft-entry cockpits and drop-down transoms — present new challenges. Hydrovane makes the unequivocal claim that its ARS windvane can be mounted off-center without affecting performance. Offsetting the vane opens access to the sugar scoop and/or the boarding and swim ladders. But as drop-down transoms, in particular, become ever beamier, there is less flat and fixed space available for robust windvane mounting. Depending on the stiffness of the vessel, one would not want to push the vane too far outboard for fear of lifting the auxiliary rudder clear out of the water on a heavy heel.

All SPS manufacturers stress the importance of meticulous centering during initial installation. Adapting to these new transoms, Monitor has introduced the SwingGate system to its windvanes. This is essentially a pivoting pushpit, much like a garden gate, with the vane attached. When the gate is open the boarding platform or swim ladder can be accessed, and when the gate is closed the vane sits firmly fixed amidship.

While completely appropriate for trimarans, windvane steering is not well suited for catamaran designs due to the dual rudders and high bridge-deck clearance.

As to pricing, there is no denying that the basic ARS units cost from 25 to 40 percent more than SPS models. Acting as the boat’s main rudder demands that the auxiliary rudder and mechanisms be constructed from heavy, high-quality materials. But if one chooses the swing-gate option, the additional cost of the gate structure must also be factored in.

Summing Up Self-Steering

When choosing a self-steering system for your sailboat, closely assess the design features of your boat and the conditions you will most often encounter. If you intend to make any kind of extended passages, consider a high-quality mechanical self-steering unit, possibly coupled with a lighter electrical system. Often, the two can be combined, offering the precision of fluxgate steering with the power and toughness of mechanical systems (see “ A Hybrid Self-Steering Solution “).

After the initial expense of purchase and installation, there will be no piece of equipment on your vessel more prized than your mechanical self-steering. I don’t know of a single long-distance sailor who has given a name to the roller-furling system, nor of one who has not named the windvane. Be it SPS or ARS, called Esther or Otto, trust me, out there on the Big Blue you will have many long and meaningful conversations with it.

But like all relationships, this one requires practice and patience. First and foremost, do not ask the windvane to make up for sloppy sailing. Balance your boat, starting with waterline trim. Keep the weight out of the ends and ensure that the sails are appropriately sized, set and trimmed to the conditions. Excessive heel is not only slow, but places the boat on lines that the designer never intended, resulting in poor tracking. Ensure that the windvane is not blanketed by superstructure or fed turbulent air via barbecues, solar panels or davits. Experiment with different settings, such as blade angle and line tension, to understand and optimize performance in various conditions.

Models that employ a mix of metals should be disassembled, cleaned and lubricated regularly to minimize electrolysis. When reassembling, use a high-grade barrier cream on all fasteners.

All models benefit from an occasional bath of scalding-hot fresh water to dissolve any buildup of salt, minerals and solidified grease.

And finally, for those concerned that these protruding, industrial-looking structures may ruin the lines of an otherwise lovely vessel, remember: “The rougher it gets, the better they look.”

Building a self steering wind vane

 For my winter project I intend on building a self steering wind vane. I have purchased Bill Belcher's book " How to plan and  make your own" but before I get started I wanted to ask the Vega group if anybody has tried this and what model do you feel is best suited for the Vega. I have never seen a wind vane in real life so I have limited knowledge. I have walked around both Seward and Homer boat harbors and nobody has one on their vessel. I have only seen pictures. As a side note, I would like at some point to install a outboard kicker bracket to the transom so the wind vane would have to operate with that installed. Any advice from experienced hands would be appreciated.  

I have no experience and in spite of that recommend this book: Self-Steering for Sailing Craft: John S. Letcher Jr.: 9780877420422: Amazon.com: Books Perhaps you could find it in a library. I read http://windpilot.com/n/pdf/bookeng.pdf but don;t really remember it. Cheap at twice the price.  

Self-Steering Gear -- Build a trim-tab based wind vane or autopilot self-steering system for your boat

Tomfentonvega2977beowulf.

My vega came with a Monitor windvane system. It was easy to use, incredibly accurate and robust, and we used it all the time even on quite short passages. It was over-engineered for the Vega and would have been quite capable of steering a boat twice the size or more. The mounting was heavy and took up most of the transom. I briefly had a Rival 32 with a Windpilot Pacific, which took up far less space, and there was room beside it for a boarding ladder, so presumably also for your outboard bracket. Tom  

I have no knowledge about windvanes, sorry ... but I sure would be interested in the install of that outboard kicker bracket. I'd be grateful if you'd keep your us posted on how that develops. I've been thinking about doing the same thing.  

On my first Vega in the mid 70's it came with a early model Hasler windvane. I used it extensively and was very pleased with the performance. The Hasler is a pretty basic unit,not too difficult to build a similar unit, but would not be as powerfull as the later models.  

As powerful as you want to build it if home built. Plus the satisfaction of several thousand dollars still in your pocket and the satisfaction of having done it yourself. Duckworth mag has a lot of info on building naca rudders and foils which will help if you go with a second rudder and trim tab. The really nice thing about a trim tab is that a balanced naca foil turns very easily but can control a large load like a rudder. Made with positive feedback, this system will correct much faster than a helmsman could. An added benefit is your tiller pilot can be tied to the trim tab meaning very little power required and little mechanical wear with the obvious benefits. Another benefit is no hodgepodge of lines and blocks in the cockpit! Gordon On 9/9/2016 11:01 AM, coe.richard@... [AlbinVega] wrote:  

Hello, I just left Alaska a year ago. Did you buy your Vega up there? And do you plan sailing up there? Very curious. Someday, I want to sail up there, then to Kodiak.  

Hi Gordon, I agree the second rudder with a trim-tab seems like the best choice. The servo-pendulum style is more modern and powerful but the sweeping pendulum motion really reduces transom space for things like outboard mounts and swim ladders. So I think I will try the second rudder with trim-tab. I like the redundancy of a spare rudder. I just wonder if anybody else has tried this style and how effective was it on all points of sail? I like the idea of the system being smallish and removable, or to at least swing upwards out of the water to reduce drag when not needed. It seems like the second rudder style are very large compared to the sleek servo pendulum.  

Hi Craig, Yes, I purchased the Vega in Juneau and moved it over road on a trailer using truck and ferries. My idea for sailing is getting to know the boat in AK waters but going south as soon as I can cause its so freaking cold up here!  

Trim tab or pendulum. Both have their pros and cons. Trim tab system lighter and less complicated but will stick out a ways. Read and reread all the data available before your final decision and design. Gordon On 9/9/2016 3:03 PM, alaskaflyfish@... [AlbinVega] wrote:

Hi All, Interesting to read the comments on self steering systems. I don't have the time to build one myself so was looking at affordable self steering systems. I was wondering if any Vega owners had had experience of the Hebridean wind vane?  

I looked at the Hebridean wind vane kit and was impressed on its simplicity. It seems that it would work as advertised and replacement parts would be easy to fabricate. It is a pendulum style wind vane so it is efficient and powerful. The down side is that it would dominate your transom with its sweeping motion and would leave little room for outboard motor brackets and boarding ladders etc.. unless modifications to the attach brackets could be made to extend further aft. At this time I am interested in the Aux Rudder w/ trim tab style. It takes up less room on the transom and can be used as a back-up rudder if needed. Lots to think about, there is no easy answer. The Hebridean is inexpensive compared to others and may be a good choice for that fact alone. Cheers. From: "dade_jeremy@...

Hebridean self-steering wind vane

“well worth investigating”

TOM CUNLIFFE The Complete Ocean Skipper

“I’m impressed… the vane performed well on all points of sail, including downwind… the servo pendulum system took control to the extent that it could sail a course with the sails badly set” DAVID PUGH Editor, Practical Boat Owner

Build your own servo-pendulum wind vane from a kit

The Hebridean wind vane is an innovative version of the tried and tested servo-pendulum self steering system for sailing boats steered by tiller or wheel. The Hebridean  has crossed Atlantic and Pacific oceans but is also quick and easy to mount for weekend coastal sailing or jaunts across the Channel, Minch or other strait/sea.

Stern freeboard The kit fits yachts with stern freeboards from 600-1000mm (stationary). It is designed specifically for DIY construction. The Hebridean can be tilted up out of the water or lifted off the stern and stored on the guard wires. Or partially dismantled for storage below.

Horizontal vane axle The Hebridean is the only serv0-pendulum vane with an actual horizontal vane axle. One of its unique design features allowing boosted performance, simplified construction and enhanced efficiency in all conditions. John Fleming’s analytical genius was responsible for the innovative geometry on which this landmark development in servo-pendulum windvane design depends.

Simplicity For confidence at sea or in remote locations, the simplicity of its components and assembly crucially allows the unit to be maintained with tools usually found onboard. Building the Hebridean yourself is a hands-on “course” providing you not only with a good understanding of its workings, but also substantial confidence in your ability to maintain it anywhere.

Wood When sourcing your own wood you need 4m of suitable hardwood at 145 x 20mm (EU standard). The longest plank is 1800mm to make the pendulum/paddle for 1000mm height transoms. Here is the wood cutting plan .

Affordable The Hebridean offers DIY sailors the opportunity to build an affordable wind vane in wood and stainless steel, with no welding, bearings or plastic cogs in the main H2 Kit. (there is one worm and wheel in the optional Remote Course Adjustment Kit which can be viewed in action in this youtube video ). All the metal components are prefabricated (drilling and some surface finishing required) ready for you to bolt to the wooden frame. The build requires basic wood-work skills and tools. And several days of absorbing and highly rewarding work.

Wheel steering too A “drum” kit for connecting the Hebridean to wheel steering is available.

Notice from Ian Kirkwood

When John’s health got worse, he asked me again to take on the project. I am an enthusiastic fan of his highly ingenious version of the servo-pendulum self steering-system. I sailed in company with John on and off for a decade — using my own Hebridean (I was his first customer in 2013).

Our Hebrideans steered us around Scotland’s northwest coast and isles. We made three trips in company to the Faroe Islands. On the first of these I sailed happily solo. All thanks to the Hebridean. Dying winds foiled an attempt to reach Iceland: our boats lay calmly hove-to overnight a few miles off the Butt of Lewis. Plan B proved to be a fabulous voyage down the length of the Atlantic coast of the Outer Hebrides. A highlight was anchoring off Callanish in blazing sun.

I hope to continue John’s personal style of service. Please allow a generous lead time as I get used to stocking the components and preparing Hebridean kits while maintaining their high quality…and a reasonable kit price in times of rising costs.

About Aries

Born out of need, designed to last..

The origins of the Aries Vane Gear date back to 1964. Englishman Nick Franklin wanted to create a wind-generated autopilot, suitable for a large variety of sailboats, with different transoms and rudder layouts, operated by both tillers and wheels.

The Servo-Pendulum System was a winning formula. The boat is steered by its own rudder, which is the most efficient way to steer a boat. The force needed to steer is generated by the speed in the water and is more than sufficient to get even the heaviest cruising sailboats back on course.

Since the 60’ies, the Aries has been available in multiple models. Now we’re back to one model, suitable for all boats, like the Aries was intended by Nick Franklin. It has a proven track record with many circumnavigations and ocean crossings in bad weather. 

Lean Nelis has taken over Aries in 2015. He brought the company’s workshop to Amsterdam where he is still building and rebuilding every sailor’s favourite crewmember.

"In a gale it has a big advantage because it is not steering the boat's rudder, but has its own. This little rudder is far more efficient than the big rudder.". - Jean Luc Van Den Heede on ... Windvane steering: why it makes sense for coastal cruising Self-steering gear achieves this by presenting a vane directly into the wind. When the wind acts on either side of this vane, it tips, transferring this action through the mechanism below to either a rudder or a servo pendulum which acts on the main rudder, altering the boat's course. The two main systems. Servo-pendulum Why You Need a Wind Vane for Your Sailboat A sailboat wind vane is a mechanical self-steering system that requires no electricity, fuel, or manpower to operate. It's the perfect addition to bluewater cruisers and offshore sailboats. While a mechanical self-steering wind vane can't hold you on a compass course, they're more accurate than human steering over long distances.

James Explains the ... Episode #183 - Sailomat Self Steering Wind Vane Hello Friends,On this episode I introduce you to our newest crew member, The Sailomat 3040 Wind Vane that wil... How to Properly Use a Windvane The action of air vanes on most mechanical self-steering units is dampened by a counterweight set below the vane's pivot point. This helps keep the boat from yawing excessively, as the air vane is never truly edge-to-the-wind for more than an instant. In effect, it is the equivalent of the damping control found on most electronic autopilots. Build Your Own Self-Steering Windvane For the short-handed sailor planning long ocean crossings, a self-steering windvane is not essential but darn close to it. For boats with stern-hung rudders, a self-steering windvane can be constructed with readily available materials and a modest level of skill. It's all about leverage. There will be an air paddle which will weathercock to the… Steering Wind Vane: A Guide to Efficient Sailboat Navigation A vital component within a naval vessel's steering mechanism is the rudder—a movable surface attached to a vertical axis below water level at the stern (rear) end of a boat or ship. Steering wind vanes are masterfully engineered to connect with this pivotal rudder system through various linkages—creating an intelligent partnership with ... How Does A Sailboat Wind Vane Work? The edge of the vane faces into the wind so that when the boat veers off course the vane topples over. That force is communicated to the rotating steering, which moves the tiller. The wind vane also connects to the water flowing past it. Together, these two forces work to steer the boat. The harder the wind blows and the faster the boat moves ...
