Hi John & Sherry,
Thanks for your generous offer. Order details for the vane cover are below, but in the meantime….
Our hydrovane (a.k.a. “Scarlet”) has been a complete star the last 18 months. We’ve covered over 18,000nm, with her steering for most of them. Our autopilot died on us about half way through our adventure, but we found that Scarlet filled in quite nicely even while we were motoring, as long as there was even the lightest of winds. I must admit, that she took a little getting used to (the tips on your website are very useful, but we discovered them 12 months too late!), but now that we have the hang of her, I can’t imagine why any yacht would a) be without one, and b) want to use any another system.
At one point, crossing the Bay of Biscay at the start of our trip, we lost our wheel steering in the middle of the night. Fortunately the main rudder still worked, but it was very reassuring to know that if that went too, we’d still have scarlet to steer us on. At another point, we got knocked down sailing to Colombia, and the force of the wave that hit us twisted the top half of Scarlet through 90 degrees. Sadly that put her out of commission until we made landfall a few days later, but despite our worst fears, all we needed to do was release a couple of bolts, and gently crow-bar her back into place….. she was good as new again, with not even a hint of damage to the vane. I bet the plywood vanes of other manufacturers wouldn’t have stood up as well.
I’m not sure how old Scarlet is, but if the previous owners of Skardu put her on before they started their circumnavigation, I have to guess that she has at least 70,000nm under her rudder, and she’s still going strong!!!
On that note, I’d still very much like to order a new RED vane cover. Ours is currently wearing through and looking a little faded, and we don’t really want to change Scarlet’s name to Rose!
It might be a bit tight to have the package reach us in NZ before we set off again, so if could, could you be so kind as to send it to the following address instead. It may also make shipping cheaper/easier.
Many thanks again,

Hi John. Well, my dear old Rival now sports a nice new Hydrovane, to the envy of my nearest neighbour!! The actual assembly of the unit was just as straight forward as you told me at Southampton (have to confess, I didn’t really believe you!!). Actually, it was a piece of cake! Making the wooden pads to compensate for the angle of the transom was another matter. What a pain in the a**! I tried to get too clever, I think, using templates and a protractor to measure the angle, and then trying to translate that to the pad. Failed miserably!! In the end I just did it by eye, taking the old view that if it looks right, it is right. Worked perfectly. Don’t know why I didn’t do it that way in the first place. Would have saved me a few hours of work. All that is left now is to go out to play!!
By the way. You guys certainly now how to package your product. The first (in truth, the only) difficulty I encountered was getting the parts out of the boxes! The ‘fragile’ stickers are definitely a euphemism. Now I have seen the Hydrovane up close and personal, I can see it is about as fragile as my Landrover!
I’ll let you know how I get on with the new ‘crew’ when I get a chance to take ‘Ocean Sunrise’ out to sea, but that may be a few months yet. I don’t think I will have any problems though. The product just looks right. Looks good on the boat too. The only drawback with my new ‘crew’ that I can foresee is that it wont stand its round in the pub!!!!!! Hey Ho, its an imperfect world!
Cheers, and all the best to all.

The vane worked great! AS I knew it would given my past experience with the RVG unit.
On Feb. 10th we finally relaunched Windsweptt II. My step-son flew in from Pensylvannia (after a day’s delay for the 18″ snow they got) and we sailed the boat back south to our area. We motored throughout the night but by morning we had 18-20 knots of apparent wind. First time we sailed the boat, new mailsail and everything to shake out. But the vane steered the course as steady as it could in 5-6 foot of slop, variable wind directions and strength.
My stepson couldn’t believe how well it steered the boat. We had motored all night utilizing the auto pilot and that didn’t really hold the course at all……yawing 15-20 degrees around the course. The vane held to a degree or two!

Of course you can use my quote on the vane. I have waited years to get my hands on the Hydrovane and have had quite a bit of discussion with others about it already.
Thanks for all your help and wish you continued success on sales. Incidentally, the first time I coveted the Hydrovane was 25 + years ago when I built a boat from a bare hull. That was a tight budget project and I couldn’t afford to buy the Hydrovane so I used a competitor’s unit that simply was not rugged enough for the boat and the way I sailed it. It failed three different times, the last on a 13 day trip from Florida’s west coast to Bermuda with my 66 year old mother as crew! We had to hand steer the last 10 days through absolutely the worst weather I have sailed in on the Atlantic!
But it has all worked out. I sold that boat with the vane and now I have an even grander boat, and although she is almost 4,000 lbs heavier, the Hydrovane handles her with ease!I look forward to many more sailings with no problems.

So far this thing is a beauty. Tracks very well even with an offset and underpower. Testing will continue, but so far you were right about how easy this is …
- pick and course and stabilze the boat
- pull the pins and turn vane leading edge into the wind
- and she tracks in a straight line
was able to make small course changes by rotating the vane – boat simply tracked around. more tests under sail on the next windy day

From the blog http://www.wheatstrong.com/hydrovane.htm
Wheatstrong has a Hydrovane windvane which steered for over 15,000nm during our Pacific voyages. The Hydrovane is an auxiliary rudder type windvane, rather than a servo-pendulum, so it has no lines to the wheel. The idea is that you trim the sails and adjust the boat’s rudder so that the boat is on the point of sail that you want, then use the wheel-brake to lock the boat’s rudder. Then you turn the leading edge of the vane into the wind and engage the mechanism and it steers using its own small rudder (about 36x10x2 inches, nylon).
I ordered a hydrovane with a longer shaft so that the gearbox and head are above my sternbox. The install was very easy. All you have to do is mount the Hydrovane vertically with the bottom of the shaft two inches above the water. It can be mounted off center if you need to. I drilled only four holes in the transom for the bolts for the two mounting brackets: two holes above the deck just below the caprail and two about a foot above the waterline. I made teak pads to fit between the mounting brackets and and the hull and had stainless steel backing plates fabricated to distribute the load on the inboard side of the hull. I faired the lower teak pad with epoxy to keep it from getting too thin on the upper edge.
The vane’s angle of attack, and therefore the heading, are adjusted from the cockpit using a small (1/4″) continuous line that turns the hydrovane head. I ran the line through a sheave with a bungee cord on the end of it; I attached the bungee to the port cleat on the cockpit coaming so you just reach back and to the left from the helm in order to adjust the vane. Course corrections essentially involve steering to the new point of sail, balancing and trimming the sailplan, setting the main rudder trim, and setting the windvane angle of attack. It takes a few iterations to settle down but then you’re good until the wind changes or you need to change course.
The Hydrovane worked very well when sailing to windward, pretty well when broad reaching or running and not so well when beam reaching.
The KP44 sails easily to weather and can be balanced to maintain a beat even without a windvane. It was easy to get the boat balanced and the windvane steering on a close reach or close hauled.
The hydrovane steered well with the wind on the aft quarter or from astern. Even running DDW was no problem for it as long as the sail plan was balanced and the seas were not confused.
I found our KP44 difficult to balance well enough to sail consistently on a beam reach without some main rudder movement. The boat would end up heading up or falling off in gusts or lulls and over-power the hydrovane’s smaller rudder. I think this probably would not have happened with a servo-pendulum type, since they can steer with much more force by moving the ship’s rudder. Hydrovane has since come up with a six-inch longer rudder as an option.
The Hydrovane can be locked with its rudder amidships by inserting a pin in the shaft at the gearbox/head. This is easily done from the deck. Once locked down the Hydrovane rudder exerts no influence. You can motor all you want with the Hydrovane locked down like this but I think it must generate a little drag and is probably needless wear on the Hydrovane as it tends to vibrate from the prop turbulence.
For motoring long distances in calm seas we remove the vane, lock the main rudder ‘midships, and use a Simrad TP30 tiller autopilot to drive the Hydrovane’s tiller. I had a mount and tiller extension built for a tiller autopilot on the pushpit and used that to drive the hydrovane while motoring. This worked very well in fairly calm conditions. But it would get in a feedback loop and spiral off course if seas were big. But then you remove the TP30, fold up the bracket, and sail in those conditions.
In cases where we are not going to use the Hydrovane for extended periods of sailing or motoring we take the hydrovane rudder off. This involves pulling a pin from the base of the shaft where it goes through the top of the rudder. You have to be at water level to do this so being in a dinghy or stern-to at a dock or quay is helpful. But if you’re agile you can climb over the transom and squat on the hydrovane support; hang on with one hand and use the other to pull the pin. The rudder is heavier than water so I have it secured with a length of line as a precaution at all times. Once the pin is pulled I just pull the rudder up using the line. Putting the rudder back on is the reverse process and is a little trickier when hanging on with one hand because you need to hold the rudder at the right orientation to line up the holes for the pin.
- No lines to steering wheel
- Can serve as emergency rudder
- Almost maintenance free, no rust or corrosion
- Simple install, unobtrusive
- Requires a light touch to get everything balanced and staying on course, but extremely reliable once it’s ‘dialed in’.
- Cost $4500
- Finicky on a beam reach
- Cannot pull rudder up easily, have to pull a pin and remove it from the base of the shaft (unlike other types which can swing the rudder up out of the water)
We had to handsteer on only one passage, to the Va’vau Group, Tonga, when it was 35-40 knots from astern with 25 foot following seas. The boat would surf down the waves and spin out at the bottom in the windshadow of the wave if the helmsman didn’t take corrective action. So we had probably 20 hours of hand steering over the course of a year. Not bad.
Our passage from Hawaii to San Francisco included a heavy gale in the last 600 nm with winds up to 50kts true (according to B&G). “Irene” stayed on the same point of sail, with a triple-reefed main and a storm stays’l, while we stayed below, only popping up every 15 minutes to scan the horizon and marvel at the size of the waves.
KP44s are well known for weather helm – in San Francisco bay we often sail with too much canvas up in ‘the slot’ and end up having to wrestle the wheel to leeward to maintain course. Reefing and trimming properly eliminates this problem, and saves the arm muscles. A servo-pendulum rig will turn the wheel against a large force in a strong wind so you may get away with an over-powered rig for longer than you will with the Hydrovane. In that same wind the Hydrovane will be overpowered by the weather helm. The vane will go all the way over and turn the Hydrovane rudder until it is stalled and the boat will head up anyways. Once you reef and trim, the Hydrovane does fine in pretty much any wind.
I think having the Hydrovane made me much more aware of helm trim and sailplan balance simply because it was essential to the proper operation of the device. In fact, we had a crew member on for our passage through Mexico to the Galapagos and he never did get the hang of adjusting the Hydrovane.
Hydrovane is now producing the bigger rudder (six inches longer with the same profile). If I start another refit to go cruising again the bigger rudder will be on my ‘buy’ list ($625 ugh). Also on my list would be the new ‘stubby’ vane (12 inches shorter and 8 inches wider) because the standard vane collides with my wind generator mast/outboard crane on certain points of sail.
One important thing that I really like about the Hydrovane is the simplicity of the system and its heavy-duty, bullet proof constuction. It’s just really well built and not a lot can go wrong with it. It requires no maintenance other than to wash it with fresh water and detergent, let dry, and spray with WD40 – ONCE A YEAR. Nice.

Believe me, single-handedly, single-handed in storms up to Force 12 was not fun and I would have betrothed myself to my “Harry” Hydrovane once I got back to land safely!

Subject: My Hydrovane
I purchased a Hydrovane about one year ago. My boat, which is a Pearson 35 sloop has been out of the water in Raiatea, French Polynesia. I recently went there from Seattle, carrying the Hydrovane as airplane luggage and installed the unit. The components you provided were definitely the correct size and combination for my boat.
As soon as the installation was complete, we sailed 1200 miles to American Samoa without any “trials”. The moment we left the breakwater and had the sails up, I engaged the unit and it sailed a good course. There was no drama or learning curve. On that passage we hand steered for a total of about 3 hours, during which the boat was very unbalanced by an unfavorable sail combination. We mostly had light following winds. We did not jibe once! I guess I should be ashamed, but when we were well away from any land in the tradewind, we just slept all night. I am extremely pleased; if the unit had not functioned well my marriage would be on the rocks.
I did have one problem about which I would like your comments. On two occasions I either hove to briefly or backed the boat up to set an anchor without putting in the rudder lock pin and I discovered that the whole control unit had shifted in position on the rudder tube. I presume it was twised out of position by the tiller. This occurred even though the bolts were all quite tight. I guess the bottom line is that the system will not tolerate any backward movement of the boat at all without the rudder locked? Any comments or suggestions? (EDITOR’S NOTE – The answer is yes to locking the rudder when hoved to)
I had one observation which might be of value to other owners: We had about 12 hours of strong wind during which we sailed downwind with only a small “spitfire” jib. I started out with the jib trimmed far out but the boat kept rounding up and the unit could not hold a good course. I then sheeted the jib in tight, even though we were running, and that kept the bow from rounding up and allowed the Hydrovane to steer a good course with us travelling about 5 knots.
It is obvious that a great deal of thought has gone into the design and manufacture of this extraordinary device. The lack of lines running through the cockpit to the wheel is a big plus. Thanks very much. You may quote me however you see fit.

I did not get a chance to test the Hydrovane until I set out on my annual cruise. I have just returned after 540 miles cruising to the Isles of Scilly and return to Chichester. Rotten weather including several gales – a good trial.

It simply never lost the plot – the ________ would often not let me brew a cup of tea before going off course.

The installation pics you asked for and a couple of others. Hope it didn’t jam your computer for too long.
Installation a breeze with no problems at all. The pads were made at home and required only minor adjustments to the concave of the stern, with a sanding disc on an angle grinder for perfect fit. All in all it took 2 of us about 6 hours. The hardest part stretching the cover onto the vane.
As a matter of interest I had no contact with any other owners of a Hydrovane prior to order but as we were taking the vane off the pier and back home for the cover fitting, we were stopped by a couple who recognized the vane. They had sailed out from England in a steel ketch 15 years ago. They sang the praises of Hydrovane having sailed 12,000 miles and only steering 200 miles. Of course they wanted a look at a brand new one straight out of the box. He asked if Derek Daniels had sold it to me.
Last weekend we had the delight of the test sail when 3 blokes had 3 days in Queen Charlotte Sound. The cross over Cook Strait was 10-12 kts on the nose so no problems there. The return trip 28kts reach with some slightly on the beam. Again no problems. With careful reefing and trimming we averaged 7.2kts for the 28 miles home.
We are absolutely delighted. It is now only a month to our departure for the circumnavigation of the South Island, Pacific islands next winter!!
A couple of small points. In the instructions perhaps you could include torque settings for the bolts. I made a guess and took them all down to an even 55 ftlbs.

During all this our Hydrovane self-steering kept us on course and pointed correctly to the seas for 2 days without needing any adjustment. It has performed well in light conditions as well- well worth the money we spent. The crew was able to get needed rest.
In my opinion very few electric driven pilots could have held us on course in that kind of sea. We have a solar panel but did not see the sun for about 2 weeks so don’t count on it entirely. During the bad weather wind generator did well. Our water and fuel conservation is going well. Fortunately during the gale we were already 200 miles offshore so we did not need engine; don’t think we could have motored in the heavy seas. We are certainly happy we took the offshore route.

In and of itself, the Hydrovane is a wonderful machine. It’s a, fundamentally simple design that is well engineered and well built, with numerous mounting options. If you can inspect one up close, you’ll see what I mean.
As for my experience with the Hydrovane – I’d have to say that it is one of the best pieces of equipment I have on the boat. I have an ’84 Swan 46 that I have sailed perhaps 25k nm on, from the Caribbean to the Chesapeake, and from California to NZ. In these past ten years the Hydrovane has required almost no maintenance, yet has provided countless hours of dependable service. I have often sailed short-handed because of my confidence in this “third crew member”.
I believe that at 49′ you are at the upper limit of the machine’s capability. However, to really get optimal performance – no matter what size boat you are on – you have to be able to balance your boat out well. The Hydrovane merely tips the scale this way or that, so to speak. If the boat is over canvassed, or the sails not trimmed properly, then the Hydrovane will have a hard time compensating, especially in a larger boat. A key control factor seems to be the offset of the main rudder to steer the boat a bit leeward to compensate for the boat’s tendency to head up as it hits small bursts of speed.
IF THE BOAT IS WELL BALANCED, the Hydrovane will work in practically all points of sail, and all wind speeds. I have used it in light air with a spinnaker, and fully reefed in 40 kts of wind in the Southern Ocean. The conditions that challenge it occur when the wind velocity is changing frequently, or when there are significant and sudden wind shifts. But this is probably true with all wind vane steering units. Dead down wind in light air can be tricky as the apparent wind is so low, and provides little energy to turn the rudder.
That said, the other features I like about the Hydrovane is that it can immediately function as an emergency rudder, and it is also easy to add a small tiller autopilot for motoring in calms, and to have as a backup to another mechanical unit you may have.
If you have any more specific questions, let me know. I have no complaints whatsoever with this product. It is a great thing that John Curry and family have become involved making access to information and parts more easily available than ever.
All the best, and good luck with your planning – it’s all well worth it.
