After we determined so as to add windvane steering coupled with a hydrogenerator to our sailboat, our focus was on the sensible features: conserving battery energy, including rudder redundancy, and enhancing our off-grid capabilities. It wasn’t till we sailed with the vane in a single day for the primary time that we got here to understand the transcendent thrill the units additionally ship. When the wind is each powering and steering the boat, a satisfying synergy of movement is achieved.
Steering within the earlier than instances had all the time been a battle the place fixed correction was required to keep up course, and the electrical autopilot was all the time on the again foot making an attempt to catch up. The windvane, in distinction, is a peacemaker that gives equilibrium utilizing pure physics, liberating the boat to go the place we’d like her to go as if she is aware of the best way on her personal. I by no means thought-about steering a battle, till unexpectedly it wasn’t. The vane represents a transformational change, and we fly the pink vane sail as a badge of honor marking our sailboat’s arrival into the next state of being.
Attaining steadiness with the ocean is cool. However banking amp-hours is cool too. Shutting off the electrical autopilot and steering by vane saves energy whereas on the similar time, the hooked up hydrogenerator creates energy. Not solely are these two items of kit mounted collectively, in addition they work collectively to steadiness the onboard vitality price range.
My spouse, Alex, and I are out cruising full time aboard our 36-foot Morris Justine. One in all our targets is to maintain the engine out of our battery charging equation and as an alternative rely completely on photo voltaic and hydropower. The 2022-23 Golden Globe Race is proof constructive that that is achievable. Many of the boats within the race, together with Kirsten Neuschäfer’s successful boat, Minnehaha, have been outfitted with the precise vane/hydrogenerator setup we selected for our boat. The truth is, the success of that gear on the racecourse all over the world is what helped us belief it sufficient to put in it on our boat.

A number of manufacturers of vane steering methods can be found within the market, and lots of sailors have constructed their very own. The methods are available in two varieties: One kind of vane controls the ship’s rudder to steer the boat. The opposite locks the ship’s rudder and makes use of its personal ancillary rudder to steer the boat. On the latter methods, the extra rudder additionally serves as an impartial spare ought to the primary steering system fail. The brand new breed of rudder-eating orcas off the coast of Spain is considered one of many threats to a ship’s essential steering system, so it’s sensible to have a backup (“Whale Watch,” January/February 2024).
We selected the ancillary rudder system constructed by Hydrovane. Their buyer help is superb, they usually talked us via a variety of challenges in the course of the set up. Sailboat transoms are available in all styles and sizes, and Hydrovane has quite a lot of mounting options to accommodate nearly all shapes. In concept, set up is easy; simply six bolts maintain the vane to the boat. It’s getting these six bolt holes drilled in exactly the correct spots that proved difficult.
In-water set up is inspired in order that measurements to the waterline and to vertical might be extra simply and precisely assessed. Our conventional transom angle made this venture difficult, as every part was overhead. Mendacity on a paddleboard below the again of the boat put me in the correct place to work. I rigged a tarp within the water below the again of the boat to catch something I’d drop. I additionally added lanyards on all elements for belt-and-suspender safety. A couple of issues did certainly go for a swim, however the security nets labored, and nothing went to the underside.

Putting in the Watt & Sea hydrogenerator was a lot simpler. Hydrovane sells the Watt & Sea machine they usually have additionally designed a mount for putting in it to the body of the steering vane, saving further holes within the transom. If this setup was ok for Kirsten Neuschäfer, it’s ok for me.
The whole set up was largely a one-person job and I did it alone; I estimate it was about 70 hours of labor to put in plus one other 20 hours to plan and measure earlier than ordering elements. It wasn’t a straightforward venture, however the directions have been wonderful, as have been the cellphone and e mail help. Drilling these six holes was worrisome, however the folks at Hydrovane have put in loads of these and have developed a system for measuring. They clarify it effectively, and it labored flawlessly. Possibly the most effective choose of venture effectivity is retrospection; if I have been to do that one over, I wouldn’t change a lot of something.
The hydrogenerator tilts down to be used after which tilts up out of the water when charging is full. Management traces make this straightforward to handle from the pushpit rail above. A cable runs from the drive within the water to a small and colourful Watt & Sea-provided controller mounted in a dry and out of the best way spot down beneath within the cockpit locker. A pair of wires then ship energy from the controller to the home battery financial institution.
A Bluetooth-connected app on my cellphone lets us observe manufacturing. Energy output is instantly correlated with boatspeed. If we may sail our boat at 12 knots, the Watt & Sea 600 would produce 600 watts of energy. At our extra typical pace of 6 knots, the generator produces about 200 watts of energy. Browsing down a wave at over 8 knots, I’ve seen it contact 400 watts. The generator retains producing day and evening, whereas our photo voltaic array solely works throughout daylight and solely places out prime energy for a number of hours round peak solar.
As with most main new gear, there have been some studying curves and challenges with the gear, some anticipated and a few not.

The Watt & Sea hydrogenerator have to be tilted up as soon as the batteries are absolutely charged. If we fail to elevate it out of the water at full cost, the corporate warns us that we’ll destroy the generator. The drive makes a faint noise when it’s time to drag it out, however we haven’t all the time heard it, and the human error issue right here has me nervous. I want it will shift to a “float” standing by itself like each different charging machine I’ve labored with and proceed to spin with out hurt ought to we overlook to elevate it out when a full cost standing is reached.
The vane rudder chatters when motoring. It really works like a magician after we’re crusing, however after we’re motoring or docking, we want it will disappear.
Eradicating the vane rudder from deck and reinstalling it’s tough. Dropping the rudder might be managed with the assistance of a boathook, however reinstalling it requires a visit to the again of the boat in a dinghy—a minimum of on our boat that’s the one solution to do it. With different formed transoms, you would possibly have the ability to accomplish this from a kneeling place on a swim platform, however even then, the boat must be stopped, and it wouldn’t be straightforward.
The reality is we need to take away and reinstall the vane rudder ceaselessly. It’s nice for steering the boat when offshore, however we don’t need it down when piloting near-coastal from buoy to buoy, dealing with the boat in shut quarters close to the dock, when motoring, or if we have been to see an orca coming for a go to (extremely unlikely the place we sail, a minimum of for now, however nonetheless). It’s additionally good to take away the rudder when at relaxation to stop marine development. Some kind of rudder pivot much like the pivot the Watt & Sea outdrive makes use of can be an incredible enchancment for this vane.
Each the vane and the hydro drive are vulnerable to catching seaweed and plastic within the water. That is straightforward sufficient to clear and is especially only a nuisance. However I also can think about {that a} snag on a lobster entice or different fishing gear may trigger vital injury. This gear isn’t supposed for inshore use the place fishing gear tends to dwell.

The vane construction could be a sharp hazard to a dinghy tied astern when at anchor in gentle and/or rolly situations. A pal’s dinghy was destroyed by his personal vane when a wake got here by and despatched the vane with the rudder eliminated down into the inflatable like a spike. Our onerous dinghy has a number of new vane assault scars—nothing too critical, and he or she lives on to battle one other day. We’ve realized from these mishaps and have developed more healthy dinghy tie habits. If there’s loads of wind to maintain the dinghy again, we are able to nonetheless safely go away her tied astern when at anchor. But when there’s any concern, we revert to both a side-tie or hauling her out. It’s good observe to haul a dinghy out of the water when not in use anyway to guard towards theft, marine development, and put on and tear. The vane provides another reason to drag her up and out.
One different consideration: The gear isn’t cheap, even with out set up prices, making this a critical funding. I ordered each instantly from Hydrovane. The Watt & Sea price $6,290, whereas the Hydrovane was $7,715 (this consists of delivery and nearly all set up and wiring provides).
Because the Eagles sing, “Each type of refuge has its worth.” Tradeoffs are plentiful right here. The vane will not be nice for coastal cruising, nevertheless it’s superior offshore. All issues thought-about, we’re delighted to have our new vane and hydrogenerator bolted on out again, and the sensible advantages are enhanced by the intangibles. Whereas different gear typically provides complexity and detracts from the alone-with-the-wind-and-sea expertise most of us search, vane steering goes in the wrong way. The vane provides purity to crusing. Electrical energy is neither wanted nor consumed, steering is not a battle, and the boat floats on in a silent, easy groove.

It does take somewhat getting used to. There is no such thing as a NMEA2000 cable connecting it to a chartplotter. We are able to’t set it to steer to a waypoint, and it gained’t keep a compass course. As a substitute, it merely maintains a relentless wind angle. When the wind shifts, so does our course. This steering method lets us go away the sheets untouched whereas the vane maintains optimum sail trim via oscillating shifts. When course modifications are wanted, a closed loop of line working again alongside the lifelines to the cockpit permits us to simply alter course to the brand new desired wind angle.
A faithful cult of sailors has been evolving vane self-steering know-how for the reason that Fifties. When you strive it, your thoughts opens, and the newfound steadiness turns into addicting. The vane works tirelessly all day and evening with out pay or grievance. It’s a chunk of boat package that may put your head into a brand new gear. A Bernard Moitessier kind of gear. A Kirsten Neuschäfer kind of gear. A headspace that may make you need to preserve crusing and by no means cease.
