Windvane Self Steering - Video or Animation?

I was wondering if anyone has come across any good video or animation that really details how windvane self steering works??

I've read some material from Monitor Windvane and some other sources. And while I basically get it, a visual explanation would be super helpful. Also... I was trying to explain it to my better half and clearly I don't fully get it b/c I fumbled through it and she couldn't picture the equipment reactions i was trying to explain.

Thanks!!

Re: Windvane Self Steering - Video or Animation?

YouTube is a pretty good resource. Put windvane self steering in their search box and you'll get a weekend full of hits.

If you need a sanity check, I don't think anyone really begins to understand how they work, until you go out and trim for various points of sail on your own boat.

Re: Windvane Self Steering - Video or Animation?

I only watched the first video. It is interesting to compare the Sailomat vs the Monitor we have. The principles are exactly the same but some of the details are quite different. The Sailomat seems to have at least one more way to control the unit. We have a centre-cockpit and can do all adjustments from the helm position. From the video it appears that you need to set a control on the unit - that would be a non-starter with a centre-cockpit. Also note that both of these brands are zero-pendulums so work the same. Auxiliary rudder systems like Hydrovane work somewhat differently.

You really need to see these things in action to understand them. Movements of the wind vane are subtle and and movements of the pendulum are even more subtle and difficult to see. Also, setting up the sails correctly to balance the helm is absolutely critical so you need to look at the interactions.

Back home on Lake Ontario after something over 36,000 nm circumnavigator. Not surprisingly there is a lot of stuff I want to get done on Ainia both cosmetically and functionally. Getting an early start so it will be ready to go for next summer (Lake Superior?).

Re: Windvane Self Steering - Video or Animation?

Just bought a used Hydrovane. It came off of a sistership so length of struts should be correct. It has both emergency rudder, tiller pilot and remote.
Beyond it going in at true vertical what other issues should we be paying attention to during installation?
We also got the offshore kit with it. Beyond those spares what other spares should we be carrying?
Our intention is to use the vane on passage but remove it if coastal for a period of time. Have heard shear pin will fail if rudder is in the water during long periods of motoring. Find there are long periods of motoring even on passage. Any tricks or advice how to decrease stress on device when motoring?
What maintenance schedule do you do? With what specific products?
How do you store vane when not in use?
Any tricks to ease docking with Hydrovane in place?

Thanks so much.

Have had Fleming and Monitor in past. Both servo pendulums. Now with Hydrovane is there any change I need to make in my thinking ?


Thanks again.

This was a pretty clear demo of the Monitor system. At least I thought it was.

Otto-AP
Greta - GPS and nav instruments.
? Hermione- Hydrovane ?

Cute kids having fun. Done that passage. Totally psyched to spit up the anchor.

Thanks for the videos.

Can't help with the operation of the Hydrovane. When we considered one we were told that the transom has to be reinforced to handle the substantial loads of steering the boat (as opposed to turning the wheel with a servo-pendulum). We installed our Monitor using four large fender washers. With a Hydrovane you need much more. Might be able to find details on their website.

Re: Windvane Self Steering - Video or Animation?

K- thanks. Have planned for fairly intense reinforcement of sugar scoop already. Given I bought it from an outbound owner and have input from other outbound owners with them fully appreciate your excellent insight. They are now cruising South Pacific or eastern Med so unavailable. Person I bought from is quite ill so don't wish to trouble him. Was thinking non outbound cruisers using it could answer. Worth a shot.
Really like servo pendulums but wife refuses to give up swim ladder and sugar scoop. Big money to get swing gate and emergency rudder so Hydrovane seemed to make more sense.
Spent today in 19 degree weather unpacking crates looking at it and it seems well made and robust.

Re: Windvane Self Steering - Video or Animation?

Have a WindPiilot Pacific Plus auxiliary rudder vane like the Hydrovane. There is a lot of strain on the rudder as the vane actually steers the boat. Still, it did not require strengthening the transom to use it. Did use generous backing plates as well as the oversize washers that came with the unit. Steered to Hawaii without a problem even though it was thoroughly worked out with the DDW conditions and confused seas that saw the vane cycling through large deflections of the rudder to keep the boat on course.

Have never worried about balancing the boat with either a pendulum servo Aries or the hybrid auxiliary rudder system WPPP. Both boats had considerable weather helm at speed. Just moved the tiller over a few notches on the chain connection to the vane in the case of the Aries or dialed in some boat's rudder with the WPPP to compensate. Of course, having a tiller made the Aries a lot more responsive that it might have been with a wheel.
