I've known cruisers with every type wind-vane imaginable. I never heard anyone do anything but praise whatever they had.
I had an Aries
(Lift-up model). I put 80K miles on it and loved it. The only problems that I ever had would happen to any of them. I had a couple of paddles snap off due to getting hit by large seas. I also snapped off one break-away rudder
coupler. I had spares for each occurance and they were easily remedied.
I had a hydraulic auto pilot for those light air, down-wind, moments and motoring. Other than that, my Aries
wind-vane steered every mile with ease.
All wind-vanes take some time to get used to. They steer off of aparent wind
, so every time you have a gust of wind
and/or your boat speed changes, your coarse will change. That's simply law of physics. The first couple of passages, you may find yourself making unnecessary adjustments. Don't expect to steer a perfectly straight coarse with any wind-vane and you will be fine. They just don't work
