Another vote for windvanes in general, but with a center cockpit
layout, the typical servo-pendulum vane requires very long lines between the wheel
and the pendulum. Often multiple turning blocks are required as well, and all of this kit leads to friction losses and excess free play due to stretch... all bad news. So, for such a boat the auxilary rudder type vane (Hydrovane, Sailomat
Pilot, and Autohelm
(vane, not autopilot)) types have great advantages. In particular, the Autohelm
vane drives the trimtab on the aux rudder via push-pull cables
, and the air vane can be offset to possibly avoid the mizzen boom.
Good luck with your decision.
