I am very seriously considering a Hydrovane autopilot for my Union Polaris 36, a double ender.
My ship is worm-gear steered, and does not have facility for an emergency tiller, so the self-contained Hydrovane system is attractive for that reason. It will serve as a spare rudder, effectively.
Because of the boomkin and its supporting centre-line strut, I will have to mount the Hydrovane slightly off centre, perhaps about 6", but I am reminded that it will not affect the performance much, if at all.
What do you think, guys?
