Most should work but the interface with a wheel
could be an issue. Have a WindPilot Pacific Plus on my 35', 13,000# boat that worked all the way on a DDW sail to Hawaii
. The Aries
on our Westsail 32. 22,000# sailed the boat flawlessly for over 10,000 miles and then went another 20,000 miles with the subsequent owner.
Did have a problem with the Monitor on my current
boat but it was probably caused by a faulty idler sheave in the wheel steering
system. Pendulum Servo vanes work best with a tiller because of the direct, no loss nature of the tiller. Have seen boats as large as 50' with wheel steering
and Pendulum Servo vanes that report excellent performance, however.
