IMHO the belt drive wheel pilots are good only for motoring in calm
conditions.
I've seen dozens of them that can't hold a course on a nice sailing day, much
less
rough conditions.

Well funny you should say that. Mine gets used mainly if I have to motor a
long way say from Balto ot Rock Hall back to my creek when there's no wind. If
it's a "nice sailing day" why would I want to use the autopilot? Although I
have tried it sailing and it works just fine. As far as rough conditions go I
wouldn't be out in those. :-)
