Navman Autopilot

I have had a lot of grief I'm afraid. First of all I went through three pilots because the transistors kept on blowing - Navman swapped them out no problem but it took a whole season to get one with transistors which wouldn't blow. Then when the drive transistor blew the software was not smart enough to know about it itself so the clutch stayed in and the steering locked up - had to kill power to get control back. Finally on my moderate displacement (40 ft, 11 tons) sailing boat I simply could not damp the pilot enough to steer well - kept on moving the wheel by very small amounts and when the boat rolls it steers to amplify the roll. All in all bad choice for me, maybe it will work for you but I think they have geared this towards motor boats and light displacement sailing boats. When I asked 'how do I stop it moving the wheel every second' they said 'why would you want to do that?'
