I've got one. Came with my 27' boat. Only had the chance to use it once for a trip of 8 hrs. Some motoring some sailing. Worked fantastic. The sea was a bit choppy and on one leg heading somewhat into the wind
, the occasional big wave would swing the bow around quite strongly. Funnily enough, I tried with the autopilo off and found it very difficult steering
so put the autopilot
back on and let it go. I was solo and back at port I decided that the autopilot was my new best friend : ).
My only concern was the current
it was drawing as I had also inherited with the boat some electrical
problems. I was concerned I would get to port and not have enough power to start the motor
, not so nice with the squally winds. But I had no problems. Probably if I was sailing all day with the autopilot on, I would want to have my solar
panel working properly and check the amps in and out of the battery
plus have the start battery
From my limited experience, I found the unit to work very well even when manual steering was not easy. If I get a few years solid work out of it, I would probably buy another one.
