On a very old lady, with a lot of charme, I've found an old Robertson AP100 autopilot. Hydraulic pump is perfect and very well kept. The AP100 has been tested at sea, and is working. Nothing to say. But... coming to your personal experience, what about the reliability of that controller? Anyone of you has any serious experience on that? Can we rely on that old analog device or it's surely recommended to turn toward another stuff? In that case, would you trust more a Raymarine (Evolution + P70R) or better a Furuno NavPilot 700/711?
