And I just received notice that a UPS package has been delivered - could it be the wire to hook up the compass?
Other than stringing this wire (never simple or easy on a boat), we are about ready for the first sea trials - without the rudder reference transducer. The autopilot will work without the rudder reference (see the St4000, which does not use a rudder reference), but it will work better with one.
Installing the rudder reference transducer will be nearly a project in its own right. Later.
Update: For the initial sea trial, I will *not* permanently install the compass. Instead, I will duct tape it to a suitably vertical surface in the cockpit. That way I don't need to pull wire to do the initial testing.
