You need an autopilot where you can alter the amount of response to a

At trolling speeds you need much more rudder angle to correct a
deviation than you would at higher speed.
However, if you are trolling rather than maintaining course to a
destination you ought to be able to accept a greater amount of yawing
about the set course anyway.

Frankly, I knew that - can you suggest one? Thanks.

Sorry, Larry-I did hesitate a bit before posting that in view of your
electrical
expertise.
Cannot suggest a make of pilot that would assist you as my last one was a
wind vane.
Now however I have got a Simrad wheel pilot which was very good when I used
it last season to steer compass courses.
However I am now on the point of hooking it into the output from the chart
plotter so it can steer me to a waypoint but have just seen your later post
about the uselessness of GPS based pilots at low speeds and since I have a
sailboat it looks as if this will not help me in light winds, so maybe I
will leave things as they are. It has a good fluxgate compass which you
calibrate by steering in slow circles a couple of times and, best of all,.no
belts or control lines across the cockpit. You can control the sensitivity
to yawing to minimise battery drain.
