Yes I have done the sea trial calibration. But that is done whilst motoring at a steady speed in flat water
The rate of turn is determined by several factors, I have a full keel
boat which turns slowly. The amount of rudder applied during auto tack is just not enough compared to the amount that I apply when I manually tack the boat. Why do I want to auto tack? Because I like to single
hand in the San Francisco
Bay when at times lots of tacking it needed.
Also when the boat wanders off course the AP ignores it for quite a while.
I know that there are numerous adjustments that I can make, but I was hoping for some shortcuts!
