I'm pretty much of the opinion that the only automated course
correction on a sailboat, under sail, should be "Steer To Wind."

All my steering under sail will be done by the Cape Horn windvane servo
pendulum. The small electronic unit will just tweak the servo shaft while
under power with the primary effort to turn the rudder provided by the
boat's motion, just as under sail.
