My ancient AutoHelm 4000 does a great job in calm weather and upwind. I have used it in 40+ knots going upwind. It is hopeless going downwind in anything more than light-medium air and if the waves are running it can hardly even motor downwind. I think the very latest wheel pilot has vastly better algorithms for steering, but the wheel pilot mechanism itself has limited abilities.
