  2. Self-steering gear - Wikipedia

    en.wikipedia.org/wiki/Self-steering_gear

    The increased low wind capabilities of optimized, modern devices enable downwind steering down to 1.3 m/s apparent wind and 1.5 kn of boat speed [8] [9] – properties that make an electronic steering device nearly redundant and enable crossing the doldrums under wind vane self-steering. An increasing number of long distance regatta sailors are ...
