Abstract
Apparatus that maintains a sailboat sail in a position where maximum power is derived from the wind. The apparatus includes a wind vane that responds to directional changes in the wind and sends an electrical signal to a motor that adjusts sail-positioning lines as needed. The new position of the sail is communicated to the wind vane and the motor is shut off.
