Abstract
Embodiments of the present invention are directed to a passive, automatic wing-control mechanism for sailing vessels. A cam is attached to one end of a rotatable mast as part of a rotatable wing, and a tensioner is configured to exert a constant force perpendicularly against the cam. When a wing is in a no-go sailing angle with respect to an apparent wind, the cam does not exert a torque on the mast. When the wing is outside the no-go sailing angle, the cam exerts a counter-torque to a torque caused by the apparent wind acting on the rotatable wing, causing the wing to remain at a predetermined angle with respect to the apparent wind.
