ABSTRACT:
A boat having a mainsail and a conventional rudder. The mainsail is supported by a mast and a pivotally mounted boom. A blade is pivotally mounted toward the free end of the boom about an axis that is substantially parallel to the mast. The blade acts as an auxiliary rudder for steering the boom and setting the angle of the sail. Though the boom pivots, the blade may be held parallel to a pre-set direction, so that the leeway component of the force of the wind on the sail is held substantially constant.
