ABSTRACT:
A sailboat which includes a hull and a sail assembly with the sail assembly being rotatable with respect to the hull. The rotational axis of the sail passes through the center of the sail so that equal wind force is applied across the sail with respect to the access of rotation of the sail. Rotation retarding structure in the form of a detent or in the form of a frictional drag operates between the sail assembly and the hull. The sail is mounted between a pair of elongated rods with each of the rods being removably secured to a mounting member which is rotatably mounted upon the hull.
