ABSTRACT:
A sail on a cylindrical mast provides an aerodynamically shaped leading edge automatically oriented into relative wind, and a smooth shape behind the mast automatically adjusting for changes in trim of the sail. Flexible rib pairs opposite the mast are clamped tantentially to full length battens, the battens defining the shape of the ribs and the orientation of the leading edge.
