ABSTRACT:
A sailing craft (1) comprising a center cross-plane symmetric hull (2,3) and capable of sailing in either direction is disclosed herein. Good skimming properties are imparted to the sailing craft (1) by utilizing the principle of the normative angle of inclination based on the stability and the effectiveness of the sail and keel function of the craft, this being realized by designing the bottom side of the hull (1) as a substantially flat plane enclosing an angle of from 10.degree. to 20.degree. with respect to the plane of the water line and providing relatively deep draught keel-rudder (821,101) which are equidistant with respect to the center cross-plane and preferably a sail (10) which is isosceles in outline for having a relatively low point of pressure. Boom attachments (25,26) edging strainers (30) and an automatic trimming system may keep the sail (10) in the ideal profile thereof while balancing the pressure point and the lateral point.
