Sail mast for a sailing craft, in particular a boat

摘要

Sail mast for a sailing craft, in particular a boat (2), which can be turned by means of the mainsail (3) which is firmly connected to it; at the top section of the mast (1), a fore wing (6) is rigidly connected to it, and turns when the mast (1) is turned, thus providing an enlargement of the aerodynamically effective area at an almost optimum angle of attack. <IMAGE>
