Sailboat, has solid body pivotally mounted to keel, where keel and mast share horizontal and transverse axes and are linked during rotation one-way coupling so that keel rotates independent of mast in direction of tilt

摘要

The sailboat (1) has a hull (2), a mast (5) and a ballast (3) that is connected to a keel (4), where weight of the ballast turns the keel and the mast automatically to an extended position. A solid body (9) is pivotally mounted to the keel, where the keel and the mast share horizontal and transverse axes. The mast and the keel are linked during rotation by one-way coupling so that the keel rotates independent of the mast along the transverse axis in a direction of tilt.
