SINGLE-HULL SAILING SHIP WITH A ROTARY RING

摘要

The invention relates to a single-hull sailing ship comprising rigging with a mast (7) attached by a leg (6) onto a ring (3) rotatably mounted about the hull (1) by the force of the wind, with at least one ballast keel (51, 52) also attached to the ring. The ring (3) is also rotatably mounted about the hull (1) by a mechanical retaining force (9, 12, 17) acting against the force of the wind so as to keep the pressure at the leg of the mast (6) substantially constant. The invention enables the rigging to be arranged in the best position for the optimal transformation of the force of the wind into speed.
