ABSTRACT:
A system for sailboats for the purpose of maintaining the trim or attitude of the hull in a level position and at the same time adjusting the rigging and keel. The mast is made so that it can tilt to port or starboard and apparatus is provided to produce a force or torque tending to urge the mast back to its upright position and to produce a righting moment on the hull. Alternative apparatus is provided to produce these forces. A rotatable keel is provided which is automatically adjusted when the mast tilts to compensate for the tendency of the craft to make leeway while under way. An auxiliary mast is provided, suspended from the top of the regular mast which is swung to port or starboard to keep the mainsail substantially upright. A horizontally movable jib boom is provided for the foresail and sheets are provided so that the helmsman can adjust the aspect of the foresail to keep it aligned with the mainsail when the mast tilts.
