ABSTRACT:
A sailboat apparatus includes a hull having a bottom, bow and stern portions along with a central portion and at least one mast for supporting a sail extending above the hull. The mast is mounted to the hull for side-to-side movement relative to the hull. A keel assembly has a keel extending below the hull bottom and through the hull bottom and attached to an elongated transfer shaft rotatably mounted to the hull and having the mast coupled to one portion thereof. The keel is coupled to another portion of the transfer shaft and extends from the transfer shaft through the hull bottom into the water so that movement of the mast from side-to-side rotates the transfer shaft and the keel in the opposite direction from the mast to stabilize the sailboat. Sealing is provided for sealing the hull bottom against the incursion of water through the keel assembly opening in the hull and may include having the transfer shaft coupled through journals and covered with the seals over the shaft and sealed to the bottom of the hull. Embodiments are disclosed which mount fluid cylinders to control the movement of the mast from side-to-side and one or more mast and keels may be utilized.
