Abstract
A boat is disclosed which is particularly adapted for operation in rough seas. It includes a closed support hull, open support structure extending upwardly from the support hull, a deck mounted above the support hull and on the open support structure, a closed stabilizer hull laterally spaced from the support hull, and open connecting structure between the stabilizer hull and the support hull thereby permitting tall waves to pass over the hulls and through the support structures to provide a vessel for transporting motor vehicles, passengers and the like through open, rough seas.
Claims5
A watercraft comprising:
- an elongated closed support hull;
- a deck positioned immediately above said elongated closed support hull with the load from said deck being distributed so that said support hull provides substantially all of the support for said deck;
- an open truss framework extending between said elongated closed support hull and said deck for providing support for said deck and longitudinal rigidity for said elongated closed support hull, said deck being spaced from and located above said support hull;
- stabilizer means consisting of a closed stabilizer hull of substantially less length and displacement than said elongated closed support hull, said stabilizer hull being located on one side of said support hull in an asymmetrical arrangement;
- open connecting structure means extending between said deck and said closed stabilizer hull for maintaining said closed stabilizer hull in a laterally spaced position a sufficient distance from said elongated closed support hull to greatly reduce rolling motion of said elongated closed support hull and to maintain said deck in a generally horizontal position;
- and
- drive means operatively connected to said elongated closed support hull for contacting the water and providing a driving thrust to the watercraft with the drive means being controllable to permit various modes of operation, including forward, reverse and steering.
