Multi-hulled boat

Claim 2

A boat comprising two or more hulls having opposite top and bottom surfaces of similar contour, a deck structure interconnecting said hulls at a point approximately midway between the top and bottom of each hull, a sail for propelling the boat, a mast for supporting said sail, and means for relocating said sail at sea when the boat is in an inverted position including means for mounting said mast for rotation about said deck structure to a mirror image of the position of the mast when the boat is upright so as to permit said boat to operate effectively when inverted and when upright.

Claim 3

A boat as defined in claim 1, wherein said hulls are symmetrical about a central horizontal plane passing therethrough.

Claim 4

A boat as defined in claim 2, wherein said deck structure interconnects said hulls at a point belonging to said central horizontal plane.

Claim 5

A boat structure as defined in claim 3, wherein the configuration of the cross-section of each of said hulls is that of two scalene triangles having a common side lying in said central horizontal plane.

Claim 6

A boat structure as defined in claim 4, wherein the longest side of said scalene triangles form the side walls of said hulls to which is secured said deck structure.

Claim 7

A boat structure as defined in claim 5, wherein the configuration of said hulls is such that a vertical plane passing through the apexes of said scalene triangles divides the common side of said scalene triangles in the ratio of 1:3.

Claim 8

A boat as defined in claim 1, wherein said deck structure comprises front and back tubular cross-members secured at each end thereof to the side walls of the hulls and a netting secured to said tubular cross-members.

Claim 9

A boat as defined in claim 7, wherein said means for mounting said mast comprises a hinge structure rotatably mounted on said front tubular cross-member and having two holes therein spaced by 180*, a step bearing secured on said front tubular member on each side of said hinge structure for guiding said hinge structure, a pin guide secured to one of said step bearings, and a pin adapted to be inserted through said guide and through one of the two holes in said hinge structure for locking said hinge structure in a position suitable for fixing the mast in the upright position when the boat is inverted as well as in the normal sailing position.
