Disclosed is a system for displacing the center of buoyancy from the center of gravity in a capsized craft and maintain the displacement until the craft is substantially re-righted. Buoyancy is provided such that the craft floats high in the water when inverted. Flooding ports and venting ports are opened to allow at least one hull to partially flood, eliminating the buoyancy previously provided by the hull. Elimination of this buoyancy causes a displacement in the overall center of buoyancy which begins a pitch, or roll about the craft\s longitudinal axis, which continues until the center of gravity is located directly under the center of buoyancy and the craft is substantially re-righted, although some pumping out of water in the flooded hull will be necessary.

A self-righting waterborne craft having a center of gravity, said craft being capable of floating when awash, comprising: at least one hull; means for partially floooding said at least one hull when said craft is floating inverted; and buoyancy means, located substantially amidships in an upper portion of and internal to the hull, for displacing the center of buoyancy of said craft below and to one side of the center of gravity of said craft when said craft is inverted with said at least one hull at least partially flooded, wherein said means for partially flooding and said buodancy means comprise the sole means for rotating said hull to a non-inverted position at which water at least partially flooding said one hull can be removed from said hull.
