Claims
- 1. A high speed ship comprising a hull structure having a bow portion and a stern portion and being normally supported above the surface of the water at a design waterline when in operation, a forward strut depending from the bow portion of the hull structure subtended by a first buoyancy means, at least one aft strut depending from the hull structure at approximately midship, said at least one aft strut being subtended by a second buoyancy means whose beam is equal to or greater than its length extending laterally beneath the ship, said at least one aft strut and said second buoyancy means providing more than 70% of the buoyancy for the ship during operation to maintain said hull structure above the surface of the water during operation and said forward strut and first buoyancy means providing 30% or less of the buoyancy of the vessel during operation; and wherein the center of buoyancy of the ship is located within the periphery of the second buoyancy means when viewed from above.
- 2. A high speed ship comprising a hull structure having a bow portion and a stern portion and being normally supported above the surface of the water at a design waterline when in operation, a forward strut depending from the bow portion of the hull structure subtended by a first buoyancy means, at least one aft strut depending from the hull structure at approximately midship, said at least one aft strut being subtended by a second buoyancy means whose beam is equal to or greater than its length extending laterally beneath the ship, the beam of said second buoyancy means being substantially equal to or greater than the full width of the ship, said at least one aft strut and said second buoyancy means providing more than 70% of the buoyancy for the ship during operation to maintain said hull structure above the surface of the water during operation and said forward strut and first buoyancy means providing 30% or less of the buoyancy of the vessel during operation; and wherein the center of buoyancy of the ship is located below the center of gravity of the ship and at least a portion of the second buoyancy means is located below the transverse line on which the longitudinal center of gravity of the ship is located.
- 3. The high speed ship as defined in claim 2 wherein said second buoyancy means is a swept shape in plan wherein the center of its leading edge is aft of the ends of its leading edge in the direction of forward movement of the vessel.
