High speed catamaran craft useful for pleasure craft or customs launch

摘要

The craft comprises two hulls with their stems situated asymmetrically so their inner surfaces (7, 8) form a convergent forward end to the tunnel (3) between the hulls. The air flow through the tunnel increases the aerodynamic/hydrodynamic interaction, reducing the craft's drag and increasing its lift, so that it is capable of higher speeds. Each of the craft's hulls is divided by sealed bulkheads into three separate compartments of different volumes, which make it unsinkable.
