HIGH-SPEED CATAMARAN Russian patent published in 2016 - IPC B63B1/12 B63B1/10 

FIELD: ship building.

SUBSTANCE: invention relates to ship building, mainly river one, and can be used to create high-speed passenger ships. Two-hull vessel comprises two hulls interconnected by a connecting bridge. Hulls in the plan have the shape of a flat-convex wing with flat external side surfaces and are made of a rectangular cross-section. Underbottom the interhull space over its entire square is overlapped by a horizontal plane having in the longitudinal cross-section the shape of a flat-convex wing with a flat bottom surface.

EFFECT: use of the invention allows to reduce wave impedance and, hence, to increase the catamaran speed.
