FIELD: shipbuilding; designing surface displacement-type ships.
SUBSTANCE: proposed ship has at least two interconnected hulls. Each hull has outer and inner envelopes. Outer envelope of each hull is made in form of body of revolution or combination of bodies of revolution having common axis of rotation; they are provided with paddles located on envelope generatrix. Outer envelope is so mounted relative to inner one that it should rotate under action of counter flow of water.
EFFECT: reduction of total resistance of water to motion of ship at varying running speeds.
