FIELD: shipbuilding.
SUBSTANCE: invention relates to shipbuilding, namely to high-speed displacement vessels moving on water surface and under water. To create active water flow along longitudinal sides of ship hull by means of ship power plant along ship hull longitudinal recesses of paired, sections of concave section symmetrically arranged relative to ship centerline plane in the form of curve articulated oval surfaces. Active water flow is created by means of side propellers arranged inside paired symmetrically located longitudinal recesses of concave section in front third of ship hull length, wherein active water flow along longitudinal surfaces of ship hull from side screw propellers is swirled in opposite directions relative to ship centerline plane.
EFFECT: higher ship speed.
