FIELD: transport.
SUBSTANCE: displacement ship has bottom cavity making the wavy profile starting from fore step and limited by skegs on boards and aft outline as inclined plate. Recess chamber is connected with higher-pressure air source and accommodates lengthwise keels limiting the air transverse motion and crosswise inclined plates arranged in downstream line. Plate is arranged behind the step at node part to turn, at lowering or lifting its front edge, around axle directed across the bottom, coupled with plate and secured at recess bottom. Plate length in flow direction makes the magnitude at plate turn about axis makes the bottom surface ahead of step with bottom surface inside said recess to prevent separation flow there behind. Said plate can limit lowering of its front edge to ship bottom level in the step area. Said transverse inclined plates can be opened to working position and folded to abut on the bottom.
EFFECT: enhanced performances.
