SUBSTANCE: stern of vessel with blade paddle wheels is made as two through water-flow channels dividing bilge into three water displacing sections. On vertical walls of water-flow channels bearings of two driving shafts with paddle wheels are installed. The paddle wheels consist of two parallel to each other solid disks with blades installed between them which blades are located on several heterodistant diameters. When wheels are rotating the blades move one after another in groups decanting water on more distant from shaft blades ensuring bumpless entrance in water at an angle of 45 degrees for them. At an exit from water, angle of blade inclination to horizon ensures accelerated water discharge under water for them.

EFFECT: creation of vessel with propulsor having large hydraulic cross-section ensuring bumpless entrance into water, absence of wave at an exit from water, creation of large support for vessel both in deep water and draft is restricted, possibility to use impact pressure of water counter flow.
