FIELD: the invention refers to shipbuilding and applies to designing a hull for example of an underwater speedy apparatus of cylindrical or cigar-shaped form and with reduced resistance of water to their translational movement.
SUBSTANCE: the non-watered hull is provided with channels for supercharging gas. The body is fulfilled in kits from needle-shaped elements with keeping after fixing these elements between themselves channels for supercharging gas with the aim of receiving stable bubbles of gas. The essence of the invention is in that reducing friction of water is achieved by maximum reducing of the value of moistened surface of the hull due to creation of a thin gaseous film-layer out of stable gas bubbles on the exterior surface of the hull. At that the water will slip on the surface of gas but not of the hull.
EFFECT: increases effectiveness of reducing water resistance to the movement of the hull of a water transport vehicle.
