FIELD: transport.

SUBSTANCE: invention relates to design of sport motor boats. Sport motor boat consists of body, engine compartment with engine, pilot cockpit and fairwater piece. Boat's body is made as frame located above water. At both sides of frame, at least two pairs of front and rear wheels-floats respectively are freely installed on axes. Wheels-floats volume is filled with ultralight waterproof material for example with foam plastic. Cockpit with pilot and engine compartment with engine are spaced along frame length with common centre of gravity in the central area of distance between axes of wheels. Rear wheels are provided with coaxial with them disks. Outer diameters of disks exceed diameters of wheels. In the area of front wheels location, retractable device is installed on the frame. The device is made as disk sector with rotation plane perpendicular to axes of front wheels. Bottom edge of disk sector in lowered position is spaced from axes of front wheels for value of rear wheels coaxial disks radius.

EFFECT: reduction of hydraulic resistance in motion, higher speed and safety during motor boat control.
