FIELD: transport.;SUBSTANCE: invention relates to aircraft engineering, particularly, to hydro-airfoil boats. Proposed hydro-airfoil boat comprises airframe including submersible body, tapered thick wing, wheel-ski undercarriage, lift-sustainer jet engine, nozzles-elevens, boundary layer control gas-dynamic system, takeoff-landing device, hunting gas rudder, wing center-section, flashing beacon lights, and tie-down rope lock. Airframe represents a wide-body low-wing plane. Airframe legs-pylons support catamaran ski-floats with wheels of main legs. Nose parking ski-step is arranged ahead of wheel while tail steering ski, a course stabiliser, is mounted behind the wheel.;EFFECT: better hydrodynamic navigability.;3 dwg
