The invention discloses a novel supercavitation water surface high-speed boat. The novel supercavitation water surface high-speed boat comprises submerged bodies 23, a support structure, a turbojet engine 8, a driver cabin 5, a steward cabin 4, an S air inlet channel 7, a tail flame treatment nozzle 9, a power source system 1, a central control system 6, an air filter device 2, an air compressionsystem 3 and cavitation generators. The cavitation generators each comprise a cavitator 10, air guiding bushings 13, exhaust holes 14 and air leading grooves 16. Air enters a hull from the air filterdevice 2 and enters the turbojet engine 8 through the S air inlet channel 7 and is finally ejected out through the tail flame treatment nozzle 9. The novel supercavitation water surface high-speed boat takes the turbojet technology as propulsion power, so that compared with an underwater propeller, the propulsion speed and the efficiency are higher; the cavitation generators adopt the supercavitation technology, so that the hull does not make direct contact with water, compared with a traditional vessel, the water resistance of the hull can be reduced, and the navigational speed is increased.
