AIRCUSHION CRAFT

PURPOSE:To restrain the pitching of a hull, by providing a pressure adjusting means for adjusting the air-cushion pressure of front and rear aircushion parts, individually in accordance with the vertical motion of the sea level. CONSTITUTION:An aircushion section is divided into two front and rear aircushion parts 8a, 8b by means of a skirt 5. Further, air supply opening sections 4a, 4b for supplying aircushion air into the aircushion parts 8a, 8b are formed in the bottom 11 of a hull 10 in the aircushion parts 8a, 8b, respectively, and are connected to an air supply device disposed in the hull 10 so that cushion air fed from this supply device is jetted in the direction indicated by the arrow 6. Further, the cushion pressures in the front and rear cushion parts 8a, 8b may be individually adjusted by a pressure adjusting means mounted on the hull 10.
