Abstract: The main rotor (1) located at the bow (3) of the hull (4) is transverse to a vertical plane through the axis of the hull and consists of two or more units of cylindrical wheels (5), which are equipped with blades (17). Each unit of cylindrical wheels (5) is provided with its own independent braking device (13). Longitudinal channels (30 and 31) are made on the bottom (29). These channels have different cross-sections along the axis of the hull. To be more precise, their cross-sections decrease from bow (3) and stern (32) to the bottom center (29). Secondary propelling and maneuvering devices consist of secondary rotors (2), water-jets or similar components which are housed on the bottom (29) in pairs of two.
