The invention relates to shipbuilding and can be used in reconditioning in order to economize fuel and to increase speed. The technical problem is solved by the shipboard installation of air compressors, air receiver tanks, pass valves, air conduits, air separating conduits, air intakes and air injectors, which are interconnected by air ducts. An air separating conduit is mechanically secured in the bow of the ship and has air injectors secured along the centre thereof up to the stern. The injectors direct a jet of air backwards so that the jet of air thrusts the ship forwards, then the air rises along the sides of the ship, maintaining a layer of air between the ship and the water, thus reducing water resistance. The injectors in the bow direct a jet of air such that the ship is constantly sailing into an air space.

A pneumatic ship and a pneumatic ship system are provided. The pneumatic ship includes a floating body which is suitable for floating on a water surface and a pneumatic propulsion device arranged on the floating body, wherein the pneumatic propulsion device is suitable for forming airflow to generate a propulsive force, so as to push the floating body to move. Technical solutions of the present invention have a higher flexibility.

A hovercraft assembly includes a vehicle that may be driven. A pair of propulsion units is provided and each of the propulsion units is coupled to the vehicle. Each of the propulsion units may urge air outwardly from the body. Thus, the vehicle may levitate with respect to support surface. Each of the propulsion units may direct the air in a selected direction with respect to the body. Thus, the propulsion units may urge the vehicle along the support surface in a selected direction. Each of the propulsion units is operationally coupled to the handlebars such that the handlebars control operational parameters of each of the propulsion units.
