(RIB) with an outboard petrol (gasoline) engine. It is equipped to inflate and deflate itself as it runs. When submerged it seals its engine and runs with battery-electric thrusters, which are on a rotatable cross-arm, and is deflated. Thus it transforms between a fast light surface boat and a submerged diver propulsion vehicle. The central box contains the pump to deflate and inflate the tubes, and a miscellaneous kit.
