Abstract: An apparatus is disclosed for propelling a person in an underwater environment. The apparatus includes a hull assembly for maintaining the apparatus at the desired level of buoyancy, the hull assembly having a longitudinal axis. Support means are provided for allowing the person to position the hull assembly at the desired angular orientation relative to himself. Thruster means are connected to the hull assembly for propelling the apparatus through the water. The thruster means are positionable at the desired angular orientation relative to the longitudinal axis of the hull assembly. The hull assembly is angularly oriented independently of the direction of the movement of the apparatus. Means are provided for connecting the thruster means to the hull assembly.
