Abstract : There is presented in combination, a water vehicle and a directional control means therefor. The water vehicle includes at least a portion thereof which is underwater during travel of the vehicle through water. The directional control means comprises a plurality of symmetrically disposed arms extendible from sides of the underwater portion of the vehicle. The arms each include a multiplicity of fins in a compact array for contact with the water through which the vehicle portion moves, each of the fins having an uncambered, neutral lift cross-section matching the hydrodynamic streamline flow thereabout at predetermined vehicle speed below the cavitation threshold.
