ABSTRACT:
An auger-driven remotely controllable amphibious vehicle is disclosed. The vehicle includes a buoyant hull in the general configuration of a speedboat. An auger is mounted for rotation along each side of the vehicle. The generally cylindrical augers with helical screws are nested closely in approximately quarter-cylinder recesses formed along the lower sides of the hull at the waterline so that a considerable portion of the water moved by the augers is contained in the narrow spaces between the augers and the hull, and is then thrust directly rearward (or forward) for increased efficiency in propulsion. A propulsion mechanism and other components are preferably mounted in the center of the vehicle for balance. The vehicle preferably includes control apparatus and signal receiving apparatus for remote operation.
