ABSTRACT:
An amphibious vehicle has a watertight vehicle body and at least two elongate buoyancy tanks, with a mechanism for displacing the buoyancy tanks between operative positions, in which the buoyancy tanks extend parallel to opposite sides of the vehicle body, and inoperative positions, in which the buoyancy tanks extend parallel to one another along the top of the roof of the vehicle body. A pair of propulsion units can be lowered from the vehicle body for supporting the vehicle during travel into a body of water and for propelling the vehicle through the water. Each propulsion unit comprises an elongate body, propellers in a duct extending longitudinally through the body and side openings from the duct to permit steering by rotation of the propellers.
