ABSTRACT:
A buoyant boat hull of an amphibious vehicle has concave, quarter cylinder recesses along the sides down from the waterline, such recesses receiving the upper inboard quadrants of helical augers. The recesses confine water between the screw threads and project it directly to the rear for more efficient forward thrust. The engine and pumps for the hydraulic motors are mounted on a slide to be moved forward and aft as desired to shift the center of gravity and aid in transition between land and water travel.
