Abstract
A high performance amphibious vehicle which includes a conventional hull, modified to mount a single steerable front wheel and two hydraulically driven rear wheels. The wheels are retractable between elevated positions above the hull waterline and lowered positions located below the hull. The rear wheels are powered by individual hydraulic motors that are connected to a pump in the hull, via hydraulic hoses that are routed through hollow tubular levers that support the wheels for adjustments between the retracted and lowered positions.
