ABSTRACT:
An amphibious vehicle capable of high speeds on the water has a buoyant hull with driven tracks on each side of the hull. The tracks are movable between an upper position and a lower position relative to the hull. The tracks propel the vehicle both for land travel and water travel. Water diverter vanes at the aft end of each track divert water being carried forward by the tracks. Water diverter vanes at the forward ends direct water carried on the upper runs in a downward and aft direction. A cavitation plate is located behind each of the tracks while waterborne and below the waterline of the hull. A tiltable transom flap is attached to the transom and extends rearward.
