ABSTRACT:
A multi-pontoon amphibious vehicle with an improved track securement and guide means for the track to prevent "track throw" or loss and minimize wear while operating at speeds of up to twenty miles per hour. The vehicle includes two spaced-apart parallel pontoons joined by a centrally located operator's platform structure, with each pontoon having a moveable endless cleated track for propulsion, with the track supported on its pontoon by fore and aft multiple sprocket wheel sets and a series of larger bogie wheels at its botton and guides at its top. Each track comprises a parallel set of continuous endless belts carrying a series of laterally disposed cleats with drive lugs, which lugs are engaged by the teeth of four sprockets wheels per track.
