An amphibious vehicle for transiting deep or shallow waters and/or the fu ll range of wetland and dry soil environments, consists of a box-like struct ure with buoyant tracks that are powered to move around the structure. The b uoyant tracks encircle the vehicle's length and extend laterally for a subst antial portion of the vehicle's width or beam. When operating in water the b uoyant tracks provide a majority of the buoyancy keeping the box-like struct ure above water surface or its tracks can be flooded to submerge the vessel. The amphibious vehicle can transport heavy equipment and personnel from shi ps located offshore, across undeveloped beaches, to positions ashore.</SDOAB >
