Abstract
An improved amphibious craft having a hull having spaced apart pontoons is fitted with belts and cleats. A platform is connected to each said pontoon. A plurality of bogie wheels are connected to each pontoon. One or more belts encircle each pontoon. Drive and guide lugs are attached to each of the belts having drive lugs positioned on opposing sides of each bogie wheel. The drive and guide lugs help center the tracks/belts relative to the bogie wheels. A plurality of polymeric cleats of special configuration are attached to the belts and drive lugs with fasteners. Each cleat has a central longitudinal axis. Each cleat has a center pad, a pair of spaced apart end pads and diagonally extending channels, spaces, or gaps in between each end pad and the center pad.
