ABSTRACT:
Inflatable or pneumatic float assembly has tough outer fabric tubular shell with an upper wall having a first elongated sleeve extending therealong to receive an elongated stiffening member. A lower wall of the float is stiffener by stiffeners to provide a step having an essentially upright transversely extending step wall. The float has a plurality of internal baffles which form inflatable compartments within the float, preferable to receive air filled bladders. The elongated stiffening member extending through the first sleeve has exposed portions to provide access for attachment means which cooperate with the exposed portions to permit the stiffening member to cooperate with an aircraft undercarriage. Wheels can be provided to permit the aircraft to be amphibious for landing on land as well as water, with various structures to permit changing relative positions of the wheels and the floats. Air pressure within the floats is such that the float provides a resilient suspension to provide a smoother ride when moving on choppy water or to resiliently mount the wheels in one wheeled embodiment.
