Provided is an automotive amphibian trailer assembly. The assembly includes a trailer for being towed by a vehicle, and upon which the vehicle can be loaded. Further, the assembly includes inflatable means for inflating to float the loaded trailer on water. Advantageously, the inflatable means may be releasable from the trailer so that the trailer can be readily used for purposes other than carrying the vehicle (e.g. carrying soil) and/or made more compact for storage (e.g. in a home garage).

A system is provided that includes a boat; a pair of wheels; for each wheel, an arm to which said each wheel is rotatably mounted, the arm being movable between towing and water configurations. In the towing configuration, the boat is supported for rolling movement on the wheels when dragged from the bow of the boat. In the water configuration the wheels are alongside the boat; and means for coupling the boat to a vehicle, such as a hitch are provided.

Mobile pontoon and ferry crossing equipment as well as a pontoon and a ferry accompanying this equipment, whereas crossing equipment comprises at least one foldable ferry or one foldable pontoon, each of which has a compact modular design composed of float modules and equipped with self-aligned joining elements that stabilized these modules, according to the invention is characterized by the fact that the foldable ferry (1) or foldable pontoon (2) in its closed condition for transportation forms a semi-trailer or a trailer, whose self-supporting chassis (3) is at the same time a basic float module of the foldable ferry (1) or foldable pontoon (2) respectively.

An amphibious transport apparatus includes forward and aft ends, a pair of spaced apart pontoons including tracks, and a transversely extending structure, which can include a platform, that spans between the pontoons and connects the pontoons together. The amphibious transport apparatus further includes a sled vessel that can be used to transport materials or personnel. The sled can be releasably attached to the amphibious transport apparatus with tow bar and a pivotal connection. Said tow bar can be rotatable between an upper storage position wherein the tow bar engages the vessel away from said pivotal connection and above a terrain surface, and a lower towing position. A towing position of said amphibious craft and sled can be defined by the sled connected to the amphibious craft at the releasable pivotal connection, with the amphibious craft being self propelled with said tracks for engaging the underlying terrain and with the sled in the lower towing position so that the sled bottom drags along on the underlying terrain during movement of the amphibious transport apparatus and sled. A trailer for loading and unloading the sled can also be provided. The amphibious craft can push the sled onto the trailer during loading.

The present invention provides an amphibious mobile system adapted to provide comprehensive digital learning facilities in remote areas. The system further comprises a touch screen display on the amphibious vehicle. The system further comprises a processor configured to communicate with the display and receive user input on the display. Data gathered via user inputs is compared against the metrics of emotional expression of interest gathered by the camera. The system further comprises a location sensor on the amphibious vehicle configured to determine a geographical location of the vehicle and configured to communicate the location to the processor. The processor is configured to communicate with a database before determining the type of information that is relevant to the specific location of the amphibious vehicle. The system may comprise the database. Alternatively, the system may further comprise a network communication module on the vehicle, in communication with the processor. The network communication module is configured to allow the processor to communicate wirelessly with a network device at a location that is remote from the amphibious vehicle.

A boat ramp designed to collapse so the amphibious vehicle may be towed at highway speeds. The ramp fabricated of a central isosceles triangle hinged to the vehicle at its base flanks a pair of right triangles hinged along their hypotenuses such that the ramp can be folded over the vehicle during travel. The hinged portion is reinforced with removable steel channel during use.

An offroad utility vehicle comprises a carrier deck, a demountable platform that is movable between a mounted position in which the demountable platform is carried by the carrier deck and a demounted position in which the demountable platform is deployed onto the ground. The offroad utility vehicle includes a hook and lift mechanism for moving the platform between the mounted and demounted positions. The hook and lift mechanism comprises a hook for hooking onto the demountable platform. The hook and lift mechanism comprises a power lift mechanism that includes an actuator and a rotatable frame for rotating the demountable platform into an inclined posture relative to the carrier deck. Alternatively, a drop-leg mechanism may be used to deploy the demountable platform.

A watercraft having a frame which incorporates rails and a plurality of sleeve members. The rails may be used to increase modularity of the watercraft and increase the surface area for attachment of accessories and may be comprised of modular aluminum extrusion. The sleeve members may be used to attach a variety of accessories for recreational watercrafting or for fastening the watercraft to a trailer.
