A buoyancy tank for a portable floatation apparatus which allows for the elevation of a watercraft above a water-line and which allows for the removal of the watercraft from a body of water. The buoyancy tank has at least one and/or a plurality of integrated cylindrical structures which supports the floatation apparatus in transport and storage. The integrated cylindrical structures provide sufficient support to allow the removal of the floatation apparatus by use of a boat lift and further provide sufficient support to allow a watercraft to be stacked on top of the floating apparatus while the floating apparatus is stacked on top of the floating apparatus for the purposes of storage. A plurality of said buoyancy tanks may be connected to the portable floatation apparatus by use of connecting means. The portable floatation apparatus should have a pumping device which pumps a sufficient volume of air into a plurality of the buoyancy tank which is effective to selectively and conveniently elevate a watercraft above a water line.

A lift raises and lowers a boat to load and unload the boat onto a roof of or a roof rack on a vehicle. The lift has an upper frame having a longitudinal axis, a lower frame having a longitudinal axis, and a linkage connecting the upper frame to the lower frame. In a first position the linkage is extended and the lift is raised and in a second position the linkage is retracted and the lift is lowered. At least one lift rack extends from or is part of the upper frame. The lift rack is adapted to support a boat at least vertically such that in the extended linkage first position a boat may be slid in a longitudinal direction between the lift rack and the roof or the roof rack of the vehicle. A method for using the lift is also disclosed.

The present invention concerns a handling system and method for use with a carrier vehicle or structure for unloading from, loading to and storing a smaller vehicle or body aboard the carrier vehicle or structure. The system includes a cradle for supporting a smaller vehicle or body therein. The cradle is mounted to a carrier vehicle or structure and is configured to be pivotable between a tilted position in which a smaller vehicle or body can be unloaded from or loaded into the cradle and a level position in which said smaller vehicle or body is stored aboard the carrier vehicle or structure. The system also includes at least one linear actuator for driving movement of the cradle between said tilted position and said level position.

An extraction vessel is provided that includes two pontoons forming parallel hulls, a cargo hold located between the pontoons, and a retractable extraction conveyor belt located between the pontoons and mounted on tracks so as to be movable between retracted and deployed positions. In the retracted position, a lower end of the conveyor belt is above the waterline of the vessel. In the deployed position, the lower end of the conveyor belt is below the waterline for extracting the floating debris, and an upper end of the conveyer belt is above the cargo hold to discharge the floating debris into the cargo hold. Also provided is an extraction vessel that includes variable buoyancy floats attached to the pontoons and movable between a raised position in which the lowest surface of the float is above the waterline, and a lowered position in which part of the float is submerged.

A trailer frame constructed from a polymer that cannot rust or corrode. The trailer employs a support plate that reinforces an inner and outer wall forming beams that includes a matrix of crisscrossed support walls. A top deck is releasably secured to the frame allowing refinishing of the trailer should the deck be damaged without replacement of the frame. Alternatively the top deck can be a foundation for an enclosure, shield, fence or any other known securement structures.

A loading and transport system is disclosed that engages with a transporting vehicle such as a hauler or semi-truck. The system includes a plurality of transporting components including platforms or compartments that are accessible independently for efficiently loading and unloading objects including vehicles or freight boxes.

A rotatable support structure for supporting elongate objects, comprised of a first support structure, a second support structure, a rotatable axle, a first hub, a second hub, a plurality of first elongate support members, an equal number of second elongate support members, and a locking mechanism, where the first support structure and the second support structure support the rotatable axle, the first hub is affixed to the rotatable axle and supports the first elongate support members, the second hub is affixed to the rotatable axle and supports the second elongate support members, corresponding pairs of the first and second elongate support members support elongate objects attached thereto, and the locking mechanism prevents the rotating axle from rotating and allows the rotating axle to rotate to allow the elongate objects to be conveniently loaded and unloaded from the rotatable support structure; whereby the rotatable support structure may be configured as a watercraft transportation trailer.
