A cover adapted to be reversibly attached over an opening of a storage compartment contained on a personal watercraft. The cover includes a generally planar substrate having formed therein a dry storage chamber and at least one additional feature selected from the group consisting of a cup holder, an equipment rail, a surround tray, an accessory mounting plate, and a magnetic surface.

A storage assembly for a vehicle has an outer compartment defined by an outer peripheral wall, an outer compartment lid operatively connected to the outer peripheral wall and moveable between an open position providing access to an interior of the outer compartment and a closed position blocking access to the interior of the outer compartment; and an inner compartment integrally formed within the outer compartment, the inner compartment being defined by an inner peripheral wall. The inner compartment comprises an inner compartment lid operatively connected to the inner peripheral wall and being moveable between an open position providing access to an interior of the inner compartment and a closed position blocking access to the interior of the inner compartment, and a sealing assembly for sealing the interior of the inner compartment when the inner compartment lid is in the closed position. A vehicle including the storage assembly is also disclosed.

A catamaran lifting apparatus is disclosed for lifting objects in a marine environment. The apparatus includes first and second vessels that are spaced apart during use. A first frame spans between the vessels. A second frame spans between the vessels. The frames are spaced apart and connected to the vessels in a configuration that spaces the vessels apart. The first frame connects to the first vessel with a universal joint and to the second vessel with a hinged connection. The second frame connects to the second vessel with a universal joint and to the first vessel with a hinged or pinned connection. Each of the frames provides a space under the frame and in between the barges that enables a package to be lifted and/or a marine vessel to be positioned in between the barges and under the frames. In this fashion, an object that has been salvaged from the seabed can be placed upon the marine vessel that is positioned in between the barges and under the frames.

An extender for holding boating accessories including at least a first limb and a second limb engaged in elbow relationship such that one can be pivoted with respect to the other about a transverse axis. At least one of the limbs includes a swivel portion that is able to turn about a longitudinal axis. At least one locking part moves longitudinally along a respective one of the limbs between locked and unlocked positions. When the locking part is in the locked position, it prevents the swivel portion turning.

A water-propelled or water-powered unmanned aerial vehicle including a base configured to carry a payload, and at least one nozzle attached thereto. The at least one nozzle is configured to selectively receive pressurized fluid from a source located remotely from the vehicle. The vehicle includes a control system configured to alter or otherwise selectively dictate the flow of fluid through the at least one nozzle and/or the orientation of the at least one nozzle with respect to the base in response to a received control signal for providing controlled unmanned vehicle flight.

An open water transport system for payloads and a method for transporting payloads. The system includes two sponsons substantially parallel to the other. The sponsons are spaced apart from each other and extending in a forward direction. A deck plate module is detachably mounted on top of each sponson. A superstructure may be detachably mounted to the deck plate modules. The superstructure may bear a weight of one or more payloads. The carriage assembly couples to the payload(s). The carriage assembly has an adjustment mechanism that permits an operator to redistribute the weight of a payload. The open water transport system is towed by another vehicle.

A sport board rack for improving the stowage of one or more boards on a power boat or other watercraft. The sport board rack can include one or more telescoping arms that can pivot independently relative to each other. Each of the telescoping arms can include a claw that can be extended and retracted to secure a board between the claw and two seats of the sport board rack. The claw can be rotated open to ease insertion of a board onto the two seats and rotated closed to secure the board between the claw and two seats when retracted.

A system for immobilizing a semi-trailer kingpin on a transport vehicle includes a balance arm and a substantially horizontal rigid linking structure designed to guide the vertical movement of the receiving nacelle, hold it in position above the lifting system in a horizontal plane and take up the forces exerted thereon. The longitudinal rigid linking structure is hingedly linked to the receiving nacelle and to the transport vehicle in order to take up the longitudinal forces from same, and the balance arm includes preloaded springs that take up the forces exerted on the balance arm when the receiving nacelle is temporarily inclined relative to the horizontal plane. The lifting system for lifting the receiving nacelle is mounted pivoting on the railway unit at a pivot pin transverse to the longitudinal axis of the transport vehicle.
