One example provides a floating drive-on pontoon port including a plurality of floating sections pivotally coupled together in series with one another to form an articulating port track base and an articulating starboard track base extending longitudinally in parallel with one another, the port and starboard track bases each having a lower surface to be disposed in water and an opposing upper surface to face away from the water. A port transport track extends longitudinally across the upper surface of the port track base, and a starboard transport track extends longitudinally across the upper surface of the starboard track base and in parallel with the port transport track, the port and starboard transport tracks each comprising a series of spaced apart rollers configured to respectively receive, transport, and support a port pontoon and a starboard pontoon of a pontoon during loading, unloading, and storage of the pontoon boat on the pontoon port. A lateral position of the port and starboard transport tracks relative to one another is adjustable to adjust a lateral distance between the port and starboard transport tracks to accommodate pontoon boats of different widths.

A self-sufficient launch device mounted to the body of a water vehicle that applies a pressing force to a surface to launch the vehicle into the water, comprising at least two force creating devices adapted to create the pressing motion required to launch the vehicle, an extendable and retractable rod that extends towards the surface upon activation, a contact pad connected to the rod that interacts with, and applies force directly to, the surface on which the vehicle is located, a power supply that enables the movement of the at least two force creating devices, and a control system adapted for remote operation of the device.

A boat lift assembly includes a first base member having a central beam portion and first and second sloped beam portions, and a second base member having a central beam portion and first and second sloped beam portions. The assembly includes a first plurality of roller tubes coupled to the first sloped beam portions of the first and second base members, and a first plurality of rollers disposed on the first plurality of roller tubes. The assembly includes a second plurality of roller tubes coupled to the central beam portions of the first and second base members, and a second plurality of rollers disposed on the second plurality of roller tubes. The assembly includes a third plurality of roller tubes coupled to the second sloped beam portions of the first and second base members, and a third plurality of rollers disposed on the third plurality of roller tubes.

An automated system is provided for moving a boat from a storage position in a boat garage to a deployed position in a dock channel. The system can include a boat trolley. The boat trolley can include a bottom frame that couples to and rides on rails of a track that extends between the boat garage and the dock channel. The boat trolley can also include an upper frame that with bunker supports for supporting the hull of the boat. The upper frame can be lifted off of the lower frame by a dock lift mechanism to thereafter lower the upper frame into the water, from which the boat can be deployed. Once done using the boat, the user can navigate the boat onto the upper frame, and the dock lift mechanism used to lift the upper frame and boat out of the water, the upper frame then dropped onto and coupled to the lower frame, and the boat trolley operated to move the boat from the dock to the boat garage for storage.

A system for conveying a barge over a levee in a level attitude providing for safety and avoidance of damage to the barge, the levee, and of persons, where a barge is to be conveyed from a waterway, over a levee, through a floodgate in a floodwall, and into a maintenance building, and the reverse operation, by placing a barge in a drydock, resting on support blocks, aligning the drydock with the floodgate, placing level-raising tractors with tractor controllers underneath the barge, raising the barge off of the support blocks, and rolling and lifting the barge over the levee while keeping the barge in a level attitude, optionally under the additional control of a person using a hand-remote tractor controller.
