A boat lift has pumps that evacuate water from flotation containers lower the boat lift. Multiple flotation containers are retained by a frame that is formed as a grid. The pumps are contained within a housing that is retained in position by the frame. Water enters the housing through valves and is distributed to the flotation containers to lower the boat lift. Water is evacuated from the flotation containers by pumps, with valves closed to prevent water from entering the flotation containers.

Disclosed herein is an inflatable watercraft barrier in one example having an inflatable perimeter tube. Also disclosed is a diaphragm sealed to the perimeter tube to form the watercraft barrier between a watercraft and the water in which the watercraft barrier and watercraft float. In one example, a portion of the perimeter tube forms a gate portion which is at least partially selectively deflated so as to be denser than water, and therefore rotates about a gate pivot such that the watercraft may enter the watercraft barrier through the gate portion. Also disclosed is a water pump in fluid communication with the watercraft barrier so as to evacuate water from between the watercraft barrier and the watercraft.

A boat lift has one or more pumps that evacuate water from a first flotation tank construct and a second flotation tank construct to create flotation of the boat lift. Modular boat lifts may be constructed according to the invention that have substantial size but are transportable by truck for construction on site.

A method comprising scanning at least one portion a hull of a vessel positioned below a waterline while the vessel is floating in water. The method further comprises generating multi-dimensional scans of the at least one portion of the hull based on data acquired during the scanning, generating a 3-dimensional (3D) model of the at least one portion of the hull, analyzing the 3D model to identify one or more features of the hull of the vessel below the waterline, generating docking information for drydocking the vessel based on the one or more features of the hull, and identifying, based on the generated docking information, a docking plan for supporting the vessel when the vessel is supported out of the water. The method further comprises outputting instructions to dry dock the vessel.

A device for rapidly remotely coupling together two vessels, in particular a first ship or floating support and a second ship, comprises: at least one floating and docking structure fastened to or suitable for being releasably fastened to the side and/or the keel of the hull of a second vessel; and at least two actuators spaced in succession from one another in the longitudinal direction of the first vessel. The actuator cylinder of each the actuator is arranged to be fastened to the side of the hull of the first vessel, using a first fastener and pivot hinge device. The end of the rod of each actuator is arranged to be fastened to or suitable for being fastened to the floating and docking structure via a second fastener and pivot hinge device.
