A dock shock absorption device includes a frame and one or more energy dissipative elements. The frame is attached to a dock with the frame enclosing a pylon. The one or more energy dissipative elements attach to the frame and are equal to or less than 1 inch from the pylon.

A modular floating platform connector includes a connecting unit with a hollow center chamber that has one or more inside diameters. The chamber may have wall surfaces to secure components to modular floating platforms. The connector may further incorporate one or more external features such as a collar and retaining ribs that engage with the connecting tabs on modular floating platform float modules to securely hold the float modules together and to retain attachment members of accessories, fixtures, structures and other components to modular floating platforms.

An element for use in a watercraft is provided comprising a first rotatable support member mounted on the element such that the position of the first rotatable support member relative to the element can be varied by a user. A floating dock comprising at least one element is also provided.

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.

An inflatable vessel is provided, the vessel comprising an enclosed flexible membrane having an interior, a first end and a second end; and a rigid elongate member extending within the interior of the membrane and attached to the membrane at a first attachment point at the first end of the membrane and to the membrane at a second attachment point at the second end of the membrane. The vessel finds use, for example, in a floating dry dock assembly.

A boat lift is attached to piles driven into the earth or to another object. The boat lift is held in horizontal position relative to piles or the object to which it is attached, but vertical movement of the boat lift relative to the object is permitted. The boat lift is connected to the piles by modular units or cube constructs that have a post extending there through. The post has a blade extending from it. The blades are attached at an angle, according to the application, to pile guides that engage piles. The pile guides vertically traverse the piles, permitting the boat lift to move vertically relative to the object, but fixing the horizontal position of the boat lift.
