An adjustable attachment device includes an elongate body defining a plurality of openings and an attachment bracket attached to and slidable relative to the body and defining an opening. The adjustable attachment device selectively and adjustably interconnects a fixed piling and a floating dock assembly. A fixed attachment device includes a main portion defining an opening and a generally triangular end portion defining an opening. The fixed attachment device rigidly interconnects a fixed piling and a floating dock assembly. A bumper attachment device includes a first and second end portions defining openings and a rotatable bumper. The bumper attachment device is connected to a floating dock assembly.

A fender mounting assembly includes a backing plate and a branch. The backing plate is configured to attach to a slip wall to mount the fender mounting assembly to the slip wall. The branch is configured to hold a fender a predetermined distance away from the slip wall. The branch extends from the backing plate and includes a first section and a second section. The first section has a first end and a second end. The first end is attached to the backing plate. The second section has a third end and a fourth end. The third end is attached to the second end of the first section. When the fender mounting assembly is attached to the slip wall in an upright position via the backing plate, the second section of the branch extends downwardly from the first section of the branch.

A frame rail assembly for a boat dock structure includes a frame rail member and a removable resilient rub-rail member. The frame rail member includes a first side configured for securing the frame rail member to a side of the boat dock structure; a second side opposing the first side; a first channel extending along a length of the frame rail member; and a second channel below the first channel, the second channel extending along the length of the frame rail member. An interlocking frame rail system for boat dock structures includes a first frame rail member, a second frame rail member, and an upper connector member extending along at least a portion of a length of the first frame rail member and at least a portion of the length of a second frame rail member.

A docking system to aid in docking a boat includes an elongate member that engages the dock and a distal end extending into the body of water away from the dock. A line having configured to attach to the beach or walkway is connected to a distal end of the elongate member. A first connecting assembly, including a first line that is releasably securable to the dock and a float secured to a distal portion of the first line, engages a distal portion of the elongate member. A second connecting assembly comprising a second line is releasably securable to the dock. At least two elongate floats are secured to the second line. The second connecting assembly is connected to the float of the first connecting assembly, and the second connecting assembly is longer than the first line.

The present disclosure describes a resilient bumper that comprises an arc-shaped spring member that extends from a first end to a second end along a spring axis and includes an impact surface arranged between the first and second ends; and a support member that includes an attachment interface that extends in parallel to the spring axis of the spring member and is configured to releasably engage the first and second ends of the spring member. A bumper system and a marine structure are also described.

Reinforcing layers each have a cord angle set to 25° or greater and 45° or less when a body is in a neutral state. When the body is loaded with a specified internal pressure, intermediate rubber layers disposed between adjacent sets in which cords of the reinforcing layers extend in an intersecting direction are shear-deformed, the cord angle increases approximately to a stable angle of repose, and the expanded body maintains a predetermined shape. In each of the sets being formed of two reinforcing layers layered adjacently, the cords of the reinforcing layers extend in an identical direction at the predetermined cord angle. Since substantially no shear force acts on the intermediate rubber layers disposed between the reinforcing layers, the resistance when expanding the body decreases. This provides a pneumatic fender that expands more smoothly and ensures a predetermined shape when a body is loaded with a specified internal pressure.
