A device that can be easily and releasably fixed, moved, and reattached in any desired location on a boat; and provides for the easy attachment and securing of multiple ropes or other fastening means, at the same time, which are then attached to a single or multiple boat fender(s) or other floatation device(s) to facilitate the proper placement and location of the boat fender(s) or other floatation device(s) in relation to the boat, as needed, in that location.

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 cassette assembly is disclosed attachable to an end portion of a waterborne vessel and including a cassette section to bear against an external structure in use. The cassette section is movable relative to the vessel in a direction towards an opposite end of the vessel. A resilient buffer system counters movement of the cassette section when the vessel is moved towards the external structure, wherein the resilient buffer system includes a buffer including a plurality of resiliently compressible elements arranged in series. A waterborne vessel includes a receiving portion for receiving the cassette assembly, and can be used to service a water-accessible structure such as a wind turbine.

Fender arrangement for docking a marine vessel (1) with a boat landing (2) of a marine offshore structure (3) such as a wind power plant, including at least one fender unit (12, 13) composed of elastically deformable material and provided with a receiving recess (18) for a docking rail (5) of said boat landing (2). The fender arrangement is especially characterized in that fender unit (12, 13) exhibits an internal deformation control cavity (20) positioned at a distance from the receiving recess (18) within the fender unit (12, 13) and extending at least along the width of said receiving recess (18), controlling deformation of the fender unit (12, 13) into forming a gripping hold of a docking rail (5) by compression of the internal deformation control cavity (20) when the fender unit (12, 13) is pressed against the docking rail (5).
