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.

A control system for a suspension system of a multi-hulled vessel, the vessel including a chassis portion, at least two hulls moveable relative to the chassis portion. The suspension system of the vessel provides support of at least a portion of the chassis above the at least two hulls, and includes adjustable supports and at least one motor to enable adjustment of a support force and/or displacement of the adjustable supports. The control system includes a fender friction force input for receiving at least one signal indicative of a friction force on a fender portion between a fixed or floating object and the vessel chassis portion, and in response to the fender friction force input, the control system is to adjust the support force and/or displacement between the chassis portion and the at least two hulls to reduce or minimize the friction force on the fender portion.

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.

Marine fender (1) for engaging an offshore structure (10) during a transfer operation. The fender (1) comprises a mount (3) for fixing the fender (1) to a vessel (5). An engagement part (2) engages with an opposing surface (11) of the offshore structure (10) when the vessel (5) and opposing surface are forced together such that interface friction resists movement of the engagement part (1) over the opposing surface (11). A coupling (4) is provided connecting the engagement part (2) to the mount (3), wherein the coupling (4) comprises a regulating part for regulating the velocity of movement of the engagement part (2) over the opposing surface (11).

A boat fender hanger is an apparatus used to hold a fender alongside a boat in order to protect the boat while docking. The apparatus includes a hanging mechanism, a fender-retaining sleeve, and a suspension band. The hanging mechanism is used to readily attach and detach the apparatus from the side of a boat. The fender-retaining sleeve is used to secure a fender within the apparatus. The suspension band is used to position the fender-retaining sleeve offset from the hanging mechanism in order to prevent the hanging mechanism and the fender-retaining sleeve from functionally interfering with each other.

A planning boat includes at least one tank provided on a bottom of the boat. The tank has, at a stern side, a wall through which a through hole is provided below a waterline. A hull of the planning boat includes a bottom plate that forms the bottom of the boat, right and left side plates that form sides of the boat and a bow, a transom plate that forms a stern, and a plurality of longitudinal vertical plates. The plurality of longitudinal vertical plates each extend between the transom plate and forward portions of the side plates along a sailing direction and each have a lower surface that is fixed to an upper surface of the bottom plate. The tank is formed by using the pair of longitudinal vertical plates of the existing planning boat.

A fender hanging device may include a back plate coupled to a first arm and to a second arm. A cavity may be formed between the back plate, the first arm, and the second arm. A channel may separate the first arm and second arm. An upper limiter may be coupled to the back plate opposite the first arm and second arm, and a block aperture may pass through the upper limiter. Optionally, a flexible linkage having a body with one or more linkage fasteners coupled to the body. A fender retainer may be coupled to the flexible linkage, and the fender retainer may have an annular frame. A fender may be coupled to the annular frame, and the fender may be movable between a first position, a second position, and/or any number of other positions.
