An enhanced system for controlling boat fenders wherein, based on a tidal range chart, a motion function is calculated for one or more boat fenders, which is loaded into a fender controller so that fenders are lifted or lowered to protect a boat over a period of time as boat rises and falls with water levels when stationed at a dock.

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.

A cord angle of reinforcing layers having a bias structure constituting a body portion is set to 25° or more and 45° or less in a neutral state of a body. Reinforcing layers are bonded with a bonding member interposed between the reinforcing layers, the bonding member disposed in a space between the reinforcing layers facing in the cylinder axial direction of the body portion and a hemispherical portion. The layered bonding members have the same bias structure as the reinforcing layers of the body portion. A cord angle of the bonding member is set to ±10° of the cord angle of the reinforcing layers of the body portion. The spaces have a plurality of different sizes. One set of ends of the spaces are set to a plurality of different positions, and the other set of ends are also set to a plurality of different positions.

Described are ships and docking systems comprising a fender for mounting on a bow of a ship, comprising an elastically deformable body portion, and a concave engagement surface defined by the body portion, wherein the concave engagement surface extends perpendicular to a center line of the ship, such that portions of the fender distal to the center line extend further forward in a direction parallel to the center line than a portion of the fender central to the center line.

A protective fender for a watercraft includes a plurality of attachment mechanisms configured to secure the protective fender to an exterior portion of the watercraft. The protective fender further includes a fender body, wherein a first surface of the fender body that contacts the exterior portion of the watercraft comprises a smooth surface. The protective fender also includes a plurality of adjustable-length straps. A first adjustable-length strap secures an upper-left quadrant of the fender body upwards to a first attachment mechanism of the plurality of attachment mechanisms, and a second adjustable-length strap secures an upper-right quadrant of the fender body upwards to a second attachment mechanism of the plurality of attachment mechanisms.
