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.

A suctioning watercraft fender attaches to a watercraft while the watercraft is in a mooring state. The watercraft fender may couple a first watercraft to a second watercraft or a first watercraft to a fixed surface. The watercraft fender includes a body defining a longitudinal axis, wherein the body includes first and second opposing ends. The fender further includes a first coupling member coupled to the first end of the body. The first coupling member includes a first suction cup and a first pressure mount actuatable to selectively lock or release the first suction cup from a first surface.
