he design of a D-type rubber fender is integral to its performance. The classic "D" shape, with its rounded face and flat back, allows the fender to absorb energy efficiently while maintaining a low profile. This profile is specifically engineered to provide energy absorption and the risk of damage to both the vessel and the docking infrastructure.

The geometry of D-type fenders is carefully crafted to distribute the impact force over a wide area. The rounded face ensures that the force of the vessel’s impact is absorbed gradually, while the flat back allows for a secure fit against the dock or pier, preventing the fender from shifting under load. The fender's size and thickness are tailored based on the size of the vessels being docked and the expected impact forces.

Manufacturers also pay close attention to the surface texture of the fender. Some D-type fenders come with smooth surfaces, while others are designed with textured or grooved surfaces to improve friction and ensure better gripping when the vessel comes into contact with the fender. This can help prevent slippage, particularly in high-traffic areas or in rough seas.
