Rubber is a widely used material for corner dock fenders due to its outstanding shock-absorbing properties. Rubber fenders are known for their durability and resilience, making them ideal for high-impact situations. They can withstand harsh marine environments, including exposure to UV rays and saltwater, which can degrade other materials over time. Additionally, rubber corner dock fenders provide a high level of energy absorption, reducing the risk of damage to both the dock and the vessel.

However, rubber fenders do have some drawbacks. One significant issue is that they can leave black marks on the hulls of boats, which may be undesirable for some boat owners. Furthermore, while rubber fenders are generally robust, they can be prone to wear and tear over time, especially if not properly maintained. Regular inspections and maintenance are essential to ensure the longevity of rubber corner dock fenders.

In contrast, PVC (polyvinyl chloride) is another popular material for corner dock fenders. PVC fenders are lightweight, easy to install, and resistant to various environmental factors, including UV radiation and moisture. They are often used in applications where aesthetics are important, as PVC can be manufactured in various colors and finishes. Additionally, PVC dock fenders do not leave marks on boat hulls, making them a preferred choice for many boat owners.
