Boat fenders are protective devices that are placed between a boat and a dock or another boat to prevent damage caused by impact.

Boat fenders are typically made of durable rubber, foam, or plastic, which can withstand the force of impact and prevent damage to the boat's hull.

Boat fenders should be attached securely to the boat using fender lines or clips, ensuring they are positioned correctly to provide maximum protection against impact.

The appropriate size and shape of boat fenders depend on the size and type of boat, as well as the intended use and water conditions. Cylindrical, spherical, and rectangular fenders are available in various dimensions, allowing for customization based on individual needs.
