Rubber or wooden bumpers of various types that are used on docks at the point of contact between the vessel and the dock are called fenders and prevent damage to them at the point of contact. Some types of fenders can also be used as hulls of vessels and ships. Fenders or bumpers prevent direct collision of two rigid objects.
