In boating, a fender is a bumper used to absorb the kinetic energy of a boat or vessel berthing against a jetty, quay wall or other vessel. Fenders, used on all types of vessels, from cargo ships to cruise ships, ferries and personal yachts, prevent damage to vessels and berthing structures.

West Marine recommends fenders with 1 inch of diameter per 4 to 5 feet of boat length. So, a 20- to 25-foot boat should use at least 6-inch fenders; a 25- to 35-foot boat should use 8-inch fenders.
