Roving Fender

A spare fender, held ready by a crew member in case of emergencies.

A roving fender is a type of fender used on boats and ships to protect the hull from damage caused by contact with other vessels, docks, or structures. Roving fenders are typically cylindrical in shape and can be easily moved or adjusted to provide protection at different points along the hull. They are often made of durable materials such as rubber or foam and are designed to absorb impact and distribute pressure to prevent damage to the vessel.
