What term refers to the metal fitting on which a rope can be fastened?

The term that refers to the metal fitting on which a rope can be fastened is known as a cleat. Cleats are typically found on boats and serve the purpose of securing lines and ropes in place, thereby ensuring stability and safety while the vessel is moored or navigating. They are often installed on docks as well, allowing quick and easy line handling.

In contrast, a beam is a structural component of a boat, often referring to the widest part of the hull. The gunwale refers to the upper edge of the sides of a boat, providing a structural point but not specifically designed for fastening ropes. A propeller is a mechanism used to propel the boat through water, completely unrelated to the securing of ropes. Understanding these distinctions helps emphasize the role of each component in boating terminology and safety.
