Cleat

A fitting on a boat or dock used to secure a rope or line.

A cleat is an piece of hardware found on boats, docks, and other marine structures, designed to secure lines or ropes. Typically, a cleat is made of metal, such as stainless steel or aluminium, or durable plastic, and it features two projecting arms or horns around which a line can be wrapped in a figure-eight pattern. This design allows for quick and secure fastening of ropes, which is critical for mooring, anchoring, or securing sails. The cleat’s shape ensures that the line remains firmly in place under tension, while still allowing for easy release when needed.

There are various types of cleats, including the traditional horn cleat, which is the most common, and others like the cam cleat, which uses spring-loaded cams to grip the line, or the jam cleat, which holds the line in place by wedging it into a groove. Cleats are strategically positioned on a vessel, often near the bow, stern, and midship, to facilitate docking and other operations. On docks, cleats are typically mounted along the edge to allow boats to be tied up securely.

Proper use of a cleat is a fundamental skill for any boater, as it ensures the vessel remains safely moored and prevents damage from drifting or uncontrolled movement. Misuse, such as improper knotting or overloading, can lead to accidents or damage to both the cleat and the boat.
