What is a cleat used for on a vessel?

A cleat is an essential fitting on a vessel utilized to secure ropes. It typically consists of a piece of hardware with two projecting arms or horns, which allows sailors to tie knots tightly, ensuring lines are held firmly in place. This is crucial for maintaining control over various lines used aboard a boat, such as mooring lines, fenders, or halyards.

Using a cleat helps create a secure connection to the boat, preventing ropes from slipping. This is particularly important in situations where the vessel may be subject to wind or water currents, as loose lines can cause instability or even pose a safety risk. The design of the cleat enables quick fastening and unfastening, making it practical for tasks like docking or anchoring.

The other options refer to different tools or functions that don’t relate directly to the primary purpose of a cleat. Devices for measuring speed, navigation tools, and safety gear serve fundamentally different roles on a vessel and do not provide the same securing function that cleats do. Understanding this distinction is vital for effective boat handling and operation.
