Cam Cleat

A mechanical device with spring-loaded, opposing cams that grip a rope or line to hold it securely while allowing for quick adjustments. 

A cam cleat consists of two spring-loaded, serrated cams that rotate inward to grip a line when it is pulled taut. The design allows for easy engagement and release by simply pulling or lifting the line. Cam cleats are commonly used on sailing vessels to secure control lines such as jib sheets, mainsheets, or halyards, enabling quick adjustments without the need for tying knots or manually securing the line to a traditional cleat. They are particularly useful in situations where frequent trimming or rapid release is necessary, such as in dinghy sailing or racing yachts. Cam cleats come in various sizes and materials, including plastic, aluminium, and stainless steel, to accommodate different loads and environmental conditions. Some models include fairleads to guide the line into the cleat, improving efficiency and reducing wear. Proper maintenance, such as rinsing with fresh water to remove salt and debris, helps ensure smooth operation and longevity.
