A sailboat cleat is a metal or plastic fitting used to securely fasten ropes (lines) such as halyards or sheets, allowing for quick adjustments. They hold lines under tension, commonly used for docking, anchoring, and sail control, with types including horn, cam, and clam cleats.

Key Types of Sailboat Cleats:
Horn Cleat: Traditional design with two upward-curving arms for securing lines, often used for docking.

Cam Cleat: Features spring-loaded cams that grip the rope when pushed down, allowing fast, one-handed release for racing.

Clam/Jam Cleat: Uses a v-shaped, serrated mechanism to hold ropes tightly, common on smaller boats and control lines.

Deck Cleat: Used on deck for handling mooring lines, anchoring, or securing large ropes.

Key Functions:
Securing Lines: Holds halyards (for raising sails) and sheets (for adjusting sails) in place.

Adjustability: Allows sailors to quickly ease or tighten control lines.

Deck Organization: Helps keep the deck, cockpit, and mast area organized.
