The Cleat Hitch
In nautical contexts, a cleat is a device attaching a rope. The traditional design is attached to a flat surface and features two “horns” extending parallel to the deck.
Uses: The Cleat Hitch, or Cleat Knot, secures a rope to a cleat. It is deceptively simple and an unwary skipper who invites visitors to tie the dock line to a cleat may be dismayed by the unsatisfactory results.
