Don’t just assume a visitor on your boat knows how to cleat a mooring line, as you may be astonished and dismayed by the unsatisfactory results. The Cleat Knot, or Cleat Hitch is used to attach a rope to a cleat. A Cleat Knot is unlikely to loosen up but can be undone quickly if you need them to. This knot is most frequently used to secure a boat to a dock. It is also used for fastening halyards, dinghy bow lines, out hauls and down hauls.
