The Cleat Hitch is often used when mooring a boat temporarily to a dock. It’s also what you should use to secure the line after raising or lowering a flag.
To tie the Cleat Hitch, follow the steps in the diagram. The “far horn” is the bottom of the cleat on a flagpole, or the one further away from a boat being moored. The “near horn” is the top of the cleat on a flagpole, or the one closer to a boat being moored.
Once tied, the tension on the line holds the hitch secure.
