This knot looks like a slippery half hitch, but it’s not. The mooring hitch holds

fast under load yet comes apart instantly with a pull of the working end. You can
tie it loosely and allow it to slide up to the rail like a slip knot, or jam the knot
anywhere along its length so you can reach and release it without getting off
your horse or out of your boat. This slick little hitch is well worth learning!
