Two half-hitches

Two half-hitches is a knot that is often used to attach rope to poles or other objects.  It is one of many knots that are called hitches.  When a clove hitch is tied around a rope, it forms the two half-hitches. A swift method for securing a knot to a post involves initially creating a loose Granny Knot, while ensuring a long end remains. As the ship sways, it will naturally take up the slack, causing the Granny Knot to transform into Two Half Hitches.
