Skill # 40 Tie a bowline and clove hitch
The bowline is a very secure knot that won't slip, regardless of the load it holds. Tying it is like reciting a nursery rhyme: Pass the free end (the "rabbit") through the loop (the "hole"), behind the standing end (the "tree"), and into the loop. Like this: "The rabbit runs out of the hole, around the tree, and back in the hole." Tighten.
