Double bowline Double bowline A double bowline (or round turn bowline) is a type of loop knot. Instead of the single turn of the regular bowline, the double bowline uses a round turn. This forms a more secure loop than a standard bowline. Though called "double bowline" by Clifford Ashley, this name is also reasonably descriptive of a different knot: the bowline on a bight. Because of this ambiguity some sources differentiate by using one of the alternate names above. And at least one other source uses the name "double bowline" for a mid-line loop knot made by tying a basic bowline
Marlinespike hitch this hitch is not allowed to collapse into that shape. When it does capsize into a traditional noose, it can jam against the rod, making it much more difficult to release. The hitch is frequently used by hammock campers to attach whoopie slings to tree huggers. By passing the working end through the marlinespike hitch, this knot can be used as an alternative method of tying the Bowline knot. Passing through in the opposite direction will give you the Cowboy bowline (also known as the left-hand bowline, Dutch marine bowline or winter bowline). Below is a basic method of tying.
