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
International Guild of Knot Tyers expressed a wish to be involved from the outset but due to distance were unable to attend the opening meeting. In 2001, archaeological historian Mike Loades attempted a reconstruction of a British Iron Age chariot. He called upon IGKT member Richard Hopkins for his knowledge and experience of how to use the binding and lashing materials available at that time - rawhide, hemp, and flax - and described his contribution to the project as "invaluable". This involves tying six basic knots - reef knot, sheet bend, sheepshank, clove hitch, round turn and two half-hitches and bowline - against the clock.
