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
Bowline all end-to-end joining knots (i.e. bends) have a corresponding eye knot. For example, the corresponding eye knot of the sheet bend is the common (#1010) bowline. Along with the sheet bend and the clove hitch, the bowline is often considered one of the most essential knots. Although the bowline is generally considered a reliable knot, its main deficiencies are a tendency to work loose when not under load, to slip when pulled sideways and the bight portion of the knot to capsize in certain circumstances. To address these shortcomings, a number of more secure variations of the bowline have been
