A double bowline (or round turn bowline) is a type of loop knot. As with a standard bowline, the knot cannot tighten. The Federal Aviation Administration recommends the bowline knot for tying down light aircraft. There is a potential with beginners to tie what is known as an Eskimo bowline. The bowline is sometimes referred to as "King of the knots" because of its importance. Later, tailless kites incorporated a stabilizing bowline. The final loop of a sideways bowline will slip. This forms a more secure loop than a standard bowline. A triple bowline is used to make three loops. The Yosemite bowline is often used in climbing. The bowline is used to make a loop at one end of a line. The common bowline shares some structural similarity with the sheet bend. The Yosemite finish can be applied to other bowline variants, such as the double bowline. One person ties into one side of the line using a French bowline. Pressure is distributed over a wider area than in the case of a standard bowline.
