Yosemite bowline form a highly dangerous slip knot. Additional safety is achieved by tying with a tail (see below). When finished, the working end forms a figure eight. Because of the danger of incorrectly tying the Yosemite bowline, it may be safer and less error-prone to use a standard or double bowline with a backup stopper knot added to the tail, such as a double overhand knot tied around the loop. The Yosemite finish can be applied to other bowline variants, such as the double bowline. While the knot's versatility suggests it as a convenient tie-in for attaching a climbing rope to
The 85 Ways to Tie a Tie described in the book, in order of size, are as follows. Terminal sequences (the final three moves that end in the tying of the knot) are in bold. The knots are sometimes designated by their number alone (e.g., FM2 for the four-in-hand, with "FM" standing for Fink-Mao). A knot is self-releasing if, when the thin end is pulled out through the knot, no knot is left; as all knots start on the left, a knot is self-releasing if the terminal sequence is Ro Li Co; it is "not" self-releasing if the terminal sequence is Lo Ri Co. Symmetry and self-releasing
