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
USS Tom Bowline (1814) — only to be driven off by a gale. "Hornet" arrived five days later, but her landfall coincided with the appearance in the area of British brig-sloop . The two ships closed for action, and "Hornet" damaged "Penguin" seriously enough to warrant destruction of the Briton. The sighting of strange sail on the horizon hastened "Hornet's" burning of the prize, but apprehension turned to relief as the sails proved to be "Peacock" and "Tom Bowline" returning to Tristan da Cunha for the planned rendezvous. "Tom Bowline" embarked the "Penguin's" captive crew and took the prisoners to Rio de Janeiro, Brazil.
