What is the Yosemite Bowline
The Yosemite Bowline is a normal bowline but with an added security tie off. The tail end of the knot is tucked under the loop that forms the bowline knot for added security. The regular bowline knot will become undone easily especially when not under continuous load. Throw in the scraping against the rock in the mix when climbing and it is a matter of time before a normal bowline becomes undone. To prevent this from happening and to make the bowline knot more secure for climbing the Yosemite tie off is added. Yes this does make the bowline suitable for climbing but I still wouldn't recommend it. The Yosemite Bowline is more difficult to tie and to inspect then the widely used and accepted figure eight follow trough. Also when the Yosemite tie is set in the wrong order there is an added risk of it becoming undone. If you tighten the working end first then the knot will capsize and it becomes an accident waiting to happen.
