Yosemite Bowline This strong loop knot is a variation of the bowline that has the free end wrapped around one side of the loop and tucked back into the knot, commonly known as a Yosemite finish. The Bowline knot (and its variants) have two advantages over Figure-of-Eight, that is, it is easier to untie, which is handy after the knot is heavily loaded (by falls), and is marginally quicker to tie. However, I do not use it during multi-pitch climbing or in winter, because I did notice its tendency to come loose over an extensive period of time, probably after the knot has been rubbed by something surrounding without me noticing.
