Hark! It is I...."that guy with the face!" I come bearing a couple of interesting, noteworthy, thus far unaddressed and wholly fantabulous pieces of knot knowledge with which I shall add to the present and ongoing deliberation! I shan't be persuaded otherwise!
Huzzah!
For my first exhibit, I intend to make everyone familiar with some lesser known, inherently secure (aka "locked), variants of the bowline. Take a gander, if you will, at the diagram below. It contains a trio of locked bowline variants which have yet to be brought up in this thread.
Just to establish some facts before I get to my introductions, it should be understood that every locked variant that I am about to discuss all possess the highly desirable characteristic of having three rope diameters contained inside of the nipping loop. The first is known as the "EBSB" bowline, which is an acronym for End Bound Single Bowline, and it is comparable to (or, in some cases, superior to) most any other inherently secure bowline variant, including but not limited to the original Yosemite Bowline.
The second bowline variant on the menu is known as the "Lee's Link Bowline," which is easily one of the coolest variants, both conceptually/structurally and visually. This knot's structure makes it especially resistant to breaking and, once again, it is considered to be equal to or (sometimes) better than other locked bowline variants. If you enjoy learning how to tie new knots (lord knows that I do!), then I strongly suggest that you put learning this one on your list!
Tertiarily, we have "Alan Lee's Yosemite Bowline," which was inspired by the original version of the knot. This cleverly designed variant is considered to be notably superior to the original Yosemite Bowline because of how the tail ends up getting secured within the nipping loops instead of simply pulled through the collar. For those of you who use the original Yosemite Bowline, I'd strongly encourage you to switch to this variant instead. If you can tie the first, then tying the second will be mindless and you'll be safer as a result.
Next, this second diagram contains at least four bowline variants which also have yet to be introduced to this delightful thread. I'll make this one simple: all three in the first row and the one in the middle in the second row are the variants to which I am referring. They are all, in some form or another, inspired by and/or related to the "Triple Bowline." For anyone seeking a truly bomber double loop knot, I would like to direct your attention to the second and third knots within the first row.
The "Triple Bowline (simple lock)" is one of my all time favorites. It starts similar to a standard "Triple Bowline," but instead of utilizing the working bight to form a third loop, this knot finishes with the bight secured inside of the collar, pretty much exactly how the tail is secured for the original Yosemite Bowline. As a result, this knot can be considered to be inherently secure ("locked"), meaning it can be used for life support applications.
The second one I just mentioned, first row, far right, is basically the same as a regular "Scott's Locked Bowline," except this is a midline knot (the previous knot is also tied midline) and it is instead formed using a bight, creating a variant which has doubled strands throughout.
Thanks for reading this! I hope you learned something and/or discovered some exciting new knots to learn and analyze!
