The Somerville Bowline was devised by Topologist. There have been a lot of methods posted on how to tie this knot due to its instant popularity in the rope scene. There are a lot of similarities between this and the French/Portugese bowline that was my primary cuff for some years. This new cuff is just as easy to tie and has some benefits which have caused it to become my primary single column cuff. Take the time to practice this knot over and over again until you can do it with muscle memory alone.
