Can anyone ID this knot?
Sorry, I lost the attribution to this
FWIW, bowline failures are quite rare - while its often discussed few people can offer a recent example But I saw a bowline failure last weekend! My knife lanyard is tied with a duobled figure-8 knot to the knife, and the other end is left straight. When rigging down our ship, I tied the other end to a loop in my pocket with a bowline. I kept the knife in my jacket pocket (folded) on my right side, and lanyard was tied to an upper pocket on the left. When ever I needed the knife, I could just grab the lanyard and yank it out of the pocket. This produced a load pattern with the line slack most of the time, with some hard pulls in between. After about two hours I suddenly realised that the bowline had come undone. The line was regular white flag line, double-braided, about 3mm thick. I don't know the name of the improved bowline I used for reattaching the lanyard, but that held for the rest of the day. (googling shows a water bowline that looks quite much like what I did) - Heikki |

After about two hours I suddenly realised that the bowline had come undone. The line was regular white flag line, double-braided, about 3mm thick. I suffered that failure regularly too, and stopped using bowlines in light line for attaching knives/marline spikes etc, switching instead to round turn and (3) half hitches. Critical factors were that the flag line was very smooth - even slippery - and relatively stiff for its diameter, so tended not to jam up. Never had a failure in heavy line though, even when the stress cycle was similar (on a secondary bow line made up to a quay in surging conditions). Which all goes to confirm the importance of a particular type of line and stress cycle when assessing which knot to use. There is no 'universal' knot. -- JimB http://www.jimbaerselman.f2s.com/ Compares the cruise areas of Europe |
