fishermans v splice

[DrewB]

id always been told that a fishermans will reduce rope strength by up to 50% but i never really believed it actually did.So i spliced up an eye and tied a fishermans on the other end and got it tested. the splices hold out to just over 3tonnes. the fishermans snapped at 1.36 tonnes. we had to cut the rope off the shackle as it melted itself together, and the splice was still fine.the bang it makes when it snaps is scary.

That is interesting, where did you do the testing?

its a big rope centre near me-they can destroy with 100s of tonnes of power! its a straight pull though-we are going to try and set up shock loads next.

The break strength of knots?

So, do the knots fail in the same places and if so why?

the fishermans choked the rope and thats were it snapped it. snapped twice in the same place. also done some splices with eyes just big enough for the carabiner-the small eyes snapped open at approx

6ookgs lower than big eyes, if you get what i mean.
