Someone say it’s bad luck and sailors must avoid it. But hangman’s knot was known on ships not only for the terrible purpose it is named back but also because it is very useful to recover objects fallen in water.
It’s, in fact, a knot which slides on the rope very well, it’s rather heavy and easy to tie. It gives its best on thick ropes but it is always efficient in many other circumstances.
Since it has many coils, it requires a long rope. After a first loop, make another one next to it, by letting the end of the rope pass under it.
Now, it’s time to create a series of coils around the two loops. It’s important to keep coils clamped in order to avoid a long standing line.
Finally, cross the end of the rope inside the final coil.
What’s the right number of coils to do? Tradition says 9 but someone suggest 13. I think 7 coils are perfect and not exaggerate.
