Put me right off the rolling hitch idea. |
Probably tied wrong. One of the great virtues of the rolling hitch is that it is practically jam-proof since the end of the
rope is tied on the opposite side of the chain from where the force is exerted. So no matter how hard the snubber got loaded up, the end of the
rope and that last turn you have to get undone is never stressed so can't jam. Once you get that unstressed turn undone, you just unwrap the rest of the
knot -- simples.
There are two different ways to tie a rolling hitch -- the "real way" and the lubberly way. Some purists sneer at me, but I tie it the simple way -- just like a clove hitch with an extra turn or two in the direction of stress. The "real way" requires a tuck, which I've never done since I learned the knot from my father decades ago the "simple way" and it has always worked flawlessly for me (and for him).
Maybe the "real way" is more prone to jamming; I don't know since I never tie it that way. I wouldn't think so, but I can't prove it.
Even if you don't use it for your snubber, you need to know the rolling hitch, which is one of the fundamental knots on board with dozens of uses. One of its other critically important uses, for which I don't think any other knot would quite
work, maybe a Kleimheist, is unloading and clearing a
winch with a riding turn on it. If you've never had a riding turn on a
winch, you don't know how scary and dangerous it can be. With another line tied on with a rolling hitch, it's pretty simple to clear. Otherwise -- not, and you can end up with a solidly jammed sheet and possibly a knockdown or broach. The rolling hitch is needed for that because you need to be able to slide the knot up the loaded line in order to walk the loaded line in -- the rolling hitch holds in one direction but slides in the other -- it's a totally cool knot.
The "textbook" rolling hitch has two turns in the direction of stress, and one in the other direction. But it works just as well with three or even four turns in the direction of stress, and I sometimes do this if I feel that extra
security or extra friction is needed.
