Soft Halyard or Line Shackle

[Brion Toss]

Hi there,
I like this variation on the theme, and would suggest that the way is open, with this and with normal soft shackles, for an even stronger attachment, through the use of four-strand buttons or lanyard knots. That way the shackle would not be the limiting factor, and in your case you'd have deeper redundancy for the permanently-affixed piece.
My favorite sheet configuration remains a 1-piece pair, secured to the clew with a soft shackle, with the whole works coming off for sail or rope maintenance or stowage. With this, one is not limited to HM sheets.
Fair leads,
Brion Toss

You can also make the button loop out of one size larger line and get the strength back and the four-strand button is an interesting idea. I would not use this soft line shackle for sheets as the knot sticks out where it would hang on the rigging. I am using eye splices in XLS and a soft shackle to the clew ring with the knot held in the clew ring as shown below:

I have an extensive writeup on soft shackles here (first of 7 pages)

But what do you think about a name? Soft line shackle, or soft halyard shackle, or some combination?

Finally, what is a 1-piece pair?

Has anyone here done any testing on the luggage tag loop with several diamond knots in a row so as to be able to attach the loop at various points to make it adjustable?

In other wards, if you make the loop with many diamond knots, do all the diamond knots have the same strength?

I suppose I should just do some testing and write it up, but I want to rig my boat and go sailing!

Thanks,

Anton

Hi,
I haven't done tests with that configuration, nor on Mr. Otto's sling with a series of Brummels, but those both sound like things worth doing. Meanwhile, I finally sent off some more "Improved" shackle samples for destruction-testing, and we might have results as early as today. Stand by.

Oh, very cool! I guess I can find the time to do some pull tests, problem is how to rig up a scale.

Maybe a bathroom scale with a lever or something.

I think if I do a loop with multiple knots, and start at the farthest one, it would tell me if the first one is the most likely to break.

If they break sequentially, the only question is at what tension they break.

Hm.

I eagerly await new pull tests!
