Knot4U, regarding the improvement I specified above for this latest
slip-free structure, what I'm saying is that at the point where the
toggle /"slip-tuck" is inserted in the above hitch, instead use
that part of material to make a loop around the nip-loop, and use
a piece of the tail/release-line
from the loading side of the objectto form the toggle. Re the "loop around ...", make sure its oriented
such that it's not a somewhat-gripping Bowlinesque/Sheepshank-esque
Half-hitch (i.e., have the crossing reversed), or that could hang up
and frustrate release (just as a Sheepshank holds sans toggle).
The key point is that --as presented above (and at Roo's site)--
the release line takes a hit going around the object before it
delivers force to the slip-tuck/toggle.
I can imagine situations where you just need a quick release, like the example I have above:
You're tugging something non-critical on a boat, and you may want the ability to get the rope
away from your boat instantly if there is some sort of problem that pops up.
And I think those who believe in slip-tucks should go out and actually
try this supposed hauling with quick release with serious loads -- you'll
find things nowhere near so quick (or even releasing)! And esp. to the
point above, with the release line taking friction from the object. It takes
some careful figuring out to build a quick-release that can work for the
situation you hypothesize with a load needing to be freed --one needs
to get much tension taken off of the slip-tuck so that it can be pulled out.
That's not all so easy (or, at least, in looking for such a hitch, I wasn't so
successful in several attempts).
