Sorry to have been unclear. The knot Andreas presents here
and the Octopus hitch are the same knot.
You simply need to move the standing end to the North of the pole in Andreas’ photo. If you test that I think that you will find that the octopus hitch is least likely to come undone of the three. It’s the only one where the final bight can’t get pulled under the spar.
As I said, you need to get used to the knot, and I’ve only done a few tests—those were my initial conclusions. Now I’ll try again, more carefully. I did notice that the knot was very similar, but with the initial bight behind the support. However, it seemed to have different resilience, so I’ll try again.
I recently came across a seemingly pretty good
slip-free hitch, which I see Xarax has in his “136+new hitches”
folder as #12 (and maybe another photo as well : yes, #113).
This knot can be formed by taking the main (S.Part’s)
U-fold up-over-behind the object and out between
its own u-fold legs --which should be kept snug together,
as they are the “frame” against which the slip-tuck toggle
U-fold will be pressed against. (Security against folding this toggle
can be assured by a 2nd slip-tuck through this first one.)
What is nice about this --or especially nice; it’s quick tying
is already a nice point-- is that there is more looseness
around the toggle to enable it to be pulled out --which
action can be hard to do in some of these knots where
parts are pressed close!
#12 is identical with hitches shown in reply nr. 8 and nr. 18
Securing the toggle with a 2nd tuck as Dan suggestst doesn’t do much unless it is passed around the object again first. This ties very well still, but the slipp “freeing” (pulled from top/over) is less direct now, unfortenately..
For reference: #12 left, #113 right. …different ties
Many thanks! for the nice images.
Different versions perhaps, but essentially not
just same neighborhood but same house. (-;
And both of your images are good for showing
structure, but otherwise too “exploded” for use
–too open of the “frame” legs of wrapped U-fold.
And the suggested added slip-tuck sees the initial
release Tail brought back around only the S.Part,
not the object; it locks the slip-tuck toggle; BUT
it makes release come only with considerable force.
Plan-B might be to cast a HH nipping turn w/S.Part
around the Tail’s U-fold.
Plan-C could be making a full/round turn around
S.Part’s U-fold tip, but this will increase needed force
to release.
(Noting that Intended Use --materials, forces, etc.–
is often left out of much of my fiddlings.)
The SE HH around the slip tail could be great, but pulls the hitch open.
The second slip tuck of the tail around the SE seems to not do the job for me and take away from the original release function as you say. Same with the extra wrap around the u fold, destroying the exquisite original tieing of this hitch.
Given the non ideal fixes …#12 should be tested well, “as is” and go from there?!
maybe a variant from the “bight around” collection makes more sense in the end? Nr 12?
