This is an interesting interlocking of components,
and in my quick play-test it looks good. But I'm afraid
that the very "interlocking" tying aspect will keep
it from becoming a winner
in the wild.200kg is not a particularly high load. I will go to 500kg next time.
!?
200kg is more than double the weight of most
abseilers,
and hence will be over four times the forces that
an abseil-ropes-joining knot is expected to endure.
4:1 of expected forces is not nothing!
(It might be worth noting that one of the peculiar
results of the
water knot (in tape) slipping under
cyclical loading was evident only in
low loading of
the knot, so that it never took a hard set, and thus
could gradually ratchet out material of the *exterior*
tail. I don't know what sort of similar-loading behavior
might occur only there, for ARJ knots.)
Nice contrasting & bright ropes used for the presentation,
thanks! (Why not also in the loaded sampling?)
Btw, your observation about nearly immediate rolling
of the
offset water knot (EDK) quite surprises me :
I've not seen that (though in some shopping-bag braid
I did just get some movement, though on a firm load),
and the knot does exist broadly
in the wild.And re "footprint", cordage consumption is somewhat
beside the point, in that knot shape will more likely be
any influence. E.g., think of two horseshoes placed one
atop the other vs. facing opposite such that each straddles
one leg of the other --stacked height vs. width. (I've found
an offset knot that resembles that latter case, and the
offset 9-Oh is more like the former.)
My measurement of the
offset 9-Oh is approx. 31dia,
and (by subtraction, basicly) the
OWK 22dia --quite
a bit less than yours, but with slightly greater evident
difference, proportionately --yours a third greater, mine
a half greater (with me measuring a 3/16" dia kernmantle
cord, using tea-bag strings to mark points). !?
