Reroute Eskimo bowline
« on: April 21, 2018, 10:48:19 PM »
Hi All,
        Many years ago I had Lee's Eskimo 8 bowline (A) and Lee's Eskimo 8 bowline (B),they both are have
figure 8 knot tie to Eskimo nipping loop, I found  version (A) would jam bad and version (B) can handle heavy load.
(see link 1  Xarax The Knots Master have spent a lots of hours analyse my knots).

After many tests and study, I think I have some answer, version (B) has 3 rope diameter in the nipping loop,
that mean it can help to lengthen the collar near the standing part, and this loop is quite well balance,
the standing was sitting on the same side of the outgoing leg. the figure 8 knot has a lots of rope length tie to a nub,
waiting for the incoming leg to tighten the figure 8 knot, but the Eskimo nipping loop is so powerful,
it don't give much chance for an incoming leg to tighten the figure 8 knot, if nothing helping here to tighten the figure 8 knot,
the final loaded loop will look very ugly, the nipping will be very tied and the two loops of the figure 8 knot will be very loose.

The good thing this version (B), the tail was sitting in the right place, when you load the loop, the standing will pull and rotate the tail, try to tighten the figure 8 knot, make it more solid nub, yet it is not too tie, after heavy loading you can even untie the knot from the top collar. and also while tail rotate toward the collar that near the standing part, it help to lengthen the collar a little more, make it easier to untie this knot.

So far I know all four versions of Eskimo bowline will jam, only the Eskimo bowline with the tail cross (see picture 4)
can handle little more weight then the other three versions.
 
Base on my sturdy above, I come up this "Reroute Eskimo bowline", it turns very nice, well secure, solid knot, yet it is so simple, so easy to untie after heavy loading, probably many people tie it before. In this forum kd8eeh have tie the similar knot, but dress little difference before see link 2,  when you loading this knot, it don't have the tail rotating effect to tightening the top collar,
it will be very loose at the top collar. but still is a fine knot and will not capsize and is a stable knot.

I have abundant Lee's Eskimo 8 bowline (A) for long time ago, for (B) version, from now on, I call it "Lee's Eskimo 8 bowline "
I have 8 videos testing these knots, I only post a few of them here, you want to know more have to see it
from my channel "alanleeknots' at YouTube.

Hi All,
         I post few more videos here, now we get to know more about the famous " Eskimo bowline ".
         And this time I draw some line on the tail of Reroute Eskimo bowline, to show the " Tail rotating effect " (self tightening).
         Ever the Unknown Eskimo bowline is way better than the" Eskimo bowline ".

Hi All,
        Can the Kalmyk loop Unseat the Bowline as King of Knots? absolutely not. I have two videos to share with.
        king of the knots is untouchable, Kalmyk loop is many blocks behind.
        Also see these two links;   http://igkt.net/sm/index.php?topic=5324.0

Thanks for sharing the videos.

I prefer to think of these knots as 'anti-Bowlines'.

And you can therefore have a slipped anti-Bowline (aka 'Kalmyk' eye knot).

In the same way, you can also have a slipped common (#1010) Bowline.

As Xarax pointed out long ago - there are in fact 4 variations of the common (#1010) Bowline and 4 variations of the anti-Bowline.
(due to nipping loop chirality..ie Z versus S twist and tail inside or outside of the eye).

Probably would be instructive to test a slipped common (#1010) Bowline as an experimental 'control' in comparison to the slipped anti-Bowline. I am not convinced that it is valid to test different knots within the same length of specimen cord. It should be slipped (#1010) Bowline v slipped (#1010) Bowline at either end. And then the same for the slipped anti-Bowline (same knot at each end).

The tests to MBS yield point should keep increasing load till failure is reached (no stopping part way through).

Tests that are intended to probe jam resistance could be stopped at various load milestones to check if jamming has occurred (or not).
