Re: New Net Knot?

I concur in that emotion, although I too believe I got it
(with about a 50% confidence :o).

Brian asks if it has been seen before:  MAYBE!  ('cause, afterall, I'm
not sure I'm seeing it now).  I found a fine (& clear) monofilament
(nylon?) netting along Cape May Point beach, and noted its unusual
mesh-knot.  Usual if of course the bowlinesque form, with a runner-up
being an unusual "double" of this form.  If you think following the
image on-line is tricky (you're right, there), try analyzing a tiny
translucent tangle of monofilament tightly knotted!  --yes, with a
nice globe (reading papers) manifying lenses & inverted binoculars.
(Hey, I could mail out clips from this--think I've got maybe a dozen
joints (and think more awaits me, on the rocks still--wedged flotsam).)

After about a year & more of occasional futile attempts, I figured
it out (I think).  And what I got is nearly what I got for the "C-knot"
on-line, EXCEPThat I have one part connecting to a different one than
they do (say, e.g., West connects to North instead of to East, if you
assume a normalized 4-points-of-compass mesh form).  And it could be
that indeed these forms are both used (though I've my doubts.  In any
case, the exterior images match up but for this discrepancy (which at
least is conspicuous in their image, as they color-code the two lines).
[In non-"e.g." terms, what I got relative theirs, given that their
WHITE lines are assigned West & North is West connecting to South

But note that they're using HMPE (UHMWPE), DSM's Dyneema (of some
unspecified grade (SK-60, -65, & -75 are the three, I think).  This is
not only super strong (maybe Zylon (PBO) is stronger), but super slick!
So they are right to fear conventional knots.

I have recently read somewhere about a treatment expressly to INCREASE
friction (I think that this was done to try to get more sympathetic
involvement of adjacent fibres under tension--and maybe to HMPE fiber);
but this was aimed at internal friction.

Likely little & lots, resp..  (-;  (But be glad it's not PBO.)

Huh?  I also recall reading in some recent on-line lit (hmmm, under
the Marlow stuff--don't think so, since their best bits were on big
ropes--, or DSM--who might've had some blurbs about advantages & uses
of HPME) extolling advantages of HPME netting, because of 1) lighter
net & 2) smaller line hence less water resistance (which enables using
a larger/more net/ting which would've weighed a lot but not with HMPE
... which means pretty soon you'll have to see your fish in museums.
.:.  Maybe this is not such a good idea!

Thanks for a very interesting knot find--keep it up!
