The Mystery of the Forgotten Knot
« on: December 17, 2005, 12:13:59 AM »
Years ago I was taught to tie a very specific and useful knot, while working as a deckhand aboard a shrimp trawler on Austrailia's Northeast coast.

It was used to secure the line that is threaded around the open bottom of the net, thereby cinching it tight and keeping in all the catch.

It was a simple, but repetitive knot, so you built up a kind of braid in the rope as you tied.  To release, we would hoist the nets over the catch basin, with the knots at the bottom.  You grabbed each end, and simply pulled in the release rope.  The released rope alternated with each knot.  So, if you jerked hard on the two ends alternately, the knots of the braid came undone one by one, and the cinch opened, and all the fish fell out the bottom of the net, into the basin.

I loved this knot.  I used to tie my shoes with it, but now I'm beggining to go senile, and I can't recall what the knot was called, or how to reproduce it.

Can anyone help me?

Hi!

In Brittany it is called (technical term  not bad language) " noeud de cul ( de chalut )", fairdikum, " trawler's a-s-s knot (put "- "between "a" and "s" to go under  the language censor's level.

It works as far I could understand on the same principle as  a chain slip knot,  that I  saw in use 40 years ago in military parachuting. It was like ABOK#1827 was to prevent paracord entangling and then become clear with the pulling by the cupola.

Could it be that : http://weblog.greenpeace.org/deepsea/archives/gallery/Tasman2004/slides/CodEnd.jpg  (tasmanian  : Remind me that FCB aka Bowline will surely know it )

Law insist in it being easily and fully releasible, without any mechanical aid. This knotting is done on "le raban de cul" this is a rope  encircling the end opening of the trawling net  ( raban could be  "rope-band" in english ) llok here http://www.ifremer.fr/photos/images/methodes/img0019.jpg  raban is the thick circular rope   Here they are pulling the noeud de cul http://www.ifremer.fr/com/ievolisun/photos/photo1r.jpg
opening the cod end  http://www.nefsc.noaa.gov/read/popdy/monkfish/maryk_3_photos/vass_3_17.jpg but do not see the knotting


Look here  http://www.themodernapprentice.com/knot.htm   it is for falconers but it show clearly the chain slip knot I have in mind.

Hope that will give you the beginning of a trail.
Cheers
