Here is a further look at commercial-fishing knotting,
manifest in one lobster fishing boat’s gear, as found
11 March 2012.
I’m only just remarking in looking over these photos
–though it seems apparent, also, in those @msg.#28 or 28–
that the “near groundline hitch” (my name) is set
quite loose, to be tightened (such as might happen) only
during usage!? I think that this enables the knot to remain
rather loose, with the initial turn nipping like a bowline’s
central loop, unless loaded from the line being hauled in
the opposite direction, in which case the turn might close
to the rest of the knot better.
The first set of 4 (of two posts of 4@) shows the overall
layout as I found it on the evening of the 10th. There
are heaps of floating (PP or CoEx PP/PE) groundline on
the dock lot --and some new-looking snoods with very
loose hitches tied to them. There is a spool of new,
sinking longline being unspooled with snoods tied on
at the spool, then hauled (by pot hauler, apparently) out
through a re-direction block (which I regret not photographing
and noting its clearance, vis-a-vis a snood hitch passing
through it!), and back aboard boat --at which point, its
having passed the knot tyer, the next snood is then
attached.
In photo #2, the boat is behind the viewer,
and the spool below-left, hauled line returning lower-right
–you can see that the snood is hitched at the spool.
In a later photo, you can see that the knot is still loose
as it is turning over the pot-hauler V-grip wheel; and
later still one can discern the looseness by the pot stacks.
Aboard the boat, where stacks 7 across and 6 high are
in place, tied down (from an elevated metal rail on the
port side to the lowest pot to starboard, w/trucker’s hitch),
and … well, at some later point, the pots need to get bait!
(Maybe it was figured that this was something that could
be done to while away the hours sailing out to sea?!)
The pot bridles are of roughly 1/2" PP laid line, with
an overhand loop as the center knot, each end tied
onto respective pot sides with a clove hitch with its
end tucked back through the bridle’s lay. Snoods are
hitched to the eyes with a double sheet bend with
the tail tucked back through the lay. The spanking new
snoods in that pale blue CoEx PP/PE 3-strand line are
about 9’ long (by crude measure), as cut.
