Scott, do you set and dress this knot by tugging on the returning eye-leg until the collar folds the knot in half?
That was an admission some years ago,
but I think he's adjusted since then. IMO, that is
NOT a properly set
bowline (and in any case
is destined upon expected loading to pull out the
collar --can't load the nipping turn w/o getting past
the (too-tightly set) collar otherwise, though it
can be that the SPart yet is overly bent even so.
Also, the one-diameter bend is a hard thing to sell
to firm rope!
And such a binding isn't all so stable : in e.g. the
Perfection/Angler's loop (#1017), that is how the
SPart encompasses the eye legs, and can jam
rather firmly (but maybe its jamming has been
over-rated, for practical uses), but both of the
surrounded parts are under tension along with
the surrounding one; whereas in the BWL of a
tucked-out tail, the tail is NOT loaded,
and the 2dia widening the collar into tightness
can shift into a perpendicular-to-that orientation
(vs. collar-bight apex, one below the other,
so effectively a 1dia turn just backed up by
a 2nd 1dia part) --like having utility poles
in a straight line vs. in a triangular (for 3) group
such as can be found at piers.
I don't think of the collar of a bowline as something required to stay tight.
There is a variation --an extension-- that provides an
opposed-bight collar, which then can oppose the
basic one for a good tight nip on the SPart.
(Follow from the common BWL taking the tail
as the SPart's draw will take it (as done in the
Yosemite BWL and around on the outside
of the near side of the collar, back in on other
side between SPart and that collar side,
and --this is key to being able to loosen it--
then tuck out through nipping turn with
slight twist over/around SPart --which is what
makes this so-tucked tail a tool/lever to use
to prise out some bit of SPart, later, to loosen.
THIS knot can be set tight, as the SPart need
not bend one way or other, the opposed-bights
come together around IT.
AND I think it will defeat the particular loosening
mechanism you discovered fortuitously. (bonus)
