Pictures of Bowline Lock WE RT 1 are shown below.
FIRSTLY, I strongly urge knotters to treat the orientation
that here is labeled "back" as the PRIMARY one in which
to view a
bowline --as it better presents the knot, better
showing the more interesting crossings (whereas the path
of the bight legs is pretty easy to comprehend, simple,
and they are behindmost in this view).
I really think that so much of the confusion about a
bowlinecomes from the bassackwards ubiquitous illustration of
the knot, typically --reversed, e.g., from how the
sheet bendis commonly shown.
Now, let me point out that what I've called "end-bound..."
is just this knot but with the extension wrap of the tail
doing something more useful : nipping and locking (as best
it is able, which isn't always so great/enough) the main
nipping loop (which is reciprocating). Turn that tail over
the crossing point of the main
turNip !
I prefer this in the
double bowline body, where this extra
wrap will have 3 diameters within it (best approximating a circle).
But I have seen even that knot, tied in some recalcitrant,
firm, soft-laid, slick, thin (4mm?) polypropylene hold only
briefly, than all the round turns just simultaneously
loosened/expanded !!

In this cord, the simpler knot
presented by Prohaska seemed to be a better solution
--it wasn't so snugly tight on setting, but the material
tried to spring open and was easily limited, as the sharper
turns made it want to open like scissor legs, easily resisted,
not expanding like a big eater's waist line.
