For now, I decided to simply say on my website that there appear to be two main knots which are referred to as the Tugboat Bowline:

Thanks for your continued good efforts at bringing these knots into
awareness. Your statement that "All three of these knots are much
more stable when the end of the rope is wrapped around a second time"
falls beside the truth: in fact, the Perfection/Anglers Loop is no more
stable (it is amply stable as is), and the Knot-B is pretty good as is,
though one needs be mindful to set it well.
Thus, it would be preferable to advise AGAINST the use of Knot-A
on account of its instability, and note that its desireable form is that
called the "Dble.Dragon" by Paul Kruse. A side comment to this can
be that the Knot-B gains some stability from a similar "doubling".
I'm worried that your presentation order imparts a natural bias for
the inferior knot-A. You might then reverse the order (nevermind
what we've discussed among ourselves), giving the well-known
Perfection Loop topmost, then Knot-B, & last AND least, Knot-A.
From this order, advise to "double" things neatly flows to just-viewed
Knot-A, with note about applicability to Knot-B.
While on the page, I notice you echo Ashley's admonition against the
so-called "Left-handed Bowline". Frankly, I think that both the name
and certainly the admonition should be lost: the name unfortunately
leads to some confusion about what "left-handed" means (the nature of
handedness is often not explained nor well understood re knots in laid ropes),
and as his opinion comes w/o any explanation, it's unhelpful
(but as dogma). It has been noted elsewhere that in fact some navy
favors this version; and it can, as noted e.g. by Clyde Soles's book,
be more secure in shock cord (discussed in this forum).
Some will prefer to have the end clear of the eye; some will fear
having a snaggable end outside.
What to call it, then?
Beyond "end on outside version" I don't know.
