Thanks!
“expelled with a hammer” is an expression to mull over!
This sort of double-speak can be found regarding the
bowline, where in one place it’s defined as a knot
that cannot jam, and then some variation of it (such
as the water bowline) is presented as less likely to jam
(less than 0% chance!). I have seen enough of capsized
bowlines to wonder at the first claim, despite also having
no jamming experience myself, and reading of break tests
where an unbroken bowline (where knots were at both
ends of a test specimen) could be easily untied. “YMMV”
In the case of mooring lines of the fishing trawlers in
Cape May, I think that this OP’s eyeknot would resist
the capsizing --but acknowledge that I don’t understand
how that came to be.
But do note that the version of this knot that I favor is
shown in finished (or nearly so) form by the image in
my post --NOT drawn up (much) further : no, leave it
so that the bowlinesque central nipping loop is just
that, and not drawn into a crossing-knot / Munter=
hitch form. And, as such, it isn’t a great knot for
tying and forgetting, unless perhaps one seizes the
tail somehow; but I take “towing a vehicle” to be
an operation that will see the knot put in at the time,
loaded under observation, and untied afterwards.
The document though still begs the obvious question
as to why this and not some of even its own other
presented knots --the various bowlines, some with
half-hitch workings in a long eye, and multiple turns
around the connected-to object!?
