re the name
Forget worrying about the name : what you did, as you
note, followed a reasonable nomenclature rule
–which is more than one can say for Ashley! (There
are plenty of contradictions in ABOK.)
(“bight” itself is an adventure.)
Btw, I think you’d be a bit better with using the
“water bowline” for a solution --doing the usual
BotB backflip of the twin-eyes bight to finish–
as the 2nd turn I think will give a better lock than
in the dbl.bwl structure. (The water bowline
has a clove hitch base, so to speak, into which
the eyes bight would be reeved.)
