The prefix "Double" is generally used for knots which have two loops
Hmm, like "Dbl.Fishermans Knot", "Dbl. Scaffold knot" (Budworth!), "Dbl.Overhand",
& "Dbl.Constrictr"?
No, "double" seems to have use in denoting a repeated central part of some knot,
typically to increase security.
The first picture is a Double Bowline. The second picture is a Triple Bowline
Exactly the sort of confused nomenclature we want to
avoid !
"Twin-/Dual-Eye" (& appropriate variant for other numbers) is perhaps the best
qualifier one can use for loopknots. ("loop" is used, but is such an overloaded term,
it's best to avoid it here; "eye" is pretty precise).
Derek's knot is a bowline with a bight (and then some special positioning ...),
which can be used to yeild three eyes. There are many bowlinesque ways to make
multiple eyes (e.g., the Bwl on a Bight can do multiples of 2; Derek's, 3 by 2
--i.e., odd numbers); Derek's & Bwl on Bight tying can be combined (which finish
would give Derek's in this case 4 eyes & a triple
collar).
NAMES are going to be problematic, and beyond control, to much degree,
but one can try to fight The Good Fight, sometimes. Some kind of more *scientific*
nomenclature--tedious to the ear, eye, & fingers (!)--will be needed for exact
references, helpful for classification.
