A "Double Zeppelin bend" is the name of a bend were either the collars or the nipping loops are doubled.
Says who?
"double tucked Zeppelin bend" <<< gets my vote. Makes sense to my poor mind.

The ambiguous denotation highlighted by XaraX suggests that SScott's conclusion
might be the better course. I look to the Bowline & Sheet Bend (complementary
knots) and the use of "double" with them : I guess that the Sheet Bend is in the
same situation (w/less structure, slightly) as the R.Z. bend --i.e., "doubly tucked"
certainly is an apt (if unnecessary?) description for it, too.
Recall that for the R.Z. bend there is the variation where the continuation
from the SPart's turn around the ends is a
full turn, i.e., continuing
to then collar the
opposite SPart (not sure of benefits, but it's not
a big expansion from the R.Z.). And it's unlikely to go a half-turn further
and get the sort of
doubling that one might posit exists for the
Dbl.Bowline--the 540degree turn is just bulky w/o benefit, to my mind.
.:. Use of "double" in knotting is currently problematic (used e.g. also for
eye knots w/2 eyes --a use I think should be out of bounds) ; can we see
a rationale to guide us in this?
