Slipped bowline
The common bowline is a tried-and-trusted knot, much used by all who have to make rope work
for them; although it is not especially strong or secure, it can sometimes jam and be hard to
undo. So if it is to be tied in coarse cordage and then heavily loaded, consider using this slipped
version.
Pass the working end up through the loop (1), and around behind the standing part of the line (2),
as if tying a basic bowline (see page 63), but then tuck a bight (not the end) down through beside
the adjacent loop leg (3). Tighten the knot around this bight (4). To release the knot, simply tug
the end to remove the drawloop.
