Bowline on a Bight

Bowline on a Bight

Bowline on a bight (referenced in The Ashley Book of Knots) creates a secure loop in the middle of a length of rope. It is a variation of the bowline knot that looks similar but is made with a single strand of rope. If you want to make a dependable loop when neither end of the line is available, this is one knot you can vouch for.

When tied to a climbing harness its ability to easily untie after a severe fall makes it score above the figure eight knot. However, it should be protected further with powerful backup knots with long tail ends when used such.
