Written Instructions — Bowline on a Bight

Start mid-rope — no free ends Double the rope to create a bight. Fold bight back on itself.
Form loop in doubled rope Cross the doubled bight over the standing strands to form a loop — like starting a bowline.
Pass bight up through loop Push doubled bight end up through the loop from underneath.
Spread bight over standing knot Open the bight loop wide and fold it down around both standing strands of the knot.
Pull all four strands Tighten by pulling all strands. Two parallel fixed loops result.

As a rescue seat: one loop behind each knee, person sits in both loops — supports body weight without a harness.
The two loops must be equal size — adjust before final tightening.
This knot cannot be tied with free ends — it specifically requires working from a bight.
Inspect carefully: the bight must be completely around both standing strands, not just one.
