How efficient is the Bowling on the bight knot?

The efficiency of a knot refers to how much of the overall strength of the rope is retained when the knot is tied. The Bowline on the bight knot is known for providing a secure loop at the end of a rope or within the rope itself, making it useful in various rigging and climbing applications.

The Bowline on the bight generally retains a significant percentage of a rope's tensile strength due to its structure. The knot facilitates the formation of a fixed loop that does not slip, which is crucial in many situations requiring reliable load-bearing capability. The usual efficiency for this knot has been studied and documented, landing around the 60-70% range in practical application scenarios.

Focusing on the choice indicating 65%, this percentage is often accepted in various rigging texts and resources, making it a strong representative of the Bowline on the bight's efficiency. This indicates that when tying this knot, around 65% of the rope's original strength is preserved. This efficiency makes the Bowline on the bight a favored choice among riggers and climbers when a secure loop is necessary without compromising too much on the rope's integrity.
