What percentage of strength does the Bowline knot typically provide?

The Bowline knot is widely recognized in rope rescue and climbing communities for its reliability and strength. It is known to retain approximately 67% of the rope’s strength when tied, making it an effective choice for applications where it is crucial to maintain a significant portion of the rope’s strength.

This percentage represents the efficiency of the knot relative to the rope's intrinsic strength, which is important in safety-critical situations such as rescue operations. The Bowline is favored because it creates a fixed loop at the end of the rope that does not slip, and unlike many other knots, it is relatively easy to untie after being loaded. Understanding this percentage helps practitioners assess the knot's utility and suitability for various rescue scenarios.
