What is the efficiency percentage of the Running Bowline knot?

The efficiency percentage of a knot refers to how much of the rope's original strength is retained when the knot is tied. In the case of the Running Bowline knot, it is commonly recognized for its ability to maintain a relatively high level of strength in the rope while allowing for easy adjustment and untangling.

The Running Bowline generally retains around 60% to 70% efficiency, meaning that it allows a significant portion of the rope’s strength to be utilized even when the knot is tied. This knot is favored in many applications for its reliability and performance in various rigging scenarios.

Given this understanding, the efficiency percentage of the Running Bowline is closer to the higher end of the range, by convention often cited as 60% or more depending on the specific characteristics of the rope being used. Thus, the correct efficiency percentage for the Running Bowline is indeed around 60%, aligning well with the established strength retention values for this knot.
