Which knot has an efficiency rating of 60%?

The correct answer highlights the efficiency rating of the clove hitch knot, which is commonly recognized within the context of rigging and knot tying. The efficiency of a knot refers to its ability to hold and maintain tension without slipping, and the clove hitch achieves this with an efficiency rating around 60%.

This knot is particularly useful for securing lines to cylindrical objects, such as poles or trees, making it a practical choice in various rigging applications. It's important to note that while the clove hitch is versatile and easy to tie, its lower efficiency rating compared to other knots like the bowline, which is known for its reliability and strength, can be a consideration when selecting a knot for heavy loads or critical applications.

Understanding the efficiency ratings of different knots allows riggers and those working with ropes to make informed decisions based on the specific demands of their tasks, ensuring safety and effectiveness in their operations.
