What is the purpose of a progress capture knot in a hauling system?

• A. It allows air flow
• B. It speeds up the system
• C. It allows control of the rope while moving the load and prevents backsliding when not loaded
• D. It replaces the main rope

Answer: (C)

In a hauling system, the progress capture knot is used to control the rope as you move the load and to prevent backsliding when the system isn’t actively loaded. It grips the rope so you can hold or “capture” the progress of the haul, keeping the load from slipping backward when you pause or adjust. When you need to take in more rope or start moving again, you can release or reposition the knot to allow further rope movement, while still resisting unintended movement when there’s no active pull. This function is about secure, controlled feedback and stability in the haul, not about creating airflow or speeding up the system, and it does not replace the main rope.
