What is a Z-drag system and when is it used?

• A. A simple direct pull with a single anchor.
• B. A Z-drag is a high-advantage rope hauling system using two anchors and pulleys to maximize force for lifting or dragging a person or heavy load from the water.
• C. A Z-drag is a type of life jacket.
• D. A Z-drag is a rescue boat.

Answer: (B)

A Z-drag is a high-advantage rope hauling setup that uses two anchor points and redirect points (pulleys) to multiply the pulling force on a victim or heavy load in the water. By routing the rope in a zigzag between the two anchors and the load, several segments share the load, so a rescuer can move a heavy person or object with far less effort than a simple direct pull.

Use this when the load is heavy, when distance or current makes a direct pull impractical, or when you need to bring the victim or load toward shore or a safer position while maintaining good control. The two anchors provide the necessary redirection and stability for the mechanical advantage, making it possible to generate enough force to move the load safely. Always ensure anchors are solid, protect the rope from sharp edges, and maintain clear communication with the team during the haul.
