For a rescue, what kind of stretch do you want in the rope?

• A. Low stretch
• B. High stretch
• C. Moderate stretch
• D. No stretch

Answer: (A)

Rope stretch behavior dictates how predictable and controllable a rescue line will be under load. For a rescue, you want the line to move as little as possible when loaded, so you can lower, haul, or raise a victim with steady, controlled motion. A low-stretch rope provides that predictability because it elongates very little under load, reducing dynamic shocks to the system and keeping the distance between you and the victim stable. This helps prevent sudden jerks, minimizes excess movement, and makes the operation safer and easier to manage. High stretch would introduce noticeable extension as the rope lengthens under load, causing jerky, unpredictable movements and harsher forces on anchors and gear. No stretch isn’t realistic—every rope has some elongation. Moderate stretch still allows some elongation, which can reduce control and precision during a rescue. So the best choice is a low-stretch rope.
