🔍 Key Concepts

• Elongation characteristics of nylon line under load • Difference between working elongation and danger/critical elongation • Behavior of nylon line just before it parts (snap-back and internal damage)**

💭 Think About

• Think about at what approximate percentage of stretch nylon line changes from safely elastic to dangerously overstressed. • Consider what training materials say about when nylon line’s internal fibers begin to suffer permanent damage rather than just elastic stretch. • Compare the typical safe working elongation range with the point where crews are warned to stay clear due to possible parting.

✅ Before You Answer

• Recall the typical safe working elongation range for nylon mooring/towing lines. • Recall the approximate elongation at which internal damage and risk of parting becomes a serious concern. • Make sure you distinguish between normal working stretch and the point where the line is close to failure.
