💭 Think About

• Which type of line can suddenly part and recoil with the most dangerous force? • Is a line more dangerous when slack and coiled, when moving but slack, or when tight under heavy load? • Think about where serious injuries and fatalities most often occur when working around mooring or towing lines.

✅ Before You Answer

• Identify which situation creates the highest stored energy in the line • Recall standard safety advice: crew should avoid standing in the bight or snap-back area of which lines? • Verify which option describes a condition, not just a physical arrangement, that makes a line hazardous.
