USCG Exam Practice · Knots, Bends, and Hitches
Which of the following statements correctly describes a characteristic of nylon line as used for dock and anchor lines?
- ANylon floats on the water surface, making it easy to retrieve.
- BNylon loses approximately 10–15% of its strength when wet.✓ correct
- CNylon is resistant to UV exposure but has lower tensile strength than polypropylene.
- DNylon is primarily used for standing rigging due to its low stretch.
Why B is correct
The Boatswain's Manual states that nylon's primary weakness is a loss of strength when wet, approximately 10–15%. Floating is a characteristic of polypropylene, not nylon. Wire rope is used for standing rigging, and nylon stretches under load rather than being low-stretch.
