If you were to pass a stopper on a wire rope, what should the stopper be made of?
Official USCG Answer & Rule Citation
Correct Answer: Option A — Chain
Chain is the only appropriate material for a stopper on wire rope because it can bite into the wire without slipping. Fiber ropes like manila or nylon lack the necessary friction and structural rigidity to hold a tensioned wire rope securely, posing a significant risk of the stopper failing.
