Which line material is best suited for a mooring or towing application where shock-load absorption is the primary concern?
- ✓ Nylon, because its elasticity absorbs shock loadsCorrect
- B. Polypropylene, because it floats and is lightweight
- C. Polyester/Dacron, because it has very low stretch
- D. Manila, because it gives clear warning before failure
Why A is correct
NAVEDTRA 14067 §3-1 states that nylon is very strong and elastic and is excellent for mooring and towing because its stretch absorbs shock. Polyester has much less stretch, polypropylene is weaker, and manila is weaker than synthetics.
