What line or rope is the best choice when high storm surge is expected?

• A. Nylon
• B. Polyester
• C. Aramid
• D. Polypropylene

Answer: (A)

When a line must endure high storm surge, the ability to absorb dynamic shock and protect the rigging is the key. Nylon stands out because it stretches under load, dissipating surge energy and reducing the peak forces on cleats, winches, and anchors. That elasticity provides a forgiving line that can endure repeated gusts and waves without snapping, even in wet, salty conditions. It also combines good tensile strength with solid abrasion resistance, which helps when a line rubs on fittings or deck gear during a storm.

The other materials don’t offer the same balance. Polyester is strong and UV-resistant but stretches less, so it doesn’t absorb shock as well. Aramid has very low stretch and high strength, which can transfer loads with less give and may lead to higher peak stresses and more wear under rough handling. Polypropylene floats and is lightweight but has lower strength, poorer abrasion resistance, and degrades under UV and salt exposure. Nylon’s combination of elasticity, strength, and practical durability makes it the best choice for high storm surge conditions.
