Lifelines must be size and strength ___.

Lifelines need a size and material that provide dependable strength while staying easy to handle in wet conditions. Not less than 3/8 inch manila line fits this well: manila offers solid tensile strength and grip, plus knots hold reliably when the rope is wet, which is critical for quick, secure lifeline use. A thinner option would risk breaking under load, while a much thicker synthetic rope isn’t necessary and can be harder to manage. Nylon, though strong, tends to stretch under load and is bulkier, which isn’t ideal for frequent, rapid use. Polypropylene floats and can grip less securely and degrade with sun exposure, making it less dependable for lifelines. So the 3/8 inch manila choice provides the right balance of strength, knot-holding ability, and practical handling for lifelines.
