Nylon is the strongest synthetic material for commonly used DIY ropes. Nylon is best used for absorbing shock loads, such as towing, because it has an elasticity characteristic that will absorb the shock and return the rope very close to its original length after being stretched. Nylon can last several times longer than natural fiber ropes because it is resistant to rotting, oil, and most common chemicals. Nylon does not float and it will absorb water, which causes it to shrink slightly and to lose some of its strength (10-15%). Nylon is ideal for use as bow-to-stern towing, safety lines, tow ropes, tie-downs and anchor lines.
Warning: Do not use for overhead lifting, support of human weight or athletic equipment, Do not exceed safe working load detailed on the package. Shock loads (stress, jerk) can reduce working loads by as much as 33%. Never stand in line with ropes under tension; rope (especially nylon) may recoil or snap back. Knots reduce rope strength by 40%. Replace the rope if there are signs of wear, such as broken fibers.
