🔍 Key Concepts

• Synthetic vs natural fiber line characteristics (nylon is synthetic, manila is natural) • Relative breaking strength of different line materials, size-for-size • Resistance to rotting, mildew, and weathering for nylon vs manila

💭 Think About

• Is nylon generally chosen for critical mooring/towing jobs because it is weaker, the same, or stronger than manila of the same size? • Between a natural fiber (manila) and a synthetic (nylon), which one is more likely to rot or deteriorate in wet conditions? • If you wanted a smaller-diameter line that could still safely handle a heavy load, would you be more likely to pick nylon or manila?

✅ Before You Answer

• Compare breaking strength of nylon vs manila of the same diameter (size-for-size) in your study materials or tables • Recall which material is more rot-resistant and commonly used on modern vessels for heavy-duty lines • Eliminate any option that contradicts the known advantages of synthetic (nylon) line over natural fiber line
