🔍 Key Concepts

• Synthetic (nylon) vs natural (manila) line properties such as strength, elasticity (stretch), and reaction to shock loads • How chemical resistance differs between nylon and manila fiber • Safety considerations for towing operations: alongside vs astern, including dangers of snapback

💭 Think About

• Which type of line (nylon or manila) stretches more under load, and how does that affect shock loading during towing? • In a towing situation, is it always safer to have a highly elastic line, or can that create additional hazards if the line parts? • Think about which operation most benefits from resistance to rot, mildew, and chemicals rather than from ease of handling and knot‑holding ability.

✅ Before You Answer

• Compare elasticity and shock-absorbing properties of nylon vs manila and decide which towing arrangement would benefit or be more hazardous • Confirm which material has better resistance to chemicals, rot, and mildew • Consider which operation most depends on secure knots and splices that don’t slip rather than ultimate strength or stretch
