🔍 Key Concepts

• Towing gear materials – how chain behaves compared to wire rope in real sea conditions • Abrasion and chafing when gear passes over bits, chocks, and fairleads • Shock loading on a long ocean tow and how weight and flexibility help or hurt

💭 Think About

• For each statement in the options, ask yourself: Is this really a unique advantage of chain over wire rope during a long ocean tow? • Think about where and how the bridle runs on the tug and on the tow – what parts are most exposed to rubbing, shock, and sudden strain? • Consider whether any of the options describe something that might be true in theory, but not actually the main practical reason mariners prefer chain bridles on ocean tows.

✅ Before You Answer

• Compare abrasion resistance of chain vs wire when passing over metal surfaces under heavy load. • Consider which material better absorbs shock loads from seas and towline surging on a long ocean tow. • Ask: Does chain really require less maintenance overall than wire rope, or does it just handle certain types of damage better?
