On a long ocean tow, the bridle should be made up of two equal lengths of __________.

Correct Answer: Option B — chain

Chain is the industry standard for ocean towing bridles because of its superior abrasion resistance and durability. Unlike synthetic lines or wire, chain can withstand the constant friction against the towed vessel's fairleads and the corrosive, high-stress environment of long-distance ocean transits without requiring frequent replacement or complex chafing protection.
