Lore & Background
Merchant ships operate under various flags, with many using a 'flag of convenience' from countries like Liberia and Panama that have more favorable maritime laws. The Greek merchant marine is currently the largest in the world, accounting for some 16 per cent of global tonnage. During wars, merchant ships may serve as auxiliaries to navies, delivering military personnel and materiel.
Reader's Guide
Merchant ships are fundamental to global trade, handling the bulk of international commerce. They range from small coastal vessels to massive supertankers like the FSO Knock Nevis, the largest vessel ever built. The UNCTAD review categorizes them into oil tankers, bulk carriers, general cargo ships, container ships, and other types including gas carriers and ferries. Despite their size, supertankers are often unprofitable at full capacity; modern TI-class tankers typically use no more than 70% of their capacity. Tankers have also been involved in major environmental disasters when sinking near coasts, causing oil spills. The United States Coast Guard defines a commercial vessel as any vessel engaged in commercial trade or carrying passengers for hire.
