Marine transportation refers to the movement of goods and people over water using various types of vessels. This includes large cargo ships, ferries, and cruise liners that travel across oceans, rivers, and lakes. It plays a crucial role in global trade, as many products are transported by sea due to its efficiency and cost-effectiveness. In addition to commercial shipping, marine transportation also encompasses recreational activities like sailing and fishing. Ports, such as the Port of Los Angeles or Port of Rotterdam, serve as key hubs where vessels load and unload cargo. Overall, marine transportation is vital for connecting different regions and supporting economies worldwide.
