Shipping is the most efficient mode of transport for goods on sea. In one year, a single large containership might carry over 200,000 container loads of cargo. While individual ships vary in size and carrying capacity, many container ships can transport as many as 10,000 containers of goods and products on a single voyage. Similarly, on a single voyage, some car carrier ships can handle 7,600 cars on Land. It would require hundreds of freight aircraft, many miles of rail cars, and fleets of trucks to carry the goods that can fit on one large liner ship.
