Waterborne transport is the movement through water of a vessel such as a barge, boat, ship or sailboat water body (sea, ocean, lake, canal or river). Buoyancy is common to shipbuilding, which makes the hull a dominant aspect of its construction, maintenance and appearance.
Although it is the slowest compared to other types of transport, modern sea transport is a highly effective method of transporting large quantities of goods. So, in the last decade on commercial vessels, there were almost 35 000 people and transported more than 7.4 billion tons of cargo.
Transportation by water is much cheaper than air transport for transcontinental shipping. Not long sea shipping and ferries remain competitive in coastal areas.
