Ferry, service providing conveyance for passengers and
goods across a river or other body of water in a boat and, more recently, in a
hydrofoil, air-cushioned vehicle, or an airplane. The transport vehicle is also
called a ferryboat or a ferry plane. Specially built ferryboats carry railroad
trains between points where railroad bridges are impractical.
The ferryboat usually operates over short distances,
as across a river, bay, or from point to point in a harbor, such as the Staten
Island ferry in the harbor of New York City, which carries both passengers and
vehicles. If a ferry's route requires it to make frequent passages over short
distances, it is built as a double-ended vessel that can be loaded and unloaded
at either end and that operates without turning around at terminal points. For
longer or rough passages, such as the services across the English Channel and
the North Sea, the ferryboat has a conventional ship shape, and in its
structure is better protected from the seas during transit.
Ferryboats usually have only one vehicle deck and
carry passengers in the superstructure. Modern ferryboats are usually powered
by diesel engines. Hydrofoil and air-cushioned vehicle ferries, carrying
passengers only, are in extensive use in some parts of Europe, and recently
plane ferries have become increasingly important for rapid transit.
Other major ferryboat services operate in the Baltic
Sea between Copenhagen and Malmö, Sweden; across the strait of Bosporus in
Turkey; between the several Japanese islands; and in the United States, across
Lake Michigan and across Puget Sound in Washington state.
