Ferries

A ferry is a merchant vessel used to carry passengers, and sometimes vehicles and cargo as well, across a body of water. Most ferries operate regular return services. A passenger ferry with many stops, such as in Venice, Italy, is sometimes called a water bus or water taxi.

Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels. However, ship connections of much larger distances (such as over long distances in water bodies like the Mediterranean Sea) may also be called ferry services, especially if they carry vehicles.

The profession of the ferryman is embodied in Greek mythology in Charon, the boatman who transported souls across the River Styx to the Underworld.

Speculation that a pair of oxen propelled a ship having a water wheel can be found in 4th century Roman literature "Anonymus De Rebus Bellicis". Though impractical, there is no reason why it could not work and such a ferry, modified by using horses, was used in Lake Champlain in 19th-century America. See "When Horses Walked on Water: Horse-Powered Ferries in Nineteenth-Century America" (Smithsonian Institution Press; Kevin Crisman, co-authored with Arthur Cohn, Executive Director of the Lake Champlain Maritime Museum). See Experiment (horse powered boat).

The Marine Services Company of Tanzania offers passenger and cargo services in three of the African Great Lakes viz. Lake Victoria, Lake Tanganyika and Lake Nyasa. It also operates one of the oldest ferries in the region, the MV Liemba which was built in 1913 during the German colonial rule.
