A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines [1] that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 19th century; however, there were exceptions that came before.
Screw-driven steamships generally carry the ship prefix "SS" before their names, meaning 'Steam Ship' (or 'Screw Steamer' i.e. 'screw-driven steamship', or 'Screw Schooner' during the 1870s and 1880s, when sail was also carried), paddle steamers usually carry the prefix "PS" and steamships powered by steam turbine may be prefixed "TS" (turbine ship).

Fitch was granted a U.S. patent on August 26, 1791, after a battle with James Rumsey, who had also invented a steam-powered boat. The newly created federal Patent ...
The shipping company is an outcome of the development of the steamship. In former days, when the packet ship was the mode of conveyance, combinations, such as the well-known Dramatic and Black Ball lines, existed but the ships which they ran were not necessarily owned by the organizers of the services. The advent of the steamship changed all ...
The trips by paddle wheel steamship to Panama and Nicaragua from New York, Philadelphia, Boston, via New Orleans and Havana were about 2,600 miles (4,200 km) long and took about two weeks. Trips across the Isthmus of Panama or Nicaragua typically took about one week by native canoe and mule back.
The first small vessel that can be considered a steam warship was the Demologos, which was launched in 1815 for the United States Navy. [1] From the early 1820s, the British Navy began building a number of small steam warships including the armed tugs HMS Comet and HMS Monkey, and by the 1830s the navies of America, Russia and France were experimenting with steam-powered warships.

The engines were installed in early 1839, following the ship's launch in October 1838. The gearing provided some additional technical problems. Smith geared the engines to the propeller via spur-wheels and pinions, the largest of which was toothed with hornbeam (a white timber traditionally used for gearing in windmills ). [ 18 ]
The first successful transatlantic crossing by a steamship occurred in 1819 when Savannah sailed from Savannah, Georgia to Liverpool, England. The first steamship to make regular transatlantic crossings was the sidewheel steamer Great Western in 1838. [3]
