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 that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for paddle steamer or "SS" for screw steamer. As paddle steamers became less common, "SS" is assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for motor vessel, so it is not correct to use "SS" for most modern vessels.
SS Savannah was an American hybrid sailing ship/sidewheel steamer built in 1818. She was the first steamship to cross the Atlantic Ocean, transiting mainly under sail power from May to June 1819. In spite of this historic voyage, the great space taken up by her large engine and its fuel at the expense of cargo, and the public's anxiety over embracing her revolutionary steam power, kept Savannah from being a commercial success as a steamship. Originally laid down as a sailing packet, she was, following a severe and unrelated reversal of the financial fortunes of her owners, converted back into a sailing ship shortly after returning from Europe.
USS Fort Jackson was a wooden sidewheel steamer in the United States Navy during the American Civil War. She was successful in enforcing the Union blockade of Confederate ports, capturing five ships carrying contraband. She participated in the battles for Fort Fisher, which effectively closed the port of Wilmington, North Carolina to the Confederacy. Most notably, the surrender of Confederate forces in Texas was signed aboard the ship, formally ending the Civil War in that portion of the country.
USS Santiago de Cuba was a side-wheel steamship acquired by the Union Navy during the first year of the American Civil War. She was outfitted as a gunboat with powerful 20-pounder rifled guns and 32-pounder cannon and was assigned to the Union blockade of the Confederate States of America. She was notably successful in this role, capturing several blockade runners. Her last major action of the war was the assault on Fort Fisher, during which seven of her crew won the Medal of Honor.
Stephen Decatur Trenchard was a rear admiral in the United States Navy. He was present at the Battle of Taku Forts in 1859, and commanded the supply ship and gunboat Rhode Island throughout the American Civil War, seeing action at both Battles of Fort Fisher. He later commanded the North Atlantic Squadron.
Sankaty was a propeller-driven steamer that served as a ferry to Martha's Vineyard and Nantucket in Massachusetts; in Rockland, Maine; Stamford, Connecticut and Oyster Bay, Long Island in the United States from 1911 to 1940. During World War II, the ship was requisitioned by the Royal Canadian Navy for service as a minelayer and maintenance vessel along the Canadian Atlantic coast. Following the war the ship returned to a ferry, working the Wood Islands, Prince Edward Island and Caribou, Nova Scotia route in Canada from 1947 until 1964. While being towed to the breaker's yard, the ship sank off the coast of Nova Scotia on October 27, 1964.
USS Underwriter was a 341-ton sidewheel steamer that was purchased for military use by the Union Navy during the American Civil War.
USS De Soto was a fast wooden-hulled sidewheel steamship that saw service as a U.S. Navy gunboat during the American Civil War.
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II. Reciprocating steam engines were progressively replaced in marine applications during the 20th century by steam turbines and marine diesel engines.
The Allaire Iron Works was a leading 19th-century American marine engineering company based in New York City. Founded in 1816 by engineer and philanthropist James P. Allaire, the Allaire Works was one of the world's first companies dedicated to the construction of marine steam engines, supplying the engines for more than 50% of all the early steamships built in the United States.
Henry Eckford was a small passenger-cargo steamboat built in New York in 1824. She was the first steam vessel in the world to be installed with a compound engine, almost fifty years before the technology would become widely adopted for marine use.
SS Archimedes was a steamship built in Britain in 1839. She was the world's first steamship to be driven successfully by a screw propeller.
The Comboyne was a wooden screw steamer built in 1911 at Tuncurry, that was wrecked when it struck an object whilst carrying timber to Wollongong and was lost at approximately 1 mile (1.6 km) off Bass Point, Shellharbour, New South Wales on 27 November 1920.
PS Lily was a passenger paddle steamer operated by the London and North Western Railway from 1880 to 1900.
SS Violet was a passenger paddle steamer operated by the London and North Western Railway from 1880 to 1902.
Franklin Jeremiah Drake was a Rear Admiral in the United States Navy. He fought in the American Civil War and the United States expedition to Korea.
Rear Admiral George Henry Cooper was an officer in the United States Navy. During his long naval career, he served on the African Slave Trade Patrol, and fought in the Second Seminole War, the Mexican War, the American Civil War, and the Korean Expedition, and rose to command of the North Atlantic Squadron.
The Herald was an iron paddle steamer imported as frames from the United Kingdom and assembled in 1855 by Richard Johnson in Sydney Harbour, New South Wales, Australia, where she was registered. The Herald is one of the earliest iron paddle wheel steamers built in Australia, where she operated within Sydney Harbour. She was initially used on the fledgling North Shore route between Dawes Point and Blues Point by the newly formed North Shore Steam Company; however, due to not enough traffic to make her financially viable, she often performed tug duties. Eventually the North Shore Steam Company was wound up; the vessel was put up for sale but continued picking up business wherever it was available, operating as a tug, ferry, excursion boat and cargo vessel.
This group of vessels were originally slated to be built to the Sampson designed steam vessel; however, the Admiralty on 9 May 1845, ordered the first pair as First-Class screw sloops to be built from a design of Sir William Symonds, Surveyor of the Navy. This design would become known as the Conflict-class sloop. These would be 10-gun vessels with 400 NHP engines. The second pair of vessels were ordered on 26 March 1846 but after their keels were laid at Pembroke Dockyard, their construction was suspended in September 1846 then cancelled five years later, on 4 April 1851. Both completed ships served in the Baltic during the Crimean war, and Desperate briefly served as a store ship to Edward Augustus Inglefield's Arctic expedition. They had both been broken up by 1865.
HMS Dee was the first paddle steamer ordered for the Royal Navy, designed to carry a significant armament. She was ordered on 4 April 1827 from Woolwich Dockyard. She was designed by Sir Robert Seppings, Surveyor of the Navy and modified by Oliver Lang. This vessel was considered as new construction as a previous vessel ordered as a flush deck Cherokee-class brig in 1824, had been renamed African in May 1825. She was initially classed as a steam vessel (SV), and in 1837 reclassified as a steam vessel class 2 (SV2). She was converted to a troopship in May 1842 and as a second class sloop in 1846. She was converted into a storeship in 1868. She was broken at Sheerness in 1871.
