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 incorrectly 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.
A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels. Steamboats sometimes use the prefix designation SS, S.S. or S/S or PS ; however, these designations are most often used for steamships.
USSKeystone State was a wooden sidewheel steamer that served in the Union Navy during the American Civil War. She was a fast ship for her day and was used effectively to blockade Confederate ports on the Atlantic coast. She participated in the capture or destruction of 17 blockade runners. In addition to her military service, Keystone State had a lengthy commercial career before the war. Renamed San Francisco, she also sailed commercially after the war. The ship was built in 1853 and scrapped in 1874.
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.
The Pacific Mail Steamship Company was founded April 18, 1848, as a joint stock company under the laws of the State of New York by a group of New York City merchants. Incorporators included William H. Aspinwall, Edwin Bartlett, Henry Chauncey, Mr. Alsop, G.G. Howland and S.S. Howland.
The Illawarra Steam Navigation Company was a shipping company that serviced the south coast of New South Wales, Australia from 1858 to the early 1950s. It was formed through the amalgamation of the General Steam Navigation Company, the Kiama Steam Navigation Company and the Shoalhaven Steam Navigation Company, each of whom serviced parts of the south coast with their respective vessels. After merging, the new company held a near monopoly in regard to shipping on the south coast, and their fleet visited every significant port between Sydney and the border of Victoria. The company transported both passengers and a range of produce, including livestock, and hence it became known as the 'Pig and Whistle Line': it was said that ships would wait an hour for a pig but not a minute for a passenger.
Estrella was a paddle steamship built by Samuda Brothers in London in 1853 for the Magdalena Steam Navigation Company's commercial services in present-day Colombia. In 1862 she was sold to United States owners and briefly used as a Union Army transport before being acquired by the Union Navy. She served as the armed steamship USS Estrella during the remainder of the American Civil War, carrying three heavy guns as well as two howitzers for shore bombardment.
The General Screw Steam Shipping Company was a British company established in 1848 by James Laming, who had for about 30 years owned sailing ships travelling between England and the Netherlands.
Active was a survey ship that served in the United States Coast Survey, a predecessor of the United States Coast and Geodetic Survey, from 1852 to 1861. Active served on the U.S. West Coast. She conducted the Coast Survey's first reconnaissance from San Francisco, California, to San Diego, California, in 1852. Active sometimes stepped outside her normal Coast Survey duties to support U.S. military operations, serving as a troop transport and dispatch boat during various wars with Native Americans and during the San Juan Islands "Pig War" with the United Kingdom in 1859. She also rushed Union troops to Los Angeles, California, in 1861 during the early stages of the American Civil War.
USC&GS Arago was a survey ship that served in the United States Coast Survey from 1854 to 1878 and in the United States Coast and Geodetic Survey from 1878 to 1881. From October 1861 into 1863 Arago was at times attached to the Navy's South Atlantic Blockading Squadron off South Carolina to provide hydrographic support. She was the first ship of the Coast Survey or Coast and Geodetic Survey to bear the name.
SS Baltic was a wooden-hulled sidewheel steamer built in 1850 for transatlantic service with the American Collins Line. Designed to outclass their chief rivals from the British-owned Cunard Line, Baltic and her three sister ships—Atlantic, Pacific and Arctic—were the largest, fastest and most luxurious transatlantic steamships of their day.
SS California was one of the first steamships to steam in the Pacific Ocean and the first steamship to travel from Central America to North America. She was built for the Pacific Mail Steamship Company which was founded April 18, 1848 as a joint stock company in the State of New York by a group of New York City merchants: William H. Aspinwall, Edwin Bartlett, Henry Chauncey, Mr. Alsop, G.G. Howland and S.S. Howland. She was the first of three steamboats specified in a government mail contract to provide mail, passenger, and freight service from Panama to and from San Francisco and Oregon.
The California Steam Navigation Company was formed in 1854 to consolidate competing steamship companies in the San Francisco Bay Area and on the Sacramento and San Joaquin Rivers. It was successful in this effort and established a profitable near-monopoly which it maintained by buying out or bankrupting new competitors. In response to the Fraser Canyon gold rush and economic growth in the Pacific Northwest, the company expanded to ocean routes from San Francisco north to British Columbia. Similarly, as California's economy grew, the company offered service from San Francisco south to San Pedro and San Diego. It exited these markets in 1867 when competition drove prices to unprofitable levels. While the California Steam Navigation Company was successful throughout its life in suppressing steamboat competition on its core Bay Area and river routes, it could not control the rise of railroads. These new competitors reduced the company's revenue and profit. Finally, in 1871, the company's assets were purchased by the California Pacific Railroad, and the corporation was dissolved.
The Arago was a wooden hulled, brig-rigged, sidewheel steamer built in 1855 by Westervelt & Sons at New York, New York. Chartered by the Union Army in the Army Transport Service, during the American Civil War for use as a troop transport and in operation with the South Atlantic Blockading Squadron throughout the war, Arago was the ship that returned the United States flag to Fort Sumter in April 1865. Returned to transatlantic passenger and freight service after the Civil War, she was sold to the Peruvian government in 1869.
Orizaba was one of the first ocean-going steamships in commercial service on the west coast of North America and one of the last side-wheelers in regular use. Her colorful career spanned the business intrigues of Cornelius Vanderbilt, civil unrest in Mexico and Nicaragua, and the Fraser River gold rush. The ship was particularly important to Southern California ports, where she called for roughly the last 20 years of her service.
Ajax was a wooden, propeller-driven steamship built in 1864. She provided logistical support to the Union Army on the Atlantic coast during the American Civil War. After the war she was sent to San Francisco where she provided freight and passenger services between that city and other ports on the Pacific coast. She provided the first scheduled steamship service between the United States and Hawaii.
SS Mexique was a French transatlantic ocean liner of the Compagnie Générale Transatlantique (CGT). She was launched in 1914 as Île de Cuba but when she was completed in 1915 she was renamed Lafayette.
Royal Mail Steam Ship Arabia was an ocean liner operated by Cunard. It was the last wooden-hulled ship built for the Cunard Line, built in 1852 in Greenock, Scotland. On January 1, 1853, it departed on its maiden voyage with 60 passengers and 1,200 tons of coal. RMS Arabia was a luxurious ship during its time, with the saloon having a stained glass dome and crimson velvet sofas, and steam heating throughout. She was reported to be the first ocean liner with a separate children's nursery and playroom.
Star of the South was a wooden-hulled, propeller-driven steamship launched in 1853. She was one of the first mechanically reliable and economically profitable propeller-driven steamships. Her success foretold the end of paddlewheel propulsion on ocean-going steamships.
Daniel Webster was an American steamboat built in 1853 for passenger service on the coast of Maine. When new, she was the largest and fastest steamer in Maine coastal service, and widely considered to be the finest.
