A ship of the line was a type of naval warship constructed from the 17th century to the mid-19th century. The ship of the line was designed for the naval tactic known as the line of battle, which depended on the two columns of opposing warships maneuvering to fire with the cannons along their broadsides. In conflicts where opposing ships were both able to fire from their broadsides, the opponent with more cannons—and therefore more firepower—typically had an advantage. Since these engagements were almost invariably won by the heaviest ships carrying the most powerful guns, the natural progression was to build sailing vessels that were the largest and most powerful of their time.
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.
A boiler is a closed vessel in which fluid is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation.
A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans.
An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom.
A fishing trawler is a commercial fishing vessel designed to operate fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously.
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure (HP) cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure (LP) cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam.
Bentwood objects are those made by wetting wood, then bending it and letting it harden into curved shapes and patterns.
The Isle of Man Steam Packet Company Limited is the oldest continuously operating passenger shipping company in the world, celebrating its 190th anniversary in 2020.
In woodworking, a knee is a natural or cut, curved piece of wood. Knees, sometimes called ships knees, are a common form of bracing in boat building and occasionally in timber framing. A knee rafter in carpentry is a bent rafter used to gain head room in an attic.
Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or engine turning a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems.
USNS Bowditch (T-AGS-21) was the lead ship of her class of oceanographic survey ships for the United States Navy. Launched as the SS South Bend Victory in 1945, Maritime Commission hull number MCV 694, a type VC2-S-AP3 Victory ship, she was named for Nathaniel Bowditch, the second U.S. Navy vessel named in his honor. The ship was acquired by the Navy in August 1957 and converted to an AGS at Charleston Naval Shipyard. Named Bowditch on 8 August 1957 and placed in service 8 October 1958 for operation by the Military Sea Transportation Service (MSTS).
The era of steamboats on the Arrow Lakes and adjoining reaches of the Columbia River is long-gone but was an important part of the history of the West Kootenay and Columbia Country regions of British Columbia. The Arrow Lakes are formed by the Columbia River in southeastern British Columbia. Steamboats were employed on both sides of the border in the upper reaches of the Columbia, linking port-towns on either side of the border, and sometimes boats would be built in one country and operated in the other. Tributaries of the Columbia include the Kootenay River which rises in Canada, then flows south into the United States, then bends north again back into Canada, where it widens into Kootenay Lake. As with the Arrow Lakes, steamboats once operated on the Kootenay River and Kootenay Lake.
SS Dwinsk was a British-flagged ocean liner sunk by SM U-151 in World War I. The ship was previously the third Rotterdam for the Holland America Line, C.F. Tietgen for the Scandinavian America Line, and, as Dwinsk, for the Russian American Line. The ship was put under Cunard Line management in 1917, and sailed under the British flag until sunk on 18 June 1918.
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.
Steam bending is a woodworking technique where wood is exposed to steam to make it pliable. Heat and moisture from steam can soften wood fibres enough so they can be bent and stretched, and when cooled down they will hold their new shape.
The Battle of Tonkin River was a major naval battle fought in northern Vietnam between the pirates of Shap Ng-tsai and the British Royal Navy with aid from the Qing Chinese navy and the Tonkinese. The 1849 expedition led to the destruction of Shap Ng-tsai's fleet and the loss of over 2,000 men. The battle occurred over a three-day period at the mouth of the Tonkin River, near present-day Hai Phong.
Portland is a sternwheel steamboat built in 1947 for the Port of Portland, Oregon, in the United States.
SteamOS is the primary operating system for the Steam Machine gaming platform by Valve. It is based on the Debian distribution of Linux.
