SS Montanan
SS ''Montanan'' was a cargo ship built in 1912 for the American-Hawaiian Steamship Company. During World War I service for the United States Army Transport Service, she was known as USAT ''Montanan''. ''Montanan'' was built by the Maryland Steel Company as one of eight sister ships for the American-Hawaiian Steamship Company, and was employed in inter-coastal service via the Isthmus of Tehuantepec and the Panama Canal after it opened. In World War I, USAT ''Montanan'' carried cargo and animals to France, and was in the first American convoy to sail to France after the United States entered the war in April 1917. USAT ''Montanan'' was torpedoed and sunk by west of Le Verdon-sur-Mer, France, while it took part in another eastbound convoy in August 1918, Of the 86 men aboard the ship, 81 were rescued by a convoy escort; five men died in the attack. Design and construction In September 1911, the American-Hawaiian Steamship Company placed an order with the Maryland Steel Company ...

Isthmus Of Tehuantepec
The Isthmus of Tehuantepec () is an isthmus in Mexico. It represents the shortest distance between the Gulf of Mexico and the Pacific Ocean. Before the opening of the Panama Canal, it was a major overland transport route known simply as the Tehuantepec Route. The name is taken from the town of Santo Domingo Tehuantepec in the state of Oaxaca; this was derived from the Nahuatl term (" jaguar mountain"). Geography The isthmus includes the part of Mexico lying between the 94th and 96th meridians west longitude, or the southeastern parts of Veracruz and Oaxaca, including small areas of Chiapas and Tabasco. The states of Tabasco and Chiapas are east of the isthmus, with Veracruz and Oaxaca on the west. At its narrowest point, the isthmus is across from gulf to gulf, or to the head of Laguna Superior on the Pacific coast. The Sierra Madre del Sur mountain range breaks down at this point into a broad, plateau-like ridge, whose elevation, at the highest point reache ...

Coatzacoalcos
Coatzacoalcos () is a major port city in the southern part of the Mexican state of Veracruz, mostly on the western side of the Coatzacoalcos River estuary, on the Bay of Campeche, on the southern Gulf of Mexico coast. The city serves as the municipal seat of the municipality of the same name. It is the state's third largest city, after Veracruz City and Xalapa. Etymology Coatzacoalcos comes from a Nahuatl word meaning "site of the Snake" or "where the snake hides." According to the legend, this is where the god Quetzalcoatl made his final journey to the sea in around 999 and he made his promise to return. History Coatzacoalcos sits within the Olmec heartland. Excavations in 2008 for a tunnel under the Coatzacoalcos River indicate a substantial pre-Hispanic population. By the time of the Spanish arrival the area was under Mayan influence. In 1522, Hernán Cortés ordered Gonzalo de Sandoval to fund a settlement near Guazacualco. Sandoval named it Villa del Espíritu Sa ...

Boiler
A boiler is a closed vessel in which fluid (generally water) 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. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration i ...

West Coast Of The United States
The West Coast of the United States, also known as the Pacific Coast, Pacific states, and the western seaboard, is the coastline along which the Western United States meets the North Pacific Ocean. The term typically refers to the contiguous U.S. states of California, Oregon, and Washington, but sometimes includes Alaska and Hawaii, especially by the United States Census Bureau as a U.S. geographic division. Definition There are conflicting definitions of which states comprise the West Coast of the United States, but the West Coast always includes California, Oregon, and Washington as part of that definition. Under most circumstances, however, the term encompasses the three contiguous states and Alaska, as they are all located in North America. For census purposes, Hawaii is part of the West Coast, along with the other four states. ''Encyclopædia Britannica'' refers to the North American region as part of the Pacific Coast, including Alaska and British Columbia. Although ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ' ...

Ship Naming And Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is t ...

Deadweight Tonnage
Deadweight tonnage (also known as deadweight; abbreviated to DWT, D.W.T., d.w.t., or dwt) or tons deadweight (DWT) is a measure of how much weight a ship can carry. It is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew. DWT is often used to specify a ship's maximum permissible deadweight (i.e. when it is fully loaded so that its Plimsoll line is at water level), although it may also denote the actual DWT of a ship not loaded to capacity. Definition Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the volumetric measures of gross tonnage or net tonnage (and the legacy measures gross register tonnage and net register tonnage). Deadweight tonnage was historically expressed in long tonsOne long ton (LT) is but is now usually given internationally i ...
