USS Tecumseh (1863)
USS ''Tecumseh'' was a built for the United States Navy during the American Civil War. Although intended for forthcoming operations against Confederate fortifications guarding Mobile Bay with Rear Admiral David Farragut's West Gulf Blockading Squadron, ''Tecumseh'' was temporarily assigned to the James River Flotilla in April 1864. The ship helped to plant obstacles in the river and engaged Confederate artillery batteries in June. ''Tecumseh'' was sunk on 5 August during the Battle of Mobile Bay when she struck a mine. The ship capsized and rests upside down northwest of Fort Morgan. The Smithsonian Institution surveyed her wreck in 1967 with the intent of raising it, but ultimately decided against the project when proffered funding was withdrawn. Several other plans to raise the wreck have been made, but all have fallen through. Description and construction The ship was long overall, had a beam of and had a maximum draft of . ''Tecumseh'' had a tonnage of 1,034 tons burthen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individ ...

American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

Smithsonian Institution
The Smithsonian Institution ( ), or simply the Smithsonian, is a group of museums and education and research centers, the largest such complex in the world, created by the U.S. government "for the increase and diffusion of knowledge". Founded on August 10, 1846, it operates as a trust instrumentality and is not formally a part of any of the three branches of the federal government. The institution is named after its founding donor, British scientist James Smithson. It was originally organized as the United States National Museum, but that name ceased to exist administratively in 1967. Called "the nation's attic" for its eclectic holdings of 154 million items, the institution's 19 museums, 21 libraries, nine research centers, and zoo include historical and architectural landmarks, mostly located in the District of Columbia. Additional facilities are located in Maryland, New York, and Virginia. More than 200 institutions and museums in 45 states,States without Smithsonian ...

Fort Morgan (Alabama)
Fort Morgan is a historic masonry pentagonal bastion fort at the mouth of Mobile Bay, Alabama, United States. Named for Revolutionary War hero Daniel Morgan, it was built on the site of the earlier Fort Bowyer, an earthen and stockade type fortification involved in the final land battles of the War of 1812. Construction was completed in 1834 and it received its first garrison in March of the same year. Fort Morgan is at the tip of Mobile Point at the western terminus of State Route 180 (Alabama). It and Dauphin Island, on which Fort Gaines is situated, enclose Mobile Bay. The Alabama Historical Commission maintains the site. War of 1812 After the departure of the Spanish from Mobile in April 1813, the Americans built an earth and wood redoubt on Mobile Point, ultimately naming it Fort Bowyer after Col. John Bowyer, who completed the construction before leaving in 1814. In September 1814 the fort withstood a British naval and land attack, known as the First Battle of Fort ...

Capsized
Capsizing or keeling over occurs when a boat or ship is rolled on its side or further by wave action, instability or wind force beyond the angle of positive static stability or it is upside down in the water. The act of recovering a vessel from a capsize is called righting. Capsize may result from broaching, , loss of stability due to cargo shifting or flooding, or in high speed boats, from turning too fast. If a capsized vessel has enough flotation to prevent sinking, it may recover on its own in changing conditions or through mechanical work if it is not stable inverted. Vessels of this design are called self-righting. Small vessels In dinghy sailing, a practical distinction can be made between being knocked down (to 90 degrees; on its beam-ends, figuratively) which is called a capsize, and being inverted, which is called being turtled. Small dinghies frequently capsize in the normal course of use and can usually be recovered by the crew. Some types of dinghy are occasi ...

Artillery Batteries
In military organizations, an artillery battery is a unit or multiple systems of artillery, mortar systems, rocket artillery, multiple rocket launchers, surface-to-surface missiles, ballistic missiles, cruise missiles, etc., so grouped to facilitate better battlefield communication and command and control, as well as to provide dispersion for its constituent gunnery crews and their systems. The term is also used in a naval context to describe groups of guns on warships. Land usage Historically the term "battery" referred to a cluster of cannon in action as a group, either in a temporary field position during a battle or at the siege of a fortress or a city. Such batteries could be a mixture of cannon, howitzer, or mortar types. A siege could involve many batteries at different sites around the besieged place. The term also came to be used for a group of cannon in a fixed fortification, for coastal or frontier defence. During the 18th century "battery" began to be used as an ...

James River Flotilla
The Union blockade in the American Civil War was a naval strategy by the United States to prevent the Confederacy from trading. The blockade was proclaimed by President Abraham Lincoln in April 1861, and required the monitoring of of Atlantic and Gulf coastline, including 12 major ports, notably New Orleans and Mobile. Those blockade runners fast enough to evade the Union Navy could carry only a small fraction of the supplies needed. They were operated largely by foreign citizens, making use of neutral ports such as Havana, Nassau and Bermuda. The Union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war. Proclamation of blockade and legal implications On April 19, 1861, President Lincoln issued a ''Proclamation of Blockade Against Southern Ports'': Whereas an insurrection against the Government of the United States has broken out in the States of South Carolina, Georgia, Alabama, Florida, Mississippi, Louisiana, ...

David Farragut
David Glasgow Farragut (; also spelled Glascoe; July 5, 1801 – August 14, 1870) was a flag officer of the United States Navy during the American Civil War. He was the first rear admiral, vice admiral, and admiral in the United States Navy. Farragut, 1879, p. 3 Hickman, 2010, p. 216 He is remembered for his order at the Battle of Mobile Bay, usually paraphrased as "Damn the torpedoes, full speed ahead" in U.S. Navy tradition. Stein, 2005, p. 5 Spears, 1905, p. 328 Born near Knoxville, Tennessee, Farragut was fostered by naval officer David Porter after the death of his mother. When he was 11 years old, Farragut served in the War of 1812 under the command of his adoptive father. He received his first command in 1823, at the age of 22, and went on to participate in anti-piracy operations in the Caribbean Sea. He then served in the Mexican–American War under the command of Matthew C. Perry, participating in the blockade of Tuxpan. After the war, he oversaw the construction of ...
