USS Winnebago (1863)
USS ''Winnebago'' was a double-turret river monitor, named for the Winnebago tribe of Siouan Indians, built for the Union Navy during the American Civil War. The ship participated in the Battle of Mobile Bay in 1864, during which she was lightly damaged, and the bombardments of Forts Gaines and Morgan as Union troops besieged the fortifications defending the bay. In early 1865, ''Winnebago'' again supported Union forces during the Mobile Campaign as they attacked Confederate fortifications defending the city of Mobile, Alabama. She was placed in reserve after the end of the war and sold in 1874. Description ''Winnebago'' was long overall and had a beam of . The ship had a depth of hold of Canney, p. 114 and a draft of . She was 970 tons burthen and displaced .Chesneau & Kolesnik, p. 123 Her crew numbered 138 officers and enlisted men.Silverstone, p. 111 The ship was powered by two 2-cylinder horizontal non-condensing steam engines, each driving two propellers, using st ...

Union Navy
The Union Navy was the United States Navy (USN) during the American Civil War, when it fought the Confederate States Navy (CSN). The term is sometimes used carelessly to include vessels of war used on the rivers of the interior while they were under the control of the United States Army, also called the Union Army. Wartime missions The primary missions of the Union Navy were: :1. Maintain the blockade of Confederate ports by restraining all blockade runners; declared by President Lincoln on April 19, 1861, and continued until the end of the Rebellion. :2. Meet in combat the war vessels of the CSN. :3. Carry the war to places in the seceded states that were inaccessible to the Union Army, but could be reached by water. :4. Support the Army by providing both gunfire support and rapid transport and communications on the rivers of the interior. Administrative organization The system of naval bureaus was revised in the summer of 1862. Some of the older bureaus were rearranged or had ...

Muzzle-loading
A muzzleloader is any firearm into which the projectile and the propellant charge is loaded from the muzzle of the gun (i.e., from the forward, open end of the gun's barrel). This is distinct from the modern (higher tech and harder to make) designs of breech-loading firearms. The term "muzzleloader" applies to both rifled and smoothbore type muzzleloaders, and may also refer to the marksman who specializes in the shooting of such firearms. The firing methods, paraphernalia and mechanism further divide both categories as do caliber (from cannons to small-caliber palm guns). Modern muzzleloading firearms range from reproductions of sidelock, flintlock and percussion long guns, to in-line rifles that use modern inventions such as a closed breech, sealed primer and fast rifling to allow for considerable accuracy at long ranges. Modern mortars use a shell with the propelling charge and primer attached at the base. Unlike older muzzleloading mortars, which were loaded the same way ...

Smoothbore
A smoothbore weapon is one that has a barrel without rifling. Smoothbores range from handheld firearms to powerful tank guns and large artillery mortars. History Early firearms had smoothly bored barrels that fired projectiles without significant spin. To minimize inaccuracy-inducing tumbling during flight, their projectiles required an aerodynamically uniform shape, such as a sphere. However, surface imperfections on the projectile and/or the barrel will cause even a sphere to rotate randomly during flight, and the Magnus effect will curve it off the intended trajectory when spinning on any axis not parallel to the direction of travel. Rifling the bore surface with spiral grooves or polygonal valleys imparts a stabilizing gyroscopic spin to a projectile that prevents tumbling in flight. Not only does this more than counter Magnus-induced drift, but it allows a longer, more streamlined round with greater sectional density to be fired from the same caliber barrel, ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A ...

Glossary Of Nautical Terms (A-L)
This glossary of nautical terms is an alphabetical listing of terms and expressions connected with ships, shipping, seamanship and navigation on water (mostly though not necessarily on the sea). Some remain current, while many date from the 17th to 19th centuries. The word nautical derives from the Latin ''nauticus'', from Greek ''nautikos'', from ''nautēs'': "sailor", from ''naus'': "ship". Further information on nautical terminology may also be found at Nautical metaphors in English, and additional military terms are listed in the Multiservice tactical brevity code article. Terms used in other fields associated with bodies of water can be found at Glossary of fishery terms, Glossary of underwater diving terminology, Glossary of rowing terms, and Glossary of meteorology This glossary of meteorology is a list of terms and concepts relevant to meteorology and atmospheric science, their sub-disciplines, and related fields.

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 ' ...

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 A marina (from Spanish , Portuguese and Italian : ''marina'', "coast" or "shore") is a dock or basin with moorings and supplies for yachts and small boats. A marina differs from a port in that a marina does not handle large passenger ships o ... 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 oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reserve Fleet
A reserve fleet is a collection of naval vessels of all types that are fully equipped for service but are not currently needed; they are partially or fully decommissioned. A reserve fleet is informally said to be "in mothballs" or "mothballed"; an equivalent expression in unofficial modern US naval usage is "ghost fleet". In earlier times, especially in British usage, the ships were said to be "laid up in ordinary". Overview Such ships are held in reserve against a time when it may be necessary to call them back into service. They are usually tied up in backwater areas near naval bases or shipyards in order to speed the reactivation process. They may be modified for storage during such a period, for instance by having rust-prone areas sealed off or wrapped in plastic or, in the case of sailing warships, the masts removed. While being held in the reserve fleet, ships typically have a minimal crew (known informally as a skeleton crew) to ensure that they stay in somewhat usable ...

Mobile, Alabama
Mobile ( , ) is a city and the county seat of Mobile County, Alabama, United States. The population within the city limits was 187,041 at the 2020 census, down from 195,111 at the 2010 census. It is the fourth-most-populous city in Alabama, after Huntsville, Birmingham, and Montgomery. Alabama's only saltwater port, Mobile is located on the Mobile River at the head of Mobile Bay on the north-central Gulf Coast. The Port of Mobile has always played a key role in the economic health of the city, beginning with the settlement as an important trading center between the French colonists and Native Americans, down to its current role as the 12th-largest port in the United States.Drechsel, Emanuel. ''Mobilian Jargon: Linguistic and Sociohistorical Aspects of a Native American Pidgin''. New York: Oxford University Press, 1997. Mobile is the principal municipality of the Mobile metropolitan area.

Mobile Campaign
A mobile campaign is a campaign, usually marketing, advertising, or public relations-related, through which organizations contact their audience through SMS (text messaging). This form of campaigning allows organizations to reach out and establish relationships with an audience in a more individualized, intimate way. The foundational function of mobile campaigns is regularly referred to as mobile marketing. A campaign's goal can have varied consumer consumption objectives including flashing (showing an image), informing (informational text / product info) or engaging (response or click required). Mobile campaigns have developed from the periphery of advertising to being an integral part of an effective marketing strategy. Online advertising is the second largest advertising spend at $113 billion, next to television's $196.5 billion (2013 figures). Near the introduction of mobile campaigns, they were primarily created to boost the impact of primary campaigns. A good example of one ...

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 Fo ...
