SM UC-63
SM ''UC-63'' was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy (german: Kaiserliche Marine) during World War I. The U-boat was ordered on 12 January 1916, laid down on 3 April 1916, and was launched on 6 January 1917. She was commissioned into the German Imperial Navy on 30 January 1917 as SM ''UC-63''."SM" stands for ''Seiner Majestäts'' ( en, His Majesty's) and combined with "U" for ''Unterseeboot'' translates as "His Majesty's Submarine". In nine patrols ''UC-63'' was credited with sinking 36 ships, either by torpedo or by mines laid. ''UC-63'' was torpedoed and sunk by off Goodwin Sands on 1 November 1917; only one crewman survived the sinking. Design A German Type UC II submarine, ''UC-63'' had a displacement of when at the surface and while submerged. She had a length overall of , a beam of , and a draught of . The submarine was powered by two six-cylinder four-stroke diesel engines each producing (a total of ), two electric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Empire
The German Empire (),Herbert Tuttle wrote in September 1881 that the term "Reich" does not literally connote an empire as has been commonly assumed by English-speaking people. The term literally denotes an empire – particularly a hereditary empire led by an emperor, although has been used in German to denote the Roman Empire because it had a weak hereditary tradition. In the case of the German Empire, the official name was , which is properly translated as "German Empire" because the official position of head of state in the constitution of the German Empire was officially a "presidency" of a confederation of German states led by the King of Prussia who would assume "the title of German Emperor" as referring to the German people, but was not emperor of Germany as in an emperor of a state. –The German Empire" ''Harper's New Monthly Magazine''. vol. 63, issue 376, pp. 591–603; here p. 593. also referred to as Imperial Germany, the Second Reich, as well as simply Germany, ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armed Trawler Ethel & Millie
The Armed trawler ''Ethel & Millie'' was a British auxiliary warship which served during World War I. She was built in 1908 as the fishing smack ''Ethel & Millie'', operating from Lowestoft and registered as LT 200. In early 1917 she was armed for defence against U-boat attack, and fought two actions against them. She was sunk in action on 15 August 1917. Background '' Ethel & Millie'' was a 58-ton trawling smack, built and registered at Lowestoft in 1908. Prior to the First World War she had an uneventful career as part of the fishing fleet there, operating out into the North Sea fishing grounds. In 1917 German U-boats had started to attack British trawlers, and in response to this, a number of trawlers were armed for self defence. ''Ethel & Millie'' was one of these vessels, being equipped with a 6-pounder gun and assigned a naval rating as gunner. In this manner she entered service in February 1917, under the command of skipper Wharton, and carrying the name ''Boy Alfred'' ...

Armed Trawler Nelson
Armed trawler ''Nelson'' was a British auxiliary warship which served during World War I. She was built in 1905 as the fishing smack ''G&E'', operating from Lowestoft and registered as LT 649. In 1915 she was armed for defence against U-boat attack, and fought several actions against them. She was sunk in action on 15 August 1917. This action was fought between a German U-boat (believed to be ) and two trawlers, ''Nelson'' and , off the English coast. Background ''G&E'' was a dandy-rigged smack of 49 net registered tons, built at Porthleven, Cornwall in 1905 and registered at Lowestoft. She was built for Frederick Moxey of Lowestoft and was registered there as LT 649, operating in the North Sea fishing grounds. In 1915, as part of the Imperial German Navy's U-boat campaign of unrestricted submarine warfare German U-boats had started to attack British trawlers (which had previously been protected by the 1907 Naval Convention) in the North Sea. In response to this, fisherm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Action Of 15 August 1917
The action of 15 August 1917 was a naval engagement which occurred during the First World War. The action was fought between a German U-boat (believed to be ) and two naval trawlers, ''Nelson'' and '' Ethel & Millie'', in the North Sea. Background As part of the Imperial German Navy's U-boat campaign of unrestricted submarine warfare German U-boats had started to attack British trawlers (which had previously been protected by the 1907 Naval Convention) in the North Sea. In response to this, fishermen had requested weapons for self-defence, and a number of trawlers been equipped with deck guns, and had gunners assigned to man them. These vessels were generally skippered by men who were members of the Royal Navy Reserve, but were left to continue fishing, and act on their own initiative if attacked, rather than coming under Royal Navy command. Action On 15 August 1917, a number of Lowestoft trawlers were fishing in the North Sea, off the Jim Howe bank. Among them were the armed ...

Propeller Shaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-19th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draught (ship)
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 (ship)
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 ...

Goodwin Sands
Goodwin Sands is a sandbank at the southern end of the North Sea lying off the Deal coast in Kent, England. The area consists of a layer of approximately depth of fine sand resting on an Upper Chalk platform belonging to the same geological feature that incorporates the White Cliffs of Dover. The banks lie between above the low water mark to around below low water, except for one channel that drops to around below. Tides and currents are constantly shifting the shoals. More than 2,000 ships are believed to have been wrecked upon the Goodwin Sands because they lie close to the major shipping lanes through the Straits of Dover. The few miles between the sands and the coast is also a safe anchorage, known as The Downs, used as a refuge from foul weather. Due to the dangers, the area – which also includes Brake Bank – is marked by numerous lightvessels and buoys. Notable shipwrecks include in 1703, in 1740, the in 1914, and the South Goodwin Lightship, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
