SS Robin Moor
SS ''Robin Moor'' was a United States cargo steamship that was built in 1919 and sunk by a U-boat in May 1941, several months before the US entered World War II. The U-boat allowed the passengers and crew to launch her lifeboats and abandon ship with no loss of life. However, the sinking of a neutral ship in an area considered until then to be relatively safe from U-boats, and the plight of her crew and passengers, caused a political incident in the United States. The attack caused many to question the motives of ''U-69''s commander, Jost Metzler as Hitler himself, preparing for his June 1941 invasion of Russia, had expressly ordered his Navy chief, Admiral Erich Raeder: "...in the next weeks all attacks on naval vessels in the closed area should cease..." Hitler did not wish to provoke America into joining with Britain in its fight against Germany. Building, names, and details The ship was a Design 1022 Hog Islander, built by the American International Shipbuilding Corporati ...

Jost Metzler
Jost Metzler (26 February 1909 – 29 September 1975) was a German submarine commander during World War II. He commanded the U-boats and , and was recipient of the Knight's Cross of the Iron Cross of Nazi Germany. Career Metzler joined the ''Kriegsmarine'' in October 1933, after spending eight years in the merchant marine. He served on the torpedo boat ''T-196'' and on several minesweepers. After 13 patrols on the minesweeper ''Grille'', he transferred to the U-boat arm in April 1940, commissioning in November 1940. On his first patrol, sailing from Kiel to St. Nazaire in early 1941, he sank three ships for a total of . On his second patrol south-west of Iceland, he sank a single ship of and damaged another. Metzler's third patrol on ''U-69'' was the most successful. He laid 16 mines in the harbour of Lagos, Nigeria, where they later sank a British steamer. He then sank another five ships for a total of . Metzler developed renal colic a few days after leaving St. Nazaire on h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portuguese Mozambique
Portuguese Mozambique ( pt, Moçambique) or Portuguese East Africa (''África Oriental Portuguesa'') were the common terms by which Mozambique was designated during the period in which it was a Portuguese Empire, Portuguese colony. Portuguese Mozambique originally constituted a string of Portuguese possessions along the south-east African coast, and later became a unified colony, which now forms the Republic of Mozambique. Portuguese trading settlements—and later, colonies—were formed along the coast and into the Zambezi basin from 1498 when Vasco da Gama first reached the Mozambican coast. Lourenço Marques (explorer), Lourenço Marques explored the area that is now Maputo Bay in 1544. The Portuguese increased efforts for occupying the interior of the colony after the Scramble for Africa, and secured political control over most of its territory in 1918, facing the resistance of Africans during the process. Some territories in Mozambique were handed over in the late 19th cent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wireless Telegraphy
Wireless telegraphy or radiotelegraphy is transmission of text messages by radio waves, analogous to electrical telegraphy using cables. Before about 1910, the term ''wireless telegraphy'' was also used for other experimental technologies for transmitting telegraph signals without wires. In radiotelegraphy, information is transmitted by pulses of radio waves of two different lengths called "dots" and "dashes", which spell out text messages, usually in Morse code. In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves. At the receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code. Radiotelegraphy was the first means of radio communication. The first practical radio transmitters and receivers invented in 1894–1895 by Guglielmo Marconi used radiotelegraphy. It continued to be the only type of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southampton City Council
Southampton City Council is the local authority of the city of Southampton. It is a unitary authority, having the powers of a non-metropolitan county and district council combined. It provides a full range of local government services including council tax billing, libraries, social services, processing planning applications, waste collection and disposal, and it is a local education authority. The council uses a leader and cabinet structure. Labour has been in control of the council since 2022. History Southampton City Council has records in its archives of council meetings as early as 1199. The Local Government Act 1888 established Southampton as a county borough of the county Hampshire, then officially known as the ''County of Southampton''. This meant that the city of Southampton had independent governance from the county. Local government restructuring with an act in 1973 made the City of Southampton a non-metropolitan district within the Hampshire county. It succeeded Ham ...

Code Letters
Code letters or ship's call sign (or callsign) Mtide Taurus - IMO 7626853"> SHIPSPOTTING.COM >> Mtide Taurus - IMO 7626853/ref> were a method of identifying ships before the introduction of modern navigation aids and today also. Later, with the introduction of radio, code letters were also used as radio call signs. History In 1857, the United Kingdom sponsored the ''Commercial Code of Signals for the Use of All Nations at Sea'', which introduced four letter flag signal codes to identify individual ships. The first vessel to be reported in '' Lloyd's List'' by her letters was the ''Mallard'' (LDPN), off Deal, Kent whilst on a voyage from London to Calcutta, India. The Commercial Code of Signals, c. 1900, was modified to become the International Code of Signals. By the 1860s, individual ships were being allocated code letters in the United States and Europe. From 1874, code letters were recorded in Lloyd's Register as part of each individual vessel's entry in the register. Genera ...

Gear Train
A gear train is a mechanical system formed by mounting gears on a frame so the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next. Features of gears and gear trains include: * The gear ratio of the pitch circles of mating gears defines the speed ratio and the mechanical advantage of the gear set. * A planetary gear train provides high gear reduction in a compact package. * It is possible to design gear teeth for gears that are non-circular, yet still transmit torque smoothly. * The speed ratios of chain and belt drives are computed in the same way as gear ratios. See bicycle gearing. The transmission of rotation between contacting toothed wheels can be traced back to the Antikythera mechanism of Greece and the south-pointing chariot of China. Illustrations by the Renaissance scientist Georgius Agricola show gear trains wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the water at t ...

Tonnage
Tonnage is a measure of the cargo-carrying capacity of a ship, and is commonly used to assess fees on commercial shipping. The term derives from the taxation paid on '' tuns'' or casks of wine. In modern maritime usage, "tonnage" specifically refers to a calculation of the volume or cargo volume of a ship. Although tonnage (volume) should not be confused with displacement (the actual weight of the vessel), the long ton (or imperial ton) of 2,240 lb is derived from the fact that a " tun" of wine typically weighed that much. Tonnage measurements Tonnage measurements are governed by an IMO Convention (International Convention on Tonnage Measurement of Ships, 1969 (London-Rules)), which initially applied to all ships built after July 1982, and to older ships from July 1994.

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 ' ...
