SM U-33 (Germany)
SM ''U-33'' was a German Type U 31 U-boat of the Imperial German Navy. Design German Type U 31 submarines were double-hulled ocean-going craft similar to Type 23 and Type 27 boats in dimensions, differing only slightly in propulsion and speed. They were considered very good high sea boats with average manoeuvrability and good surface steering. ''U-33'' had an overall length of , her pressure hull was long. The boat's beam was (o/a), while the pressure hull measured . Type 31s had a draught of with a total height of . The boats displaced a total of ; when surfaced and when submerged. ''U-33'' was fitted with two Germania 6-cylinder two-stroke diesel engines with a total of for use on the surface and two Siemens-Schuckert double-acting electric motors with a total of for underwater use. These engines powered two shafts, each with a propeller, which gave the boat a top surface speed of , and when submerged. Cruising range was at on the surface, and at under water ...

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 Germa ...

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 ' ...

Russian Hospital Ship Portugal
SS ''Portugal'' (russian: госпитальное судно "Португаль") was a steamship originally built by a French shipping company, but requisitioned for use as a Russian hospital ship during the First World War. On she was sunk by a torpedo from the German U-boat . History She was originally built in 1886 for the Brazil and River Plate Line of the Messageries Maritimes Company. She was chartered or purchased by the Russians for use as a hospital ship in the Black Sea. The ship, serviced to take up wounded soldiers along the sea shore Ardeshen, Rize Port, Fakhtia, Tiribon and Of, the ship could have the chance to make only five voyages, beginning on 27 February 1916. Sinking , 1916, ''Portugal'' was towing a string of small flat-bottomed boats to ferry wounded from the shore to the ship. Off Rizeh, on the Turkish coast of the Black Sea, she had stopped as one of the small boats was sinking and repairs were being made. The ship was not carrying wounded at the ...

Hospital Ship
A hospital ship is a ship designated for primary function as a floating medical treatment facility or hospital. Most are operated by the military forces (mostly navies) of various countries, as they are intended to be used in or near war zones. In the 19th century, redundant warships were used as moored hospitals for seamen. The Second Geneva Convention prohibits military attacks on hospital ships that meet specified requirements, though belligerent forces have right of inspection and may take patients, but not staff, as prisoners of war. History Early examples Hospital ships possibly existed in ancient times. The Athenian Navy had a ship named ''Therapia'', and the Roman Navy had a ship named ''Aesculapius'', their names indicating that they may have been hospital ships. The earliest British hospital ship may have been the vessel ''Goodwill'', which accompanied a Royal Navy squadron in the Mediterranean in 1608 and was used to house the sick sent aboard from other ships. ...

Russia
Russia (, , ), or the Russian Federation, is a transcontinental country spanning Eastern Europe and Northern Asia. It is the largest country in the world, with its internationally recognised territory covering , and encompassing one-eighth of Earth's inhabitable landmass. Russia extends across eleven time zones and shares land boundaries with fourteen countries, more than any other country but China. It is the world's ninth-most populous country and Europe's most populous country, with a population of 146 million people. The country's capital and largest city is Moscow, the largest city entirely within Europe. Saint Petersburg is Russia's cultural centre and second-largest city. Other major urban areas include Novosibirsk, Yekaterinburg, Nizhny Novgorod, and Kazan. The East Slavs emerged as a recognisable group in Europe between the 3rd and 8th centuries CE. Kievan Rus' arose as a state in the 9th century, and in 988, it adopted Orthodox Christianity from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Fryatt
Charles Algernon Fryatt (2 December 1872 – 27 July 1916) was a British merchant seaman who was court martialled by the Imperial German Navy for attempting to ram a German U-boat in 1915. When his ship, the , was captured off occupied Belgium in 1916, Captain Fryatt was court-martialled under German military law and sentenced to death for "illegal civilian warfare". International outrage followed his execution by firing squad near Bruges, Belgium. In 1919, his body was reburied with full honours in the United Kingdom. Early life Fryatt was born on 2 December 1872 in Southampton, the son of Charles and Mary Fryatt. He attended Freemantle School in the late 1870s. In 1881, Fryatt's family lived at 22 Trinity Terrace, in St Mary's, Southampton, but later moved to Harwich, Essex where he attended the Corporation School. He and his wife, Ethel, had seven children; six girls and one boy. The children were Olive, Victoria, Doris, Vera, Mabel, Charles and Dorothy. The younger Charles l ...

Great Eastern Railway
The Great Eastern Railway (GER) was a pre-grouping British railway company, whose main line linked London Liverpool Street to Norwich and which had other lines through East Anglia. The company was grouped into the London and North Eastern Railway in 1923. Formed in 1862 after the amalgamation of the Eastern Counties Railway and several other smaller railway companies the GER served Cambridge, Chelmsford, Colchester, Great Yarmouth, Ipswich, King's Lynn, Lowestoft, Norwich, Southend-on-Sea (opened by the GER in 1889), and East Anglian seaside resorts such as Hunstanton (whose prosperity was largely a result of the GER's line being built) and Cromer. It also served a suburban area, including Enfield, Chingford, Loughton and Ilford. This suburban network was, in the early 20th century, the busiest steam-hauled commuter system in the world. The majority of the Great Eastern's locomotives and rolling stock were built at Stratford Works, part of which was on the site of t ...

Stern
The stern is the back or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite the bow, the foremost part of a ship. Originally, the term only referred to the aft port section of the ship, but eventually came to refer to the entire back of a vessel. The stern end of a ship is indicated with a white navigation light at night. Sterns on European and American wooden sailing ships began with two principal forms: the ''square'' or ''transom'' stern and the ''elliptical'', ''fantail'', or ''merchant'' stern, and were developed in that order. The hull sections of a sailing ship located before the stern were composed of a series of U-shaped rib-like frames set in a sloped or "cant" arrangement, with the last frame before the stern being called the ''fashion timber(s)'' or ''fashion piece(s)'', so called for "fashioning" the after part of the ship. This frame is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bow (ship)
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ve ...

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 ...

Motor–generator
A motor–generator (an M–G set) is a device for converting electrical power to another form. Motor–generator sets are used to convert frequency, voltage, or phase of power. They may also be used to isolate electrical loads from the electrical power supply line. Large motor–generators were widely used to convert industrial amounts of power while smaller motor–generators (such as the one shown in the picture) were used to convert battery power to higher DC voltages. While a motor–generator set may consist of distinct motor and generator machines coupled together, a single unit dynamotor (for dynamo–motor) has the motor coils and the generator coils wound around a single rotor; both the motor and generator therefore share the same outer field coils or magnets.Radio Amateur's Handbook 1976, pub. |
