Sinking Of HMS Victoria
The sinking of HMS ''Victoria'' took place at approximately 15:30 on 22 June 1893, after , the flagship of the Royal Navy's Mediterranean Fleet, collided with while on fleet manoeuvres in the Eastern Mediterranean. The collision caused significant damage to ''Victoria''s bow, with a large hole produced causing the ship to rapidly capsizing, capsize. ''Victoria'' took approximately fifteen minutes to sink, with 358 members of the crew, including Vice-admiral (Royal Navy), Vice-Admiral George Tryon, Sir George Tryon, lost in the disaster. Background In 1893, the Royal Navy saw the Mediterranean Sea as a vital sea route between Britain and India under British rule, India, under constant threat from the navies of French Third Republic, France and Kingdom of Italy, Italy. The impressive naval force that the British concentrated to protect these sealanes made Mediterranean Fleet one of the most powerful in the world. On 22 June 1893, the bulk of the fleet, eleven Ironclad warship, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern European Time
Eastern European Time (EET) is one of the names of UTC+02:00 time zone, 2 hours ahead of Coordinated Universal Time. The zone uses daylight saving time, so that it uses UTC+03:00 during the summer. A number of African countries use UTC+02:00 all year long, where it is called Central Africa Time (CAT), although Egypt and Libya also use the term ''Eastern European Time''. The most populous city in the Eastern European Time zone is Cairo, with the most populous EET city in Europe being Athens. Usage The following countries, parts of countries, and territories use Eastern European Time all year round: * Egypt, since 21 April 2015; used EEST ( UTC+02:00; UTC+03:00 with daylight saving time) from 1988–2010 and 16 May–26 September 2014. See also Egypt Standard Time. * Kaliningrad Oblast (Russia), since 26 October 2014; also used EET in years 1945 and 1991–2011. See also Kaliningrad Time. * Libya, since 27 October 2013; switched from Central European Time, which was u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cable Length
A cable length or length of cable is a nautical unit of measure equal to one tenth of a nautical mile or approximately 100 fathoms. Owing to anachronisms and varying techniques of measurement, a cable length can be anywhere from 169 to 220 metres, depending on the standard used. The unit is named after the length of a ship's anchor cable in the Age of Sail. The definition varies: * International: 185.2 m, equivalent to nautical mile * Imperial (Admiralty): 185.32 m, or nautical mile, about 101 fathoms ** The traditional British fathom varied from in the Merchant Navy, making the "historical" cable 169 m to 215.5 m. * US customary (US Navy): 219.5 metres, 120 fathoms (720 feet) See also * Conversion of units Conversion of units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors which change the measured quantity value without changing its effects.

Anchor
An anchor is a device, normally made of metal , used to secure a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ''ancora'', which itself comes from the Greek ἄγκυρα (ankȳra). Anchors can either be temporary or permanent. Permanent anchors are used in the creation of a mooring, and are rarely moved; a specialist service is normally needed to move or maintain them. Vessels carry one or more temporary anchors, which may be of different designs and weights. A sea anchor is a drag device, not in contact with the seabed, used to minimise drift of a vessel relative to the water. A drogue is a drag device used to slow or help steer a vessel running before a storm in a following or overtaking sea, or when crossing a bar in a breaking sea.. Overview Anchors achieve holding power either by "hooking" into the seabed, or mass, or a combination of the two. Permanent moorings use large masses (common ...

Degree (angle)
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane (mathematics), plane angle in which one Turn (geometry), full rotation is 360 degrees. It is not an SI unit—the SI unit of angular measure is the radian—but it is mentioned in the SI Brochure, SI brochure as an Non-SI units mentioned in the SI, accepted unit. Because a full rotation equals 2 radians, one degree is equivalent to radians. History The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year. Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day. Some ancient calendars, such as the Iranian calendar, Persian calendar and the Babylonian calendar, used 360 days for a year. ...

Albert Hastings Markham
Admiral Sir Albert Hastings Markham (11 November 1841 – 28 October 1918) was a British explorer, author, and officer in the Royal Navy. In 1903 he was invested as a Knight Commander of the Order of the Bath. He is also remembered for designing the flag of New Zealand. Family and background Albert Markham was the fifth son of Captain John Markham, who had retired from the navy because of ill health with the rank of lieutenant. John Markham's grandfather, William Markham, had been Archbishop of York. He was a cousin and close friend of Sir Clements Markham.

Rear Admiral
Rear admiral is a senior naval flag officer rank, equivalent to a major general and air vice marshal and above that of a commodore and captain, but below that of a vice admiral. It is regarded as a two star "admiral" rank. It is often regarded as a two-star rank with a NATO code of OF-7. The term originated in the days of naval sailing squadrons and can trace its origins to the Royal Navy. Each naval squadron was assigned an admiral as its head, who commanded from the centre vessel and directed the squadron's activities. The admiral would in turn be assisted by a vice admiral, who commanded the lead ships that bore the brunt of a battle. In the rear of the squadron, a third admiral commanded the remaining ships and, as this section was considered to be in the least danger, the admiral in command of it was typically the most junior. This has continued into the modern age, with rear admiral the most junior admiralty of many navies. In most European navies, the equivalent rank i ...

Horatio Nelson
Vice-Admiral Horatio Nelson, 1st Viscount Nelson, 1st Duke of Bronte (29 September 1758 – 21 October 1805) was a British flag officer in the Royal Navy. His inspirational leadership, grasp of strategy, and unconventional tactics brought about a number of decisive British naval victories during the French Revolutionary and Napoleonic Wars. He is widely regarded as one of the greatest naval commanders in history. Nelson was born into a moderately prosperous Norfolk family and joined the navy through the influence of his uncle, Maurice Suckling, a high-ranking naval officer. Nelson rose rapidly through the ranks and served with leading naval commanders of the period before obtaining his own command at the age of 20, in 1778. He developed a reputation for personal valour and firm grasp of tactics, but suffered periods of illness and unemployment after the end of the American War of Independence. The outbreak of the French Revolutionary Wars allowed Nelson to return to service, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Trafalgar
The Battle of Trafalgar (21 October 1805) was a naval engagement between the British Royal Navy and the combined fleets of the French and Spanish Navies during the War of the Third Coalition (August–December 1805) of the Napoleonic Wars (1803–1815). As part of Napoleon's plans to invade England, the French and Spanish fleets combined to take control of the English Channel and provide the Grande Armée safe passage. The allied fleet, under the command of the French admiral, Pierre-Charles Villeneuve, sailed from the port of Cádiz in the south of Spain on 18 October 1805. They encountered the British fleet under Lord Nelson, recently assembled to meet this threat, in the Atlantic Ocean along the southwest coast of Spain, off Cape Trafalgar. Nelson was outnumbered, with 27 British ships of the line to 33 allied ships including the largest warship in either fleet, the Spanish ''Santísima Trinidad''. To address this imbalance, Nelson sailed his fleet directly at the allied ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signal Lamp
Signal lamp training during World War II A signal lamp (sometimes called an Aldis lamp or a Morse lamp) is a semaphore system using a visual signaling device for optical communication, typically using Morse code. The idea of flashing dots and dashes from a lantern was first put into practice by Captain Philip Howard Colomb, of the Royal Navy, in 1867. Colomb's design used limelight for illumination, and his original code was not the same as Morse code. During World War I, German signalers used optical Morse transmitters called ', with a range of up to 8 km (5 miles) at night, using red filters for undetected communications. Modern signal lamps produce a focused pulse of light, either by opening and closing shutters mounted in front of the lamp, or by tilting a concave mirror. They continue to be used to the present day on naval vessels and for aviation light signals in air traffic control towers, as a backup device in case of a complete failure of an aircraft's radi ...

Flag Semaphore
Flag semaphore (from the Ancient Greek () 'sign' and - (-) '-bearer') is a semaphore system conveying information at a distance by means of visual signals with hand-held flags, rods, disks, paddles, or occasionally bare or gloved hands. Information is encoded by the position of the flags; it is read when the flag is in a fixed position. Semaphores were adopted and widely used (with hand-held flags replacing the mechanical arms of shutter semaphores) in the maritime world in the 19th century. It is still used during underway replenishment at sea and is acceptable for emergency communication in daylight or using lighted wands instead of flags, at night. Contemporary semaphore flag system The current flag semaphore system uses two short poles with square flags, which a signal person holds in different positions to signal letters of the alphabet and numbers. The signaller holds one pole in each hand, and extends each arm in one of eight possible directions. Except for in the re ...
