Bowloader
A bowloader or bow-coxed shell is a racing shell (a type of boat used in rowing) in which the coxswain lies semi-supine in the bow, as opposed to the normal seated position at the stern. Bowloaders are often seen as coxed fours and also coxed pairs. A small number of bowloader eights exist, and one was raced by the Soviet Union in the 1988 Olympics and the 1989 Royal Henley Regatta, as well as the Russian men's crew at the 2002 World Rowing Junior Championships. Steering is difficult because the bow swings less than the stern, so that the coxswain has trouble judging how much the boat has moved laterally, and this problem is exacerbated in an eight. A bowloader is slightly faster than a stern-coxed boat, since the mass of the coxswain in the bow reduces porpoising, and the semi-supine position puts the coxswain's center of mass below the waterline, reducing roll. Both of these factors help to reduce drag. The cox also has better forward vision in a bowloader: in the conven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Loudspeakers
A loudspeaker (commonly referred to as a speaker or speaker driver) is an Acoustical engineering#Electroacoustics, electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or "loudspeaker", comprises one or more such speaker ''drivers'', an enclosure, and electrical connections possibly including a Audio crossover, crossover network. The speaker driver can be viewed as a linear motor attached to a Diaphragm (acoustics), diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal. This is thus the opposite function to the microphone; indeed the ''dynamic speaker'' driver, by far the most common type, is a linear mot ...

Amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It may increase the power significantly, or its main effect may be to boost the voltage or current (power, voltage or current amplifier). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a greater amplitude signal at its output. The ratio of output to input voltage, current, or power is termed gain (voltage, current, or power gain). An amplifier, by definition has gain greater than unity (if the gain is less than unity, the device is an attenuator). An amplifier can either be a separate piece of equipment or an electrical circuit contained within another device. Amplification is fundamental to modern electronics, and amplifiers are widely used in almost all electronic equipment. Amplifiers can be categorize ...

World Rowing Junior Championships
The World Rowing Junior Championships is an international rowing regatta organized by FISA (the International Rowing Federation). A rower or coxswain shall be classified as a Junior until 31 December of the year in which he reaches the age of 18. After that date, he shall be classified as an Under 23 rower. During Olympic years it is held at the same location as the Senior World Rowing Championships. The first FISA Youth Regatta was held in 1967 and has been held every year since then, being raised to the status of FISA Junior Champs in 1970 and Junior World Champs in 1985. Many European countries send athletes not up to the standard for World Championships to the Coupe de la Jeunesse.

Royal Henley Regatta
Henley Royal Regatta (or Henley Regatta, its original name pre-dating Royal patronage) is a rowing event held annually on the River Thames by the town of Henley-on-Thames, England. It was established on 26 March 1839. It differs from the three other regattas rowed over approximately the same course, Henley Women's Regatta, Henley Masters Regatta, and Henley Town and Visitors' Regatta, each of which is an entirely separate event. The regatta lasts for six days (Tuesday to Sunday) ending on the first weekend in July. Races are head-to-head knock out competitions, raced over a course of . The regatta regularly attracts international crews to race. The most prestigious event at the regatta is the Grand Challenge Cup for Men's Eights, which has been awarded since the regatta was first staged. As the regatta pre-dates any national or international rowing organisation, it has its own rules and organisation, although it is recognised by both British Rowing (the governing body of rowin ...

Rowing At The 1988 Summer Olympics – Men's Eight
The men's eight competition at the 1988 Summer Olympics took place at Misari Regatta, South Korea. It was held from 20 to 25 September. There were 10 boats (90 competitors) from 10 nations, with each nation limited to a single boat in the event. The event was won by West Germany, the nation's first victory (and first medal) in the men's eight since 1968. It was West Germany's second gold medal in the event, tying Great Britain and East Germany for second-most, behind the United States with 11. In a photo finish for second place, the Soviet Union took silver over the United States. Background This was the 20th appearance of the event. Rowing had been on the programme in 1896 but was cancelled due to bad weather. The men's eight has been held every time that rowing has been contested, beginning in 1900. The United States had dominated the men's eight for four decades from the 1920s through the 1950s, but had not taken Olympic gold since 1964. A victory in the 1987 World Rowing ...

Eight (rowing)
An eight is a rowing boat used in the sport of competitive rowing (crew). It is designed for eight rowers, who propel the boat with sweep oars, and is steered by a coxswain, or "cox". Each of the eight rowers has one oar. The rowers, who sit in a line in the centre of the boat and facing the stern, are usually placed alternately, with four on the port side (rower's right hand side - also traditionally known as "stroke side") and four on the starboard side (rower's lefthand side - known as "bow side"). The cox steers the boat using a rudder and is normally seated at the stern of the boat. Because of the speed of the boat, it is generally considered unsafe to row coxless or to have a bowloader cox. Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to reduce drag to a minimum. Originally made from wood, shells are now almost always made from a composite material (usually carbon-fibre reinforced plastic) for strength and w ...

Racing Shell
In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ''shell'') is an extremely narrow, and often comparatively long, rowing boat specifically designed for racing or exercise. It is outfitted with long oars, outriggers to hold the oarlocks away from the boat, and sliding seats. The boat's long length and semicircular cross-section reduce drag to a minimum. This makes the boat both fast and unstable. It must be balanced by the rowers to avoid tipping. Being able to balance – or "set" – the boat while putting maximum effort into the oars is therefore an essential skill of sport rowing. History The racing shell evolved from the simple working rowboat. Boats with longer hulls and narrower in beam were developed in the early 19th century specifically for team racing. These dedicated boats were the first boats that could be called racing shells, and they evolved into the highly specialized forms used today. Riggers A narrower boat provides a sharper ...

Coxed Pair
A coxed pair is a rowing boat used in the sport of competitive rowing. It is designed for two persons who propel the boat with sweep oars and is steered by a coxswain. The crew consists of two rowers, each having one oar, and a cox. One rower is on the stroke side (rower's right hand side) and other is on the bow side (rower's lefthand side). The cox steers the boat using a rudder and may be seated at the stern of the boat where there is a view of the crew or in the bow (known as a bowloader). With a bowloader, amplification is needed to communicate with the crew which is sitting behind, but the cox has a better view of the course and the weight distribution may help the boat go faster. When there is no cox, the boat is referred to as a "coxless pair". Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to reduce drag to a minimum. Originally made from wood, shells are now almost always made from a composite material ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
