Single Sculls
A single scull (or a scull) is a rowing boat designed for a single person who propels the boat with two oars, one in each hand. Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to minimize drag. They have riggers, which apply the forces symmetrically to each side of the boat and (usually) a fin towards the rear which helps prevent roll and yaw. Originally made from wood, shells are now almost always made from a composite material (usually carbon-fibre reinforced plastic) for strength and weight advantages. Recreational single sculls tend to be shorter and a little wider than racing boats and can have a slightly flattened hull shape to provide more stability. Recreational single sculls can be made of a variety of materials including carbon fiber, fiberglass, wood or rotomoulded polyethylene. The single scull is the 2nd slowest category of racing boat (faster than the coxed pair), and competitors are recognised by other ro ...

Max Schmitt In A Single Scull
''Max Schmitt in a Single Scull'' (also known as ''The Champion Single Sculls'' or ''The Champion, Single Sculls'') is an 1871 painting by Thomas Eakins, Goodrich catalogue #44. It is in the permanent collection of the Metropolitan Museum of Art. Set on the Schuylkill River in Philadelphia, Pennsylvania, it celebrates Eakins's friend Max Schmitt's victory in the October 5, 1870, single sculls competition. The sculler Max Schmitt (1843–1900) had attended Philadelphia Central High School with Eakins, and the two were close friends. Schmitt was a member of the Pennsylvania Barge Club – as, it is presumed, was Eakins – one of nine men's clubs in the Schuylkill Navy, and twelve that rowed on the river. The Schuylkill Navy had been organized in 1858, with approximately 300 members, and began hosting annual regattas in 1859 (with a four-year hiatus for the American Civil War). Initially, the races were for 6-oared and 4-oared gigs and barges, but a new kind of lightweigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thames Skiff
A Thames skiff is a traditional River Thames wooden rowing boat used for the activity of skiffing. These boats evolved from Thames wherries in the Victorian era to meet a passion for river exploration and leisure outings on the water. Construction The Thames skiff owes its origins to the clinker boat building technique, of over-lapping timber planking, that's known to have existed in the region from before the 6th century Anglo-Saxon Snape and Sutton Hoo ship burials. Many of the terms used for parts of the skiff are of Germanic origin – " tholes", "thwarts", and " sax". Planks on either side of a wooden keel are laid down following the outline of a sham (temporary pattern) placed across the keel. The planks are nailed in place and then a transverse strengthening framework of ribs is added. Oars (or blades) are held in place by wooden thole pins at the side of the boat rather than rowlocks or outriggers. The thole pins are designed to give way if too much pressure is put o ...

Double Scull
A double scull is a rowing boat used in the sport of competitive rowing. It is designed for two persons who propel the boat by sculling with two oars each, one in each hand. Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to reduce drag to a minimum. They usually have a fin towards the rear, to help prevent roll and yaw. Originally made from wood, shells are now almost always made from a composite material (usually carbon-fibre reinforced plastic) for strength and weight advantages. The riggers in sculling apply the forces symmetrically to each side of the boat. Double sculls is one of the classes recognized by the International Rowing Federation and the Olympics. In contrast to the combination of the coxed pair, in which the distribution of the riggers means the forces are staggered alternately along the boat, the symmetrical forces in sculling make the boat more efficient and so the double scull is faster than the ...

World Rowing Championships
The World Rowing Championships is an international rowing regatta organized by FISA (the International Rowing Federation). It is a week-long event held at the end of the northern hemisphere summer and in non-Olympic years is the highlight of the international rowing calendar. History The first event was held in Lucerne, Switzerland, in 1962. The event then was held every four years until 1974, when it became an annual competition. Also in 1974, Men's lightweight and Women's open weight events were added to the championships. Initially, Men's events were 2000 metres long and Women's events 1000 metres. At the 1984 World Championships in Montreal, Canada, Women's lightweight demonstration events were raced over a 2000-metre course for the first time. In 1985, Women's lightweight events were officially added to the schedule and all Men's and Women's events were contested over a 2000-metre course. Since 1996, during (Summer) Olympic years, the World Rowing Junior Championships are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rowing At The Summer Olympics
Rowing at the Summer Olympics has been part of the competition since its debut in the 1900 Summer Olympics. Rowing was on the program at the 1896 Summer Olympics but was cancelled due to bad weather. Only men were allowed to compete until the women's events were introduced at the 1976 Summer Olympics in Montreal which gave national federations the incentive to support women's events and catalysed growth in women's rowing. Lightweight rowing events (which have weight-limited crews) were introduced to the games in 1996. Qualifying for the rowing events is under the jurisdiction of the World Rowing Federation. World Rowing predates the modern Olympics and was the first international sport federation to join the modern Olympic movement. Summary Events At the 2016 and other recent Olympics, the following 14 events were contested: *Men: Single sculls, Double sculls, Quadruple sculls, Coxless pair, Coxless four, Eight. *Lightweight Men: Double sculls, Coxless four *Women: Sing ...

Henley Royal 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 rowi ...

World Sculling Championship
The World Sculling Championship (1863–1957), evolved from the Championship of the Thames for professional scullers. Only the sport of boxing claims an older Championship of the World. It is notable that Jack Broughton, the "Father of Boxing", trained scullers for prize contests which had their roots in wager races which had taken place from the middle of the 18th century on the Thames. History The first race for the Professional Championship of the Thames took place between Westminster and Hammersmith, on the River Thames in London in September 1831, when John Williams of Waterloo Bridge challenged Charles Campbell of Westminster for the Sculling Championship of the Thames. This was just over a year after the first Wingfield Sculls race for the Amateur Championship of the Thames had been held. The race was initially dominated by oarsmen from the Thames, but a fierce rivalry soon arose between Newcastle and London after the famous Tyne sculler, Robert Chambers became the first ...

Wingfield Sculls
The Wingfield Sculls is a rowing race held annually on the River Thames in London, England, on the Championship Course from Putney to Mortlake. The race is between single scullers and is usually on the Saturday three to four weeks before the Scullers Head of the River Race which is the same race in reverse, attracts more international entries and is held in November every year. Due to tide changes on the Tideway, the race may therefore be in October or in November. History The race was founded on 10 August 1830, at the instigation of barrister Henry Colsell Wingfield. The idea for the race was suggested at a dinner after a sculling race and following this a subscription dinner was held at the Swan in Battersea, where money was raised to fund the event, the rules were decided and a date was set. The initial conditions were that the race should be run on the half tide from Westminster to Putney against all challengers, annually on 10 August forever (10 August being Wingfield's ...

Skiffing
Skiffing refers to the sporting and leisure activity of rowing (or more correctly sculling Sculling is the use of oars to propel a boat by moving them through the water on both sides of the craft, or moving one oar over the stern. A long, narrow boat with sliding seats, rigged with two oars per rower may be referred to as a scull, it ...) a Thames skiff. The skiff is a traditional hand built clinker-built wooden craft of a design which has been seen on the River Thames and other waterways in England and other countries since the 19th century. Sculling is the act of propelling the boat with a pair of oars (or blades), as opposed to rowing which requires both hands on a single oar. Skiffs Thames skiffs were developed in the 19th century primarily for leisure use by private individuals sculling themselves. The design was based on the Thames Wherry, wherries and Pleasure barge, shallops that were operated by watermen as a water taxi service in London. By the late 19th century, wh ...

Feedback
Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to ''feed back'' into itself. The notion of cause-and-effect has to be handled carefully when applied to feedback systems: History Self-regulating mechanisms have existed since antiquity, and the idea of feedback had started to enter economic theory in Britain by the 18th century, but it was not at that time recognized as a universal abstraction and so did not have a name. The first ever known artificial feedback device was a float valve, for maintaining water at a constant level, invented in 270 BC in Alexandria, Egypt. This device illustrated the principle of feedback: a low water level opens the valve, the rising water then provides feedback into the system, closing the valve when the required level is reached. This then reoccurs in a circular fashion as the water level fluctuates. Centrifugal governors were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
