Eton Racing Boats (logo)
Eton Racing Boats (commonly referred to as ERB) was a manufacturer of racing boats for rowing, based in Eton, United Kingdom. The company was founded by Eton College, who also funded the construction of the Dorney Lake development. The company ceased trading on Friday 16 February 2007 due to insufficient profits and stiff competition from cheaper good quality rowing equipment. Eric Sims continues to offer equipment supplies via a separate outlet. The former company website claimed that "boats from the Eton workshops have frequently won Henley medals and world championships". The firm also manufactured and sold range of accessories and other products for the sport, including outriggers, megaphones, coaching launches and pontoons, as well as providing maintenance services. Boats Boatbuilding had taken place in the area since the 1800s, with composite racing boats introduced in 1994.

Pontoon (boat)
A pleasure boat with two lengthwise pontoons A pontoon boat is a flattish boat that relies on floats to remain buoyant. These pontoons (also called ''tubes'') contain much reserve buoyancy and allow designers to create large deck plans fitted with a variety of accommodations including expansive lounge areas, stand-up bars, and sun pads. Better tube designs have allowed builders to put ever-increasing amounts of horsepower on the stern. Pontoon boat drafts may be as shallow as eight inches (20 centimetres), which reduces risk of running aground and underwater damage, this allows it to come close to shore to pick up and drop off loads. History A pontoon ferry crossing the Zambezi at Kazungula The 1951 invention of the pontoon motorboat in the United States is credited to a farmer who lived on the Horseshoe chain of lakes, near Richmond, Minnesota. Ambrose Weeres put a wooden platform on two columns of steel barrels welded together end-to-end, creating a sturdy deck that would ...

Single Scull
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 Originally made from wood, shells are now almost always made from a composite material (usually carbon-fibre reinforced plastic) for strength and weight advantages.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 ...

Coxless Pair
A coxless pair is a rowing boat used in the sport of competitive rowing. It is designed for two rowers, who propel the boat with sweep oars. The crew consists of a pair of rowers, each having one oar, one on the stroke side (rower's right hand side) and one on the bow side (rower's lefthand side). As the name suggests, there is no coxswain on such a boat, and the two rowers must co-ordinate steering and the proper timing of oar strokes between themselves or by means of a steering installation which is operated by foot from one of the rowers. The equivalent boat when it is steered by a cox is referred to as a "coxed 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 (usually carbon-fibre reinforced plastic) for strength and weight advantages. Pairs have a fin towards the rear, to help prevent ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coxed Four
A coxed four, also known as a 4+, is a rowing boat used in the sport of competitive rowing. It is designed for four persons who propel the boat with sweep oars and is steered by a coxswain. The crew consists of four rowers, each having one oar, and a cox. There are two rowers on the stroke side (rower's right hand side) and two 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 four". 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 mad ...

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 ...

Composite Materials
A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Typical engineered composite materials include: * Reinforced concrete and masonry *Composite wood such as plywood *Reinforced plastics, such as fibre-reinforced polymer or fiberglass *Ceramic matrix composites ( composite ceramic and metal matrices) *Metal matrix composites *and other advanced composite materials There are various reasons where new material can be favoured. Typical examples include materials which are less expensive, lighter, stronger or more durable when compared with com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maintenance, Repair And Operations
The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure, and supporting utilities in industrial, business, and residential installations. Over time, this has come to include multiple wordings that describe various cost-effective practices to keep equipment operational; these activities occur either before or after a failure. Definitions Maintenance functions can defined as maintenance, repair and overhaul (MRO), and MRO is also used for maintenance, repair and operations. Over time, the terminology of maintenance and MRO has begun to become standardized. The United States Department of Defense uses the following definitions:Federal Standard 1037C and from MIL-STD-188 and from the Department of Defense Dictionary of Military and Associated Terms * Any activity—such as tests, measurements, replacements, adjustments, and repairs—intended to retain or restore a fun ...

Launch (boat)
Launch is a name given to several different types of boat. The wide range of usage of the name extends from utilitarian craft through to pleasure boats built to a very high standard. In naval use, the launch was introduced as a ship's boat towards the end of the 17th century. On each warship, the launch was usually the largest boat out of those carried aboard. It could be propelled by oar or sail, with this type remaining in service into the 20th century. Steam launches were introduced on a trial basis in 1867, but as steam-powered ship's boats became more common, the majority were steam pinnaces. Other military examples were the various motor launches used in the 20th century, employed for harbour defence, anti-submarine patrols, escorting coastal convoys, minesweeping and recovering aircrew from crashed aircraft. Generally, these were decked boats, some of which were capable of fast speeds. A powered boat operated by a regulatory or official organisation may be termed a lau ...

Eton, Berkshire
Eton ( ) is a town in Berkshire, England, on the opposite bank of the River Thames to Windsor, connected to it by Windsor Bridge. The civil parish, which also includes the village of Eton Wick two miles west of the town, had a population of 4,692 at the 2011 Census. Within the boundaries of the historic county of Buckinghamshire, in 1974 it became part of the Berkshire admin area following the Local Government Act 1972; since 1998 it has been part of the unitary authority of Windsor and Maidenhead. The town is best known as the location of Eton College. History The name derives from Old English ''Ēa-tūn'', meaning "River-Town", a reference to Eton's proximity to the River Thames. The land that is now Eton once belonged to the manor of Queen Edith, wife of Edward the Confessor. The land was appropriated by the Normans after 1066; and by 1086, the lord was Walter son of Other. The main road between Windsor and London went through the area and a hamlet sprang up amid pastur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megaphone
A megaphone, speaking-trumpet, bullhorn, blowhorn, or loudhailer is usually a portable or hand-held, cone-shaped acoustic horn used to amplify a person's voice or other sounds and direct it in a given direction. The sound is introduced into the narrow end of the megaphone, by holding it up to the face and speaking into it, and the sound waves radiate out the wide end. A megaphone increases the volume of sound by increasing the acoustic impedance seen by the vocal cords, matching the impedance of the vocal cords to the air, so that more sound power is radiated. It also serves to direct the sound waves in the direction the horn is pointing. It somewhat distorts the sound of the voice because the frequency response of the megaphone is greater at higher sound frequencies. Since the 1960s the voice-powered ''acoustic megaphone'' described above has been replaced by the ''electric megaphone'', which uses a microphone, an electrically-powered amplifier and a folded horn loudsp ...
