National E
The National E (formerly Lazy E) is a two-person intermediate to senior sailing dinghy complete with main, jib, spinnaker and trapeze. It was designed by Jack Holt in 1962 as a fast stable boat. It encapsulates experience gained from his earlier designs of the GP14 and the Enterprise Enterprise (or the archaic spelling Enterprize) may refer to: Business and economics Brands and enterprises * Enterprise GP Holdings, an energy holding company * Enterprise plc, a UK civil engineering and maintenance company * Enterprise .... It has a strong following in Australia with national titles held annually and over 560 sail numbers issued to date.

Monohull
right A monohull is a type of boat having only one hull, unlike multihulled boats which can have two or more individual hulls connected to one another. Fundamental concept Among the earliest hulls were simple logs, but these were generally unstable and tended to roll over easily. Hollowing out the logs into a dugout canoe doesn't help much unless the hollow section penetrates below the log's center of buoyancy, then a load carried low in the cavity actually stabilizes the craft. Adding weight or ballast to the bottom of the hull or as low as possible within the hull adds stability. Naval architects place the center of gravity substantially below the center of buoyancy; in most cases this can only be achieved by adding weight or ballast. The use of stones and other weights as ballast can be traced back to the Romans, Phoenicians and Vikings. Modern ships carry tons of ballast in order to maintain their stability; even heavily laden cargo ships use ballast to optimize the distr ...

Glass-reinforced Plastic
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GFK ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plywood
Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF), oriented strand board (OSB) and particle board (chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called ''cross-graining'' and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composit ...

Bermuda Rig
A Bermuda rig, Bermudian rig, or Marconi rig is a configuration of mast and rigging for a type of sailboat and is the typical configuration for most modern sailboats. This configuration was developed in Bermuda in the 1600s; the term ''Marconi'', a reference to the inventor of the radio, Guglielmo Marconi, became associated with this configuration in the early 1900s because the wires that stabilize the mast of a Bermuda rig reminded observers of the wires on early radio masts. Description The rig consists of a triangular sail set aft of the mast with its mainsail raised to the top of the mast; its luff runs down the mast and is normally attached to it for its entire length; its tack is attached at the base of the mast; its foot (in modern versions of the rig) controlled by a boom; and its clew attached to the aft end of the boom, which is controlled by its sheet.''Boats, Boffins and Bowlines: The Stories of Sailing Inventors and Innovations'', by George Drower.

Centerboard
A centreboard or centerboard (US) is a retractable hull appendage which pivots out of a slot in the hull of a sailboat, known as a ''centreboard trunk'' (UK) or ''centerboard case'' (US). The retractability allows the centreboard to be raised to operate in shallow waters, to move the centre of lateral resistance (offsetting changes to the sailplan that move the centre of effort aft), to reduce drag when the full area of the centreboard is not needed, or when removing the boat from the water, as when trailering. A centreboard which consists of solely a pivoting metal plate is called a centerplate. A daggerboard is similar but slides vertically rather than pivoting. The analog in a scow is a bilgeboard: these are fitted in pairs and used one at a time. General History Lt. John Schank (c. 1740 – 6 February 1823) was an officer of the British Royal Navy and is credited with the invention of the centerboard. Schank, however, gave credit for the idea to British Brigadier General ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jack Holt (dinghy Designer)
Jack Holt, OBE (8 April 1912 – 14 November 1995) was a prolific designer of sailing dinghies. His pioneering designs of dinghies using plywood did much to popularise the sport of sailing in the period immediately following World War II. Born in Hammersmith, London near the River Thames Holt designed more than 40 boats, many of which are listed below. He worked for many years with fellow sailing enthusiast and businessman Beecher Moore. Jack Holt was awarded an OBE in 1979 for his services to sailing. Sailing Clubs Jack Holt has been associated with several sailing clubs. His premises were next door to Ranelagh Sailing Club, and he designed the Merlin Rocket and his National 12 designs there. In 1956 he was a co-founder of Wraysbury Lake Sailing Club. He was closely associated with the London Corinthian Sailing Club, very close to his Putney premises.

GP14
The GP14 is a popular sailing dinghy, with well over 14,000 built. The class is active in the UK, Ireland, Australia, South Africa, Sri Lanka and parts of north-eastern USA, and the GP 14 can be used for both racing and cruising. Design The GP14 was designed by Jack Holt in 1949, with the assistance of the Dovey Yacht Club in Aberdyfi. The idea behind the design was to build a General Purpose (GP) 14-foot dinghy which could be sailed or rowed, capable of also being powered effectively by a small outboard motor, able to be towed behind a small family car and able to be launched and recovered reasonably easily, and stable enough to be able to lie to moorings or anchor when required. Racing soon followed, initially with some degree of opposition from Yachting World, who had commissioned the design, and the boat soon turned out to be an outstanding racing design also. The boat was initially designed with a main and small jib as a comfortable family dinghy. In a desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enterprise (dinghy)
The Enterprise is a Bermuda rigged dinghy sailing, sailing dinghy with a Chine (boating), double-chined hull and distinctive blue sails. Normally crewed by two, and sometimes carrying a third crew member, it may also be sailed single-handed. History The Enterprise was designed by Jack Holt (dinghy designer), Jack Holt in 1956 for News Chronicle, The News Chronicle during the post-war sailing boom, becoming the first UK sailing dinghy to be sponsored by a national newspaper (followed in due course by the Mirror Dinghy, also designed by Jack Holt). It remains popular in the United Kingdom and a dozen or so other countries, for Cruising (maritime), cruising and Dinghy racing, racing. Adopted by many sailing schools, the Enterprise's combination of size, weight, and power has widespread appeal. The Enterprise is accredited as an International Class by the International Sailing Federation, the ISAF. The Enterprise is most often sailed with no spinnaker. However the international cl ...

Dinghies
A dinghy is a type of small boat, often carried or towed by a larger vessel for use as a tender. Utility dinghies are usually rowboats or have an outboard motor. Some are rigged for sailing but they differ from sailing dinghies, which are designed first and foremost for sailing. A dinghy's main use is for transfers from larger boats, especially when the larger boat cannot dock at a suitably-sized port or marina. The term "dinghy towing" sometimes is used to refer to the practice of towing a car or other smaller vehicle behind a motorhome, by analogy to towing a dinghy behind a yacht. Etymology The term is a loanword from the Bengali ', Urdu ', and Hindi '. Types Dinghies usually range in length from about . Larger auxiliary vessels are generally called tenders, pinnaces or lifeboats. Folding and take-down multi-piece (nesting) dinghies are used where space is limited. Some newer dinghies have much greater buoyancy, giving them more carrying capacity than older b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sailing In Australia
Sailing is a popular sport and recreational activity in Australia with its varied coastline and often warm climate. Australian Sailing is the peak body in charge of sailing as recognised by the International Sailing Federation In 2017-18 there were over 80,000 registered sailors and over 16,000 events held across the country. Clubs Sailing Clubs are common in Australia. Large cities have significant numbers of clubs catering to boats from off the beach dinghys to serious ocean racing. Sydney for example, has over 40 sailing clubs. Most moderate sized towns with sailable water nearby have a sailing club. Many clubs hold weekly races, annual championships and annual races. Sailing Associations Australia has a large number associations ranging from one design class associations, which sail boats bound by strict rules to open associations for development and broad communities of boats. Associations are generally at a national level with state based subsidiaries, although some ass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
