Blaze (dinghy)
The Blaze was designed in the mid-1990s by Ian Howlett, one time International 14 designer and associated with Americas Cup design work and John Caig, winner of Fireball Worlds. It is a powerful winged single-hander with well-developed 10 m sail. Unusually in recent performance designs both foils are pivoting enabling the centreboard to be adjusted from the wing as well making it particularly suitable for estuaries and shallow lakes. Development The Blaze was originally built by Ian Howlett and John Caig, and marketed by Topper International from 1996. At the outset the Blaze incorporated equalisation with lighter weight helms being allowed wider rack widths but carrying compensating lead weights. After a few years the class membership voted to abandon equalisation. In 2000 an active class association ran a sail development program to produce a more responsive sail, dropping some of the excessive leech Leeches are segmented parasitic or predatory worms that comprise ...

International 14
The International 14 is a British racing sailboat, crewed by two sailors. The class was established in 1928. The boat is a developmental sailing class and so the design rules and the boats themselves have changed dramatically over time to keep the International 14 at the leading edge of sailing technology. Many designers have contributed to the boat. Sailboatdata.com noted "the International 14 is a high performance 2-Man, development racing dinghy with a long history of performance developments that often been adopted in the design of later boats. Today, with hiking racks, a giant flat head main, and its 'skiff' like hull, an up-to-date racing model bears little resemblance to the earlier boats." The design became an international World Sailing class in 1928. Production The design has been built by many builders over a century of construction. Today it is built by Ovington Boats and Composite Craft in the United Kingdom. From 1946 to 1970 it was built in the United States b ...

Americas Cup
The America's Cup, informally known as the Auld Mug, is a trophy awarded in the sailing (sport), sport of sailing. It is the oldest International sport, international competition still operating in any sport. America's Cup match racing, match races are held between two sailing yachts: one from the yacht club that currently holds the trophy (known as the defender) and the other from the yacht club that is challenging for the cup (the challenger). Matches are held several years apart on dates agreed between the defender and the challenger. There is no fixed schedule, but the races have generally been held every three to four years. The most recent America's Cup match took place in March 2021. The cup was originally known as the 'R.Y.S. £100 Cup', 1851 America's Cup, awarded in 1851 by the British Royal Yacht Squadron for a race around the Isle of Wight in the United Kingdom. The winning yacht was a schooner called ''America (yacht), America'', owned by a syndicate of members fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sail
A sail is a tensile structure—which is made from fabric or other membrane materials—that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or bonded filaments—usually in a three- or four-sided shape. A sail provides propulsive force via a combination of lift and drag, depending on its angle of attack—its angle with respect to the apparent wind. Apparent wind is the air velocity experienced on the moving craft and is the combined effect of the true wind velocity with the velocity of the sailing craft. Angle of attack is often constrained by the sailing craft's orientation to the wind or point of sail. On points of sail where it is possible to align the leading edge of the sail with the apparent wind, the sail may act as an airfoil, generating propulsive force as air p ...

Centreboard
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] |

Parts Of A Sail
Sail components include the features that define a sail's shape and function, plus its constituent parts from which it is manufactured. A sail may be classified in a variety of ways, including by its orientation to the vessel (e.g. ''fore-and-aft'') and its shape, (e.g. ''(a)symmetrical'', ''triangular'', ''quadrilateral'', etc.). Sails are typically constructed out of flexible material that is shaped by various means, while in use, to offer an appropriate airfoil, according to the strength and apparent direction of the wind. A variety of features and fittings allow the sail to be attached to lines and spars. Whereas conventional sails form an airfoil with one layer of fabric, wingsails comprise a structure that has material on both sides to form an airfoil—much like a wing placed vertically on the vessel—and are beyond the scope of this article. Classifications Sails may be classified as either ''triangular'', which describes sails that either come to one point of suspen ...

Rondar
Oxazepam is a short-to-intermediate-acting benzodiazepine. Oxazepam is used for the treatment of anxiety and insomnia and in the control of symptoms of alcohol withdrawal syndrome. It is a metabolite of diazepam, prazepam, and temazepam, and has moderate amnesic, anxiolytic, anticonvulsant, hypnotic, sedative, and skeletal muscle relaxant properties compared to other benzodiazepines. It was patented in 1962 and approved for medical use in 1964. Medical uses It is an intermediate-acting benzodiazepine with a slow onset of action, so it is usually prescribed to individuals who have trouble staying asleep, rather than falling asleep. It is commonly prescribed for anxiety disorders with associated tension, irritability, and agitation. It is also prescribed for drug and alcohol withdrawal, and for anxiety associated with depression. Physicians may use oxazepam outside its approved indications to treat social phobia, post-traumatic stress disorder, insomnia, premenstrual syndrome, a ...

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] |
