Flying Dutchman (dinghy)
The Flying Dutchman is a Dutch Planing (boat), planing sailing dinghy that was designed by Uus Van Essen and Conrad Gülcher as a high performance, one design Sailing (sport), racer and first built in 1951. The boat was an Olympic sailing classes, Olympic sailing class from 1960 until 1992. Production The boat was built in the past by Sunbeam Yachts, Alpa Yachts, Mader Bootswerft, MacKay Boats, Plastrend/Composite Technologies, Lanaverre, Lockley Newport Boats, Advance Sailboat Corp., Binks Yacht Constructions, Chantier Naval Costantini and Mobjack Manufacturing, starting in 1951. More than 10,000 have been built. In 2022 Mader Bootswerft were still producing the design. Design The Flying Dutchman is a racing sailboat, initially built of wood, with many modern boats made from fiberglass sandwich construction with a plastic deck. Cold-molded plywood is still used and some sailers prefer that material. The boat has a Fractional rig, fractional sloop rig, a spooned raked stem, ...

Uus Van Essen
Tennessine is a synthetic element; it has Chemical symbol, symbol Ts and atomic number 117. It has the second-highest atomic number and joint-highest atomic mass of all known elements and is the penultimate element of the Period 7 element, 7th period of the periodic table. It is named after the U.S. state of Tennessee, where key research institutions involved in its discovery are located (however, the IUPAC says that the element is named after the "region of Tennessee"). The discovery of tennessine was officially announced in Dubna, Russia, by a Russian–American collaboration in April 2010, which makes it the most recently discovered element. One of its Decay product, daughter isotopes was created directly in 2011, partially confirming the experiment's results. The experiment was successfully repeated by the same collaboration in 2012 and by a joint German–American team in May 2014. In December 2015, the IUPAC/IUPAP Joint Working Party, Joint Working Party of the Internatio ...

Fiberglass
Fiberglass (American English) or fibreglass (English in the Commonwealth of Nations, Commonwealth English) is a common type of fibre-reinforced plastic, 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 (composite), 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-reinforced polymers, 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 ...

Raked Stem
The stem is the most forward part of a boat or ship's bow and is an extension of the keel itself. It is often found on wooden boats or ships, but not exclusively. Description The stem is the curved edge stretching from the keel below, up to the gunwale of the boat. It is part of the physical structure of a wooden boat or ship that gives it strength at the critical section of the structure, bringing together the port and starboard side planks of the hull. Plumb and raked stem There are two styles of stems: ''plumb'' and ''raked''. When the stem comes up from the water, if it is perpendicular to the waterline it is "plumb". If it is inclined at an angle to the waterline it is "raked". (For example, "The hull is single decked and characterized by a plumb stem, full bows, straight keel, moderate deadrise, and an easy turn of bilge.") Stemhead Because the stem is very sturdy, the top end of it may have something attached, either ornamental or functional in nature. On small ...

Fractional Rig
A fractional rig on a sailing vessel consists of a foresail, such as a jib or genoa sail, that does not reach all the way to the top of the mast. The forestay is a wire that secures the mast to the front of the boat. With a fractional rig, the forestay is attached between about 1/8 and 1/4 of the length of the mast lower down, rather than being attached to the top of the mast as in a masthead rig. The foresail (jib or genoa) is then rigged to this stay. The mast is farther forward on the boat than on a masthead rig and so it has a larger mainsail. Masthead rigs are most common on larger keelboats or cruisers. A fractional rig is typically used on sailing dinghies and racing oriented keelboats, such as the J/24. Fractional rigs were introduced on race boats in order to allow more controllability of the surface of the mainsail and also less drag when sailing upwind. According to one manufacturer, "a key to making fast boats easier to sail than slow boats is the 'fraction ...

Plywood
Plywood is a composite material manufactured from thin layers, or "plies", of wood veneer that have been stacked and glued together. It is an engineered wood from the family of manufactured boards, which include plywood, medium-density fibreboard (MDF), oriented strand board (OSB), and particle board (or chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. The sheets of wood are stacked such that each layer has its grain set typically (see below) perpendicular to its adjacent layers. 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 thickness swelling 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, that is, the surface layers ha ...

Sailboat
A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture. Types Although sailboat terminology has varied across history, many terms have specific meanings in the context of modern yachting. A great number of sailboat-types may be distinguished by size, hull configuration, keel type, purpose, number and configuration of masts, and sail plan. Popular monohull designs include: Cutter The cutter is similar to a sloop with a single mast and mainsail, but generally carries the mast further aft to allow for two foresails, a jib and staysail, to be attached to the head stay and inner forestay, respectively. Once a common racing configuration, today it gives versatility to cruising boats, especially in allowing a small staysail to be flown from the inner stay in high winds. Catboat A catboat has a single mast mounted far forw ...

2008 Cannonball Regatta - Flying Dutchman
8 (eight) is the natural number following 7 and preceding 9. Etymology English ''eight'', from Old English '', æhta'', Proto-Germanic ''*ahto'' is a direct continuation of Proto-Indo-European '' *oḱtṓ(w)-'', and as such cognate with Greek and Latin , both of which stems are reflected by the English prefix oct(o)-, as in the ordinal adjective ''octaval'' or ''octavary'', the distributive adjective is ''octonary''. The adjective ''octuple'' (Latin ) may also be used as a noun, meaning "a set of eight items"; the diminutive '' octuplet'' is mostly used to refer to eight siblings delivered in one birth. The Semitic numeral is based on a root ''*θmn-'', whence Akkadian ''smn-'', Arabic ''ṯmn-'', Hebrew ''šmn-'' etc. The Chinese numeral, written (Mandarin: ''bā''; Cantonese: ''baat''), is from Old Chinese ''*priāt-'', ultimately from Sino-Tibetan ''b-r-gyat'' or ''b-g-ryat'' which also yielded Tibetan '' brgyat''. It has been argued that, as the cardinal nu ...

Olympic Sailing Classes
The Olympic sailing classes have been used in the sport of Sailing/Yachting during the Olympic Summer Games since 1896. Since then, 46 different classes have been used. History Over a period of more than 112 years, in a sport that uses complex technical equipment, classes will be discontinued for use at the Olympics. Reasons for discontinuation of a class varied from economical, logistical and technological to emotional and even political. Some of the discontinued classes remain very strong International - or National classes. Others filled a niche in a specific area like sailing schools or local club racing. Some faded away. The "Former Olympic Sailing Classes", together with their crews form an important and significant part of the history of sailing in general and Olympic Sailing in particular. These tables give an overview of the classes and when they were used for Olympic sailing. Current Olympic Classes Discontinued Olympic Classes Pre-WWII games (1900–1936) Post-W ...

One Design
One-design racing is a racing method which may be adopted in sports using complex equipment, whereby all vehicles have identical or very similar designs or models, avoiding the need for a handicap system. Motorsport One-make racing series (also known as spec racing series) are racing series in which all competitors race with identical or very similar vehicles from the same manufacturer and suppliers. Typically, this means the same type of chassis, powertrain, tyres, brakes, and fuel are used by all drivers. The idea behind one-make car racing is that success will be based more on driver skill and car setup, instead of engineering skill and budget. One-make series are popular at an amateur level as they are affordable, due to the use of a common engine and chassis. Examples of one-make racing series from around the world included the Dodge Viper Challenge, Ferrari Challenge, Porsche Carrera Cup and Supercup, Radical European Masters, Mini Challenge and Commodore Cup.

Planing (boat)
Planing ( ) is the mode of operation for a waterborne craft in which its weight is predominantly supported by hydrodynamic lift, rather than hydrostatic lift (buoyancy). Many forms of marine transport make use of planing, including fast ferries, racing boats, seaplanes, and water skis. Most surfboards are planing or semi-planing hulls. Beyond planing, fast vessel designs have seen a transition to hydrofoil designs. History The earliest documented planing sailboat was a proa built in 1898 by Commodore Ralph Munroe. It was capable of speeds of more than twice the hull speed. Planing a sailing dinghy was first popularised by Uffa Fox in Britain. In 1928 Fox introduced planing to the racing world in his International 14 dinghy, ''Avenger''. That year he gained 52 first places, 2 seconds, and 3 third places out of 57 race starts. This performance was noticed by other designers who further developed them. Over the years, many dinghies have acquired the ability to plane. Mat ...
