Nacra Infusion
The Nacra F18 Infusion was announced in 2006 and launched in January 2007 as a One Design catamaran conforming to the Formula 18 class rules. It quickly developed into a class in its own right. The principle designer was Morrelli & Melvin but also included significant input from Peter Vink (Performance Sails) and Gunnar Larsen (Nacra). The design takes its name from the vacuum infusion process used in its hull construction. The Nacra F18 Infusion has been a recognized World Sailing as an international competition class since November 2010. The Nacra F18 Infusion design was later developed into the F18 Evolution and the NACRA F20 Carbon. Design The Nacra F18 Infusion is a racing sailboat, built in accordance with the Formula 18 Class Rules and its own One Design construction manual. These rules dictate it is a fractional sloop rig with aluminum spars. The boat is a sandwich construction with fibreglass skins made using vinylester resin over a foam core. The Mk3 version us ...

One-design Racing
One-design racing is a racing method which may be adopted in sports which use complex equipment, whereby all vehicles have identical or very similar designs or models, avoiding the need for a Handicapping, handicap system. Sailing There are two primary methods of competition in sailboat racing: One-design and Handicap (sailing), handicap racing (e.g. Portsmouth Yardstick, PHRF, Performance Handicap Racing Fleet and LYS (sailing), Leading Yard Stick). One design refers to a racing class that consists of just one model or design of sailboat. In one-design racing, the first boat to finish wins the race. This is contrasted with handicap racing, where time is added or subtracted from the finishing times based on design factors and mathematical formulas to determine the winner. In between One-design and handicap racing, a number of other approaches exist. One-design classes can be contrasted with a Sailing (sport)#Development Classes, development class, the classic example being the Am ...

Coen De Koning (sailing)
Coen de Koning (30 March 1879 – 29 July 1954) was a speed skater and cyclist. He started his sports career as a cyclist, but switched to speed skating and became the second Dutch speed skater to win a world title, in 1905. He finished second in 500 m, and won the 1500, 5000 and 10,000 m events. De Koning won the national all-around title in 1903, 1905 and 1912, and set national records in the 500 m and 10,000 m in 1905; these records stood until 1926 and 1929. De Koning also set a world record in one-hour skating, at 32,370 m in 1906, and won the Elfstedentocht in 1912 and 1917. Family De Koning came from a speed skating family. His brother Jacobus "Sjaak" Petrus de Koning won the national all-around title in 1914. His son Jacobus Petrus Coenradus de Koning (born 1907) competed at the 1942 national championships, and his cousin Aad de Koning took part in the 1948 Winter Olympics The 1948 Winter Olympics, officially known as the V Olympic Winter Games (german: V.

Formula 18 World Championships
In science, a formula is a concise way of expressing information symbolically, as in a mathematical formula or a ''chemical formula''. The informal use of the term ''formula'' in science refers to the general construct of a relationship between given quantities. The plural of ''formula'' can be either ''formulas'' (from the most common English plural noun form) or, under the influence of scientific Latin, ''formulae'' (from the original Latin). In mathematics In mathematics, a formula generally refers to an identity which equates one mathematical expression to another, with the most important ones being mathematical theorems. Syntactically, a formula (often referred to as a ''well-formed formula'') is an entity which is constructed using the symbols and formation rules of a given logical language. For example, determining the volume of a sphere requires a significant amount of integral calculus or its geometrical analogue, the method of exhaustion. However, having done t ...

Chine (boating)
A chine in boat design is a sharp change in angle in the Cross_section_(geometry), cross section of a hull (watercraft), hull. The chine typically arises from the use of sheet materials (such as sheet metal or marine ply) as the mode of construction. Rationale of chines Using sheet materials in boat construction is cheap and simple, but whereas these sheet materials are flexible longitudinally, they tend to be rigid vertically. Examples of steel vessels with hard chines include narrowboats and widebeams; examples of plywood vessels with hard chines include sailing dinghies such as the single-chined Graduate (dinghy), Graduate and the double-chined Enterprise (dinghy), Enterprise. Although a hull made from sheet materials might be unattractively "slab-sided", most chined hulls are designed to be pleasing to the eye and hydrodynamics, hydrodynamically efficient. Hulls without chines (such as Clinker (boat building), clinker-built or Carvel (boat building), carvel-built vessels) u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Hydrofoil
A hydrofoil is a lifting surface, or foil, that operates in water. They are similar in appearance and purpose to aerofoils used by aeroplanes. Boats that use hydrofoil technology are also simply termed hydrofoils. As a hydrofoil craft gains speed, the hydrofoils lift the boat's hull out of the water, decreasing drag and allowing greater speeds. Description The hydrofoil usually consists of a winglike structure mounted on struts below the hull, or across the keels of a catamaran in a variety of boats (see illustration). As a hydrofoil-equipped watercraft increases in speed, the hydrofoil elements below the hull(s) develop enough lift to raise the hull out of the water, which greatly reduces hull drag. This provides a corresponding increase in speed and fuel efficiency. Wider adoption of hydrofoils is prevented by the increased complexity of building and maintaining them. Hydrofoils are generally prohibitively more expensive than conventional watercraft above a certain disp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Epoxy Resin
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called ''epoxy''. The IUPAC name for an epoxide group is an oxirane. Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols (usually called mercaptans). These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing. Reaction of polyepoxides with themselves or with polyfunctional hardeners forms a thermosetting polymer, often with favorable mechanical properties and high thermal and chemical resistance. Epoxy has a wide range of applications, including metal coatings, composites, use in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towards ox ...

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 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.
