Formula 16
The Formula 16 (F16) sport catamaran is an ISAF recognised 5 m long beach catamaran with an asymmetric spinnaker setup. It is actively sailed in two modes: doublehanded with a jib (''2-up''), and singlehanded without a jib (''1-up''). Its class rules setup is very similar to those of the Formula 18 class of beach catamarans. In effect any boat that adheres to a certain limited set of general design specifications may participate in all the official class races. The two classes, F18 and F16, govern the racing of their own class compliant boats. The F16 class was founded in the spring of 2001, after it had become clear by the overwhelming success of the F18 class that formula classes would be the future in sport/beach catamarans and that a more versatile formula class was desired. In handicap racing, the F16 uses a D-PN of 63.0 Limits In the beginning the F18 class rules functioned as a template for the F16 class rules, but not much later the two rule sets started to div ...

Formula 16-2Up
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 Latin influence in English, original Latin). In mathematics In mathematics, a formula generally refers to an Identity (mathematics), identity which equates one mathematical expression to another, with the most important ones being Mathematical theorem, 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 formal language, logical language. For example, determining the volume of a sphere requires a significant amount of inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catamaran
A Formula 16 beachable catamaran Powered catamaran passenger ferry at Salem, Massachusetts, United States A catamaran () (informally, a "cat") is a multi-hulled watercraft featuring two parallel hulls of equal size. It is a geometry-stabilized craft, deriving its stability from its wide beam, rather than from a ballasted keel as with a monohull boat. Catamarans typically have less hull volume, smaller displacement, and shallower draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes. Catamarans were invented by the Austronesian peoples which enabled their expansion to the islands of the Indian and Pacific Oceans. Catamarans range in size from small sailing or rowing ve ...

Spinnaker
A spinnaker is a sail designed specifically for sailing off the wind on courses between a reach (wind at 90° to the course) to downwind (course in the same direction as the wind). Spinnakers are constructed of lightweight fabric, usually nylon, and are often brightly colored. They may be designed to perform best as either a reaching or a running spinnaker, by the shaping of the panels and seams. They are attached at only three points and said to be ''flown''. Nomenclature Informal names for a spinnaker are ''kite'' or ''chute'' (owing to their resemblance to a parachute in both construction and appearance). Boats may have more than one spinnaker, differentiated by a letter to indicate symmetric (S) or asymmetric (A) and a number to indicate size (with higher numbers indicating smaller size), e.g. ''A1'' would be a large asymmetric sail and ''S3'' would be a smaller symmetric sail. Operation A spinnaker is used for sailing with the direction of the wind. Symmetrical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formula 18
The Formula 18 class, abbreviated F18, is a non-foiling, restricted development, formula-design sport catamaran class. It was started in the early 1990s and quickly grew getting class recognition by World Sailing, with large racing fleets all over the globe. Design goals The overall objective of the class is to offer popular, safe, exciting and fair racing in 18-foot catamarans. The F18 class is a "box rule" class, which means that any boat that adheres to the limited set of general design specifications may participate in all F18 races. This has led to a score of homebuilders and professional builders to design their own F18 boats and race them in this class. However, it is the mainstream production F18 designs that have dominated the top of the class. The presence of multiple boat builders and sailmakers in the class stimulates innovation and helps to limit costs to sailors. The F18 box rule allows limited development, striking a balance between the class remaining close to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sailing (sport)
The sport of sailing involves a variety of competitive sailing formats that are sanctioned through various sailing federations and yacht clubs. Racing disciplines include matches within a fleet of sailing craft, between a pair thereof or among teams. Additionally, there are specialized competitions that include setting speed records. Racing formats include both closed courses and point-to-point contests; they may be in sheltered waters, coast-wise or on the open ocean. Most competitions are held within defined classes or ratings that either entail one type of sailing craft to ensure a contest primarily of skill or rating the sailing craft to create classifications or handicaps. On water, a sailing competition among multiple vessels is a regatta, which usually consists of multiple individual races, where the boat crew that performs best in over the series of races is the overall winner. There is a broad variety of kinds of races and sailboats used for racing from large yacht to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portsmouth Yardstick
The Portsmouth Yardstick (PY) or Portsmouth handicap scheme is a term used for a number of related systems of empirical handicapping used primarily in small sailboat racing. The handicap is applied to the time taken to sail any course, and the handicaps can be used with widely differing types of sailboats. Portsmouth Numbers are updated with data from race results, normally annually. The various schemes are not directly linked, and ratings for the same class can and often do vary in the different schemes. The most prominent Portsmouth Yardstick systems are probably those administered in the United States by the Portsmouth Numbers Committee, in the United Kingdom by the Royal Yachting Association ( RYA) and in Australia by Victoria Yachting. History The original UK Portsmouth Yardstick was developed by Stanley Milledge, who was in charge of handicapping racing at the '' Langstone Sailing Club'' in 1947 using the ''Island One'' design as the scratch boat (having a value 100). In 195 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
