Handicap (sailing)
Handicap forms for sailing vessels in Yacht racing, sailing races have varied throughout history, and they also vary by country, and by sailing organisation. Sailing handicap standards exist internationally, nationally, and within individual sailing clubs. Typically sailing vessel classes are defined by measurement rules, which categorise vessels accordingly into classes of vessels, and vessels compete within their class. Handicapping allows vessels to compete across classes, and also allows vessels and crews to compete based on performance and equipment on an equal basis, by adjusting the race outcome data, to declare a ''handicap'' (adjusted) winner as distinct from a ''line honours'' (first over the finish line) winner. For some national, international, and other yacht racing events, rules such as those of the International Racing Certificate known as the International Measurement System (IMS) or the Sportsboat rule (SBR) may be specified. Others exist in different countries. ...

Yacht Racing
Yacht racing is a Sailing (sport), sailing sport involving sailing yachts and larger sailboats, as distinguished from dinghy racing, which involves open boats. It is composed of multiple yachts, in direct competition, racing around a course marked by buoys or other fixed navigational devices or racing longer distances across open water from point-to-point. It can involve a series of races with buoy racing or multiple legs when point-to-point racing. History Yachting, that is, recreational boating, is very old, as exemplified in the ancient poem Catullus 4: The yacht you see there, friends, says that she's been The fastest piece of timber ever seen; She swears that once she could have overhauled All rival boats, whether the challenge called For racing under canvas or with oars. (trans. James Michie) "Yacht" is referred to as deriving from either Norwegian ("jagt"), Middle Low German ("jaght") or from the Dutch word jacht, which means "a swift light vessel of war, commerce or p ...

Freeboard (nautical)
In sailing and boating, a vessel's freeboard is the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. In commercial vessels, the latter criterion measured relative to the ship's load line, regardless of deck arrangements, is the mandated and regulated meaning. In yachts, a low freeboard is often found on racing boats, for increased speed (by reducing weight and therefore drag). A higher freeboard will give more room in the cabin, but will increase weight and drag, compromising speed. A higher freeboard, such as used on ocean liners, also helps weather waves and so reduce the likelihood of being washed over by full water waves. A low-freeboard vessel is susceptible to taking in water in rough seas. Freighter ships and warships use high freeboard designs to increase internal volume, which also allows them to satisfy International Maritime Organization (IMO) damage stability regulations, due to in ...

Offshore Racing Congress
The Offshore Racing Congress (ORC) is an international body for the sport of competitive sailing and is responsible for the establishment and maintenance of rating and classification standards used to define offshore, that is marine as opposed to inland, yacht racing handicap categories. Ratings and Classification The ORC was established in 1969 to create a single international handicap standard to combine the two pre-existing dominant handicap standards - that of the Cruising Club of America which covered North and South Americas, and the standard of the Royal Ocean Racing Club for Europe and the Antipodes. The combined ruleset, the International Offshore Rule or IOR, was initially successful. The ORC developed International Measurement System (IMS) in the early 1990s and it was widely used to the early 2000s. This made use of a Velocity prediction program or VPP. While still maintained, the IMS has been largely superseded by the Offshore Racing Congress Rule in its Internatio ...

Union Nationale Pour La Course Au Large
The Union Nationale pour la Course au Large also called UNCL is a French yacht club UNCL was established in 1971 through a merger of the Union Nationale des Croiseurs (UNC), and the Groupe des Croiseurs Légers (GCL). UNC itself was formed at Brest in 1913 to organise offshore racing in France as this was outside of the statutes of the Yacht Club de France at that time. GCL had been formed in 1960 by Alain Maupas to organise races for smaller craft. UNCL organises races around the French coast, including the Trophée Atlantique UNCL and Trophée Méditerranée IRC UNCL, and participates in others. In co-operation with the British offshore racing club, RORC, UNCL is responsible for IRC, the principal international handicap system for yacht racing. Effective September 30, 2022 UNCL was absorbed into the Yacht Club de France The Yacht Club de France is the senior nautical club in France, and one of the most important yacht clubs in the world. History The club was established ...

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

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 ...

Dinghy Racing
Dinghy racing is a competitive sport using dinghies, which are small boats which may be rowboats, have an outboard motor, or be sailing dinghies. Dinghy racing has affected aspects of the modern sailing dinghy, including hull design, sail materials and sailplan, and techniques such as planing and trapezing. Organization of competitive dinghy sailing Dinghy racing comes under the auspices of World Sailing. Organisations such as the Royal Yachting Association, National School Sailing Association (UK) and Canadian Yachting Association (Canada) organise and regulate the sport at a national level. Sailing dinghies compete on an international, national, state, association, club and class basis, using the ISAF International Racing Rules of Sailing, which are revised every four years. There are several courses used, such as the Olympic triangle. The International Association for Disabled Sailing (IFDS)] is the body authorized by ISAF to be responsible for disabled sailing worldwide. ...

Sailboats
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. Catboat A catboat has a single mast mounted far forward and does not ca ...

Handicapping
Handicapping, in sport and games, is the practice of assigning advantage through scoring compensation or other advantage given to different contestants to equalize the chances of winning. The word also applies to the various methods by which the advantage is calculated. In principle, a more experienced participant is disadvantaged, or a less experienced or capable participant is advantaged, in order to make it possible for the less experienced participant to win whilst maintaining fairness. Handicapping is used in scoring many games and competitive sports, including go, shogi, chess, croquet, golf, bowling, polo, basketball, and track and field events. Handicap races are common in clubs which encourage all levels of participants, such as swimming or in cycling clubs and sailing clubs, or which allow participants with a variety of standards of equipment. Often races, contests or tournaments where this practice is competitively employed are known as ''Handicaps''. Handicappi ...

IRC (sailing)
IRC is a system of handicapping sailboats and yachts for the purpose of racing. It is managed by the Royal Ocean Racing Club (RORC) in the United Kingdom through their dedicated Rating Office, and the Union Nationale pour la Course au Large (UNCL) in France. IRC stands for International Rating Certificate. Originally, “IR” was an abbreviation for International Rule. However, since the Rule at that stage was not recognized under International Rule (sailing), that name was not permitted. So RORC simply decided to keep the initials as the name, and the name remained simply IRC until 2016. The IRC rule is not published, meaning the only bodies capable of calculating an IRC rating are the RORC Rating Office and UNCL Centre de Calcul in Paris (they are joint owners of the Rule). This prevents designers from attempting to design 'to the rule'. The earlier IOR was published, and often amended, resulting in widespread criticism for several reasons. Firstly, as the rule effectively d ...
