The International 5.5 Metre class was created to yield a racing keel boat giving a sailing experience similar to that of the International 6 Metre Class, but at a lower cost.
The main class regulation is a restriction on a single quantity output from a formula involving the boat's rating length L, weight (expressed as a displacement D) and sail area S; the regulation states that the output of this formula must not exceed 5.500 metres. There is considerable scope for variations in design while still meeting this restriction, and as a result each 5.5 metre boat is unique.
If the design parameters of a proposed new boat result in a formula output exceeding 5.5 metres, then one or more of the parameters must be suitably adjusted. Performance data gained from testing models towed in a long water tank (referred to in yacht design as Ship model basin) can suggest optimal combinations of parameters. The 5.5. metre rule is a variant of the International Rule (sailing) that was established already in 1907. The 5.5. is therefore closely related to larger metre boats such as the 6mR, 8mR and the 12mR.
Since 2010 the 5.5 Metre is one of the Vintage Yachting Classes at the Vintage Yachting Games.
The 5.5-metre class was a redesign of the 6-metre class by Charles E. Nicholson in 1937. The first boats conforming to the 5.5-metre rule were built in 1949. There had been an earlier attempt to build a cheaper alternative to the Sixes. In 1929 the 5-metre class was established by the French "Union de Societes Nautique Francaise" and the class was accepted in London. It achieved a position as the smallest new international metre class and some hundreds boats were built. Nevertheless, the 5 metre never managed to achieve an Olympic status. The 5.5-metre class replaced it quickly and was raced in Olympics for first time in 1952 Summer Olympics in Helsinki. The Scandinavian Gold Cup has also been competed with 5.5m boats since 1953. 5.5 metre boats replaced the International 6-metre at the 1956 Olympic Games held in Melbourne, Australia. The 5.5 metre participation in the Olympic sailing events continued at the 1960 Olympic Games and 1964 Olympic Games. During the 1960s it however began to draw similar criticism as preceding six-metre class - namely, increasing costs - and the boat lost Olympic status after 1968 Olympic Games, due to excessive design and building costs of one off boats, marking the end of development class keel boats in Olympic regattas. However, the class remained active thereafter and 5.5-metre boats are still very actively raced.
The measurement formula is given in the 2006 International Five Point Five Metre Rating Rules:

The object of the International 5.5 Metre Class Association is to promote and develop 5.5 Metre racing throughout the World. The first President of the association was Mr. Owen Aisher. [86]
Since the development of the class spanned more than half a century the early boats are not competitive to race against the modern designs. Therefore, the association made, in 2007, divisions in the class based upon age of the boat: [87]
During major races there are separate trophies per fleet, however if a classic fleet boat beats the modern fleet, the classic fleet boat wins the modern fleet trophy.
The Optimist is a small, single-handed sailing dinghy intended for use by young people up to the age of 15.
The International 2.4mR is a one-person keelboat. The class is a development class governed by the 2.4mR rule. The rule controlled by World Sailing is one of the few classes designated as an International Class. The International 2.4mR Class rule is closely related to the International 12mR class rule that was used at the America's Cup.
The Laser Radial or ILCA 6 is a popular one-design class of small sailing dinghy, originally built by Laser Performance. It is a singlehanded boat, meaning that it is sailed by one person. The Laser Radial is a variant of the Laser standard, with shorter mast and reduced sail area, allowing light sailors to sail in heavy winds. The International Class is recognised by World Sailing.
The International 505 is a One-Design high-performance two-person monohull planing sailing dinghy, with spinnaker, utilising a trapeze for the crew.
The 12 Metre class is a rating class for racing sailboats that are designed to the International rule. It enables fair competition between boats that rate in the class whilst retaining the freedom to experiment with the details of their designs. The designation "12 Metre" does not refer to any single measurement on the boat, and is not referencing the vessels overall length, rather, measures the sum of the components directed by the formula which governs design and construction parameters. Typically 12 Metre class boats range from 65 to 75 feet in length overall; they are most often sloop-rigged, with masts roughly 85 feet tall.
The J Class of racing yachts were built to the specifications of Nathanael Herreshoff's Universal Rule. The J Class is considered the apex of the era when the Universal Rule determined eligibility in the America's Cup.
The Universal Rule determined a yacht's eligibility to race in the America's Cup from 1914 to 1937 and for this the J-class was chosen. Boats built according to the rule reached their peak in the large J-class yachts. This Rating Rule is intended to calculate a rating for yachts, which can then be used to calculate its Time Correction Factor (T.C.F.) in order to have disparate yachts racing against each other. The first boat said to be built under the universal rule was Herreshoff's Doris built in 1905.
The International rule, also known as the Metre rule, was created for the measuring and rating of yachts to allow different designs of yacht to race together under a handicap system. Prior to the ratification of the International rule in 1907, countries raced yachts under their own national rules and international competition was always subject to various forms of subjective handicapping.
The 29er is a two-person high performance sailing skiff designed by Julian Bethwaite and first produced in 1998. Derived from the Olympic class 49er class, it is raced in the ISAF Youth Sailing World Championships. The 29er is able to reach high speeds fairly quickly by having a sleek and hydrodynamic hull and will often exceed the wind speed when planing both up and downwind.
The Soling is an open keelboat that holds the World Sailing "International class" status. The class was used from the 1972 Olympics until the 2000 Olympics as "Open three-person keelboat". Besides the Olympic career of the Soling the boat is used for international and local regattas as well as for recreational sailing. The Soling is managed by the International Soling Association under auspician of World Sailing since 1968.
Sailing has been one of the Olympic sports since the Games of the I Olympiad, held in Athens, Greece, in 1896. Despite being scheduled in the first Olympic program, the races were canceled due to severe weather conditions. Apart from the 1904 Summer Olympics, sailing has been present in every edition of the Olympic Games.
The Dragon is a one-design keelboat designed by Norwegian Johan Anker in 1929. In 1948 the Dragon became an Olympic Class, a status it retained until the Munich Olympics in 1972. The Dragon's long keel and elegant metre-boat lines remain unchanged, but today Dragons are constructed using the latest technology to make the boat durable and easy to maintain. GRP construction was introduced in 1973 and the rigging has been regularly updated.
The RS Feva is a two-person sailing dinghy designed by Paul Handley in 2002. It is manufactured and distributed by RS Sailing. The RS Feva is an International Sailing Federation (ISAF) International Class, a Royal Yachting Association (RYA) Supported Junior Class, and has been selected by the Dansk Sejlunion and Norges Seilforbund for major sailing growth projects.
The International Six Metre class is a class of classic racing yachts. Sixes are a construction class, meaning that the boats are not identical but are all designed to meet specific measurement formula, in this case International rule. At their heyday, Sixes were the most important international yacht racing class, and they are still raced around the world. "Six metre" in class name does not, somewhat confusingly, refer to length of the boat, but product of the formula; 6mR boats are, on average, 10–11 metres long.
Peter Burling is a New Zealand sailor. He was the 2021 America's Cup winning skipper and helmsman, and the 2017 America's Cup winning helmsman of Team New Zealand. Burling won an Olympic gold medal in the 49er class at the 2016 games and silver medals in the 2012 and 2020 Olympics.
Andrew Blair Tuke is a New Zealand sailor who won the 2021 Americas Cup Held in Auckland and also won the 2017 Version held in Bermuda. He also won the gold medal at the 2016 Summer Olympics, and the silver medal at the 2012 Summer Olympics in the 49er class alongside Peter Burling.
The 5.5 Metre World Championship are international sailing regatta in the 5.5 Metre class organized by the host club and the International 5.5 Metre Class Association and recognized by the World Sailing.
The 6 Metre World Cup are biennial international sailing regattas in the 6 Metre class organized by the International Six Metre Association.
