The International One Design (IOD, International) is a class of sail boat developed in 1936 for yacht racing . It is a 33-foot open-cockpit day sailer used for day racing , rather than for overnight or ocean races. Popularised prior to the Second World War , the International One Design class is considered a classic one today.
53-576: The International class sloop was created by American yachtsman, Cornelius Shields , as he sought to create a new one design yacht for the Amorita Cup series of team races between Bermuda and Long Island Sound . While in Bermuda one spring, he looked at a Bermudian Six Metre , the Saga , owned by Kenneth and Eldon Trimingham , and knew instantly that he had seen the prototype of a racing class boat. Inspired by
106-664: A development class , the classic example being America's Cup 12-metre class , or to the box rule used, for example, in the TP 52 class. A further category, the formula based class setup, is sometimes confused with one design. The Mini Transat 6.50 , the Volvo Open 70 monohull, the large ORMA trimaran, and the Formula 18 racing beach catamaran are the exponents of the formula approach. Class-legal boats race each other without any handicap calculations in both setups. However, under one design
159-438: A racing class that consists of just one model or design of a 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
212-405: 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. 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
265-551: A World Championship (the venue of which rotates between the fleets), a North American Championship, Bermuda Race Week, the Nantucket Invitational, a European Championship and occasional Team-racing championships hosted by individual fleets. Yachts from the International One Design class are used for the annual Bermuda Gold Cup as part of the professional World Match Racing Circuit. The current (2024) World Champion
318-618: A combination of discipline, equipment, gender and sometimes categories. These criteria are defined by the race purpose. The following are the main disciplines: Common categories of equipment include the following: dinghies , multihulls , keelboats , sailing yacht , windsurfers , kiteboarding and radio-controlled sailboats . Within these categories normally specific class or rating system are used. The majority of sailing events are "open" events in which males and females compete together on equal terms either as individuals or part of team. Sailing has had female only World Championships since
371-461: A general rule, the tolerances are strictest in smaller boats like dinghy classes and small keelboats. In some cases the tolerances are specified in a confidential Building Specification and often everything is designed and produced at the same factory or a very few factories. Examples are the Laser , Melges 24 , and several small keelboats designed by Nathanael Greene Herreshoff, such as the 12½ . In others
424-456: A large section of the sport. Almost any boat can be sailed though some are more suitable for larger ranges of disabilities or specific categories of impairment. World Sailing is also responsible for disabled sailing worldwide under the guidance of its own brand Para World Sailing. This is since the merger of International Association for Disabled Sailing (IFDS) in November 2014, and re-forming of
477-511: A lifting boiler plate capable of being lifted. The boat was called The Water Wag . The idea was quickly adopted by sailors in Ireland, England, India and South America. The Water Wag Club still thrives in Dun Laoghaire, Co. Dublin. The Solent One Design Class was one of the earliest one-design classes formed after discussions took place in 1893 and subsequent years. It quickly became popular, and
530-715: A more joyous day on the water. The wind was from the northeast, light in the morning and then stronger at mid-day, so we had a chance to try her out under a variety of conditions. The boat was a delight to handle, and balanced perfectly. I felt great satisfaction at this -- the planning and hope and care hadn't been in vain." The Internationals quickly spread. Bermuda took delivery of seven in January 1937. The next year's fleets were established in Marblehead, Massachusetts and Northeast Harbor, Maine , followed by fleets in Norway and Cowes . During
583-494: A one-design version of Saga. He negotiated with Aas to reduce the size of the Saga's design to produce a 33-foot (10 m) racer. The resulting design was smaller than the Saga, with less displacement, but greater beam of 6 ft 9 in (2.06 m). It measured 21 ft 5 in (6.53 m) in at the waterline, had a draft of 5 ft 4 in (1.63 m), and displaced 7,120 lb (3,230 kg). The mast

All teams compete in nearly identical Dallara SF23 models, but use engines supplied from Honda and Toyota , preventing it from being a true spec series. There are two primary methods of competition in sailboat racing : One-design and handicap racing (e.g. Portsmouth Yardstick , Performance Handicap Racing Fleet and Leading Yard Stick ). One design refers to
689-547: Is Jonathan Farrar, representing the Fishers Island Fleet. Since its founding, the International Class has remained committed to the tradition of testing sailing skills in equally equipped yachts. The Class' extensive one-design rules endeavor to ensure that the hulls, rigs and sails of the racing yachts are near equal as possible. All International owners agree to honor this Class principle. With any racing yacht,
742-443: Is composed of "Member National Authorities" (MNA's) from over 140 countries all of whom have the right to make submissions to determine World Sailing's policies. Persons with a physical impairment who are interested to learn to sail are encouraged to locate their national World Sailing Member National Authority (MNA), Disabled Sports Organization, or visit the local sailing club, as World Sailing seeks to people with disabilities into
795-499: Is permitted. Usually fleets adopt a sail purchase schedule that only requires the purchase of one sail per year. The result of this unique sail purchase program is a racing fleet of equally equipped boats that are maintained at a low cost to the individual owners. To further equalize the playing field during International and Interfleet regattas, a change-boat series is presented by the host fleet. Competitors do not bring their own boats to such an event, rather they are invited to sail in
848-556: Is usually shown by his final standing in a contest. What could be more indicative of this when pilots are flying identical sailplanes with identical performance. One-design competition is the sure test of soaring skill." Other one-design gliders have included those made in Russia by Aviastroitel , in Poland by Warsztaty Szybowcowe Orlik , and Germany, where for example the DFS Olympia Meise
901-485: The 1970s to encourage participation and now host more than 30 such World Championship titles each year. For the 2016 Olympics, compulsory mixed gender in the event was added for the first time. In addition the following categories are sometimes applied to events: World Sailing is now most familiar to sailors for defining the Racing Rules of Sailing (RRS), the international standard used to define competition rules and
954-545: The 1970s with the introduction of laminate construction using fibre-reinforced plastic (FRP) and mold building technology. This process allowed the mass production of identical hulls of virtually any size at a lower price. The one-design design idea was created by Thomas Middleton of the Shankill Corinthian Club located 10 miles (16 km) south of Dublin, Ireland in 1887. He proposed a class of double ended open dinghies of simple clincher construction in pine with
1007-513: The 20+ approved builders on four continents being of identical speed, for example at the 2017 World Championship. In medium- to large-sized boat classes, One design would refer to conformance to a standard specification , with the possibility of alterations being allowed as long as they remained within certain tolerances. Examples of this are the Dragon , J/24 , Etchells , H-boat and the Farr 40 . After
1060-628: The Classes used for the Olympic Games, World Sailing arrange the following events: Sailing as an equipment based sports allows one of the largest ranges of paralympians to compete under equal terms. Sailing was included for the first time in the Atlanta 1996 Paralympic Games program as a demonstration event. It became a full medal sport at the Sydney 2000 Paralympic Games up to 2020 were IPC removed sailing from
1113-736: The National Register of Historic Vessels of the United Kingdom. She is kept in Lymington where she is still racing and winning on the Solent. Conversely the Howth 17 , designed just four years later by Sir Walter H. Boyd of Howth , Co. Dublin is still actively raced and is the oldest one-design racing keelboat still sailing as designed. While fifteen of the current fleet were built from 1898 to 1914, new boats can still be added, most recently in 2017. As

The rational was given as follows: "The creation of a single governing body for Member National Authorities (MNAs) and sailors will better serve the needs and interests of sailors with disabilities, and provide consistency within the sport, from relationships with the World Anti-Doping Agency (WADA) to technical support and operational efficiencies." The IFDS Foundation
1219-699: The Yacht Racing Association (now the Royal Yachting Association ) wrote to the Yacht Club de France , pointing out the desirability of holding a conference for the purpose of devising an International Rule of Measurement for Racing Yachts acceptable to all European countries. As a result, an International Conference of Yacht Measurement was held in London in January and June 1906, at which the Metre Rule
1272-621: The advantages of one-design to the sport of competitive glider racing . The most successful of these has been the Schweizer 1–26 class with 700 aircraft completed and flown between 1954 and 1981. Schweizer Aircraft principal Paul A Schweizer was a proponent of the One-design concept. He intended the company's 1–26 to be the aircraft to establish a one-design class in the United States. He wrote: "The true measure of pilot ability and experience
1325-462: The beauty of the Six Metre yacht and its performance, Shields envisioned using it as the basis of a one design racing class that would have the advantages of both limiting the upwardly-spiraling costs of yacht racing and putting competing crews on an equal footing as far as equipment was concerned. Shields commissioned Saga's designer-builder, Bjarne Aas of Fredrikstad , Norway , to develop plans for
1378-692: The beginning. Soon there were thirty five IODs racing in Long Island Sound. The class took hold in and was used for the first ever competition for the Amorita Cup . In the next 28 matches, from then to 1964, held to compete for the cup (21 in Bermuda, and 8 on Long Island Sound), the Americans won 13 times, and the Bermudians 16. Today IODs are actively raced in twelve local fleets in North America and Europe. Representatives of those fleets annually compete in
1431-483: The boats are virtually identical except in details. At the same time, the formula setup allows the boats to differ much more in design while keeping a few important specifications the same. As a result, the identifier "One design" has been used more and more exclusively to denote a class that races only identical boats. Having a rigid one-design specification keeps design experimentation to a minimum and reduces cost of ownership . The popularity of one-design increased in
1484-448: The boats of the host fleet. Boats are rotated after every race, or at some events, each day. To make sure that no competing team gain an advantage through this process, the boats are distributed by random drawing and any local representative is prohibited, by rule, from sailing their own boat. In 1946, Bill John, William S. Cox, George Hinman, Arthur Knapp Jr., A.E. "Bill" Luders Jr. , Emil Mosbacher Jr. and Roderick Stephens Jr. codified
1537-514: The ethos of the class to prevent it moving away from its intended single design nature. This was achieved partly by ensuring only the original builder could produce boats for the class. Today, there are two authorised builders of boats for this class: Tjorns Yacht Service, in Sweden, and South Shore Marine in Chester Nova Scotia. The most recent all wooden IOD, built from the original 1936 drawings,
1590-484: The first class awarded International Classic Yacht status by the International Sailing Federation (ISAF). IOD Racing commenced on Long Island Sound during the summer of 1937. The very first trophy awarded for and IOD race was won by Allegra Knapp, sister to famed American sailor Arthur Knapp. Shields' determination to keep the competition on a man-to-man basis maintained the high quality of racing from
1643-551: The first six inductees for the ISAF Sailing Hall of Fame. At the 2015 annual conference in Sanya , China, there were seven further inductees. The Beppe Croce Trophy is presented to an individual who has made an outstanding voluntary contribution to the sport of sailing. The roll of honour is an impressive one, including multiple Olympic medallists, rules gurus and designers, and all have dedicated an outstanding amount of time to

The main annual award the " Rolex World Sailor of the Year " that is sponsored by ROLEX in the following categories: When a crew of two or three people is nominated, the awarded is presented to the entire crew. When larger crews win the award, normally only the skipper is recognised. On 5 November 2007 in Estoril , Portugal, the International Sailing Federation announced

NASCAR is much in the same boat, with three distinct bodies (Chevrolet, Ford and Toyota) and four distinct engines ( Hendrick , ECR , Roush Yates , TRD ) available in competition. Additionally, while IndyCar cars are all virtually identical Dallara DW12 models, the two distinct engine designs available from Chevrolet and Honda prevent IndyCar from being

Para sailing regattas for para sailors likewise follow the World Sailing rulebook with a minor change to permit things like powered adaptations. Strict classification requirements are enforced in the Paralympic Games for fair competition in Paralympic-class keelboats. The key documents under control of World Sailing are: Like all sports federations, World Sailing
1855-403: The hull length overall (LOA) exceeds 27 feet (8.2 m), people generally refer to the boat as an offshore one-design boat or yacht. In other classes, the one-design class may have organized around an existing fleet of similar boats that traditionally existed together often for commercial purposes such as sailing canoes, dhows , and skipjacks , or boats that developed a common hull form over
1908-464: The keel. Cutter rig with 6 ft bowsprit. Designed by H. W. White, ten were built in 1895/6 by Messrs. White Brothers of Itchen Ferry, Southampton and another twelve were built in the following year. The class enjoyed ten years of keen racing but the Metre Rule, which was introduced in 1907 effectively killed the class. The only boat still afloat is Rosenn, formally Eilun, sail number 6. Now, fully restored, she has been identified as meriting inclusion in
1961-516: The largest contributor to variable costs are the sails. A boat with newer sails will almost always have a greater speed potential than a boat with older sails of the same design. To keep costs low and ensure that each boat is racing with the most equal sails possible, the IOD class has evolved a very specific sail purchase program that is required to be implemented by each local fleet. The Class encourages each local fleet to develop sails for their boats that suit
2014-426: The paralympic program. Work continues to get sailing reinstated for the 2028 Paralympics. Each World Sailing class is entitled to hold a world championship The following World Championships are held: Sailing is a versatile sport that can accommodate many types of disability primarily because it is equipment based. Sailing is one of the few sports where disabled sailors compete on equal terms to able body sailors in
2067-404: 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
2120-508: The specific characteristics of their local sailing area. Unlike many other one-design fleets, however, individual boats, are not granted free license on how frequently they replace their sails. Instead, each local fleet votes each year on what sail, if any, will be purchased before a given season. The chosen sail (mainsail, jib or spinnaker) is ordered in a single lot from the local fleet's official sailmaker, who pledges to make them as near equal as possible. No recutting, or use of alternate sails
2173-578: The specification is published but the boats may only be produced by licensed manufacturers with usually only one builder in any country or region. Examples are the Olympic Finn and 470 but in both these classes a single manufacturer has succeeded in building faster boats than all other manufacturers. However, in the Optimist dinghy, one of the world's largest classes, a tighter specification introduced in 1995 /with ongoing scrutiny has resulted in boats from

After the liberation of Norway, construction resumed at Fredrikstad with boats going to San Francisco , Sweden , France , Oyster Bay , and Cowes. Fiberglass construction was introduced in the 1960s with great care taken by the class to ensure that the wood and glass yachts could race on an equal basis. Today, there are twelve fleets racing around

In contrast to 'one-design', other sailboats race under a variety of handicapping rules and formulas developed to allow different type boats to compete against one another. Formula rules include the Square Metre Rule , the Ton class , the Universal Rule , and the Metre Rule . Handicap rules include Portsmouth Yardstick , PHRF , IOR , IMS , IRC , Americap and LYS . There have been several attempts to bring

With the backing of the enthusiastic Shields, the boat was quickly adopted by the top racers on Long Island Sound. The first of the initial order of 25 yachts was delivered at City Island , New York in December 1936. "I finally arranged to sail her the week after Christmas...the first time anyone had sailed an International,” recalled Shields, many years later. “I don't think I've ever had

From 1906 to 1946 a chairman was elected from time to time to orchestrate the annual meetings. Vice presidents have been elected since 1955. There are four types of race officials used to conduct sailing events recognised by World Sailing as follows: World Sailing hold
