The 470 (Four-Seventy) is a double-handed monohull planing dinghy with a centreboard, Bermuda rig, and centre sheeting. Equipped with a spinnaker, trapeze and a large sail-area-to-weight ratio, it is designed to plane easily, and good teamwork is necessary to sail it well. The name comes from the boat's length of 470 centimetres (4.7 m; 15 ft 5 in).
The 470 is a World Sailing International Class and has been an Olympic class since the 1976 games. [1]
The 470 was designed by the Frenchman André Cornu in 1963 (four years after the 420, its smaller sister) as a modern fibreglass planing dinghy to appeal to sailors of different sizes and ages. This formula succeeded, and the boat spread around the world. In 1969, the class was given international status and it has been an Olympic class since 1976. In 1988, the first Olympic women's sailing event used the 470.[ citation needed ]
To sail the 470, good physical fitness but not too much physical strength is required. The optimal weight of the combined crew ranges between 110 and 145 kg, making it a suitable boat for men, women and youth teams. Due to various options for sail trimming one can sail the boat well at 1 to 6 Beaufort scale, slightly above by experienced teams. For racing the 470 is a tactically demanding class, since differences in boat speed are small and the boat does not lose much speed during manoeuvers. [2] Good teamwork between helm and crew is essential for successful racing.
World and Continental Championships are organised every year with separate starts for women and men/mixed teams. There is also a World Championship for juniors and a Master World Championship. The 470 is used in regional championships such as the Asian, Mediterranean, and PanAm Games. Entries are limited in important international races, encouraging more competition by requiring qualifying races in most countries.[ citation needed ]
In the World Championships more than 30 countries have been represented. There are 65 member nations in the International Class Association and more than 40,000 boats have been built in 20 countries.[ citation needed ]
The 470 may be raced in a mixed fleet of boats, its performance being adjusted by the Portsmouth Yardstick handicapping scheme. In the RYA-administered scheme, the 470 has a Portsmouth number of 973. [3] In the US Sailing-administered scheme, it has a D-PN of 86.3. [4]
The 470 is a strict one-design class, and its builder must be approved a Licensed Builder by World Sailing. The class design may evolve, but its intent is to use proven, economical, and environmentally sound materials, currently fibreglass with integral buoyancy tanks for the hull. [5]
The 470 dinghy is 4.70 m (15 ft 5 in) long with a 6.76 m (22 ft 2 in) mast. Its weight without sails is 120 kg (264 lb 9 oz). [2]
At the Olympic Games, the 470 Class was initially an open class, but since the 1988 games there have been separate events for men and women. Since 2008 each consists of a 10-race series, with teams being awarded points on a point-per-place system, and each team's worst result being discarded. At the 2024 Olympics, the 470 will be sailed by a mixed crew only. [6]

The Tornado is a double handed multihull class recognised as an International Class by the International Sailing Federation. It was used for the Catamaran discipline at the Olympic Games from 1976 to 2008.
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.
The Laser is a class of single-handed, one-design sailing dinghies using a common hull design with three interchangeable rigs of different sail areas, appropriate to a given combination of wind strength and crew weight. Ian Bruce and Bruce Kirby designed the Laser in 1970 with an emphasis on simplicity and performance.
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 Optimist is a small, single-handed sailing dinghy intended for use by young people up to the age of 15.
The 49er and 49er FX is a two-handed skiff-type high-performance sailing dinghy. The two crew work on different roles with the helm making many tactical decisions, as well as steering, and the crew doing most of the sail control. Both of the crew are equipped with their own trapeze and sailing is done while cantilevered over the water to the fullest extent to balance against the sails.
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 Laser Standard or ILCA 7 is a popular one-design class of single-handed sailing dinghy, originally built by Performance Sailcraft Canada. The laser is cat rigged, with a single mainsail and is a simple, light and fast boat to sail. The Laser Standard is the original of the Laser family of dinghies, which also includes the Laser Radial and Laser 4.7, both of which use the same hull, but have smaller rigs.
The International 420 Dinghy is a sailing dinghy popular for racing and teaching. The hull is fiberglass with internal buoyancy tanks. The 420 has a bermuda rig, spinnaker and trapeze. It has a large sail-area-to-weight ratio, and is designed to plane easily. The 420 is an International class recognised by World Sailing. The name refers to the boat's length of 420 centimetres.
The Cadet is a class of sailing dinghy designed to be sailed by two children up to the age of 17. It is a one-design class, originally designed by Jack Holt in 1947. Cadets are sailed worldwide in more than 40 countries.
The Fireball is a British sailing dinghy that was designed by Peter Milne as a one-design racer and first built in 1962.
The RS300 is a modern racing sailing dinghy made by RS Sailing. The RS300 is a one-design, single-handed, hiking dinghy with a PY of 972. Designed by Clive Everest and first produced in 1998, it is inspired by the International Moth, of which Everest was a successful designer.
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 Splash Dinghy is 3.5 m in length and all boats are identical, thus, as is typical in One-Design classes, the sailor's ability rather than equipment is emphasised fleet racing. The boats employ an un-stayed mono rig with a sail area of 6.3 m2, which makes the class easy to handle by sailors ranging from 45 to 80 kg. This, combined with the low hull weight of 55 kg, allow the class to serve as a stepping stone between the Optimist Dinghy and boats such as the Laser Radial, suiting sailors in the age range from 13 to 21 years.
The Access 303 is a single or two crew sailing keelboat, which is recognised by the International Sailing Federation as an international class. It is typically regarded as being a beginner's dinghy.
The 470 World Championships have been held every year since 1970 and organised by the club on behalf of the International 470 Class Association and recognized by World Sailing. When the Championship forms part of the ISAF Sailing World Championships.
