Current Olympic equipment

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]

History

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 ]}

Sailing

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.

Races

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]

Construction

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]
