The 470 is an Olympic Class Dinghy recognised by ISAF. Sailed by both men and women, it was designed in 1963 by the Frenchman André Cornu as a modern fibreglass planing dinghy.

The International 470 Class is the class of boat used for both the men's two person and women's two person dinghy events at the Olympic Games. Used as Olympic equipment since 1976, where the class was sailed as an open event before the introduction of separate events for men and women in 1988, the 470 is sailed in more than 61 nations around the world.
