The IMOCA 60 are a type of monohull sailing yachts administrated by the International Monohull Open Class Association (IMOCA). The monohulls are high-performance racing boats, designed principally for single-handed competition. Several high-profile yacht races are based around these boats, such as the VELUX 5 Oceans Race, the Vendée Globe and the Barcelona World Race (circum-navigations), the Calais Round Britain Race (crewed race around the British Isles), and the Route du Rhum, the Transat Jacques Vabre, the Quebec-St Malo the Single-Handed Trans-Atlantic Race, and the Europa Race.
