The International Monohull Open Class Association (IMOCA) was founded in 1991. Its main task is organising regattas and single-handed circum-navigation regattas. Since 1998 IMOCA is member of the ISAF (International Sailing Federation).
IMOCA designed the class regulations for a 60 foot ocean racing yacht, called IMOCA 60. IMOCA organizes the Ocean Masters World Championship and is the sanctioning authority for the Barcelona World Race.
