The ILCA 7 World Championship, until 2020 the Laser World Championship, has been held every year since 1974, They are organized by the host club on behalf of the International Class Association and recognised by World Sailing. The class has been used in every Olympics since 1996 and has varied between being an "open" event meaning any gender or as currently a male only event so the World Championships also has a gender restriction.
