The origin of the term lies in the nomenclature that was adopted by the FIA for all of its post-World War II single-seater regulations, or formulae. The best known of these formulae are Formula One, Two, Three and Four. Common usage of "formula racing" encompasses other single-seater series, including the GP2 Series, which replaced Formula 3000 (which had itself been the effective replacement for Formula Two).

It is the highest class of inshore powerboat racing in the world, and as such, with it sharing the title of F1, is similar to Formula One car racing. Each race lasts approximately 45 minutes following a circuit marked out in a selected stretch of water, usually a lake, river, dock, or sheltered bay.
