The Formula 1 Powerboat World Championship (also F1) is an international motorboat racing competition for powerboats organised by the Union Internationale Motonautique (UIM) and promoted by H2O Racing, hence it often being referred to as F1H2O. 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.
Qualifying periods decide the formation of the grid, and timing equipment records the performance of competitors to decide the final classification and allocation of championship points.

Inshore powerboat racing is a form of water-based motorsport using powerboats in sheltered or inland stretches of water, including lakes, rivers, docks and sheltered bays. It is often referred to as circuit powerboat racing because of the frequency of inshore races to use the format of a circuit loop, around which boats race for a number of pre-determined laps.
International races and championships are administered by the Union Internationale Motonautique (UIM) while national events are organised by the relevant country's own powerboat association.
