The UIM-ABP Aquabike World Championship is organized and promoted by H2O Racing Ltd on behalf of the Union Internationale Motonautique (UIM), the governing body of powerboating and the exclusive entity recognized by the International Olympic Committee (IOC).

Skis, by definition, are the most demanding to ride as they require high fitness levels and great physical strength as well as agility in the legs and arms.

Ski bikes are currently used in 3 different disciplines of the UIM-ABP Aquabike World Championship: Closed Circuit, Parallel Slalom and Freestyle.

Runabout bikes are designed for driving while seated and feature a saddle (located towards the front) and a rear jet or a completely closed propulsion system.

Runabout bikes are used in 5 different disciplines of the UIM-ABP Aquabike World Championship: Closed Circuit, Offshore, Endurance, Jet Raid and Parallel Slalom.

Riders are required to complete a set number of laps (varies according to racing division) at the end of which, the chequered flag is waved by marshals.

The circuit is bordered by large buoys (visible from long distances) or by natural landmarks like coastline, lighthouses, islands, rocks, etc .

On the ground, there is a medical team specialised in traumatology who are able to accompany the riders to the closest hospital to the race site.
