The UIM Class 1 World Powerboat Championship (also known as Class 1) is an international offshore powerboat racing category organized by the Union Internationale Motonautique (UIM). The series features catamarans competing in multi-event seasons sanctioned by the UIM.
The championship was established in 1964, following the development of modern offshore powerboat racing in the mid-20th century. It has operated under both single-event and multi-event formats, and now runs as a season-long points competition. Class 1 boats are composite catamarans powered by standardized high-output engines and crewed by a driver and throttle man. World Championship titles are awarded based on cumulative race results across each season.
