What Is Race World Offshore?
Race World Offshore (RWO) organises professional offshore powerboat racing events in the United States under full APBA sanction. Founded and led by Larry Bleil, RWO produces the Key West World Championship, the most prestigious offshore powerboat event in North America, alongside a national championship series spanning Atlantic City, Michigan City and Clearwater.
On 9 March 2026, RWO and the UIM announced a 10-year partnership making RWO the official promoter of the UIM Offshore World Championship Series in North America. From 2026, RWO events award official UIM Class 1 and Class 2 Offshore World Championship titles alongside APBA Super Cat World Championship honours, connecting North American offshore racing directly to the global UIM world championship framework for the first time.

The UIM Partnership
The 10-year agreement announced in March 2026 is a significant structural change for offshore powerboat racing in North America. Prior to 2026, RWO events awarded APBA national titles. The UIM partnership elevates the series to world championship status, with RWO events now counting toward the official UIM Offshore World Championship Series standings in Class 1 and Class 2.
The agreement was confirmed by UIM President Dr. Raffaele Chiulli and provides for long-term stability, venue expansion, enhanced media coverage including digital streaming, and unified rules aligned between APBA and UIM standards. It is part of the UIM’s broader strategy to strengthen the North American presence of the offshore world championship alongside its European and Middle Eastern events.
