Inflatable catamaran racing will make its debut at Cocoa Beach during the 2026 IHRA Offshore National Championship Series, with the first event scheduled for May 14-17. The ThunderCat class, which uses outboard-powered inflatable boats, will participate in practice and qualifying sessions on May 14 and 15. This marks the first time the class has been included in the IHRA Offshore series, according to Leah Martin, president of the International Hydroplane Racing Association.
The addition of ThunderCat racing aims to expand opportunities for new competitors while maintaining high-level competition. Martin said the class offers affordability and accessibility, with boats that can reach speeds over 60 mph. "This creates a clear entry point for new competitors while still delivering high-level competition," she said in a statement. The event will take place at Cocoa Beach, a location known for its surf conditions and previous hosting of powerboat events.
ThunderCats are inflatable catamarans classified by the Union Internationale Motonautique (UIM) under the P750 designation. Each boat is about four meters long and weighs approximately 90 kg without an engine or fuel. They are powered by outboard motors ranging from 40 to 90 horsepower and require a two-person crew: one driver and one co-driver. The co-driver adjusts weight distribution to improve handling during turns.
Safety is a key feature of ThunderCat racing, with each hull composed of six independently inflated chambers. If one chamber is punctured, the remaining five keep the boat afloat, contributing to the class's strong safety record. The event is expected to attract both longtime powerboat fans and newcomers to the sport, with Martin emphasizing the importance of building a unified platform for powerboating under the IHRA.
