The IHRA Offshore Powerboat Series is a new, professional, multi-day marine motorsport racing championship debuting in the 2026 season. Sanctioned by the International Hot Rod Association (IHRA) following its late 2025 acquisition of Powerboat P1 USA/P1 Offshore, the series aims to unify American offshore racing under a single, well-funded platform. The series is known for its high-profile launch, boasting a $2,000,000+ total prize purse for its inaugural 2026 season.
