H1 Unlimited has announced a new race format that will debut at the 76th Madison Regatta on the Ohio River in Madison, Indiana, July 3-5, 2026.
The change replaces draw-based positioning with a cumulative scoring system that connects every session from Time Trials through to the Final.
Mike Denslow will not renew for another two-year term as Chairman of H1 Unlimited.
He confirmed that his decision is unrelated to any individuals, board decisions, or matters concerning the organisation.
The 2025 H1 Unlimited season concluded in spectacular fashion at Mission Bay, San Diego, where fans witnessed not only the most exhilarating race of the season but also a record-breaking performance etched into hydroplane history.
