The Unlimiteds are powered by turbine-engines that produce around 3,000 horsepower and World War 2-era Allison V-12’s that kick out around 2,500 horsepower – allowing our drivers to reach speeds of nearly 200 mph and producing a massive 60-foot tall, 300-foot long wall of water called a “roostertail” behind them. With very few restrictions, these majestic hydroplanes race in front of shorelines packed with fans on bodies of water throughout the United States.
Follow the H1 Unlimited Hydroplane Racing Series in 2023:
The season kicks off in Guntersville, Alabama, home of the Guntersville Lake Hydrofest. 2023 marks the first year of a new, ultra-fast course layout – watch for all-time speed records to be set!
From there, the boats head to Madison, Indiana, home of the only community-owned hydroplanes on the circuit for the Madison Regatta on the Ohio River.
The next stop is the Columbia River in Kennewick, Washington for the Columbia Cup and a sun-baked weekend on one of the super speedways of the series – look for speeds topping 200 mph.
After Tri-Cities, we return to Seattle for the HomeStreet Bank Cup at Seafair! This year, there is much more on the line, as Seafair hosts the APBA Gold Cup for the first time since 1987! As a “home” race for most of the H1 Unlimited teams, this is the one everyone wants to win, and when you include the Gold Cup, competition will be fierce!
If you haven’t experienced H1Unlimited hydroplane racing in person, choose an event, get down to the shore and see what makes this “the most spectacular sport on the water.”
