H1 Unlimited Hydroplane Racing Series

H1 Unlimited hydroplanes are the fastest racing boats in the world and their races are sanctioned by the American Power Boat Association, doing business as H1 Unlimited.  The majority of the H1 boats are powered by turbine-engines that produce 3,000 horsepower, allowing the H1 Unlimited hydroplanes to reach speeds of nearly 200 mph, 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 2018 H1 Unlimited Hydroplane Racing Series as the season kicks-off in Guntersville, Alabama, home of the inaugural Guntersville Lake Hydrofest and the Race for the Southern Cup.

From there, the boats head to Madison, Indiana, home of the only community-owned hydroplane on the circuit for the Indiana Governor’s Cup Madison Regatta on the Ohio River.

The next stop is the Columbia River in Kennewick, Washington for the HAPO Columbia Cup and a sun-baked weekend on one of the super speedways of the series – look for speeds topping 200 mph.

Seattle, Washington hosts the fourth race, the Albert Lee Appliance Cup at Seafair on the historic Lake Washington hydroplane course. The Seafair event always results in great racing as a majority of the teams have home bases and sponsors in the greater Seattle area, and a win in their hometown is tops on every participant’s list.

At the fifth race of the year, the Spirit of Detroit Hydrofest in Detroit, Michigan you will see some outstanding racing on one of the most spectacular courses on the circuit –the Roostertail Turn.  It is the closest racecourse to the shore and should be experienced at least once in your life.

The season finishes on beautiful Mission Bay in San Diego, California at the HomeStreet Bank Bayfair Cup. The finale is sure to include a battle for the season high points championship, guaranteeing deck-to-deck battles until the final checkered flag!

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.”
