The H1 Unlimited Hydroplane Series races the fastest circuit racing boats in the world, with speeds topping 200 MPH on lakes and rivers in the United States.

Our turbine and piston-powered hydroplanes pump out over 3000 horsepower and throw 40 foot high, 200 yard long roostertails that you have to see to believe!

Follow the entire 2021 circuit with races in Guntersville, AL, Madison, IN, Kennewick, WA, and San Diego, CA.

The app allows you to view and search our extensive database of videos, results, statistics, driver bios, team information and other resources to get up to speed on the most exciting sport on the water!

During the racing season, we will be updating our race schedules, results and points, and even you bring live streaming from our races.

The H1 Unlimited app will be your one-stop source to follow the sport either from the beach or from your couch!
