Apollo Mechanical Cup Hydroplane Performers
Grand Prix America
Grand Prix America Hydroplanes is a leading hydroplane racing series in North America, featuring some of the fastest boats on water. With a focus on competition, innovation, and community engagement, GPA continues to bring the best of hydroplane racing to fans across the continent.
H1 Unlimited
The Unlimiteds are powered by turbine-engines that produce around 3,000 horsepower – allowing 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.
Vintage Hydroplanes
Some of Seafair’s favorite vintage boats will thunder on the waters of Lake Washington again. Stay tuned for what boats will be making their Seafair return!
Junior Hydros – J Hydros
J stands for “Junior” and is the entry-level class of American Power Boat Association racing. J-Hydros are a little over nine feet long, weigh 300 pounds, and have a top speed of 40 miles per hour. They use a stock 13.2 cubic inch OMC or Mercury outboard engine. To participate in J-Hydro, a driver must be between 9 and 16 years old.
