At 125 mile per hour John Shewbrooks of Waverly, Ohio, spent decades competing on the American Power Boat Association Inboard Racing Tour throughout the United States and Canada. He also traveled to New Zealand and Australia for international competition. With his 2.5 litre modified inboard hydroplane, Sho nuff, John and crew would travel 25,000 miles per year in quest for their several wins and championships.
An inboard hydroplane is as a speedboat with hydrofoils (called sponsons) which raise the hull partially out of the water, whereby, the boat skims over the water at high speed, much like a rock skipping over a smooth pond. Races are held on lakes and rivers on oval courses approximately 1 mile to 1 1/4 mile in length. Either 4 or 5 laps are run to constitute a 5 mile race. The driver must be licensed through the American Power Boat Association (APBA), which is the national authority governing power boat racing in the United States. Drivers must pass a medical exam, written exam, and demonstrate acceptable driving ability. Boats are registered through the APBA where length and motor size are regulated.
