Inboard Hydroplanes

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.
