Our race boats are placed into speed limit classes. The speed classes range from 60 mph up to the highest class, 130mph. The boats each vary in size, hull, and power/propulsion. In each speed bracket, the boats are not allowed to cross the maximum speed of the respective class. Speed is measured by a GPS unit on board each boat and if class speeds are exceeded, that boat is either penalized or disqualified depending on the race, or number of infractions for the day.
