 The team was started in 1960 when industrialist Samuel F. Dupont donated one of his hydroplanes to the town in 1961 to be run in the American Power Boat Association races.The town's boat is registered as "U-6" (for APBA Unlimited class, #6) in high-points unlimited hydroplane racing since 1961, which makes them the longest-running team in the sport, although the team will change numbers if required by H1 Unlimited regulations that state the defending national champion use the U-1 designation.Through 2008 the U-6 team has used only 7 different hulls, although number 6 was used for only one race in 1988 when the new 5th Miss Madison hull crashed at San Diego in 1988.
