The (1st annual Diamond Cup Regatta) will be Aug. 20-22 with the cooperation of the Hydroplane and Race Boat Museum in Kent, Washington. Four vintage unlimited hydroplanes will be displayed around the community and at the Museum of North Idaho. Tentatively scheduled to appear are the 1968 Miss Budweiser, the 1967 Miss Budweiser, the "Green Dragon" Miss Bardahl and the Miss Wahoo. Each of these boats competed in Diamond Cup racing including racing under different owner/sponsor teams. These boats were state of the art 40-50 years ago. They are powered by WWII fighter plane V-12 engines and capable of running at speeds in the 190 mph range/The Guide to North Idaho. More here.
