Hydroplane boat races were popular in Coeur d’Alene, and around Washington, throughout the ’50s and into the ’60s. This summer marks the return to racing 44 years after the popular sport ended. Hydro races are planned southeast of downtown as part of the Diamond Cup Regatta during Labor Day weekend.
The Unlimited hydroplanes are lowered by crane into Coeur d’Alene Lake, near Tubbs Hill, ready for the 1962 Diamond Cup race. The first Diamond Cup was held on the lake in 1958 with about 30,000 spectators. The last race was held in 1968. Race boats from all over the country participated.
