Mayor Wilson awarding a trophy topped with a toy bathtub to the winner of the 1974 Bathtub Races. The races were held at Crown Point Shores as part of activities celebrating San Diego's America's Finest City Week in August 1974. The boats are small watercraft designed around bathtubs or close facsimiles. The rules restrict the engine to 8 horsepower and the weight to a minimum of 350 pounds including the driver.
