When Edgar Kaiser won the Gold Cup with the Hawaii Kai III in 1958 he had a limited number of Custom 1/10th scale Hawaii Kai III models built for his crew members. It is 30 inches long. Over the years the Hydroplane Museum has received four of them and the Board has decided to auction off one of them. This is an extremely rare and valuable piece. This model is missing it's rudder but otherwise is in excellent condition.
