I can never seem to get enough of this place. I grew up in Seattle when Unlimited Hydroplane Racing was the major league attraction every August. Thunderboats they called them, 30-foot long 180 MPH aircraft-engine powered craft, skimming on top and, often, out of the water. The rivalry between Detroit and Seattle for possession of the famed Gold Cup was greater than anything between Boston and New York in Baseball.
If you're a devotee of this high-speed sport, allow at least half-a-day to go through this place to see some legendary race boats from 1918 and into the modern era. the displays, artififacts, and films alone will take fascinate you. Great gift shop too. Very modest admission fee and minutes from Sea-Tac airport if you have a long layover between flights.
Be sure to visit the restoration shop. The friendly docent staff will give you a free tour.
