Biographical NoteReturn to Top
Stanley S. Sayres (1896-1956), the owner and driver of the hydroplane, moved to King County in 1932. He was in the automobile business heading the American Automobile Company, a Chrysler car dealership at 1001 Broadway in Seattle, and an auto parts store in the University District. Sayres also owned the Jen-Cel-Lite Corporation, a manufacturer of cold weather clothes. He became interested in speedboat racing in 1926 in Oregon, and his interest continued after he moved to King County, Washington. In 1949, Sayres built a 17-room home on the east side of Hunts Point near the point's north end (4450 Hunts Point Road), along with a boathouse for his hydroplanes. Hunts Point is on the east side of Lake Washington.
Sayres had owned and raced smaller boats, but he wanted to try for a world record. With this in mind, he commissioned Ted Jones to design the Slo-mo-shun IV and Jensen Motor Boat Company, at the north end of Seattle's Lake Union, to construct it. Jensen Motor Boat Company launched the 28-foot-long, 4,750-pound hydroplane in October 1949.
Driving his hydroplane, Slo-mo-shun IV , he established a world speed record (160.3235 mph) for hydroplanes on 06/26/1950.

Historical BackgroundReturn to Top
The Slo-mo-shun IV was King County's own. The owner, designer, builder, mechanics, and crew were Seattle and King County residents. The only parts of the hydroplane not constructed in Seattle were a surplus World War II airplane engine and the boat's propeller.
