In the years before the Mariners and other local big league sports teams, Seattle had the Slo-mo-shun IV hydroplane – “Slo-mo” for short. This speedy vessel’s designers, builders and racers, Anchor Jensen, Ted Jones, Stan Sayers and Lou Fageol became household names when they set the world water speed record on Lake Washington and won the coveted Gold Cup in Detroit in 1950.

When the three men met early in 1949 at a Seattle sailboat shop, none of them could have foreseen the peculiar and far reaching consequences of their joint venture to build a better race boat. Slo-Mo-Shun IV was indeed better than any previous race boat. But she was more than that, Slo-Mo IV touched the hearts of thousands who cheered her on and changed forever the way generations of Seattleites feel about the first week in August.
