is dedicated to the individuals who made the Slo-mo-shun legacy possible, and to those who have contributed to hydroplane racing in Seattle..

Over the span of almost 10 years, Slo-mo-shun IV & V came out of obscurity to dominate the unlimited hydroplane racing world,
and then just as quickly vanish from the competitive racing circuit. celebrates all that was the mid-20th century hydroplane phenomenon in Seattle -

speed, craftsmanship, personalities, and the powerful roar of piston engines.

We hope you enjoy!
