Most of the H1 Unlimited hydroplane fleet calls Seattle home. The Emerald City has hosted the Unlimiteds every year since 1951. Lou Fageol won the very first Seattle race driving Stan Sayres' SLO-MO-SHUN V.
Seattle is the third oldest Unlimited race site. In terms of consecutive years of participation, the race is the longest continuously running event on the schedule -- while Detroit Gold Cup and the Madison Regatta have seniority over Seattle, there have been years both races were not held.
