MOSES LAKE, Wash. — The 2026 Moses Lake Vintage Hydroplane Test & Tune takes place on August 29–30, 2026, at Connelly Park (6671 McConine RD NE) in Moses Lake, Washington.
This free public event features vintage hydroplane runs, a car show, and food trucks, running from 9-5 each day.
The hydroplanes are from the golden age of hydroplane racing in the Pacific Northwest including four vintage unlimited’s, the Thriftway, Bluechip, Maverick and Tahoe Miss.
This is, however, not a formal race event but rather a “test and tune” which allows much more variety in staging the boats on the water.
Big and small vintage hydroplanes running on 1-2/3 mile and 1-1/4 mile courses.
On-site family activities including a car show and local food trucks.
