On Sept. 20-21, the Northwest Powerboat Association (NWPBA) will have vintage hydroplanes on the water from 9 a.m. to 5 p.m. at Connelly Park, formerly Airman’s Beach.  The hydroplanes are from the golden age of hydroplane racing in the Pacific Northwest.  They are fast, loud and showy.  This is not a formal race event. It is a “test and tune” which allows much more variety in staging the boats on the water.
