UL 40, the unlimited light hydroplane sponsored by King and Bunnys Appliances in the Renton Highlands, is in the hunt again this year for a Seafair trophy.

Qualifying heats are today and on Sunday, with the final on Sunday. The full schedule is included here.

“I am going to be right there, right in those pits,” said King Parker of the Stan Sayres Pits on Lake Washington.

Last year, the UL 40 came in third in the final heat in a division filled with slightly heavier boats and after breaking a belt.
