Annual Milk Carton Boat Race!

Seafair Milk Carton Derby
July 14
Green Lake

Nearly one hundred boats built with milk cartons and imagination will compete for prizes on the waters of Seattle’s Green Lake. Competition is fierce in the Racing Class, but nothing but fun and laughs will be found in the Family Open Class. There are also Military/First Responder and Commercial classes. Since 1972, this quirky celebration of creativity, science and boatmanship has entertained Seattle Seafair goers on a sunny Saturday in July. You don’t have to be a sailor to have fun at this event!
There are plenty of interactive exhibit booths to visit as well as a wide variety of food vendors to choose from when you get hungry.
