Since 1972, this quirky celebration of creativity and boatmanship features nearly 100 colorful milk carton boats of all shapes and design. Children, adults, families and businesses are all invited to build milk carton watercraft and compete on the waters of Green Lake for prizes and bragging rights.
You don’t have to be a sailor to have fun at this event! Participants and spectators can visit interactive exhibit booths, satisfy hunger with food vendors, meet Seafair personalities and more! Your Seattle Seafair Pirates will be there cheering on the participants and enjoying the festivities with the crowds!
