Highly recommend this one!
" Don’t miss the boat at Seattle’s largest maritime industry celebration! It’s the Vigor Seattle Maritime Festival, sponsored by the Seattle Propeller Club with the Port of Seattle.
Free family fun includes WorkBoat Parade, Lake Union/Ship Canal Tours presented by the Port of Seattle, Workboat World Invitational Boat Building Competition, Fireboat Display, Tugboat Demonstration and Ballet, Abandon Ship Demonstration, Coast Guard Sea-Air Rescue Demonstration, historic, government and workboat tours, Survival Suit Races, free kids boating building by The Center for Wooden Boats, fun bounces, face painting, displays, music and food!
Please note that due to significant construction on the Seawall and Tunnel projects, all Family Fun Day activities will shift to South Lake Union. The move forces the cancellation of this year’s tugboat race and chowder cook-off. However, a spectacular WorkBoat Parade and our usual popular maritime activities should attract thousands to South Lake Union. "
