The Argosy Cruises Christmas Ship™ Festival is a ship-to-shore holiday celebration that has been a Northwest tradition since 1949. The Spirit of Seattle, the Official Christmas Ship™, is decorated with hundreds of shimmery white lights and sails to different Puget Sound waterfront communities – around 65 in all. Choirs on board the Christmas Ship™ perform to guests aboard as well as to our Follow Boats and to those communities gathered on shore.
