Unlike most North American cities, water transportation remains important. Washington State Ferries, the largest ferry system in the United States and the third largest in the world, operates a passenger-only ferry from Colman Dock in Downtown to Vashon Island, car ferries from Colman Dock to Bainbridge Island and to Bremerton, and a car ferry from West Seattle to Vashon Island to Southworth. Seattle was once home to the "Kalakala", a streamlined art deco-style ferry that sailed from the 1930s to the 1960s.
