According to an alert sent tonight to King County Water Taxi riders, the regular West Seattle Water Taxi vessel, Spirit of Kingston, is going in for annual maintenance, so for the next two weeks or so, starting Monday, Melissa Ann will be on the West Seattle run, and Victoria Clipper III will fill in for Vashon. Side note: We talked recently with Greg Lerner of the King County Department of Transportation Marine Division, and he says construction of the two new Water Taxis is on schedule; Sally Fox, the Vashon vessel, is set for delivery first, to be followed by the West Seattle vessel, Doc Maynard.
