The Star Legend passenger ship went through the Ballard Locks today to get to Lake Union from Puget Sound. News reports said it was the biggest vessel yet – but that must be by tonnage*. The Star Legend’s beam is 67.5 ft (20.6 m), and the lock is 80 ft wide (24.4 m), so there was room to work with.
*In 1975, on-lookers beheld the extraordinary sight of a wide floating dry-dock vessel 81 ft wide (24.7 m), that was manoeuvred through by listing the vessel on her side, here.
