Every week at Lake Union Park

• 7:00 PM

  Chantey Sing aboard the Arthur Foss (recurring)

  Monthly on a Friday, 7:00 – 9:00 PM · music · maritime · free

  A monthly maritime song circle aboard the tugboat Arthur Foss at the Historic Ships Wharf, hosted by Northwest Seaport. Northwest Seaport moves the sing to other moorages some months, and the September 18 date sails from Corinthian Yacht Club in Shilshole rather than Lake Union, so it is not listed here. Check the organizer's page before you go.
