Argosy’s Christmas Ship “Spirit of Seattle,” accompanied by a flotilla of decorated boats, will grace Eagle Harbor from 6-8 p.m. Monday, Dec. 13.

Gather at Waterfront Park to hear SoundWave, Bainbridge Island’s a cappella singing group, sing holiday favorites, including Winter Wonderland, Silver Bells, and Rockin’ Around the Christmas Tree. The group, which currently includes five female and four male singers, has performed since 2002 at public and private functions on Bainbridge Island and around Kitsap County.

The ship’s 60,000-watt sound system will fill Eagle Harbor with SoundWave’s a cappella harmonies between 7:30 and 7:50 p.m.

Concert goers can enjoy holiday music and caroling, free cocoa and hot cider. Candles will be provided.

If you have a boat and want to join in with some holiday spirit, contact Eagle Harbor Marina or Bainbridge Island Yacht Club at 842-4003.

SoundWave will also perform several numbers as a part of the Evergreen Singers concert at 1:30 p.m. Monday in the Commons.
