Belfast Harbor Fest and 2010 National Boatbuilding Challenge has music to keep the weekend-warrior boat builders motivated. This year, a Sardine Extravaganza is adding a lot to that mix on Saturday, Aug. 21.

Kickoff Concert

Harbor Fest weekend will kick off Friday, Aug. 20 with the Compass Project from 8 a.m. to 5 p.m. As far as the music goes, Friday night is the start, thanks to the Launch Party on Steamboat Landing from 6 to 11 p.m. Hosted by Marshall Wharf Brewing Co., the evening will offer hours of live music beginning 7 p.m. under the Harbor Fest tent.

The evening will offer an interesting mix, thanks to two groups from the Portland area. Spouse will bring in an indie vibe, with its bittersweet lyrics, intertwining layers of bass and guitar-driven melodies over tight, emphatic drums. Deely Stan will fill the waterfront with a world-class tribute to the music of Walter Becker and Donald Fagen, aka Steely Dan.

Cost for the Launch Party is $10. For more information, call 338-1707.

Sardine Extravaganza

Belfast Harbor Fest’s boatbuilding challenge continues all day Saturday, ending with the relay race at 4 p.m.; and the Compass Project continues from 8 a.m. to noon Sunday, Aug. 22. Saturday’s Sardine Extravaganza, a full day of raising a ruckus for herring and sardines, will begin 11 a.m.

“We have a great lineup of performers, poets and divas,” said former Belfast Poet Laureate Karin Spitfire, who organized the event with fellow poet Gary Lawless.

The entertainment will begin at noon on the Sardine Stage erected on the Belfast Common. The afternoon will include performances by the fiddling Gawler Family (1 p.m.), Anna Dembska and the Schoodic Chorus (2 p.m.), juggler Morty Hanson (3 p.m.), Camden’s Gordon Bok, singing with the January Men and Then Some (3:30 p.m.) and the Belfast Bay Fiddlers (4:30 p.m. The Sardine Extravaganza is capped by a grand march to the old Stinson factory site with the fiddlers, Chrissy Fowler, the Flashing Fish Dancers and Sardine Singers plus the Belfast Drum and Rabble Corp., known from New Year’s By the Bay.
