BATH — Habitat for Humanity/ 7 Rivers Maine celebrated 20 years of building in the Mid-coast region with a dinner dance at the Maine Maritime Museum.

Dave Perron, the affiliate’s executive director, gave Jeff Geiger, president of Bath Iron Works, a partnership award, which Geiger accepted on behalf of all employees at the shipyard.

The award, which was an original print created by one of Habitat’s founders, Brunswick artist Judith Long, incorporated a blueprint of a Habitat home that BIW volunteers built and which had an overlay of trees and an inscription of gratitude. The event raised $15,000, all of which will go directly toward building new homes, weatherizing and repairing existing homes.

“ We thank our largest financial supporter over these 20 years and we thank all the BIW volunteers who have worked on nearly all 32 houses Habitat has built,” Perron said, according to a Habitat for Humanity release. “ We couldn’t have been as successful at providing safe, affordable, sustainable housing for Habitat families without BIW as a partner.”

The dinner-dance featured a behind-the-scenes tour of the shipyard. Devan Bailey, for whose four-person family Habitat is building a home in Topsham, gave a speech.

The band Under the Covers donated music for the occasion. Local businesses donated items for a benefit auction.
