The Strand Theatre, 345 Main St., will host a special screening of “RawFaith,” a documentary about one Maine family’s relationship with a boat, a mission and each other, Sunday, Aug. 11 at 3:30 p.m. The SeaWorthy Productions film had its premiere screening in July at the Maine International Film Festival in Waterville.

Filmed over seven years, and 10 years in the making, the story of RawFaith, a home-built galleon, begins in 1997 on the Pleasant River in Addison and ends in a 2010 storm off Nantucket. In between, the vessel had several somewhat contentious stays in Rockland Harbor.

The McKay family — George, JoAnn, Elizabeth, Aaron, Tom and Rob — made the decision to build a three-masted galleon as a way for the family to voyage and see new places. The boat needed to be handicapped-accessible to accommodate Elizabeth, who has Marfans Syndrome. This accommodation evolved into a mission to bring accessible sailing to others. George McKay and his three sons built RawFaith over four years. The vessel was 118 feet long, 26 feet wide and weighed 300 tons. After a series of adventures, shakedown cruises and challenges that included dismastings and family breakdowns, the McKay mission came to an emotional, controversial head.

The “RawFaith” production began in 2003 when Camden-based producer David Berez began filming the final phases of construction of RawFaith. He followed the ship through its launch and several adventures, before partnering with director Gregory Roscoe in 2008. Berez and Roscoe and Gregory worked closely together on the project for a number of years. The project went into post-production in 2012 with editor Daniel Quintanilla of Rockland. The unrated film features an original soundtrack written and performed by Camden composer and musician Gintare.

Tickets are $7.50, or $12.50 with a DVD copy of the feature-length documentary. For more information on all upcoming films, live concerts, HD broadcasts and events at the Strand, visit rocklandstrand.com; call 594-0070, ext. 3; or email info@rocklandstrand.com.
