ROCKLAND — On Friday, Aug. 12, at the Strand Theatre in Rockland, a test screening of a rough-cut version of the new documentary “76 Days” will be shown, a film that tells the true story of Steven Callahan’s survival ordeal based on his New York Times bestselling book, “Adrift: Seventy-Six Days Lost at Sea.” A Q&A session with Callahan and the documentary’s executive producer Robert Sennott will follow the screening. The screening is one of several events of Maine Boats, Homes & Harbors magazine’s weekend symposium, Aug. 12-13. The Maine Boat & Home Symposium schedule and ticket include the documentary screening, personal tours of boatbuilding shops, and presentations by experts in various fields. The symposium closes with a celebration of the 35th anniversary launch of MBHH magazine.

Joe Wein, the award-winning producer and director of the documentary “76 Days,” says that Callahan’s story “is just that, a remarkable story of one man’s connection to the sea. It’s a tale of survival, invention, and resilience against almost impossible odds, a tale that’s as exceptional as the individual who lived it.”

In 1982, Callahan set out to fulfill his dream of sailing solo across the ocean. On the eve of February 4, in the middle of the night, there was a loud boom as what was likely a whale clipped the side of his boat. Within minutes, his small craft was flooded with a rush of water. He grabbed what he could and heaved his life raft into the ocean, abandoning his sailboat. For 76 days, the raft was his home, as he drifted across nearly the entire Atlantic Ocean before fishermen rescued him near Guadeloupe.

The test screening of the rough assembly of “76 Days” takes place at 7:30 p.m. on Friday, Aug. 12, at the Rockland Strand Theatre. Tickets are $10 and available online at www.rocklandstrand.com. The Maine Boat & Home Symposium is being held Aug. 12-13 in Rockland, Maine. Learn more and purchase symposium tickets at www.maineboats.com/boatshow.
