In May 2005, Tom Tighe, captain of a forty-five-foot-long sailboat named the Almeisan, and his first mate, Loch Reidy, welcomed three new crewmembers for a five-day voyage from Connecticut across the blue waters of the Gulf Stream to sun-drenched Bermuda. The new crew included forty-six-year-old Kathy Gilchrist, seventy-year-old Ron Burd, and thirty-four-year-old Chris Ferrer. Although Tighe had made the trip forty-eight times, with Reidy accompanying him on twenty of those voyages, the rest of the crew had joined to learn more about offshore sailing. 

Four days into the voyage, an enormous storm struck, sweeping two of the crew into the towering sea. The remaining crewmembers managed to stay aboard the vessel as it was slowly torn apart by the rampaging ocean. Overboard! follows the simultaneous desperate struggles of both those still on the boat and those fighting for their lives in the sea. 

The Coast Guard, alerted to the Almeisan’s distress, rushed to the storm-tossed scene.
