On August 10, 1981, 21-year-old Tammy Ennis was swimming backstroke six miles off the coast of Volusia County, Florida, when she felt a bump on her leg. She looked down and saw a shark swimming sideways beside her, nudging her thigh. She had already been swimming for hours. She had watched a friend get pulled underwater by a shark. She was sunburned, dehydrated, and alone. Yet she turned her gaze back to the sky and kept swimming, telling herself she belonged in the ocean like a fish.

A Blind Date That Went to Sea

The day before, Tammy had overslept and missed her usual Sunday softball game. When her old neighbor Randy called to invite her on a blind date sailboat trip with a friend from Embry-Riddle Aeronautical University, she agreed. She met Randy, his girlfriend Christy, and the boat’s owner, Daniel, on the beach. The four of them set out on a lightweight 17-foot catamaran—two pontoons connected by a mesh trampoline, with a 20-foot mast. They had no life jackets. Nobody thought they needed any, since they weren’t planning to go far.

About a mile offshore, they noticed one pontoon sitting low in the water. A screw cap covering a six-inch plug hole had come loose, letting water inside. Daniel sailed them back to shore, and they patched the cap with duct tape. “Back in the day, duct tape fixes everything,” Tammy recalled. They went back out.
