15. Steven Callahan
Inventor and naval architect Steve Callahan was attempting a transatlantic crossing when his boat was struck by a large, unknown object in the night, possibly a whale. Consequently, his vessel sank but he managed to secure a life raft and some essential equipment. He then survived at sea for 76 days by distilling sea water with a solar-powered still and hunting fish with a spear gun. Exhausted but basically unharmed, he was eventually picked up by fishermen.
14. Matthew Bryce
Matthew Bryce was surfing at Machrihanish beach, near Campbeltown in Scotland, when he was suddenly swept 13 miles out to sea. The 22-year-old spent the next 32 hours drifting in chilly open waters. However, he survived the ordeal thanks to his protective wetsuit and his surfboard, which he used as a buoyancy aid. Nevertheless, Bryce was suffering from hypothermia by the time a helicopter from the Belfast Coastguard located him.
