Adrift: 76 Days Lost at Sea by Steven Callahan

When Callahan's small sloop sank west of the Canary Islands, he found himself adrift in the Atlantic in a five-foot raft, with only enough food and water for 18 days. For 76 days he drifted 1800 miles, the only man in history to survive more than a month alone at sea in an inflatable raft. (910.4 CALLAHAN)
