Hemingway and Fuentes often sailed in search of worthy prey. Once, they encountered a formidable foe on a fishing trip to Cabo Blanco, Peru. Battling for more than three hours, the two men reeled in a 1,000-pound black marlin, a record Fuentes claims remains unbroken to this day. The fish is still on display in Peru. Fuentes and Hemingway had many nautical adventures together. On another occasion, the two men were docked at Cayo Paraiso, about 50 miles east of Havana, when they noticed an old man and a young boy wrestling with a large swordfish. They offered to help the fishermen but were gruffly turned down. This incident inspired Hemingway to write The Old Man and the Sea.
