Doctors say the Salvadoran fisherman who apparently drifted at sea for more than a year is vowing never to return to the ocean and even plans to avoid the beach.

Fredy Sermeno, head of psychiatry at the San Rafael hospital, said sailor Jose Salvador Alvarenga doesn't have any serious mental problems, but "what has stayed with him is fear of the sea, he doesn't want to know anything about the sea. He wants to avoid, in any way possible, being in front of the sea."

Alvarenga, 37, underwent a battery of tests after returning home from the Marshall Islands, where he showed up after what he has described as 6,500-mile (10,500-kilometer) journey from Mexico that began when his small fishing boat was thrown off course by bad weather.
