el salvador castaway. real or hoax

I'm having a hard time believing this story.

Two men (one 15 yrs old) set off from Mexico 13 months ago on a fishing trip, the boat blew off course and the older man turned up in the remote Marshall Islands a few days ago.

He says his young companion died early on and he survived by catching fish and sharks with his bare hands, drinking turtle blood and his own urine when there was no rain.

Comments on blogs have mostly been that he looks quite well fed, not withered enough and he was on a fishing boat, so why was he catching fish with his bare hands.
A lot also think he ate his companion lol

There is not enough information, but there are inconsistencies in his story.
