He got really worried when he heard the sound of fish, shark or barracudas he supposed, eating and fighting over something big.
As the waters rose, he made a rack on top of a platform and piled two mattresses on top.
According to his interview with the Nation: "I started calling on the name of God. ... I started reminiscing on the verses I read before I slept. I read the Bible from Psalm 54 to 92. My wife had sent me the verses to read that night when she called me before I went to bed."
He survived off just one bottle of Coke, all he had to sustain him during the trauma.
Okene really thought he was going to die, he told the Nation, when he heard the sound of a boat engine and anchor dropping, but failed to get the attention of rescuers. He figured, given the size of the boat, that it would take a miracle for a diver to locate him. So he waded across the cabin, stripped the wall down to its steel body, then knocked on it with a hammer.
But "I heard them moving away. They were far away from where I was."
By the time he was saved, relatives already had been told the sailors were dead.
Okene kept faith with the psalm he recited, that promises to "give thanks in your name, Lord," at a service at his Redeemed Christian Church of God.
He was rescued by a diver who first used hot water to warm him up, then attached him to an oxygen mask. Once free of the sunken boat, he was put into a decompression chamber and then safely returned to the surface.
