Ok. The ship did not have a wreck. NO wreckage found. No sign of anything floating. Weather condition not too rough. Nothing to be found. Like he was devoured by a tsunami or somthing. Let's dismiss alien abduction also!
Logical deduction: Did he really sail? Possible still on land? Are we searching land? Guess not.
I am sure, the loaded MS guys can ask the coastguard for a sub to go under and search the area!
But I'm still on the idea that he did not sail.
good point and merited too..........
