Better possible explanation .....
There were ferocious easterly winds blowing the boat closer to the outter banks, wind pushing the counter current thats on the outer margin of the shoals/banks and the gulfstream closer to the banks .... and the boat simply wound up on the Diamond Shoals ... simply pushed and sucked there by the current and countercurrent and the wind/waves. If you've ever seen what the Diamond Shoals off of Hatteras looks like in a NE blow ... just a foaming cauldron, then thats probably the answer of why the EPIRB shut down so fast and the boat was never seen again. Those shoals off Hatteras are the Graveyard of the Atlantic because so many ships got 'sucked' onto them.
