Right. That's virtually the same position shown at 0757Z this morning.
It was reported on CruisersForum that the boat is in fact on the beach. A life preserver was found south of that position, but Laura hasn't yet been located.
Given the ship's track with the abrupt turn to the SW before entering the Channel, I'd have to agree with the swamping theory. Swamping and, perhaps, a number of other related catastrophic events.
