Normal behaviour??
I blast a lone merchant in shallow now and then but rarely any if escorted.
Tried that a few times, get my jazz blasted each time no matter what I try. Unless, I am lucky to get into position to take out the escort of course.
Once I remember trying to wait it out parked right next to the sunk ship. Two DD's had me pegged. They would circle and circle, only stopping breifly to make sure I was still there. But they could't or wouldn't go over the ship. Perhaps because something of the mast was poking out of the water. I even watched them blast a few Luftwaffe flyers down, now that was just plain insulting.
