Yes, it's quite possible the inverted ship was acting like a diving
bell and the water level inside the hull was below the water level in
the harbor outside. Opening a hole in the hull would then release air
which had been forcing the interior water level down. But the water
levels would then equalize, the hull would not fill with water and
water would not then flow out of the hole.

Wasn't the superstructure resting on the bottom, anyway?
