There is a huge opening on the port side of the vessel. However it looks like the aftercastle, aka the captain's quarters, is still intact, and there are three layers to it still intact. There are two voids, or deep chambers used for stowage one fore and one aft, a galley, a berthing, the lower deck divided into three parts - fore, midships, and aft. And a bilge level. You can see most of this where the ship is staved in, and some of it is guessed at just by looking.
