Create a depressing scene inside a passage with a small square peephole and barred door.

The mizzenmast fills so much of this space that passage around it involves a good squeeze to port or starboard. Overhead, the signs of water damage are evident on the planks where they butt the mast. What little light drifts through that space gets lost before it reaches the deck. On the port side of the passage, next to a ladder, stands a barred door with a small square peephole.
