I've had a bit of a technical issue which has had me beating my head against a wall for a week and change, and I'm honestly not sure where to look for an answer. See, the problem is, I'm writing an action scene on the deck of a converted cargo ship, and I realize I know almost nothing about boats.
Here's what I need: I need some sort of a room or structure or something on the deck of an old cargo ship (circa 1910), which a person could be chased into, and subsequently escape via some other means of egress to the outside than the door they entered. Preferably some sort of a hatch or something in the ceiling. I realize I'm being terribly vague here, but I speak no lie when I say I'm completely ignorant in this area, and as such, I'm quite open to suggestions.
