Hang on, the Master at Arm's office was on the starboard side, right? And it had a porthole. But this map places the office almost amidships.
Which makes it all the more confusing, when you consider the path she took. I will try to draw these out. Thanks Tim!I think James Cameron put it on the port side. I'm basing that on Lovejoy watching the bullet rolling off the desk, the bullet would be rolling forward as the ship sank and the porthole is to the left of the direction that it was rolling. I don't know which side the Olympic had it when it was in an exterior cabin when it entered service in real life.
