Watch the Poseidon Adventure, at the end when the Survivors are being helped out you can see the entrance to the fiery engine room behind Rogo, and the survivors getting out on the port side of the hull. (Which means the entrance to the engine room is facing the bow.)

But.

When they come out to the outside shot of the hull when you see Nonnie getting out, its quite clear that the side she is getting out is the starboard side of the ship (you can see the propellers)

Meaning that the entrance to the engine room is facing the stern, which is impossible!

That is a BIG continuity error!
