 GEOG: The ship is supposedly caught up in a rotating current in the  Bering Sea. North of the equator, this would be moving the ship in a  counterclockwise direction, driving its right (starboard) side into  the rocky islands at the edge of the current. As shown, the ships  left (port) side is at risk, meaning that the ship is drifting in a  clockwise rotation. This would be the norm south of the equator,  where the movie was filmed.
