In defense of James Cameron, he did make every effort to make sure the ship’s voyage seemed realistic. However, we can also determine precisely when he was mistaken because we are aware of the Titanic’s actual course.
Jack and Rose are seen spitting over the deck at sundown, right before supper, in the well-known deck-spitting scene (did we really need that, by the way?). The fact that they are on the port side of the ship indicates that they are moving northwest, even though the ship was actually traveling southwest. Even if we realize it’s not much to get worked up over, it’s still a mistake.
