Which is better, port or starboard?
This isn’t a mistake at all, but rather an alleged error that everyone assumes to be real, whereas Cameron was spot on. The crew yells “hard to starboard” and “hard to port” as they try to escape the iceberg, and the helmsman performs the exact opposite of what he should. In 1912, however, port was considered the right side while starboard was deemed the left. After a while, this altered, but against popular opinion, Cameron got it precisely right in the film.
