Freight from Baltimore(1938)

Sabine Heitmann, the young boss for the shipping company Heitmann, has become friends with Michael, the First Officer and Helmsman of the ship, the "Sabine Heitmann". He only knows Sabine by her first name and doesn't know that she's the boss. When he discovers the fact, however, he gets pissed and refuses to accept his promotion to Captain. Then the shipping company gets a lucrative offer: In a competition with another shipping company, they need to reach Baltimore in 18 days and pick up some freight. Whoever can move their rear ends faster, gets the very profitable contract from an American firm (correct me if I'm wrong, but didn't this sort of thing sink the Titanic?). Together with Michael, Sabine comes up with a plan, which should have them win the contest. The upshot? She wins back his heart and he becomes Captain.
