The Navigator

Wealthy Rollo Treadway (Buster Keaton) preposes to his neighbor across the street, Betsy O'Brien (Kathryn McGuire), and sends his servant to book passage for a honeymoon sea cruise to Honolulu. Surprised that she would reject such a wonderful guy as himself, he decides to go on the trip anyway. Because the pier number is partially covered and it is nighttime, he ends up on the wrong ship, the Navigator, which Betsy's rich father (Frederick Vroom) has just sold to a small country at war. Agents of the other small nation set the ship adrift that night. Betsy boards the ship to rescue her father, thinking he is aboard, prior to the ship being cut loose.

So McGuire and Keaton are both onboard the same ship, alone except for each other, and don't know that the other is there. How they find each other is part of the fun. How they manage to grasp the simple things like making coffee and using a can opener - with great difficulty -is a running commentary on the idle rich of the roaring 20s since these two have always had servants to do every simple task for them.

The Navigator makes the gutsy choice for its time to allow African American actors the chance to be spear-chucking cannibals since such roles normally went to white actors in black face. It's also notable that these actors were performing their own stunts like the rest of the cast with Keaton, as always, taking the biggest risks with the most physically demanding stunts.

Donald Crisp, the co-director, was hired to direct the dramatic (non-boat) scenes, and was removed when he tried to direct the boat scenes as well. Keaton took over. In the gag where McGuire tosses the portrait that ends up dangling outside Keaton's window to frighten him, the portrait of the scary man is Crisp.
