The Wackiest Ship in the Army

During World War II, Lieutenant Rip Crandall (Jack Lemmon), an expert yachtsman in civilian life, now based at Townsville, Queensland, Australia, is surprised to be assigned command of a sailing ship, the ''USS Echo''. The only crew member who knows how to work a ship with sails is eager young Ensign (rank)#United States Tommy Hanson (Ricky Nelson), who cost Crandall a yacht race with a mistake before the war.
