Sail a Crooked Ship

In this comedy caper based on a novel by Nathaniel Benchley, a gang of crooks begin exploiting an innocent ex-Navy officer who, wanting to impress his employer's daughter, is sailing a fleet of ramshackle scows. One of the crooks cons the fellow into believing he is a shipwright. The thief then plots to use the vessel for a bank robbery. The hero is then forced to sail the ship himself after he and his girlfriend are captured. Meanwhile another villain tries to commandeer the vessel, but the officer is able to signal the Coast Guard by using his girl friend's bra as a slingshot.
