The Evening Star at sea.

Ocean-going freighter under the command of Captain "Harvey" Wolf Groman assisted by his Chinese servant Ming and a crew the captain is proud to call "the pick of the scum of Europe".

Known as the "ship of spies", the Evening Star has a small passenger section capable of carrying half a dozen travelers and a cargo section divided into two compartments.

On the voyage during which Maxwell Smart is a passenger, one compartment is filled with 90 tons of bananas while the other contains 3,000 monkeys, leading to concern as to what would happen if the wall between the two compartments ever broke down.
