Male characters are forced to strip naked on the ship during a search; however, this mostly happens "off screen" and nothing revealing is shown. Sailors are seen bare chested while on deck and engaged in work.

Some scenes on the front lines of a war, however the characters usually escape unscathed. Despite being a "war film," most of the violence is fairly tame.

No profanity. But there are two analogical (not profane) uses of hell: "War is hell," and one man refers to the ship (The Caine) as "the hell of the Caine."

Many characters regularly smoke and drink. A man who is very obviously drunk and distraught appears near the end of the movie.

Many scenes do take place on the high seas in the midst of naval battles, with characters lives in danger. However, this is more implied than actually shown, as there is very little actual violence.
