The innuendos continue as the Carry On crew takes to the seas in the first of the historical costume parodies tackled by the team. Alas, some regulars are missing, making this one of the less memorable productions in the series. Bernard Cribbins in the lead role doesn't carry the same clout as Sid James at his distastefully smutty best, but longtime Carry On director Gerald Thomas manages to keep the fun shipshape and Bristol fashion, so it's still a must for die-hard fans.

Able seaman Poop-Decker signs up for adventure on the high seas with the wicked Captain Fearless. Those swabbing the decks include Juliet Mills, Charles Hawtrey and Donald Houston. The film was originally to be titled Up the Armada, but the British Board of Film Censors objected to such a rude title.
