I'm having way more fun than I should be searching through the
ABS Steel Vessel Rules for the string "poop".
Sample results:
- "Poop Side Plating"
- "Bridges and Poops"
- "Exposed Poop Decks"
- "Access to Midship Quarter between Poop and Bridge"
- "A bridge or poop is not regarded as enclosed unless an alternate means of access is provided for the crew from any point on the exposed portion of the uppermost continuous deck to reach the machinery space or other working spaces within these superstructures when the bulkhead openings are closed."
I even found the equation to calculate the thickness of the poop.
