Hey Jason,Hi Cam,
I'm not so sure. After consulting my copy of TTSM Volume 1, it does not appear that they have anything to do with the ballast, bilge pumps, or soil pipes.
Ah, thank you. I should consult my copy as well. Thanks for the tip/help!
I do not think those portholes are involved with the Ash Ejectors personally, as those were Located on E-Deck, and had a stairwell down to F-Deck, presumably for dumping the ash there?
