Legend/KEY to deck plans


Unfortunately, no one knows the answer to my questions. Perhaps someone will know the answer to this question. What were the holes all over the Tank Top marked: 15 ", 18", 21 "? Were there any hatches too?

Hello Damian.
Is it possible for you to post a picture of the section in question? The Titanic is by no means a small ship and trying to find what you are referring to is like finding a needle in a haystack.

In regard to the numbers you mentioned, granted I'm going off of what you've quoted, it seems like you aren't in fact referring to "holes" per say as you are referring to a pillar which supported the transverse beams, through a set of longitudinal girders. Beneath the Lower Deck (G) there were 21 in diameter built up columns forward and 18 in aft at the ends of the ship, reduced to 16 in at extreme ends.

Hello. All my questions relate to Tank Top. I think there will be no problem finding. I care about that the most where the hull line marked "Line at tank side" runs? The "Center of shaft" line runs at the height of the propeller shaft. But "Line at tank side" seems to run lower. Where? With a double bottom?
