8-358: Shipwreck Spar Section, Deck 11

The plan view of Deck 11 is similar to Deck 12 except the ladder is on the other side.  However, where the ceiling mesh for Deck 11 and floor of Deck 10 might be expected seems to have been removed to make way for a double-height deck.  The elevator door has been modified to be extra-large with a matching large door above where the Control door is.

Does that make sense?  A space twice as high as Deck 12 with extra big doors.
