Occam's razor says the simplest explanation is that they hacked SH3 to "create" the "new" SH4, adding some files, eliminating some files, changing some files, and forgetting to eliminate - change some files. My guess is they edited the SH3 file for the diesels for more depth in SH4, but forgot to change the file with the crew air supply. Type VII u-boat had a smaller diameter (smaller in every dimension) than the US fleet boats, so had less freeboard and drew less water on the surface. Decks awash for Das Boot would probably be about 20 to 21 feet.
