For modeling purposes and ignoring the ballast tanks, think of the pressure hull as a steel cylinder full of air. It will have a different bulk density than the surrounding water.
Given the ballast tanks are either side of the hull, can you ignore them? It is going to a long thin anomaly. Most of what follk see as submarine is casing, the actual boat is quite a bit smaller. Things have obviously moved on since I tried to measure G.
