Yes, I meant to say damage to both trim AND ballast tanks. Edited above for clarity. Also, I need to reemphasize that (at least in my case), NO hull damage was reported. I had assumed that the "hull damaged" reports referred to the pressure hull. It would be very interesting to hear if anyone has experienced uncontrolled sinking on an even keel with no hull damaged reports or bulkhead damage/flooding in the DC screen. That would suggest that both fore and aft bouyancy was compromised at the same time. So far I've only experienced and seen reported loss of buoyancy aft, suggesting that rear ballast/trim tanks were destroyed.
The behavior I have observed and seen reported would seem to suggest there is a simple division into fore and aft trim/ballast tanks, if that is the actual cause. No one has reported rolling to the port or starboard, so I wouldn't think damage to either side is tracked separately.
