Nothing is wrong with your model. The truth is, the uboat is the most horrible war machine in terms of defense and armor. Any damage in any form can be lethal!
Just because your Hull is fine does not mean your pumps, stuffing boxes, torpedo tube, etc are good. Leaks can occur in any place on that boat.
Having a stable hull only means you don’t have to worry about the ocean crushing your body with hundreds of pounds per sq inch when it collapses.
Your boat in normal operation leaks normally and is pumped out via bilge pump. You may have damage in areas where your bilge cannot keep up.
Attacking on surface is dangerous!
Hope this helps!
