MrLeftHand First do what Mc2 said because that is also a problem. But another problem is crew. You don't have enough crew to keep your weapons powered when firing, and that's when you aren't being shot at.
(after storage was gone)

A couple of fixes would be A: use the extra cash from Mc2s idea (+B and C) to replace as many 2 bunks as you can with quarters. B: as well as using the first method, remove some of the double shields at the ends where they aren't helping much to protect vs shots. C: do the last 2 plus replacing as much as 8 eb and/or removing a few storages. (if you can)
Hope this helped!
