Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 70,9 %
- Above water (accommodation/working, high = better): 125,3 %
Waterplane Area: 37.316 Square feet or 3.467 Square metres

Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
2K tons heavier, 2 knots slower and a 2.5' shorter main belt than my recent effort, while admitedly the Deck is ALOT heavier. It is a bit of overkill for the purposes the ship should be used for I think, and it lacks the speed to be a true Raider.
Compared to your last AC, it has 3 less guns and 2 more knots. If you're going to build a ship like this, at least have more speed.
i'm intrigued on the intended role :-\
generally i think looks a bit under gunned and deck a bit more than required - possible to add a twin 300mm and shave 20-30mm off the deck armour?
- but all depends on what you want it to do ...
