Very impressed with your ship build. As you collect scraps, keep a tiny bit of everything onboard to use as a repair kit. Then a tiny bit of food/water for the crew. Repair hull at sea, if it'll let you, before collecting scraps, so the flooding won't use up your hull space. The armour on the deck/hull worked great! Yeah, I'm not sure about batteries. Maybe the fans keep them charged. Thats about all your missing I think. Looking forward to seeing you on the high seas!
