Battle Barge (Shore Bombarder)

Based on a mix between coastal monitors and coastal defense ships. Both of which were designed to traverse shallow water and either be a towable battery or engage larger enemy ships from waters they couldn't enter. This takes the idea to the extreme as its meant to be towed or move under its own power to extremely shallow water (minimum of 5 meters deep and still operate as a bombardment tool. The key to this is it's extremely wide beam of 47 meters and catamaran design.
Armed with eight 12in twin turrets these ships are able to produce a withering amount of fire on any shore or inland target.
