Can each turret pivot/elevate or are they fixed in place?
Most guns are fixed in place and the captain steers the ship in order to aim them. This greatly simplifies the coordination needed and is generally considered the best approach. Some battleships have rotating and/or elevating guns depending on the preference of the captain. I have used both and find rotating guns useful in some situations, like shooting a ship that is caught along shore, but generally they require more room in the boat and require more time to keep them working properly.
