Why wing turrets became a difficult compromise

How serious is it if a battleship's main turrets move with heavy rolling in a storm?

It is highly undesirable: heavy off-centre turret weight worsens roll, while centreline placement better supports stability and firing.

Wing turrets can make sense in some earlier design contexts, but become increasingly problematic as turret and armour weight grows. Concentrating that mass on the centreline helps reduce rolling and avoids the stresses of firing heavy guns across a ship's own deck. An apparently visual layout choice therefore affects stability, hull strength, and practical gunnery.
