The effect of a floor rising forward on turning.--In consequence of the rise of the floor in the Rodney in the direction of a buttock-line, her centre of resistance is rather aft, because of which, and her comparatively full after-body, she turns nearly as quick as the Vanguard, though her extra number of guns are at a greater distance from the centre of gravity, and therefore must retard her in coming to. Of course the greater beam of the Vanguard will increase the moment of inertia of her sides and guns over those of the Rodney, and retard her, though not to the same extent as extra guns forward and aft; the increased moment of inertia of the sides does not increase the pitch and scend, while an increased moment of inertia of the extremities would.
