Broadside frigates; ram bow, round stern, single screw, full sail-power. The armor is complete from below the water-line to the spar-deck beams, coming down forward in steps, below the point of the ram, to give a heavy support and a strong junction between the wooden hull and the armor. Armored pilot-house just abaft the main-mast. There is a light armored traverse forward, forming the forward part of the spar-deck rail and protecting a bow-gun working in two large bow-ports for fore-and-aft and beam fire. The Ferdinand Max is the frigate that sank the Re d’Italia by ramming at the battle of Lissa. [Illustration: FERDINAND MAX.] MAROS. LEITHA. Single-turreted, light-draft river monitors. The freeboard is 38 inches amidships and 20 inches forward and abaft, the deck being curved fore and aft. The turret is revolved by hand, having on top of it an armored pilot-house. The weakness in the hull armor is made up by sinking the ship when going into action until only the amidship part is out of water. The bow and stern ends are completely unarmored. SPALATO (LATE DRACHE). Originally a sister-ship to the Salamander; now being rebuilt as a citadel ship on the general plan of the Inflexible, but to carry one turret armed with two 17-inch rifles.
