Armored belt, casemate, and spar-deck redoubt. Ram bow, round overhanging stern, single screw, full sail-power. The belt encircles the ship to the height of the main-deck beams. There is no fore-and-aft fire from the casemate, that being secured by an upper-deck redoubt mounted on the forward end of the casemate and having an overhang of about five feet. ([See Sultan’s spar-deck redoubt].) Mixed construction, the armored part of the hull being of wood and the unarmored upper works of iron.

DON JUAN. KAISER MAX. PRINZ EUGEN.

Armored belt and casemate, ram bow, round overhanging stern, single screw, full sail-power. The belt encircles the water-line to the height of the main-deck beams, coming down forward in a curve over the point of the ram. The casemate rises to the spar-deck beams. The side forward on the main-deck is recessed to open forward fire from the casemate. No after-fire from the casemate, that being secured by unprotected light stern-guns. These ships are rebuilt from broadside iron-clads.

DON JUAN.

FERDINAND MAX. HAPSBURG. SALAMANDER.

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.
