--------------------+---------------+----------+------------------------------------------------ DUQUESNE. TOURVILLE. Iron frigates, sheathed with wood and coppered. Strengthened bows for ramming, with heavy bronze rams. Three half-turrets or platforms on each side of the spar-deck, projecting clear of the side to give clear fore-and-aft fire. Bow-gun working in a single port under the forecastle. Pilot-house and chart-room on a bridge forward of the smoke-stacks. Boats carried on a gallows-frame between the smoke-stacks. Fine lines, heavy shoulder; the bow-frames are given a flare out from the main-deck up, to give a full forecastle for working the bow-gun. Single screw, full sail-power. Gun-deck, broadside battery, fourteen 5½-inch rifles. Spar-deck battery, seven 7½-inch rifles. Bow-fire, three 7½-inch; beam-fire, nine 5½-inch (two guns can be shifted on the gun-deck, so as to give nine for a broadside), three 7½-inch; stern-fire, two 7½-inch. Two sets of engines and boilers, placed one abaft the other for protection. Between the forward turrets on the spar-deck are the wash-rooms and water-closets, giving the appearance of a fourth half-turret. Maximum speed at sea for 24 hours, 16½ knots. [Illustration: TOURVILLE.] DUGUAY TROUIN. Iron corvette, sheathed with wood and coppered. Strengthened bow for ramming, with heavy bronze ram. Four half-turrets, similar to those of the Tourville.
