8 x 7.6-cm
Light battery: 8 x 7.6-cm
Weight of broadside: 718 kg
2 TT, 45.0 cm (submerged)
Main belt, 18.0 cm; bow and stern, 3.0 cm
Upper belt, 5.0 cm
Armor deck, average 5.0 cm
Conning tower, 15.0 cm
Battery armor:
Main, 18.0 cm / secondary,
15.0 cm
QF, 5.0 cm / light guns, 5.0 cm shields
Maximum speed for 11713 indicated kw = 21.00 knots

Typical complement: 416-540
Estimated cost, $2.915 million (£729,000)
Remarks:
Relative extent of belt armor, 117 percent of 'typical' coverage.
Ship has slow, easy roll; a good, steady gun platform.
Good seaboat; rides out heavy weather easily.
Magazines and engineering spaces are cramped, with poor
watertight
subdivision.
Main deck secondary guns subject to being washed down
in a seaway.
Main deck QF guns subject to being washed down in a seaway.
