Typical complement: 660-858
Estimated cost, $4.388 million (£1.097 million)
Remarks:
Relative extent of belt armor, 115 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.
