HMS canopus Canopus Class.  Distinguishable from earlier British battleships by the two centre-line funnels instead of the side by side arrangement of previous ships., this being the result of the using water tube boilers.  The class were not given the usual copper sheathing to the hull in order to save weight and provide a shallower draught as it was felt that the good docking facilities in Hong Kong would ensure that fouling (marine growth on the hull) would not be a major problem.

Comments:
Designed as smaller, cheaper and faster equivalents of the Majestic class primarily for service in the Far East.  They were the first British battleships to be fitted with Krupps type armour which allowed a reduction in thickness of armour.  Water tube boilers were introduced in this class which was one of the reasons enabling the increase in speed.  Crew 682.

HMS Canopus with pre-war funnel bands.  At the time of design there was concern that French battleships would start mounting howitzers and so were fitted with two above water armoured decks, a feature that repeated in subsequent designs until after World War 1.  Despite the introduction of Krupp armour protection was generally inferior to the Majestic class although considered adequate for their designed role.
