The ship to steam at a speed of 201/2 knots for four runs on the mile
and for two hours continuously afterward. She was further to be
capable of steaming for six hours continuously at a speed of 181/2
knots, without any artificial means of producing draught. She was also
to be capable of steaming a distance of at least 5,700 knots for 500
tons of coal, at some speed over 10 knots, to be chosen by the
builders. Over the length of her machinery and magazine spaces she was
to have a sloping deck extending to 6 ft. below the water line at the
side, and formed of plates 43/4 in. thick. This deck was to extend to
about 1 ft. above the water line, and the flat part to be 3-1/8 in.
thick. Beyond the machinery and magazine spaces, the deck was to be
gradually reduced to 3 in. thick at the ends. This deck is intended to
protect the vitals of the ship, such as boilers, engines, powder
magazines, steering gear, etc., from the effects of shot and shell,

dependent upon a similar structure raised above this protective deck
to a height of about 5 ft. above the water.
This structure is covered by a water tight deck known as the main deck
of the ship, on which the cabins and living spaces are arranged.
