This sketch (titled "The Stoke Hole") was drawn in 1883 when the Square Box Boilers were being replaced. It shows one of the locally made Cylindrical Boilers being installed in the single boiler room. The boiler room took up the Hold & Lower Decks as far as height was concerned.
8 mouseovers. men, top 2 cylinders in boiler, floor & dots.
Below the floor of the Hold Deck was a compartment that could be filled with water (474 tons) so as to lower the profile of the ship.
