AN UNSINKABLE TITANIC
pression of the completeness with which the interior is bulkheaded. Although the ship shown is less than one-half as long as the Titanic, she has 27 transverse bulkheads as against the 15 on the larger ship; and all but nine of these are carried clear across the ship from side to side.
Equally complete is the system of longitudinal bulkheads. Most important of these is a central bulkhead, placed on the line of the keel, and running from stem to stern. On each side of this and extending the full length of the machinery spaces, is another bulkhead, which forms the inner wall of the coal-bunkers. Forward and aft of the machinery spaces are other longitudinal bulkheads, which form the fore- and-aft walls of the handling-rooms and ammunition-rooms.
To appreciate the completeness of the subdivision, we must look at the inboard profile and note that the spaces forward and aft of the engine- and boiler-rooms are further subdivided, in horizontal planes, by several steel, watertight decks or "flats," as they are called. Including the compartments enclosed between the walls of the double hull, the whole interior
