She was fitted with 16 lifeboats 30 feet long, swung on davits of the Welin double-acting type. These davits are specially designed for dealing with two, and, where necessary, three, sets of lifeboats,--i.e., 48 altogether; more than enough to have saved every soul on board on the night of the collision. She was divided into 16 compartments by 15 transverse watertight bulkheads reaching from the double bottom to the upper deck in the forward end and to the saloon deck in the after end (Fig. 2), in both cases well above the water line. Communication between the engine rooms and boiler rooms was through watertight doors, which could all be closed instantly from the captain's bridge: a single switch, controlling powerful electro-magnets, operated them. They could also be closed by hand with a lever, and in case the floor below them was flooded by accident, a float underneath the flooring shut them automatically. These compartments were so designed that if the two largest were flooded with water--a most unlikely contingency in the ordinary way--the ship would still be quite safe. Of course, more than two were flooded the night of the collision, but exactly how many is not yet thoroughly established. Her crew had a complement of 860, made up of 475 stewards, cooks, etc., 320 engineers, and 65 engaged in her navigation. The machinery and equipment of the Titanic was the finest obtainable and represented the last word in marine construction. All her structure was of steel, of a weight, size, and thickness greater than that of any ship yet known: the girders, beams, bulkheads, and floors all of exceptional strength. It would hardly seem necessary to mention this, were it not that there is an impression among a portion of the general public that the provision of Turkish baths, gymnasiums, and other so-called luxuries involved a sacrifice of some more essential things, the absence of which was responsible for the loss of so many lives. But this is quite an erroneous impression. All these things were an additional provision for the comfort and convenience of passengers, and there is no more reason why they should not be provided on these ships than in a large hotel. There were places on the Titanic's deck where more boats and rafts could have been stored without sacrificing these things. The fault lay in not providing them, not in designing the ship without places to put them. On whom the responsibility must rest for their not being provided is another matter and must be left until later.
