It is probable, however, that the life of the ship would have been lengthened somewhat if these doors had been left open, for the water would have flowed through them to the after part of the ship, and the rate of flow of the water into the ship would have been for a time reduced as the bow might have been kept up a little by the water which flowed aft.
It is thus seen that the efficiency of the automatic arrangements for the closing of the water-tight doors, which was questioned during the inquiry, had no important bearing on the question of hastening the sinking of the ship, except that, in the case of the doors not having been closed by the engineers, it might have retarded the sinking of the ship if they had not acted. The engineers would not have prevented the doors from closing unless they had been convinced that the ship was doomed. There is no evidence that they did prevent the doors from closing.
The engineers were applying the pumps when Barrett, leading stoker, left No. 5 boiler room, but even if they had succeeded in getting all the pumps in the ship to work they could not have saved the ship or prolonged her life to any appreciable extent.
EFFECT OF SUGGESTED ADDITIONAL SUBDIVISION UPON FLOATATION.
Water-tight decks.—It is in evidence that advantage might be obtained from the point of view of greater safety in having a water-tight deck.
Without entering into the general question of the advantage of water-tight decks for all ships, it is desirable to form an opinion in the case of the Titanic as to whether making the bulkhead deck water-tight would have been an advantage in the circumstances of the accident, or in case of accident to ships of this class.
I am advised that it is found that with all the compartments certainly known to have been flooded, viz., those forward of No. 4 boiler room, the ship would have remained afloat if the bulkhead deck had been a water-tight deck. If, however, No. 4 boiler room had also been flooded the ship would not have remained afloat unless, in addition to making the bulkhead deck water-tight, the transverse bulkhead abaft of No. 4 boiler room had been carried up to D deck.
To make the bulkhead deck effectively water-tight for this purpose it would have been necessary to carry water-tight trunks round all the openings in the bulkhead deck up to C deck.
It has been shown that with the bulkhead abaft No. 5 boiler room carried to C deck the ship would have remained afloat if the compartments certainly known to have been damaged had been flooded.
I do not desire to express an opinion upon the question whether it would have conduced to safety in the case of the Titanic if a water-tight deck had been fitted below the water line, as there may be some objections to such a deck. There are many considerations involved, and I think that the matter should be dealt with by the bulkhead committee for ships in general.
