“ Yet the fate of that ship and her precious freight of human life hung upon the mere chance of sighting an obstruction in time to avoid collision by a quick turn of the helm. The question of hitting or missing was one not of minutes but of seconds. A ship like this, nigh upon a thousand feet in length, makes a wide sweep in turning, even with the helm hard over. At 21 knots the Titanic covered over a third of a mile in a minute's time. Even with her engines reversed she would have surged ahead for a half mile or so before coming to a stop. ”

“ The giant steamship of to-day, as she rushes through the black night and the all-obscuring fog, represents a potential engine of destruction, for which no parallel can be found in the whole field of human activity. ”

“ Enough has been said to prove that when the naval architect undertakes to build a hull that will be proof against the blow, not merely of one but of several of these terrific weapons, he has set himself a task that may well try his ingenuity to the utmost. Protection by heavy armour is out of the question. The weight would be prohibitive and, indeed, all the side armour that he can put upon the ship is needed at the water-line and above it, as a protection against the armour-piercing, high-explosive shells of the enemy. ”

“ There is every reason to believe that the celebrated firm who built the ship, renowned the world over for the high character of their work; the powerful company whose flag she carried; aye, and even her talented designer, who was the first to pronounce the Titanic a doomed vessel and went down with the ship, were united in the belief that the size of the Titanic and her construction were such that she was unsinkable by any of the ordinary accidents to which the transatlantic liner is liable. ”

“ If, then, the shipbuilder has made such wonderful strides in the strength of his construction and in the development of engine power, is it not a strange anomaly that he should have so far failed in his attempt to provide against sinking through collision, as to be under the necessity of advertising the fact, by crowding the topmost deck with appliances for saving the lives of the passengers when the ship goes down? ”

“ A review of the progress of those constructive arts which affect the safety of human life seems to show that it needs the spur of great disasters, such as this, to concentrate the attention of the engineer and the architect upon the all-important question of safety. More important than considerations of convenience, economy, speed of construction, or even revenue-earning capacity, are those of the value and sanctity of human life. ”

“ The conditions attending the loss of the Titanic were so heartrending, and its appeal has been so world-wide, as to lead us to expect that the tragedy will be preeminently fruitful in those reforms which, as we have shown, usually follow a disaster of this magnitude. Had the ship been less notable and the toll of human life less terrible, the disaster might have failed to awaken that sense of distrust in present methods which is at the root of all thorough-going reform. ”

“ We shall reintroduce in all future passenger ships those simple and effective elements of safety—the double skin, the longitudinal bulkhead, and the watertight deck—which, were conspicuous in the Great Eastern, and which alone can render such a ship as the Titanic unsinkable. ”

“ But, perhaps, after all said and done, the greatest perils of high-speed ocean travel are to be found in that spirit of nautical sangfroid, or indifference to danger, which, as this disaster has proved, may in time begin to characterise the attitude even of so experienced a navigator as the late captain of the Titanic. ”

“ Fog, with its ever-present dangers of collision, will continue to infest the ocean highways; and always, the half-submerged derelict, a peril scarcely less than that of the iceberg, will continue to sail its uncharted course over the high seas. ”

“ A large proportion of the time and money which have been expended in the development of the instruments of naval warfare has been devoted to the design and construction of weapons, whose object is to sink the enemy by destroying the integrity of the submerged portion of the hull. Chief among these weapons are the ram, the torpedo, and the mine. There can be no question that the damage inflicted by the ram of a warship would be far greater, other things being equal, than that inflicted by the bow of a merchant ship. The ram is built especially for its purpose. ”

“ IX.⁠That the narrowing of the margin of safety in merchant ships during the past fifty years has not been due to urgent considerations of economy, is proved by the fact that shipowners have not hesitated to incur the enormous expense involved in providing the costly machinery to secure high speed, or the equally heavy outlay involved in providing the sumptuous accommodations which characterise the modern liner. ”

“ To-day, so great are the weight and engine power that the giant steamship, if the captain is willing to risk some minor mishaps to her upper works, may be driven resistlessly along the appointed lines of travel regardless of wind and sea. So far as the loss of the ship from heavy weather is concerned, man has obtained complete mastery of the ocean. ”

“ It takes a "horror"—a "holocaust" of human life, with all its attendant exploitation in the press and the monthly magazine, to awaken a busy and preoccupied world to the danger and beget those stringent laws and improved constructions which are the earmarks of progress towards an ideal civilisation. ”

“ Now, here is a practice which should be made compulsory in the construction of all passenger-carrying steamships. Only by filling a compartment with water is it possible to determine whether that compartment is watertight. To send an important ship to sea without testing her bulkheads is an invitation to disaster. The amount of water that may find its way through a newly-constructed bulkhead is something astonishing ”

“ But there are two other forms of accident on the high seas—collision with another ship and the running down of a derelict—whose possibilities of disaster are scarcely less. For if the huge steamships of our day, moving at high speed, are such potential engines of destruction, it follows that the damaging effects of collisions are proportionately increased. ”

“ Too frequently these considerations are the last to receive attention. This is due less to indifference than to inadvertence—a failure to remember that an accident which may be insignificant in its effect on steel and stone, may be fatal to frail flesh and blood. Furthermore, the monumental disasters, and particularly those occurring in this age of great constructive works, are frequently traceable to hidden or unsuspected causes, the existence and potentialities of which are revealed only when the mischief has been done. ”

“ Collision with an iceberg is one of the permanent risks of ocean travel, and this stupendous calamity has shown how disastrous its results may be. We cannot afford to gamble with chance in a hazard whose issue involves the life or death of a whole townful of people. ”

“ Other things being equal, the protection of a ship against sinking is exactly proportionate to the number of separate watertight compartments into which the interior of her hull is subdivided. If she contains no watertight partitions whatsoever, her sinking, due to damage below the water-line, is a mere matter of time. If the inflow exceeds the capacity of the pumps, water will flow into the ship until all buoyancy is lost. Protection against sinking is obtained by dividing the interior of the hull into a number of compartments by means of strong, watertight partitions, or bulkheads. ”

“ Not only is it an exceedingly stiff and strong construction; but it is so framed and tied into the bow of the warship, that it will tear open a long, gaping wound in the hull of the enemy before it is broken off or twisted out of place. The bow of the merchant vessel is a relatively frail structure, and many a ship that has been rammed has owed its salvation to the fact that immediately upon contact, the bow of the ramming ship is crumpled up or bent aside, and the depth of penetration into the vessel that is rammed is greatly limited. ”

“ The safety line represents the depth to which a ship will sink when any two adjoining compartments are opened to the sea and therefore flooded. If the two forward compartments are flooded, for instance, the bow may sink with safety, until the water is only three one-hundredths of the depth of the ship, at the side, from the bulkhead deck. If two central compartments are flooded, the ship is supposed to settle with safety until the bulkhead deck at that point is only three one-hundredths of the depth of the side, at that place, above the water. ”

“ Protracted and amazing immunity from disasters of portentous magnitude has bred in us something of that very contempt for the dangers of the sea above referred to. We have piled deck upon deck until the "floating palace" of the sea towers twice as far above the water-line as it extends below it. So rapidly have we added weight to weight and horsepower to horsepower, that both the mass and the power have been quadrupled. ”

“ The watertight subdivision of the Great Eastern was more complete than that of any ship that was ever constructed for the merchant service, more thorough even than that of recent passenger ships which have been designed for use as auxiliary cruisers in time of war. In addition to the great protection afforded by her double hull, she was subdivided by nine transverse bulkheads, which extended from the bottom clear through to the upper deck, or to a height of 30 feet above the water-line. ”

“ In regard to the provision of ample structural strength with a minimum of weight, the increase of safety by watertight subdivision and cellular double-bottom, the design of propelling machinery and boilers, with a view to economy of coal and great endurance for long-distance steaming; the selection of forms and dimensions likely to minimise resistance and favour good behaviour at sea, Brunel displayed a knowledge of principles such as no other ship designer of that time seems to have possessed. ”

“ Considerations both of humanity and self-interest should lead to the adoption of similar principles of construction by every passenger steamship company. It is possible that the time will come, and it may indeed be very close at hand, when the most attractive page in the illustrated steamship pamphlet will be one containing plans of the ships, in which the safeguards against sinking—such as side bunkers, high bulkheads, and watertight decks—are clearly delineated. ”

“ It sounds like a truism to say that a watertight bulkhead must be watertight; yet it is a fact that only in the navy are the proper precautions taken to test the bulkheads and make sure that they will not leak when they are subjected to heavy water pressure. Before a ship is accepted by the government, every compartment is tested by filling it with water and placing it under the maximum pressure to which it would be subjected if the ship were deeply submerged. ”

“ The protection afforded by the one is limited by the fallibility of human nature.
The protection afforded by the other is exact, absolutely sure, and will last as long as the ship itself.
If we would make ocean travel safe we must make the ship, as far as possible, unsinkable. In other words, the naval architect must adopt that principle of construction, common in other lines of mechanical work, which has been aptly designated as "fool-proof." ”
