AS often as the “record is broken,” and the Atlantic voyage is reduced by some unprecedentedly fast passage, we may be sure that there is a flutter in the offices of the rival lines which have thus been left behind. Between the Cunard, the Guion, the Inman, and the White Star lines there has been a constant race for supremacy, now one, and then the other, taking the first place. No ship has been allowed to keep the lead for more than a year or two. When sixteen knots have been developed by one line, seventeen knots have been aimed at by another, and the ship of that speed is no longer a wonder. So when we read in the newspapers of the “fastest passage” we may take it for granted that it is no sooner heard of in Liverpool than the managers of the lines momentarily surpassed are preparing to beat it. If the triumph belongs to the Cunard line, at the very next meeting of the directors of the White Star and Inman lines it will be discussed, and though an order for another ship may not be given there and then, it is sure to follow.
An order for a new ship of the class required to compete in the modern passenger service of the Atlantic is not by any means a matter to be determined on without grave consideration. Speed is costly, and as you increase it it is generally necessary to also increase the tonnage. Thus if the problem before you is to beat the record of a seven-thousand-ton ship, which has developed eighteen knots with engines of twelve thousand five hundred horse-power, you must (principally for economic reasons) have a larger hull as well as more powerful engines for your competing vessel. This forces upon your consideration tides, channels, harbor-bars, and dock accommodations, all of which impose limitations upon you. And then the cost of the ship herself is not a matter which even the wealthiest of corporations can provide for at a moment’s notice: it is not one hundred thousand dollars, or five hundred thousand dollars that the work calls for, but about five times the latter sum, for it is safe to say that a vessel superior to the City of New York or the Etruria could not be built for less than two million and a half of dollars.
The “financing” of such an undertaking requires time: there are long consultations between the directors, bankers, and ship-builders. If we could follow the steps of the gentleman to whom these negotiations are intrusted, we might see him flying off from Liverpool for Euston: closeted in a private office down in Lombard Street or Cornhill with some capitalists who are expected to contribute to the necessary funds; again, after dinner, engaged in argument with these same capitalists in a West End mansion to which they have adjourned, and then racing off in the precarious hansom cab to catch the night train from King’s Cross for Glasgow.
Sometimes the ship-builders are willing to become part owners of the projected vessel; sometimes they take as part payment for the work some older vessels of the line, which they refit, re-engine, modernize, and sell again. The ability of the builders to make an arrangement of this kind, of course, influences the placing of the contract, in a measure, but they must also be able to give certain guarantees. They must enter into an engagement that the projected ship shall be able to carry so many passengers and so many tons of cargo, and to attain a specified speed on a given consumption of coal per day. Let us say, for instance, that the stipulations are these: Accommodations for 600 saloon passengers, 150 intermediate passengers, and 1,500 steerage passengers; registered tonnage, 6,000, speed, 19 knots on a consumption of 300 tons per day. If the ship fails to fulfil these conditions the builders agree to forfeit a part of the amount they would otherwise receive for her, or they may be compelled to take her back altogether. This was the case with the City of Rome, which was built for the Inman line by the Barrow Ship-building Company. A beautiful ship in every way; of exquisite model; fitted with a degree of luxury unsurpassed at the time she was launched, she proved to have neither the speed nor the carrying capacity which had been guaranteed, and the Inman line refused to accept her. In a very few instances only are such guarantees omitted from the contract.
Now, ship-building is not an exact science, and the closest calculations are often upset in the result by unforeseen and inexplicable causes. It can never be said with absolute certainty just what speed a ship will attain, or exactly what quantity of cargo she will carry. The most ingenious and patient of experiments have not yet succeeded in eliminating the mysterious variability of result which the ship-builder finds, however closely he repeats his well-defined formulas. Two ships, like the Umbria and the Etruria, may be built side by side, of identical materials, lines, and dimensions; engines, boilers, and propellers may be the same, yet one will turn out to be a knot or two faster than the other, and neither the designer nor the builder is able to say why.
It is apparent, then, that in guaranteeing an exceptionally high rate of speed the builder assumes no little risk. The designing of a fast ship is indeed more of an art than a science, and each designer proceeds on a theory more or less his own. If the reader has an opportunity to compare models of the Servia, the Alaska, and the City of Rome, three ships built at the same time, each intended to rival the others, he will see by the varying proportions of length or breadth, and by other contrasts, how the opinions of the architects have differed as to the best lines for obtaining speed. True, it is not possible to ignore formulas altogether, but the designer’s intuitions or inspirations are not less serviceable to him than his technical knowledge.
