We have, I suppose, nearly reached the maximum of speed attainable by steam; have we nearly reached the maximum attainable by sails? By no means. When Anacharsis the younger was asked which was the best ship, he said the ship that had arrived safe in port; but even the ancients were not always infallible. The 'Resolution' did not prove she was the best ship by coming into port; on the contrary, she would have proved herself a much better ship if she had been able to continue her voyage. What we want in a man-of-war, as far as I understand the common-sense view of the question, is buoyancy, speed, handiness, and the power of keeping the seas for long periods. Racing cutters of 150 to 170 tons are now built to sail at a speed that two years ago was not dreamt of. Where a short time since the best of them used to take minutes to go about, they now go about in as many seconds. The racing vessels of the present day will reach thirteen or fourteen knots an hour, and sail ten knots on a wind; with hardly any wind at all they creep along eight knots. They do not appear to be able to go less than eight knots; double their size, and their speed would be immensely increased. Now if thirteen and fourteen knots can be got out of a vessel of 170 tons, and seventeen knots out of one double her size, what speed might you fairly expect to get out of a racing vessel of 10,000 tons? Rather a startling suggestion certainly; but, if carefully examined, not without reason. We have nothing to guide us as to the probable speed of a racing vessel of that size. Time allowance becomes lost in the immensity of the question.
