The American clipper ship was the result of an evolution which can be traced back to the swift privateers which were built during the War of 1812. In this type of vessel the shipyards of Chesapeake Bay excelled and their handiwork was known as the "Baltimore clipper," the name suggested by the old English verb which Dryden uses to describe the flight of the falcon that "clips it down the wind." The essential difference between the clipper ship and other kinds of merchant craft was that speed and not capacity became the chief consideration. This was a radical departure for large vessels, which in all maritime history had been designed with an eye to the number of tons they were able to carry. More finely molded lines had hitherto been found only in the much smaller French lugger, the Mediterranean galley, the American schooner.

To borrow the lines of these fleet and graceful models and apply them to the design of a deepwater ship was a bold conception. It was first attempted by Isaac McKim, a Baltimore merchant, who ordered his builders in 1832 to reproduce as closely as possible the superior sailing qualities of the renowned clipper brigs and schooners of their own port. The result was the Ann McKim, of nearly five hundred tons, the first Yankee clipper ship, and distinguished as such by her long, easy water-lines, low free-board, and raking stem. She was built and finished without regard to cost, copper-sheathed, the decks gleaming with brasswork and mahogany fittings. But though she was a very fast and handsome ship and the pride of her owner, the Ann McKim could stow so little cargo that shipping men regarded her as unprofitable and swore by their full-bodied vessels a few years longer.

That the Ann McKim, however, influenced the ideas of the most progressive builders is very probable, for she was later owned by the New York firm of Howland and Aspinwall, who placed an order for the first extremely sharp clipper ship of the era. This vessel, the Rainbow, was designed by John W. Griffeths, a marine architect, who was a pioneer in that he studied shipbuilding as a science instead of working by rule-of-thumb. The Rainbow, which created a sensation while on the stocks because of her concave or hollowed lines forward, which defied all tradition and practice, was launched in 1845. She was a more radical innovation than the Ann McKim but a successful one, for on her second voyage to China the Rainbow went out against the northeast monsoon in ninety-two days and came home in eighty-eight, a record which few ships were able to better. Her commander, Captain John Land, declared her to be the fastest ship in the world and there were none to dispute him.

Even the Rainbow however, was eclipsed when not long afterward Howland and Aspinwall, now converted to the clipper, ordered the Sea Witch to be built for Captain Bob Waterman. Among all the splendid skippers of the time he was the most dashing figure. About his briny memory cluster a hundred yarns, some of them true, others legendary. It has been argued that the speed of the clippers was due more to the men who commanded them than to their hulls and rigging, and to support the theory the career of Captain Bob Waterman is quoted. He was first known to fame in the old Natchez, which was not a clipper at all and was even rated as slow while carrying cotton from New Orleans to New York. But Captain Bob took this full-pooped old packet ship around the Horn and employed her in the China tea trade. The voyages which he made in her were all fast, and he crowned them with the amazing run of seventy-eight days from Canton to New York, just one day behind the swiftest clipper passage ever sailed and which he himself performed in the Sea Witch. Incredulous mariners simply could not explain this feat of the Natchez and suggested that Bob Waterman must have brought the old hooker home by some new route of his own discovery.

Captain Bob had won a reputation for discipline as the mate of a Black Ball liner, a rough school, and he was not a mild man. Ashore his personality was said to have been a most attractive one, but there is no doubt that afloat he worked the very souls out of his sailors. The rumors that he frightfully abused them were not current, however, until he took the Sea Witch and showed the world the fastest ship under canvas. Low in the water, with black hull and gilded figurehead, she seemed too small to support her prodigious cloud of sail. For her there were to be no leisurely voyages with Captain Bob Waterman on the quarter-deck. Home from Canton she sped in seventy-seven days and then in seventy-nine—records which were never surpassed.

With what consummate skill and daring this master mariner drove his ship and how the race of hardy sailors to which he belonged compared with those of other nations may be descried in the log of another of them, Captain Philip Dumaresq, homeward bound from China in 1849 in the clipper Great Britain. Three weeks out from Java Head she had overtaken and passed seven ships heading the same way, and then she began to rush by them in one gale after another. Her log records her exploits in such entries as these: "Passed a ship under double reefs, we with our royals and studdingsails set.... Passed a ship laying-to under a close-reefed maintopsail.... Split all three topsails and had to heave to.... Seven vessels in sight and we outsail all of them.... Under double-reefed topsails passed several vessels hove-to." Much the same record might be read in the log of the medium clipper Florence—and it is the same story of carrying sail superbly on a ship which had been built to stand up under it: "Passed two barks under reefed courses and close-reefed topsails standing the same way, we with royals and topgallant studding-sails," or "Passed a ship under topsails, we with our royals set." For eleven weeks "the topsail halliards were started only once, to take in a single reef for a few hours." It is not surprising, therefore, to learn that, seventeen days out from Shanghai, the Florence exchanged signals with the English ship John Hagerman, which had sailed thirteen days before her.

Two notable events in the history of the nineteenth century occurred within the same year, 1849, to open new fields of trade to the Yankee clipper. One of these was the repeal of the British Navigation Laws which had given English ships a monopoly of the trade between London and the British East Indies, and the other was the discovery of gold in California. After centuries of pomp and power, the great East India Company had been deprived of its last exclusive rights afloat in 1833. Its ponderous, frigate-built merchantmen ceased to dominate the British commerce with China and India and were sold or broken up. All British ships were now free to engage in this trade, but the spirit and customs of the old regime still strongly survived. Flying the house-flags of private owners, the East Indiamen and China tea ships were still built and manned like frigates, slow, comfortable, snugging down for the night under reduced sail. There was no competition to arouse them until the last barrier of the Navigation Laws was let down and they had to meet the Yankee clipper with the tea trade as the huge stake.

Then at last it was farewell to the gallant old Indianian and her ornate, dignified prestige. With a sigh the London Times confessed: "We must run a race with our gigantic and unshackled rival. We must set our long-practised skill, our steady industry, and our dogged determination against his youth, ingenuity, and ardor. Let our shipbuilders and employers take warning in time. There will always be an abundant supply of vessels good enough and fast enough for short voyages. But we want fast vessels for the long voyages which otherwise will fall into American hands."

Before English merchants could prepare themselves for these new conditions, the American clipper Oriental was loading in 1850 at Hong Kong with tea for the London market. Because of her reputation for speed, she received freightage of six pounds sterling per ton while British ships rode at anchor with empty holds or were glad to sail at three pounds ten per ton. Captain Theodore Palmer delivered his sixteen hundred tons of tea in the West India Docks, London, after a crack passage of ninety-one days which had never been equaled. His clipper earned $48,000, or two-thirds of what it had cost to build her. Her arrival in London created a profound impression. The port had seen nothing like her for power and speed; her skysail yards soared far above the other shipping; the cut of her snowy canvas was faultless; all clumsy, needless tophamper had been done away with; and she appeared to be the last word in design and construction, as lean and fine and spirited as a race-horse in training.

This new competition dismayed British shipping until it could rally and fight with similar weapons The technical journal, Naval Science, acknowledged that the tea trade of the London markets had passed almost out of the hands of the English ship-owner, and that British vessels, well-manned and well-found, were known to lie for weeks in the harbor of Foo-chow, waiting for a cargo and seeing American clippers come in, load, and sail immediately with full cargoes at a higher freight than they could command. Even the Government viewed the loss of trade with concern and sent admiralty draftsmen to copy the lines of the Oriental and Challenge while they were in drydock.
