It is difficult at this distance of time to determine exactly what influence the Ann McKim exercised upon the science of ship-building, though from the fact that no ship had ever been built like her, it is probable that she was an object of considerable interest in the maritime world, and it is certain that during the years following her appearance a more determined effort was made in the United States to improve the model and sailing qualities of ships. Among the most notable of these attempts were the Courier, already mentioned, built by Donald McKay in 1842, and the Akbar, a ship of six hundred and fifty tons, built by Samuel Hall at East Boston in 1839, for John M. Forbes, and others, who employed her in the China trade. On her first voyage the Akbar made the passage from New York to Canton in one hundred and nine days, beating up the China Sea against the northeast monsoon. On this voyage she was commanded by Captain James Watkins, in after years commodore of the Pacific Mail Steamship Co. Later she was commanded by Captain Philip Dumaresq, who made a number of rapid passages in her to and from China. Then came the Helena, of 650 tons, built by William H. Webb in 1841. This ship was owned by N. L. and G. Griswold, and also sailed in the China trade under the command of Captain Benjamin, who made some fine passages. The Paul Jones, of 620 tons, built by Waterman & Elwell at Medford in 1842, was owned by John M. Forbes and Russell & Co., of China. She was commanded by Captain N. B. Palmer and on her first voyage in 1843 she sailed from Boston for Hong-kong, January 15th, crossed the equator 26 days out, was 54 days to the Cape of Good Hope, 88 days to Java Head, and arrived at Hong-kong 111 days from Boston. In 1848, this ship made the run from Java Head to New York in 76 days.

In 1844, A. A. Low & Brother, of New York, contracted with Brown & Bell to build the Houqua, of 706 tons, constructed for Captain N. B. Palmer. She made a number of very fast passages. On her first voyage she made the passage from New York to Java Head in 72 days, thence to Hong-kong in 12 days, total 84 days. Her best records from China were as follows: From Hong-kong, December 9, 1844, passed Java Head 15 days out, was 70 days to the Equator in the Atlantic, thence 20 days to New York, total 90 days—distance by log, 14,272 miles. December 9, 1845, sailed from Hong-kong, passed Java Head 16 days out, arrived at New York, March 10, 1846, 91 days’ passage. Under the command of Captain McKanzie, in 1850, she made the passage from Shanghai to New York in 88 days, the shortest passage up to that time. This ship was named in honor of Houqua, the well-known Canton merchant who was beloved and respected by American and English residents in China, no less for his integrity than for his great kindness and his business ability.

In 1844 also William H. Webb built the Montauk, 540 tons, for A. A. Low & Brother, and the Panama, 670 tons, for N. L. & G. Griswold, both vessels for the China trade, and Samuel Hall, of East Boston, built the barque Coquette, 420 tons, commanded by Captain Oliver Eldridge. The Coquette sailed from Boston, June 29, 1844, was 76 days to Java Head, and 99 days to Canton. She was owned by Russell & Co., of China, and made several fast passages between Calcutta and ports in China. Young James H. Perkins made a voyage to China as a passenger on board this vessel, and his famous schooner yacht Coquette, which defeated the sloop Maria in a match off Sandy Hook in 1846, was named for the clipper barque.

These were among the first clipper ships built in the United States, and while by no means extreme clippers, they were sharper and finer models than any vessels which had been constructed up to that time, and clearly indicated the dawn of a new epoch in naval architecture.

I have now brought this narrative to the opening of the clipper ship era, and have endeavored to sketch the development of the merchant marine of Great Britain and the United States from the common starting point—where the ship-builders of both countries derived their best knowledge of ship models and construction from the French—as they advanced along diverging lines under different climatic, social, and political conditions, until we now find them at points widely distant from each other—Great Britain with her stately, frigate-built Indiaman, embodying the glories of the past; the United States with her wild packet ship scending into a long, sweeping head sea, and flinging a rainbow of flying spray across her weather-bow, in which was imaged the promise of a glorious future.

In 1841, John W. Griffeths, of New York, proposed several improvements in marine architecture, which were embodied in the model of a clipper ship exhibited at the American Institute, in February of that year. Later he delivered a series of lectures on the science of ship-building, which were the first discourses upon this subject in the United States. Mr. Griffeths advocated carrying the stem forward in a curved line, thereby lengthening the bow above water; he also introduced long, hollow water-lines and a general drawing out and sharpening of the forward body, bringing the greatest breadth further aft. Another improvement which he proposed was to fine out the after body by rounding up the ends of the main transom, thus relieving the quarters and making the stern much lighter and handsomer above the water-line.

This proposed departure from old methods naturally met with much opposition, but in 1843 the firm of Howland & Aspinwall commissioned Smith & Dimon, of New York, in whose employ Mr. Griffeths had spent several years as draughtsman, to embody these experimental ideas in a ship of 750 tons named the Rainbow. This vessel, the first extreme clipper ship ever built, was therefore, the direct result of Mr. Griffeths’s efforts for improvement. Her bow with its concave water-lines and the greatest breadth at a point considerably further aft than had hitherto been regarded as practicable, was a radical departure, differing not merely in degree but in kind from any ship that preceded her. One critical observer declared that her bow had been turned “outside in,� and that her whole form was contrary to the laws of nature. The Rainbow was designed and built with great care and was not launched until January, 1845.

Mr. Griffeths relates a good story about the masting of this vessel. It appears that Mr. Aspinwall, who had an excellent idea of what a ship ought to be, had come to the conclusion that the masting of vessels was a question of no small moment in ship-building, and determined that his new ship should have the benefit of foreign aid in placing the masts. Accordingly, he informed the builders that he would obtain assistance from abroad, for their benefit as well as his own. The builders naturally paid little attention to this information. The port-captain, who was appointed to superintend the construction, was directed by Mr. Aspinwall to select the best authorities in Europe on masting ships. The European experts were written to in reference to this important matter, and after they had duly considered the principal dimensions of the vessel, the trade in which she was to be employed, etc., a spar draft and elaborate calculations were prepared and forwarded to New York.

In the meantime, the construction of the Rainbow had progressed steadily. The clamps being ready, the deck beams were placed according to the original drawings, the framing of the decks completed, hatches and mast partners framed, channels and mast-steps secured; the masts and yards were also made and the ship planked and caulked by the time the important despatches arrived. They were examined by the port-captain, Mr. Aspinwall was informed that they were all right, and the port-captain was requested to give the information to the builders, which, of course, was done. The ship, however, was finished without the slightest alteration from the original plans. Mr. Aspinwall, who never doubted that his pet project had been carefully carried out, attributed much of the success of this vessel to the placing of her masts by foreign rules.

The sharp model of the Rainbow gave rise to a great deal of discussion while she was on the stocks in course of construction. It was generally admitted by the recognized shipping authorities of South Street, that she was a handsome vessel, but whether she could be made to sail was a question on which there were varieties of opinion. She proved an excellent ship in every way and exceedingly fast. Her second voyage to China out and home, was made in six months and fourteen days, including two weeks in port discharging and loading cargo. She went out to China against the northeast monsoon in ninety-two and home in eighty-eight days, bringing the news of her own arrival at Canton. Captain John Land, her able and enthusiastic commander, declared that she was the fastest ship in the world, and this was undeniably true; finding no one to differ from him, he further gave it as his opinion that no ship could be built to outsail the Rainbow, and it is also true that very few vessels have ever broken her record. She was lost on her fifth voyage while bound from New York for Valparaiso in 1848 under command of Captain Hayes, and it was supposed that she foundered off Cape Horn.
