"... to my young eyes at that period the faster steamers seemed more interesting, and one of them was the 'Little Sovereign,' built in 1904 for M. C. D. Borden. She was one hundred and twelve feet long and only eleven feet six inches beam, ran mostly in Long Island Sound, and made many trips between Narragansett Bay and New York. I do not remember exactly her speed but I think it was around twenty-six miles per hour, which was remarkably good for her power. She was not by any means the fastest yacht of her day, but I think I am right in saying she was one of the most efficient steamers ever built and ran during her life at more nearly her trial speed than other fast steamers.
... There were several other large commuters around New York that were credited with extremely high speed but I doubt if any of the time of 'Little Sovereign' had as high average speed, or as great day-after-day reliability. This was principally because 'Little Sovereign' 's speed came from having a proper beam length ratio and because she was of extremely light construction. It is very doubtful if there has ever been another yacht that carried her accommodations as fast with so little cost of fuel. So, altogether, including model, structural design, boiler, and engines, she was a designing triumph and I am very sorry I do not have a photograph of her for she certainly was a handsome yacht."

"The Herreshoffs have received this week an order for a high speed steam yacht that will keep the force of men at the shops busy until well into the summer. The new yacht is to be 110 feet in length over all and will have twin screws. A powerful engine is to be built for the yacht in the machine shops. The yacht is to be completed by June 1."

"The new steam yacht for Mr. M. C. D. Borden, of New York, is to be launched in about ten days. She is to be named Little Sovereign, and is expected to show a speed of 24 miles an hour. Mr. Borden was the owner of the Sovereign, a large steam yacht which he sold to the Government at the beginning of the Spanish-American war, when her name was changed to Scorpion. ... Designer N. G. Herreshoff has been confined to his home in Bristol with rheumatism for the past week, but is now improving." (Source: Young, F. H. "Rhode Island Letter." Forest and Stream, June 4, 1904, p. 468.)

"The Little Sovereign, which was launched from the Herreshoff works Tuesday [May 31, 1904], will be probably the fastest steam yacht ever turned out by the Herreshoffs. She is a twin screw craft with double boilers and was built for M. C. Borden of New York." (Source: Anon. "News and Notes of Local Interest." Bristol Phoenix, June 3, 1904, p. 2.)

"The new steam launch, Little Sovereign, which was given a satisfactory trial in the bay last Friday [June 3, 1904], was taken to Marblehead Sunday, the boat having been accepted by her owner, M. C. D. Borden of Fall River. The Little Sovereign is the fastest launch ever built at Herreshoffs and oh the speed trial she made 28 miles an hour, which is one mile above her contract speed. The new launch is 110 feet long and has boilers firing at both ends, with triple expansion engines. She is built of southern pine, with mahogany finished deck house, and is painted white above the water line and green below." (Source: Anon. "Bristol and Vicinity."

"Providence, R. I., June 4 [1904]. --- The steam yacht Little Sovereign, built by the Herreshoffs for Mr. M. C. D. Borden, of New York, was launched at Bristol this week. Her design is similar to that of Mr. August Belmont's Scout [#203p], but she is much faster than that boat. She is a little more than 100ft. in length, and has a breadth ot about 10ft., and her estimated speed is 28 miles. It is believed that she will beat Mr. H. H. Rogers' Kanawha, the first winner of the Lysistrata cup. Little Sovereign will have her trial spin over the measured mile course in lower Narragansett Bay." (Source: Young, F. H.

"Providence, R. I., June 11 [1904]. --- ... The new steam yacht, Little Sovereign, owned by Mr. M. C. D. Borden, of New York, and just launched by the Herreshoffs at Bristol, has proved on her trials to be faster than the contract called for. She will go to Marblehead this week, where her owner will place her in commission. She is fitted with twin screws, and although the engines are not remarkably powerful, she can easily steam at 23 miles an hour, being a thin, wedge-shaped craft about 110ft long and 10ft beam. The Herreshoffs have begun the construction of another new steam yacht, to be about 50ft. long and 7ft. beam. The keel has been laid and the planking commenced."

"An investigation is being conducted in the Court of General Sessions, Quebec, into a charge of an attempt to defraud the Quebec Liquor Commission and the Dominion Government by bringing in a cargo of 3,000 cases, each containing 5 gall, of alcoholic beverages. The case is of importance, not only on account of the size of the cargo, but on account of the standing of some of the persons who are alleged to be implicated in some way or other. The barge Trembly, of Quebec, was seized a few days before last Christmas by Dominion and provincial officers at St. Sulpice, Que., where she was lying, and the cargo remaining on board was placed in the Quebec Liquor Commission's charge. Those who are charged with the offence include Capt. Symons, Harbor Master, Montreal; D. J. Perrault, Assistant Harbor Master, Montreal; Capt. U. Trembly, owner and master of the seized barge; Come Dufresne, river pilot, Portneuf; J. B. E. Bissaillon, Chief of Montreal Customs Preventive Police, L. Brian, garage owner, Montreal, and M. G. Hearne, Montreal. Four United States ...
This he did, the cargo consisting of 3,000 cases of alcoholic beverages, 1,200 of which were subsequently transferred near Three Rivers to the barge St. George, and 1,000 to the United States yacht Sioux. As the remainder of the cargo was was being discharged at St. Sulpice, the seizure was made. The evidence is very intricated, in order to show the alleged connection of the differenct parties with the transaction at one step or another. The case has been before the court in various ways since Dec. 23, when the first arrests were made, and on Jan. 17 the further hearing was adjourned to Jan 24." (Source: Anon.

"Sioux
(formerly Little Sovereign)
This unusually beautiful Steam Yacht, while on the St. Lawrence River, was owned by the Bourne family, Summer residents at the famous Castle on Dark Island near Chippewa Bay, New York. As to design and type, she represented a larger version of the fast Herreshoff yachts, built in earlier years. Unlike these, however, she was powered with two engines, instead of one, which drove twin propellers. In 1907, as the Little Sovereign, the boat was owned by Mr. M. C. D. Borden of 117 Duane Street, New York City. Her Home Port and Port of Registry were then that city. In 1910, and inclusive of 1913, as the Sioux, the yacht was owned by Mr. Frederick G. Bourne of 149 Broadway, New York City. Her home Port and Port of Registry were as yet the same. We have found no ownership listing in 1920, but the Home Port and Port of Registry remained New York City. Miss Marjorie Bourne of 149 Broadway, New York City owned the boat in 1923. The Home Port remained New York City, but the Port of Registry had been changed to Ogdensburg, New York.
The Sioux (as the Little Sovereign) was designed by Mr. Nathaniel G. Herreshoff and built by the Herreshoff Manufacturing Company at Bristol, Rhode Island in 1904. Construction was of wood. Her specifications were as follow: Net Tons, 37; Gross Tons, 55; Overall Length, 111' 10"; Waterline Length, 102' 3"; Beam, 11' 6"; Depth, 5' 10"; Draft, 3' 11". Her powerplant was two 3-Cylinder Triple Expansion Steam Engines, 6 1/4", 10" and 16" of bore and 9" of stroke. They were supplied by one Water Tube Boiler. The engines and boiler were constructed at the Herreshoff plant. It would seem that the yacht should have attained a speed of about 15 M.P.H.
We do not know when the Sioux left the River. In 1929, her ownership was listed in the name of Mr. Oliver P. Martin of New York City. Both the Home Port and Port of Registry were again New York City. Her Registration Number was always 200952. References:

• Little Sovereign (HMCo-made index card)
• Little Sovereign (MIT Museum-made index card)
• Note: The vessel index cards comprise two sets of a total of some 3200 cards about vessels built by HMCo, with dimensions and information regarding drawings, later or former vessel names, and owners. They were compiled from HMCo's early days until 1920 and added to in later decades, apparently by Hart Nautical curator William A. Baker and his successors. While HMCo seems to have used only one set of index cards, all sorted by name and, where no name was available, by number, later users at MIT apparently divided them into two sets of cards, one sorted by vessel name, the other by vessel number and greatly expanded the number of cards. Original HMCo cards are usually lined and almost always punched with a hole at bottom center while later cards usually have no hole, are unlined, and often carry substantially less information. All cards are held by the Francis Russell Hart Nautical Collections of the MIT Museum in Cambridge, Mass.
