"... in some ways the most interesting product of 1919 was the one-design class of 'S' boats, which came out early that spring.
While there were few of them built the first year, perhaps twenty, the company continued building them off and on for the next eight or nine years so that eventually there were perhaps a hundred and fifty or more of them, and besides being good little cruisers they have furnished active racing up to the present time in widely separated districts. If I remember right these little yachts cost less than two thousand dollars the first few years, so they have been a good investment for some owners for they were built well enough to last for years if handled carefully. Perhaps the 'S' boats would even have been more popular if they had been a little better looking but that defect should not be wholly blamed on Captain Nat for it was the request of the original sponsors of the class that they have short overhangs and full bows and sterns. This feature has made them rather queer-looking Universal Rule boats, and consequently they are not particularly fast for their rating. But there have been few all-around better boats for afternoon sailing, cruising, and racing, and perhaps also the last one-design class that was somewhat comfortable." (Source: Herreshoff, L. Francis. The Wizard of Bristol. The Life and Achievements of Nathanael Greene Herreshoff, together with An Account of Some of the Yachts he Designed. New York, 1953, p. 306.)

"A new class of small racing sloops are under construction at Herreshoffs for Marblehead, New York and Philadelphia yachtsmen. These boats are designed to the rating rating rule, and on a 20.6-foot water line will rate in class S.
Although the little racers will be given 'Marconi' rigs, their hulls will be more along the lines of the larger rating craft turned out at the Bristol Yard, high sided, with short ends. It is expected that the boats will all be completed for delivery to the owners in May.
So far more than a dozen yachtsmen have placed their orders, and it is expected that fully a score of the boats will be built. Among the yachtsmen of Marblehead who will have boats in the class are Frank B. Crowninshield [#837s Doodah subsequently owned by Lincoln Davis, Jr.], Robert A. Leeson [#834s Widgeon], Nathaniel F. Ayer [#828s Gob], Chester L. Dane [#835s Kajee?], Louis K. Liggett [#845s Swallow], Guy Lowell [#849s Cima], Charles J. W. Foster [#832s Woodchuck], Lawrence F. Percival [#833s Cheerio] and Daniel W. Lawrence [#831s Papoose]." (Source: Anon. "Yachts and Yachtsmen." Boston Globe, January 11, 1920, p. 44.)

"... Probably the first of the new 'S' sloops from designs of Herreshoff will be given a trial the last of next month. Nine of these little racers are being built for yachtsmen of Marblehead. ... [The first S-boat to be trialled was apparently #828s Gob.]" (Source: Anon. "Notes from the Week's Log." Boston Globe, January 25, 1920, p. 55.)

"Tuesday [March 16, 1920] at Bristol the first of the fleet of new 'S' sloops, ordered by New York and Marblehead yachtsmen was given a trial in Bristol Harbor. It was the first spin of a new yacht off Bristol this year, indicating that Spring is surely on its way.
Beating up the wind, the little racer, not much over 20 feet in length, looked really handsome. Manager Robert W. Emmons 2d of Resolute, Manager George Nichols of the Vanitie and Charles Francis Adams handled the unnamed knockabout in the 18-knot breeze on this first trial.
The yacht, which has a truck cabin and short overhangs, sailed like a witch, and was at her best with her 'Marconi' rig when close hauled. A number of these one-designed knockabouts are ready for launching at Herreshoffs." (Source: Anon. "Yachts and Yachtsmen." Boston Globe, March 21, 1920, p. 54.)

"... The 'S' class sloops, 20 feet on the waterline, are being put overboard at Herreshoff's, as 14 of these little racers [apparently #828s Gob, #830s Spinster, #831s Papoose, #832s Woodchuck, #833s Cheerio, #834s Widgeon, #835s Kajee, #836s Daphnia, #837s Doodah, #838s Teaticket, #844s Vant, #845s Swallow, #846s Fano, and #849s Cima] are finished. Several of the boats with their 'Marconi' rigs were launched last Tuesday [March 23, 1920] and Wednesday, and are ready for trial spins. They were built in the same shed where the celebrated aeroplane hull of the trans-Atlantic NC-4 [#341p Sea Plane Hull] was constructed for the Government about two years ago. ..." (Source: Anon. "Notes from the Week's Log." Boston Globe, March 28, 1920, p. 53.)

"... There are now only three of three S class Marconi rigged racing sloops at Herreshoff's, the rest having been taken to Marblehead for racing this Summer. ..." (Source: Anon. "Notes from the Week's Log." Boston Globe, June 20, 1920, p. 51.)

"A new fleet of one-design racing yachts that will measure in Class S has been built by the Herreshoff Manufacturing Company at Bristol, and as everything that comes from that plant in the shape of a vessel is designed by Captain Nat. Herreshoff, these small craft may be considered the latest type evolved by the designer and builder of cup defenders.
Fifteen of these boats are to be built, at least fourteen have been promised by the opening of the racing season, and if the fifteenth can be squeezed in, so much the better. Other boats have been ordered and will be built later. Of the boats promised ten are for members of the Eastern Y. C. and the others are for members of the Seawanhaka-Corinthian Y. C. The fifteenth boat has been ordered by Commodore Ralph N. Ellis. The others are for H. S. Whiton, Paul Hammond, and O. G. Jennings. These yachts are of the trunk-cabin type and differ from the Victory Class in that these yachts have raised decks. The Herreshoff boats cost $2,700 each. They will spread 450 square feet of canvas. While they form a one-design class, the fleet is not large enough to make a special class, and so they will sail in the regular S Class and compete against yachts turned out by other designers. Unfortunately there are no new yachts in this class, but there is still time to have some built, should any yachtsman like to pit the skill of another designer against Herreshoff. These yachts will doubtless meet the Victory yachts, which are somewhat larger, and the meeting will be watched with interest.
The general dimensions are:
Length o. a. 27.5 feet
Length w. l. 20.5 [feet]
Breadth 7 [feet]
Draught 4.75 [feet]." (Source: Anon. "New Fleet of S Class Yachts." Rudder, April 1920, p. 36.)

"... The majority of the new one-designed class & 'Marconi' rigged knockabouts for members of the Eastern Yacht Club, which were built by Herreshoff, will be at Marblehead in time for the opening race of the season. ..." (Source: Anon. "Notes from the Week's Log." Boston Globe, June 13, 1920, p. 52.)

"... This year the [Herreshoff] plant is very busy. Not only has the Resolute been overhauled, fitted with new spars and commissioned there, which in itself is a big task, but many other power and sailing craft have been built. It is a long time since Herreshoflf's was so busy and much of this success must be credited to A. Loring Swasey, who is the vice-president of the company. Mr. Swasey is not only a designer of repute but he is a practical constructor of considerable experience and a very capable business manager. This Spring Captain Nat. Herreshoff has been far from well. He contracted a heavy cold on his return from Bermuda and at one time pneumonia was feared. James Swan is the Superintendent of the plant. He is one of the most capable steel constructors in the country and the work now in progress in the shops shows his skill. ...
A fleet of small sloops to measure in Class S have been built. Eleven of these are for members of the Eastern Y. C. and others are for members of the Seawanhaka-Corinthian and New Haven Yacht Clubs. These boats are different in model from Herreshoff's recent yachts, and when afloat they very much resemble the famous Cock Robin except that the new boats have Marconi masts of considerable but not excessive lengths. Some of these boats have been tried and showed up well. A picture herewith shows one under sail. There is going to be much friendly rivalry between the owners of these S yachts and the owners of the Victory Class. The Victory yachts rate about a foot more than the Herreshoff boats, measuring 17.93 feet while the S boats rate under 17 feet. One Victory yacht is being built at Graves Yard at Marblehead and is fitted with a curved Marconi spar. Her owner is very keen about meeting the S boats during the season. ..." (Source: Anon. "Yacht Building Yards Very Busy. Many New Vessels at Herreshoffs." Rudder, June 1920, p. 14)

"This season will be the third that the one-designed Herreshoff class 'S' knockabouts have been raced at Marblehead, and while a number of the original owners continue to be interested in the class, there have been a number of changes in the personal of the Corinthians sailing these yachts since last year.
Early last fall the Gob [#828s] was sold by Nathaniel F. Ayer to a Portland yachtsman, thus taking that yacht away from local water. In addition, neither the Doodah [#837s], owned by Lincoln and Benjamin Davis, nor the Kajee [#835s], owned by Chester L. Dane and Charles W. Jaynes, will be raced this Summer if the present plans of the owners are carried out.
To partly counteract the loss of these three yachts to the class, the Uncas[#???], purchased this spring by Gifford K. Simonds of the Corinthian and Eastern Yacht Club, has been added to the racing fleet. This knockabout was at Marblehead all of last season but was never raced or even under sail throughout the 1921 season. The Uncas probably will be handled in in the racing for Mr. Simonds by 'Bill' Brown of Marblehead, who is well known along the North Shore as a very clever skipper." (Source: Anon. "Yachts and Yachtsmen." Boston Globe, June 18, 1922, p. 55.)

"... It is reported that the Herreshoff one-design 'S' knockabout Gob recently sold by E. H. Randall of Portland to a New York yachtsman sank in the Cape Cod Canal while making the trip from Portland to Long Island Sound waters. ...[Note: There has been discussion if this boat was Gob or some other, as yet unidentified S-class. See the Steve Nagy Herreshoff Registry under the boat name of Boblink or Red Snapper.]" (Source: Anon. "Notes From The Week's Log." Boston Globe, September 3, 1922, p. 57.)

"... A change in ownership of two of the S class sloops of the Seawanhaka Corinthian Yacht Club fleet was also reported yesterday. The sloop [#858s] Meg was sold by Irving Cox to Stuart Peck, and [#828s] Sister was sold by W. F. Carey to Henry W. Warner. Both Mr. Cox and Mr. Carey are building in the new Seawanhaka schooner class. ..." (Source: Anon. [Title?] Newspaper?, 1923 or 1924, p. xxx. [This paper counld not be identified anymore.

• Gob (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.

• Note: The L. Francis Herreshoff index cards comprise a set of some 1200 cards about vessels built by HMCo, with dimensions and / or ownership information. Apparently compiled in the early 1930s, for later HMCo-built boats like the Fishers Island 23s or the Northeast Harbor 30s are not included. Added to in later decades, apparently by L. F. Herreshoff as well as his long-time secretary Muriel Vaughn and others. Also 46 cards of L. F. Herreshoff-designed vessels. The original set of index cards is held by the Herreshoff Marine Museum and permission to display is gratefully acknowledged.

Note: The transcription of the HMCo Construction Record by Peter Vermilya and Maynard Bray was performed independently (and earlier) than that by Claas van der Linde. A comparison of the two transcriptions can be particularly useful in those many cases where the handwriting in the Construction Record is difficult to decipher.

"As far as Gob. Yes, I believe without doubt that Aquila is #828. When she was rebuilt by George Zachorne he found lining off marks, which look like they were used to make templates/molds. She also has a one piece keelson. The only S boat to have one to my knowledge. And the documented history seems ironclad to me." (Source: Upham, Kenneth B. Private Email to Claas van der Linde.
