"[1925-06-07] Sun 7: [Thermometer] 89 [to] 60 [degrees]. Still hot, but in p.m. wind changed to NE and made a great change. ... Took sail in S boat [probably one of the new Bar Harbor Class S-boats #909s-#913s] with Ann in p.m. ...
[1925-06-10] Wed 10: Strong SSW [wind]. T&L early, fog most of day, ch[anging] to NW by sunset. 5 S class boats [#909s-#913s] left for Bar Harbor." (Source: Herreshoff, Nathanael G. Diary, 1925. Manuscript (excerpts). Diary access courtesy of Halsey C. Herreshoff.)

"... 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.

"1925. ... Herreshoff's had all the firm could handle. By the end of March the seven [sic, i.e. five?] S boats for Bar Harbor [#909s Mab, #910s Albatross, #911s Elinor, #912s Emily II, #913s Spray] were nearly finished, they were building two of the Herreshoff 15-footers to be used at Newport [probably #997s Nabob II and #998s Nancy]; the Alden designed S boat [#931s Nassau] for a Chicago yachtsman was planked and ready to be turned over and set on her keel; twelve 14-foot sailing skiffs [#924s-#929s, #935s-#938s, #946s, #947s, #950s, #951s], the same as N. G. Herreshoff had taken to Florida the year before but with centerboards instead of fin keels, had been shipped to the Biscayne Bay Yacht Club, and they had orders for two 50-foot auxiliary schooners, Harlequin [#934s] and Rofa [#933s], for New Bedford men. ..."
