"Also in 1899, the Buzzards Bay Fifteen Footers started, first with an order of seven, but augmented to seventeen. This class has been added to for thirty-one years, so there have been about eighty built." (Source: Herreshoff, N. G. "Some of the Boats I Have Sailed In." Written 1934. In: Pinheiro, Carlton J.

Supplement
From the 1920 and earlier HMCo Index Cards at the MIT Museum
- 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.

From the 1930s L. Francis Herreshoff Index Cards at the Herreshoff Marine Museum
- 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.

Research Note(s)
"Newport 15s were the same as Buzzards Bay 15s, except for a keel that had been deepened by 6 inches for a draft of 2' 9" with centerboard up." (Source: Nagy, Steve. June 1, 2008.)
"Dimensions LOA 24ft 6in, beam 6ft 9in and draft 2ft 9in were not stated in the Construction Record but taken from data for other Newport 15s, because the Record stated that this boat was a Newport 15." (Source: van der Linde, Claas. April 8, 2015.)
Note: Research notes contain information about a vessel that is often random and unedited but has been deemed useful for future research.
