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.

From the 2000 (ca.) Transcription of the HMCo Construction Record by Vermilya/Bray

Year: 1906
E/P/S: P
No.: 258
Name: Idle Hour
OA: 41' 3"

Source: Vermilya, Peter and Maynard Bray. "Transcription of the HMCo. Construction Record." Unpublished database, ca. 2000.

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.

Research Note(s)

"Idle Hour was apparently built for the auto industry pioneer Edward W. Sparrow, who had made a fortune in real estate, including northern Michigan timber and mineral lands, and was the co-founder and first president of the the Olds Motor Vehicle Company." (Source: van der Linde, Claas. March 30, 2014.)

Note: Research notes contain information about a vessel that is often random and unedited but has been deemed useful for future research.
