... The brigantine-rigged steam yacht Carola IV, owned by Leonard Richards, New York Yacht Club, was at Herreshoff's last Tuesday [June 1, 1915] to pick up a power launch that has just been completed. ... [Note: The referred-to launch was apparently the steam launch #313p which according to a cost estimate sheet in the Halsey C. Herreshoff Collection at the Herreshoff Marine Museum was built or delivered in 1915 (at a contract price of $4500).]" (Source: Anon. "Notes from the Week's Log." Boston Globe, June 6, 1915, p. 62.)

• Launch for L Richards (HMCo-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.

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.

"The Construction Record states this launch's contract date as April 21, 1914, with the 4 in 1914 penciled over with a question mark. Given that this launch was apparently delivered to its owner in June 1915 it is probable that the correct year of the contract was 1915." (Source: van der Linde, Claas. January 22, 2019.)
