HMCo #273p [Launch for St. Y. Iolanda]

"July 31, 1910
Trial of Launch built for St[eam] Yacht Iolanda, Morton Plant. Launch is practically the same as one built last year [#272p Launch for St. Y. Iolanda] & tried Oct[ober] 5 [1909] [sic, note that this launch was 35ft LOA whereas the old one was listed in the Construction Record as 28ft LOA).
With 11 persons on board. Harbor course, l[igh]t NW wind, boat [blank].
[Followed by tabulated trial run data with mean speed being 16.7mph = 14.5kn with 3 persons on board, boat stripped]." (Source: Herreshoff, N. G. Handwritten note in Trials Booklet '1898 - 1909' under date of July 31, 1910. Halsey C. Herreshoff Collection at the Herreshoff Marine Museum.)

"... Ex-Commodore Morton F. Plant, of the New York Yacht Club, was at Bristol about two weeks ago, and although ostensibly his visit was to look over the new speed launch [#273p Launch for St. Y. Iolanda] building for him, a rumor started, from what was reported from Bristol as a 'trustworthy source,' that he discussed with Herreshoff plans for a new racing schooner [#706s Elena] next year. ..."

• Launch for M F Plant (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.
