HMCo #965s Avocet

"... 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.

• Avocet (MIT Museum-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.

• Avocet
• 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.

"Coquina ex-Avocet #965s was owned by Halsey Herreshoff in the 1960s and moored in Marblehead when he was studying at M.I.T. In 1960, during Hurricane Donna, she broke her mooring, went on the rocks and was severely damaged, neccessitating her restoration in Bristol by Halsey Herreshoff and his father, A. Sidney deW. Herreshoff. Coquina was sold to Briggs S. Cunningham in San Diego who later donated her back to the Herreshoff Marine Museum."

"Note that Kenneth B. Upham, in his 1994 "History and Register of the S Boats" is unable to assign a HMCo hull number to Coquina. He notes her to have been from the #996 class and lists her as "Puffin" in Marblehead in 1950, having previously been part of the Sorrento fleet." (Source: van der Linde, Claas. November 15, 2008.)

"Note that another S-boat competes for hull number #965s. The Herreshoff Registry lists this boat as 9032. It's current name is Silhouette and its history can also be traced back to the 1920s. Silhouette also has a builder's plate, but it is unclear if this was supplied during its 2005/2006 restoration at IYRS. Silhouette was owned in 2013 by Millard F. Coffin and she was moored in Patten Bay, Surry, ME in the summer of 2013." (Source: van der Linde, Claas. April 1, 2015.)
