"[1927-09-17] Sat 17: Calm [in] a.m. Fresh to mod[erate] SSW [wind in] p.m. Mr Barklie Henry here at noon in his 32ft [#1054s Cyrilla IV] to lay up. ..." (Source: Herreshoff, Nathanael G. Diary, 1927. Manuscript (excerpts). Diary access courtesy of Halsey C. Herreshoff.)

"During these years the class that is usually spoken of as the Fishers Island thirty-one-footers was slowly developing, but as there were not many of them built at once and because there was some variation in them, I do not speak of them as a one-design class. The first of them were straight sailboats with a gaff rig but the later ones were usually auxiliary with leg-o'-mutton rig.
While these yachts were not first designed for racing they have often done well in some of the ocean races and are well-built little ships that have been particularly liked by their owners; and some were built up to about 1935." (Source: Herreshoff, L. Francis. The Wizard of Bristol. The Life and Achievements of Nathanael Greene Herreshoff, together with An Account of Some of the Yachts he Designed. New York, 1953, p. 306.)

"MANY yachtsmen will remember the advent, some fifteen or more years ago, of a one-design class of three boats --- Comet, Dolphin and Mischief, known as the Newport 29-footers --- fine, able and fast cruising sloops from the board of none other than the genius, Nathanael Herreshoff. At one time owner of Dolphin, Mr. W. Barklie Henry was highly enthusiastic over the many fine features of these craft. However, Mr. Henry thought that they might be improved upon. Whereupon he went into conference with Mr. Herreshoff, with the result that the Fisher's Island Sound One-Design Class of five boats was formed, whose plans appear on this page...." (Source: Anon. "The Fisher's Island Sound One-Design Class." Yachting, April 1928, p. 96.)

"The demand for boats that started early last spring has kept its pace during the months of July and August and many sales and charters have been reported during that period by various brokers.
The office of Sparkman & Stephens, Naval Architects and Yacht Brokers of New York and Providence, was particularly active and among the sales effected through that organization were the following: ...

"The Fishers Island Sound 31
The first keelboat class at Fishers was the graceful Herreshoff-designed and -built Fishers Island Sound 31, or FIS-31. The number refers to waterline length, considered the best indicator of a boat's speed. The class originated with a sailor at Watch Hill Yacht Club, W. Barklie Henry, which explains its name referring to local waters. In the Herreshoff yard's promotional materials, however, 'Sound' was deleted and the boats were called the 'Fishers Island One Design.' Obviously Fishers Island had a certain cachet among yachtsmen, or at least among yacht salesmen, for its name also was applied to two other boats, the Bullseye (called the 'Fishers Island Bullseye') and the Herreshoff 23 (the 'Fishers Island 23').
The FIS-31 is A. Sidney DeWolf Herreshoff's slightly larger version of one of his father's most successful pre-World War I boats, the Newport 29, one of which, the long-successful Dolphin [#727s], still sails in the Sound. Priced at $13,000 (the equivalent of about $130,000 today), the 31 was complete with everything needed to cruise, including china. By modern standards, accommodations are extremely skimpy, with only two cabins and a total of three bunks. This was a typical layout in a cruising boat of that era. The two bunks aft are for the owner's party, with their own enclosed head. Up in the bow was a tiny cabin, called the forepeak, with a single bunk and small toilet. That was the residence of the professional sailor in khaki uniform. He (it was always a he) scrubbed the decks, polished the brass, kept up the brightwork, washed the salt off all surfaces, and cooked the meals in a dark, narrow forward galley.
Beginning in 1929, six FIS-31S sailed out of Fishers Island: the Maxwell family's Kelpie [#1157s], Elisha H. Cooper's Surprise [#1156s], Arthur Whitney's Chance [#1059s], Mrs. Henry J. Fuller's Canuck [#1054s], Joseph H. Holmes's Qutee [#1154s], Pierre S. du Pont Ill's Aldebaran [#1060s], and Thomas W. Russell's Savage [#1153s] (now called Torch and on display at the Herreshoff Marine Museum). Kelpie was still raced hard after 50 years, and Surprise (renamed Patapsco) sailed around the world in the 1960s, reportedly with the loss only of a running backstay." (Source: Rousmaniere, John. Sailing at Fishers. Mystic, CT, 2004, p. 56.)

"Although the Fishers Island Yacht Club was involved with the Fishers Island 31-footers by virtue of a few of its members owning them, that class does not appear to have been Club-sponsored. One should think of the letters 'FIS' on the sails of these boats as standing for Fishers Island Sound, the body of water in which the boats usually sailed. W. Barklie Henry, of the nearby Watch Hill Yacht Club, originated the idea for such a boat and ordered the first one, Cyrilla IV [#1054s], late in 1926. Three of his friends, thinking that his idea was sound, also ordered boats for 1927 delivery. Except for two others which were built in 1929 and sold elsewhere, the four original boats had things pretty much to themselves for the first three seasons. Then, in 1930, five more boats, some owned in Fishers Island and some in Watch Hill, joined the racing. Cirrus, then Kelpie [#1157s], was the last boat of this second batch and wasn't delivered until late August. ...
The Fishers Island 31-footers, although based on the Newport 29­footers and presumed to have been basically laid down from their offsets, (a blow-up, incidentally, of those for Alerion, had some rather significant changes made from the original model. It is likely that the new profile (longer ends, deeper keel, more raking sternpost, straighter sheer) und deck line to match were established by means of a scale drawing. However, the fairing of the lines to these new end points, according to Sidney Herreshoff, was done right on the mold loft floor - full size. Sidney was a most modest man, reluctant to take complete credit for much of what he did, but he did admit (on a taped interview) that his father was in Florida for the winter while this work was going on and that he, Sidney, was in charge of executing the needed changes. I'd say he did well!" (Source: Bray, Maynard. "A Look at the Class." Woodenboat #34, May/June 1980, p. 34.)

"[Item Transcription:] Four-page advertisement brochure titled 'Herreshoff Herreshoff Fishers Island Thirty-one Footers' showing woodcut of a Fishers Island 31 with sail number FIS 1 [#1054s CYRILLA IV] on its title page. With marconi rig sail plan, deck plan, section and profile, particulars, and short description 'These boats are the result of years of careful study to develop a model which is exceptionally sturdy and seaworthy and dry in rough going, without sacrificing the element of speed which is so much to be desired in a sail boat. The forward section is sharp enough to prevent pounding under any condition, and is sufficiently flaring to prevent the boat from throwing water even when being driven hard to windward in rough weather. They are large enough to give head room and elbow room and plenty of storage space for cruising equipment and accommodation, and yet are rigged with a conservative sail plan so that one man can get the boat under way and put it up under any weather conditions without it being a hardship.
The sail plan is large enough to make the boat fast in anything above a drifting breeze, it being considered that in calm and very light airs the boats will normally be under power. If no power had been provided, the boats would have been given a little more sail, but in that case it would have been necessary to reef them in
all strong breezes. In order to prevent the necessity of reefing fine racing sails the boats are provided with a trysail about two-thirds the size of the mainsail, and a storm jib. The trysail is provided with reef points so that in case of real storm conditions it can be reefed down to a real storm sail. In a moderate breeze the boat goes very well indeed under the full trysail and storm jib, thus making it possible to sail many times in windy and rainy weather when one would not wish to expose the racing sails under adverse conditions. These storm sails are expected to provide opportunity to use the boats many times when they would otherwise be kept at their moorings.
While every care and precaution has been taken to make these boats as able, seaworthy and pleasant handling as is possible under bad weather conditions, equal provision has been made to prevent loss of speed under sail. Their performances in the New York Yacht Club runs and in the 1929 Gibson Island race have clearly demonstrated their ability.
