The Herreshoff Fishers Island 31 (FI31) stands as one of the most refined examples of the "Owner’s Class" concept developed by the Herreshoff Manufacturing Company (HMCo) during the late 1920s. While its name suggests a smaller vessel, the "31" refers specifically to its 31-foot, 6-inch waterline length; the boat actually measures approximately 43 feet, 3 inches in overall length. Commissioned by members of the Fishers Island Yacht Club, a total of 14 hulls were produced between 1927 and 1930 (HMCo hull numbers 1076 through 1089). Designed by Nathanael G. Herreshoff at the height of his powers, the FI31 was intended to bridge the gap between a pure racing machine and a comfortable coastal cruiser, offering a level of seaworthiness that allowed these yachts to transit the often-treacherous waters of Long Island Sound and the Atlantic coast with ease. According to technical records held at the MIT Museum Herreshoff Collection, the design utilized a heavy-displacement hull with a full keel and an elegant fractional Marconi sloop rig, though some were later modified.

Sailing Performance & Handling

The sailing characteristics of the Fishers Island 31 are defined by its significant displacement of approximately 21,000 pounds and a generous lead ballast-to-displacement ratio of nearly 47%. This weight distribution results in a yacht that is exceptionally stiff and capable of carrying its canvas well into a freshening breeze. On the water, the FI31 exhibits the "Herreshoff feel"—a balanced helm that provides enough feedback to be rewarding without becoming exhausting during long beats to windward.

With a Displacement/Length (D/L) ratio of roughly 305, the FI31 is technically a heavy-displacement vessel by modern standards, yet its narrow 10-foot, 7-inch beam and refined entry allow it to slice through chop rather than pounding over it. Research from the Herreshoff Marine Museum indicates that the class was designed to be handled by a small crew or even a single owner, a departure from the larger J-Class or Universal Rule boats of the era that required professional teams. Owners often report that the boat tracks exceptionally well due to the long lateral plane of its keel, making it a reliable platform for offshore passages. While it lacks the surfing capabilities of modern light-displacement hulls, its momentum allows it to carry speed through stays and maintain a high average velocity in light-to-moderate air.

Interior Comfort & Variations

For a yacht designed in the 1920s, the Fishers Island 31 offers a surprisingly functional and sophisticated interior. The layout typically follows the classic "New England" tradition: a compact galley and navigation station flanking the companionway, followed by a main saloon with two settee berths. Forward of the mast, a separate cabin provides a double V-berth, while the head is situated to port. The use of raised paneling—often in mahogany—against white-painted bulkheads creates a sense of light and space that belies the boat's narrow beam.

While the 14 hulls were built to a strict one-design specification to ensure fair racing, minor interior variations emerged over the decades as individual boats underwent restoration. Some owners opted for a more open-plan arrangement to improve airflow, while others maintained the original enclosed cabinetry. The overhead clearance is approximately six feet in the main saloon, providing standing room for most sailors, a luxury that was not always guaranteed in "metre boats" of similar length from the same period.

The Fishers Island 31 has maintained a quiet but prestigious profile in the classic yachting community. Notable hulls such as Torch and Circe have been the subjects of extensive restorations that have graced the pages of WoodenBoat magazine and other maritime periodicals. The class is frequently a standout participant in the Herreshoff Classic Yacht Regatta held in Bristol, Rhode Island. While not a "celebrity" boat in the modern sense, the FI31 is often cited by naval architects as a masterclass in proportion, frequently appearing in academic discussions regarding the evolution of the American cruiser-racer.

Known Issues & Buyer’s Checklist

Prospective owners of a Fishers Island 31 must approach the vessel with the understanding that they are stewards of a near-century-old wooden artifact. The original construction featured double-planked cedar and mahogany over white oak frames.

  • Floor Timbers and Bolts: A primary area of concern is the connection between the lead keel and the wood floor timbers. Over time, the bronze keel bolts can cause "softening" of the surrounding oak if moisture has penetrated the wood-metal interface.
  • Deck-to-Hull Joint: Like many yachts of this vintage, the transition between the deck and the sheer strake is prone to leaking. If the original canvas-covered decks have been replaced with fiberglass or teak, it is essential to inspect the underlying sub-deck for rot.
  • Mast Step Compression: The massive downward force of the Marconi rig can lead to compression of the mast step and the structural floors. Any sign of "panting" or movement in the cabin sole under sail is a red flag.
  • Refastening History: The lifespan of bronze wood screws is long but not infinite. A buyer should verify when the hull was last refastened; boats that have not been refastened in the last 30-40 years may be nearing a structural threshold.

Community & Resources

The primary repository for technical data and historical context for the FI31 is the Herreshoff Marine Museum / America’s Cup Hall of Fame in Bristol, Rhode Island. They maintain the original offsets and construction drawings for the HMCo fleet. Additionally, the MIT Museum holds the Haffenreffer-Herreshoff Collection, which includes over 14,000 architectural plans and technical records that are invaluable for any restoration project. While there is no longer a formal "active" racing class association, the community of classic Herreshoff owners is tightly knit and centered around the annual classic yacht circuit in New England.

The Verdict

The Herreshoff Fishers Island 31 is an elite choice for the traditionalist who values pedigree, aesthetic perfection, and a "big boat" feel in a manageable 43-foot package. It is a vessel that demands significant maintenance but rewards its owner with peerless sailing dynamics and a permanent invitation to the world’s most prestigious classic regattas.

Pros

  • Exceptional balance and tracking in heavy weather.
  • Timeless aesthetic lines that define the "golden age" of yachting.
  • Manageable size for a couple or small family to cruise.
  • High investment value due to its Herreshoff pedigree.

Cons

  • High maintenance costs associated with wooden hull and brightwork.
  • Draft of 6 feet may limit access to some shallow-water gunkholes.
  • The narrow beam provides less interior volume compared to modern 40-footers.
