The Sakonnet OD, frequently referred to as the Sakonnet 23, is widely considered one of the finest "modern classic" daysailers produced in the last three decades. Designed by the legendary naval architect Joel White of Brooklin Boat Yard, the vessel was born from a desire to create a simple, elegant craft that offered high performance without the maintenance burden of a traditional wooden hull. Originally commissioned as a oneoff coldmolded prototype named LaLa, the design's success led to production in fiberglass by the renowned yard Edey & Duff in Mattapoisett, Massachusetts. In 2010, the molds and building rights were acquired by Marshall Marine Corporation, which continues to produce the vessel to contemporary standards. The hull is a doubleended design, echoing the grace of the Herreshoff era while utilizing a modern foamcored fiberglass layup for stiffness and a highaspect rig for speed.

Sailing Performance & Handling

The Sakonnet OD is often described as a "thoroughbred" because of its sensitive, responsive nature on the helm. With a Displacement-Length (D/L) ratio of approximately 137, the boat sits firmly in the "light racer" category, allowing it to accelerate quickly in light air and maintain momentum through tacks. According to technical assessments by Sail Magazine, the boat was designed to reach its hull speed with minimal effort, a feat aided by its narrow 6' 1" beam and clean, double-ended exit.

Despite its light displacement of 2,000 lbs, the Sakonnet 23 is remarkably stable. It features a ballast ratio of 55%, which is significantly higher than most daysailers in its class. This stability is derived from a 920-lb lead bulb keel combined with a ballasted pivoting centerboard. This configuration allows for a dual-purpose sailing profile: with the board down, the boat draws 5' 2" and points exceptionally high upwind; with the board up, the draft is reduced to just 1' 10", making it an ideal choice for gunkholing or beaching. The use of a tapered aluminum mast and a modern fractional rig ensures that the center of effort remains low, reducing heeling even when pushed in a stiff breeze.

The Sakonnet 23 holds a distinguished place in maritime literature and design history. Its creation is frequently cited in discussions of Joel White’s legacy as a designer who successfully bridged the gap between the aesthetic of the "Gold Age" of sail and modern materials. In an editorial for Maine Boats, Homes & Harbors, the design's artistic eye was compared to that of Nathanael Herreshoff, noting that the Sakonnet’s double-ended hull is both an "unusual surprise" and "extremely beautiful." The boat has also gained a cultural following among enthusiasts of Joel White’s larger designs, such as the Center Harbor 31, who see the Sakonnet as the ultimate "harbor-racing" equivalent.

Known Issues & Buyer’s Checklist

While the Sakonnet 23 is prized for its build quality, there are several model-specific areas that prospective buyers should investigate.

  • Non-Self-Draining Cockpit: One of the most critical design compromises is that the cockpit is not self-draining. Owners report that heavy rain or shipping water in a sea state requires the use of a high-capacity manual or electric bilge pump. Buyers should check the condition and wiring of the flush-mounted bilge pump and ensure the cockpit liners are free of debris.
  • Outboard Bracket Stability: Many Sakonnets were fitted with side-mounted outboard brackets. These can be prone to stress on the transom or coaming if used with motors heavier than the recommended lightweight 2hp or 3hp units. Inspect the mounting area for fiberglass stress cracks or "spidering."
  • Teak and Mahogany Maintenance: While the boat is fiberglass, it features extensive brightwork, including the tiller, floorboards, and coamings. Some boats were finished with teak oil while others were heavily varnished; buyers should look for greyed wood or peeling varnish that could indicate water ingress into the wood grain.
  • Foam Core Integrity: The hull and deck are foam-cored for stiffness and positive flotation. While Edey & Duff’s construction was robust, any improperly installed aftermarket hardware (such as cleats or instruments) can allow water to seep into the core. A moisture meter survey of the deck and around the mast step is advised.

Community & Resources

The Sakonnet OD benefits from a small but dedicated community of owners, many of whom are centered around New England and the Chesapeake Bay. Technical support and original design insights are still available through the Brooklin Boat Yard, where the original plans are archived. For those looking for new builds, replacement parts, or official class specifications, the Marshall Marine Corporation serves as the primary technical authority and current manufacturer.

The Verdict

The Sakonnet 23 is an exquisite choice for the sailor who prioritizes aesthetics and performance over overnight accommodations. It is a pure sailor’s boat, rewarding a nuanced touch with exceptional speed and grace.

Pros:

  • Exceptional aesthetic appeal with classic double-ended lines.
  • Highly stable and safe due to a 55% ballast ratio.
  • Shoal-draft capability (1' 10") allows for beaching and easy trailering.
  • Sensitive handling that makes it a competitive one-design racer.

Cons:

  • Cockpit is not self-draining, requiring diligent bailing or pumping.
  • Minimal weather protection; it is an open boat with no cabin.
  • Maintenance-heavy brightwork compared to more utilitarian daysailers.
