The Mermaid Class occupies a foundational role in the history of Mount Desert Yacht Yard (MDYY), serving as the initial spark for E. Farnham Butler’s transition from yacht maintenance to innovative boatbuilding. Conceived in the late 1940s—with the first hull launched in 1949—the Mermaid was designed as a rugged, responsive, and aesthetically pleasing trainer for the junior sailors of the Northeast Harbor Fleet in Maine. At approximately 11 feet in length, this open-cockpit sloop was the proving ground for the strip-planking construction techniques that would later define the yard’s more famous "Controversy" and "Amphibicon" series. According to historical records maintained by the Mount Desert Yacht Yard, the boat was designed specifically to handle the brisk, often unpredictable conditions of Somes Sound, prioritizing stability and ease of righting over the pure racing metrics of its contemporaries.

Sailing Performance & Handling

The Mermaid Class is characterized by its "lively yet forgiving" nature, a byproduct of its light displacement and traditional hull form. While technical ratios like Sail Area/Displacement (SA/Disp) are typically reserved for larger cruising vessels, the Mermaid’s performance is best understood through its power-to-weight ratio; with roughly 72 square feet of sail on a narrow, 11-foot frame, the boat accelerates quickly in light Maine afternoon southerlies.

Handling is defined by a deep centerboard that provides significant lift when beating to windward, allowing the boat to point higher than many other wooden trainers of its era. Owners often report that the boat tracks exceptionally well for its size, avoiding the "skittish" behavior common in modern fiberglass dinghies. This tracking ability is a direct result of the hull’s slight rocker and the weight of its traditional wood construction, which provides enough momentum to punch through the classic "Maine chop" without losing speed. The rig is simple—a fractional sloop configuration—designed to be managed by a single adult or two junior sailors, emphasizing fundamental seamanship over complex hardware.

The Mermaid Class remains a cultural staple of the Mount Desert Island sailing community. Its most significant "media" footprint is found in the historical archives of the Northeast Harbor Fleet, where it served for decades as the standard instructional vessel for generations of sailors. While it has not been the subject of major motion pictures, it is frequently cited in regional maritime literature, such as "Traditions and Memories of American Yachting," as a prime example of the mid-century shift toward light-displacement wooden construction. The boat's enduring legacy is most visible today at the Northeast Harbor Fleet, where restored examples are still used to teach the art of wooden boat handling.

Known Issues & Buyer’s Checklist

Prospective owners of a Mermaid Class must approach the purchase with the mindset of a conservator, as most extant hulls are decades old and constructed of traditional materials.

  • Centerboard Trunk Integrity: Like many centerboarders of this vintage, the joint between the trunk and the keel is a primary site for leaks. Inspect for "weeping" or softened wood at the base of the trunk.
  • Strip-Plank Separation: The Mermaid was built using cedar strip-planking. Over time, the glue or fasteners between the strips can fail if the boat has been left out of the water and allowed to dry excessively. Look for daylight between the planks or evidence of excessive caulking.
  • Rib and Frame Cracking: Check the steam-bent oak frames for "sistering" or cracks, particularly near the turn of the bilge where stress is highest during heavy-air sailing.
  • Fastener Bleed: If the original bronze or galvanized fasteners are reaching the end of their lifespan, you may see staining or "bleeding" through the paint. This often indicates that the boat is due for a comprehensive re-fastening.

Community & Resources

The primary hub for information on the Mermaid Class is the Mount Desert Yacht Yard itself, which remains under the stewardship of the Butler family. Because these boats were largely built for a specific regional fleet, the most active community of owners is concentrated within the Northeast Harbor Fleet and the various wooden boat restoration shops surrounding Somes Sound. Technical guidance on maintaining the strip-planked hull can often be found through the broader community of the WoodenBoat School in Brooklin, Maine, which celebrates the design philosophy of Cyrus Hamlin and Farnham Butler.

The Verdict

The Mermaid Class is a "purist’s dinghy," offering a direct connection to the golden age of Maine boatbuilding and the design genius of Farnham Butler.

Pros

  • Exquisite Aesthetics: The strip-planked cedar and traditional lines turn heads in any harbor.
  • Exceptional Stability: Designed as a trainer, it is far more stable and predictable than modern racing dinghies.
  • Historical Value: Owning a Mermaid is owning a piece of the Mount Desert Yacht Yard’s foundational history.

Cons

  • High Maintenance: As a wooden vessel, it requires annual varnish, paint, and careful winter storage.
  • Weight: Heavier than fiberglass counterparts, making it more difficult to launch from a beach or transport without a dedicated trailer.
  • Niche Market: Finding a well-maintained example usually requires a search within a very specific geographic corridor in New England.
