The Lady Slipper is a 12-foot, 4-inch rowing and sailing craft that serves as a refined expression of the Edey & Duff philosophy: translating the elegance of 19th-century wooden workboats into high-quality, low-maintenance fiberglass. Designed by company co-founder Peter Duff, the Lady Slipper is modeled after the classic "Whitehall" pulling boats, which were historically prized for their tracking and efficiency in the harbors of New York and Boston. While many of the builder’s other small craft, such as the Lyle Hess-designed Fatty Knees, were optimized for buoyancy and load-carrying as tenders, the Lady Slipper was conceived primarily as a "pulling boat"—a vessel dedicated to the joy of rowing for exercise and light-air sailing. Its hull features a lean, narrow beam of approximately 4 feet and a distinctive wineglass transom, allowing it to glide through the water with minimal resistance and a remarkably clean wake.

Sailing Performance & Handling
Under sail, the Lady Slipper is a spirited and sensitive performer, though its narrow hull prioritizes speed over the initial stability found in wider-beamed daysailers. It typically utilizes a simple, high-aspect ratio rig—often a balanced lug or a standing lug—which allows for quick setup and easy reefing. Because the boat lacks a heavy keel, it relies on a pivoting centerboard for upwind tracking and the weight of the crew for stability. In a detailed review by Small Boats Monthly, the design is noted for its ability to carry its way between strokes when rowing, a characteristic that translates well to sailing in light winds where momentum is key.
The boat’s handling is characterized by its "sweet" helm and responsiveness. With a displacement of roughly 120 pounds (hull weight), it is exceptionally light, meaning even a small gust is immediately converted into forward motion. However, this light weight and narrow waterline require an attentive sailor; it is a "lively" boat that provides immediate feedback, making it an excellent trainer for those looking to master the nuances of sail trim and weight distribution. When the wind dies, the boat transitions seamlessly back to its primary role as a premier rowing craft, often equipped with traditional wooden oars and bronze oarlocks.
Popular Mentions & Media
The Lady Slipper has maintained a quiet but prestigious reputation within the small-boat community, frequently appearing in the pages of WoodenBoat Magazine and its sister publications as a benchmark for fiberglass interpretations of traditional designs. It is often cited in discussions regarding "exercise rowing" due to its ability to be fitted with a sliding seat or traditional fixed thwarts. While it has not been the subject of major motion pictures, its cultural footprint is firmly established among "messing about in boats" enthusiasts who value the aesthetic of a wooden boat without the exhaustive maintenance schedule of a cedar-on-oak hull.
Known Issues & Buyer’s Checklist
When inspecting a pre-owned Lady Slipper, the primary focus should be on the integrity of the wood-to-fiberglass joins and the condition of the sailing hardware.
- Wood Trim and Gunwales: Edey & Duff utilized significant amounts of teak or mahogany for the rails, thwarts, and transoms to maintain the classic aesthetic. Check for "graying" or soft spots, particularly where the gunwales are through-bolted to the fiberglass hull, as moisture can become trapped in these interfaces.
- Centerboard Trunk: Inspect the trunk for vertical cracks or leaks. Since these boats are often beach-launched or trailered, the trunk can suffer stress if the board is struck while moving at speed.
- Gelcoat Crazing: Like many boats from the 1970s and 80s, the Lady Slipper may exhibit spiderweb cracks in the gelcoat, particularly around the mast step and the rowing stations where the stress of the oars is concentrated.
- Mast Step Integrity: Ensure the mast partner (the support where the mast passes through the thwart) and the step on the floor are solid. Years of sailing in heavy air can put significant leverage on these points, potentially loosening the fasteners.
Community & Resources
Owners of the Lady Slipper often find camaraderie through broader traditional small craft associations rather than a model-specific club. The Traditional Small Craft Association (TSCA) is a primary resource for technical advice and regional "raids" or meet-ups where Lady Slippers are frequent participants. Additionally, because production of several Edey & Duff designs transitioned to Ballentine’s Boat Shop after the original yard closed, they remains a vital resource for parts, restoration, and historical information regarding the builder’s small-boat fleet.
The Verdict
The Lady Slipper is a specialized craft for the sailor who views time on the water as a form of art and exercise. It is less a utilitarian "utility" boat and more a refined "rowing machine" that happens to sail beautifully.
Pros:
- Exquisite traditional lines that stand out in any harbor.
- Exceptional rowing efficiency and tracking.
- Lightweight enough for easy trailering or roof-topping on larger vehicles.
- High-quality Edey & Duff construction ensures long-term hull durability.
Cons:
- Narrow beam makes it more "tender" (tippy) than modern wide-bottom dinghies.
- Limited carrying capacity; best suited for one or two adults.
- Requires regular varnish work to maintain the extensive wood trim.
