The Concordia 40—most commonly known by its precise length of 39' 10"—stands as one of the most celebrated production wooden sailboats in history. Designed in 1938 through a collaboration between C. Raymond Hunt, Waldo Howland, and Bill Harris, the model was born from a desire for a seaworthy cruiser that could hold its own in the offshore racing circuits of the mid-20th century. While the first hull was built in the United States, the vast majority of the 103-unit production run was executed by the German shipyard Abeking & Rasmussen between 1938 and 1966. This cross-continental partnership resulted in a vessel that combined American design ingenuity with legendary German craftsmanship, a legacy detailed extensively by the Concordia Company. To this day, the Concordia 40 remains a benchmark for aesthetic grace, characterized by its signature "star and moon" gold-leaf covestripe and its distinctive fractional yawl rig.

Sailing Performance & Handling

The Concordia 40 is frequently lauded for its "sea-kindliness," a term that denotes its ability to maintain a comfortable motion in rough water. The hull features a deep-V section forward, designed by C. Raymond Hunt, which allows the boat to slice through chop without the pounding typical of flatter-bottomed designs. According to editorial analysis from Sail Magazine, the boat's heavy displacement (approximately 18,000 to 19,000 lbs depending on the specific build and equipment) contributes to a stable, momentum-driven ride that is particularly effective in heavy air.

The yawl rig was chosen specifically for its versatility and balance. By adjusting the mizzen sail, helmsmen can fine-tune the boat’s weather helm, allowing it to track straight with minimal effort on the tiller. While the Concordia 40 is not a "light air flier" by modern standards due to its wetted surface area and displacement, it excels on a reach and is surprisingly nimble for a long-keel design. Owners often report that the boat "finds its groove" at about 15 knots of wind, at which point the hull heels to its secondary stability and stiffens up significantly. The tracking is exceptional, a trait attributed to its generous lateral plane, making it a favorite for long-distance passage-making where autopilot or wind-vane efficiency is paramount.

Interior Comfort & Variations

The interior of the Concordia 40 is a masterclass in traditional yacht joinery, often finished in a warm combination of knotty pine, locust, or mahogany. The layout was heavily influenced by Waldo Howland’s practical approach to offshore living. A defining feature is the "Concordia Berth"—a pipe-frame bunk with a laced canvas bottom that can be folded up against the hull during the day to create comfortable backrests for the settees. This design maximizes the use of the relatively narrow 10' 3" beam, providing ample sleeping quarters for four to six people without cluttering the main salon.

Variations across the fleet are subtle but present. While the 39' 10" hull remained constant, later models—often referred to as the Concordia 41—offered a slightly modified cabin trunk and increased displacement to accommodate more modern amenities. Some hulls were also rigged as sloops rather than yawls, though the yawl remain the iconic configuration. The galley is typically located aft near the companionway for optimal ventilation and communication with the cockpit, featuring a traditional charcoal or wood-burning stove in many original hulls, which provides both heat and a dry cabin atmosphere in damp coastal climates.

The cultural footprint of the Concordia 40 is disproportionately large compared to its production numbers. It is the subject of Waldo Howland’s two-volume memoir, A Life in Boats, which serves as a foundational text for enthusiasts of the marque. The model has also been featured in numerous documentaries and publications as the pinnacle of the "Golden Age" of wooden yachting. Classic Boat Magazine has previously explored the model's enduring appeal, noting that the Concordia Yawl is perhaps the only wooden production boat to have maintained a dedicated racing class and a high resale value for over eight decades.

Known Issues & Buyer’s Checklist

Purchasing a Concordia 40 requires a specialized understanding of wooden boat maintenance. Prospective buyers must prioritize a structural survey by a surveyor experienced in Abeking & Rasmussen construction techniques.

  1. Fastenings and Frames: The original bronze screw fastenings can suffer from "de-zincification" over many decades. It is critical to inspect for "sistering" of frames (ribs), which is often done when original steam-bent oak frames have cracked or softened near the turn of the bilge.
  2. Iron Floors: Many Concordias were built with galvanized iron floors (the structural members connecting the frames across the keel). These are prone to corrosion, which can lead to "rust bleeding" and eventual weakening of the keel-to-hull joint.
  3. Deck Leaks: The original decks were often canvas-covered wood. While many have been replaced with fiberglass or teak over plywood, any sign of moisture in the deck beams or at the cabin trunk joinery can indicate significant rot issues.
  4. Mast Step: The area under the main mast is a high-stress point. Surveyors should check for compression damage or rot in the mast step and the surrounding structural timbers.
  5. Keel Bolts: Given the age of these vessels, the condition of the keel bolts is a common concern. Owners often replace them as a preventative measure every 20-30 years to ensure the lead ballast remains securely attached to the deadwood.

Community & Resources

The Concordia community is among the most organized in the world of classic yachting. The Concordia Yacht Owners Association maintains a meticulous registry of all 103 hulls, tracking their names, owners, and restoration histories. The Concordia Company in South Dartmouth, Massachusetts, remains the primary technical resource, holding original plans and providing specialized restoration services that ensure these vessels remain on the water for future generations.

The Verdict

The Concordia 40 is a vessel for the maritime purist who values heritage and "feel" over modern volume and maintenance-free ownership. It is an investment in both history and exceptional offshore performance.

Pros:

  • Aesthetic Perfection: Widely considered one of the most beautiful yachts ever designed.
  • Superb Sea-Keeping: Balanced handling and a comfortable motion in heavy weather.
  • Craftsmanship: Built to the highest standards of the mid-20th century by Abeking & Rasmussen.
  • Community Support: Access to an elite network of owners and specialized technicians.

Cons:

  • High Maintenance: Requires a significant annual budget for wooden hull and brightwork care.
  • Limited Interior Volume: Narrow beam and traditional layout may feel cramped compared to modern 40-footers.
  • Complexity of Survey: Requires a niche expert to identify potential structural wooden boat issues.
