The Seguin 44 CB TM represents a highwater mark of semicustom American yachting, born from a partnership between the legendary design firm Sparkman & Stephens and the master boatbuilders of LymanMorse in Thomaston, Maine. Launched in 1980, this series arrived during a transitional era when the sailboat industry was pivoting rapidly toward highvolume production models. LymanMorse, under the guidance of Cabot Lyman, resisted this generic tide, collaborating with naval architects Olin Stephens and Mitch Neff to craft a heavydisplacement ocean voyager with soul—a vessel that was exceptionally robust, elegant, and engineered to build a lifelong bond with its owner. Built in limited numbers, with only 14 to 16 hulls completed, each Seguin 44 was customized to the exact requirements of its commissioning owner, resulting in a fleet of highly individualized, heirloomquality yachts.

Design Brief & Intent

The Seguin 44 was conceived to be an uncompromising offshore passagemaker, a true go-anywhere cruiser capable of navigating deep oceans in absolute safety and comfort. It competed directly with the upper echelon of New England builders of the era, standing shoulder-to-shoulder with the likes of Hinckley, Cambria, Alden, and Little Harbor. What distinguished the Seguin from its rivals was the synthesis of classic Sparkman & Stephens lines—such as a sweet sheerline, moderate beam, and balanced overhangs—with the high-tech, rugged build philosophies of Lyman-Morse. Below the waterline, the hull features a solid fiberglass laminate designed to withstand impact, while the topsides are cored to manage overall weight distribution and insulate the living space.

Stepping below deck, the interior is a masterclass in traditional Maine craftsmanship, defined by hand-rubbed teak or mahogany joinery and impeccable cabin soles. Unlike mass-produced boats, there are no structural fiberglass liners here; instead, the wood interior is meticulously bonded to the hull, enhancing structural rigidity. The layout prioritizes security at sea, featuring a deep, L-shaped galley with high fids, a secure U-shaped salon settee, and dedicated sea berths. Every detail, from the heavy-duty portlights to the thoughtfully integrated navigation station, was engineered for crew comfort and self-reliance during weeks-long blue-water passages.

Variations & Configurations

While the standard Seguin 44 was offered with a fixed deep fin keel and a skeg-hung rudder, the centerboard variation represents a highly versatile alternative. This configuration incorporates a shallow-draft underbody featuring a heavy lead keel housing a pivoting bronze-and-fiberglass centerboard. With the board raised, the draft is restricted to just 5.25 feet, allowing the vessel to slip into shoal-draft cruising grounds like the Bahamas or the Chesapeake Bay. When the board is lowered, the draft extends to 9 feet, transforming the boat into a high-pointing, weatherly machine that claws its way upwind with minimal leeway.

The tall mast rig option is paired with the centerboard underbody to counteract the increased displacement of this configuration. Carrying a robust masthead sloop configuration, the tall mast provides a generous sail plan of 929 square feet, compared to the standard rig's 874 square feet. This added canvas is crucial for keeping the boat's moderate-to-heavy hull active and responsive in light-air conditions, ensuring that owners do not have to rely on the auxiliary engine at the first sign of a calm breeze. Additionally, some hulls in the series were built with extended overhangs at the stern, effectively stretching the length overall to nearly 46 feet to accommodate a classic counter transom, though they shared the exact same hull mold.

Sailing Performance & Handling

Under sail, the Seguin 44 CB TM behaves exactly as a Sparkman & Stephens design should: stable, predictable, and remarkably seakindly. With a displacement-to-length ratio of 331.3, this is a heavy-displacement cruiser that carries immense momentum. It does not slam or hobbyhorse when punching through a short, steep chop; instead, its fine entry and substantial displacement slice smoothly through head seas, making long offshore runs significantly less fatiguing for the crew.

The boat's comfort ratio of 39.74 places it in the top tier of comfortable bluewater cruising designs. Its slow-motion rolling behavior in rough seas reduces the physical stress on the crew, allowing them to eat, sleep, and move about the cabin safely. Hand-in-hand with this comfort is a capsize screening ratio of 1.69, which is well below the offshore limit of 2.0. This indicates an inherently safe hull form with exceptional ultimate stability and a high resistance to roll-overs in extreme weather.

With a sail-area-to-displacement ratio of 16.12, the tall mast rig gives the Seguin 44 CB TM respectable performance across all points of sail. It is not a light-air racer, but once the breeze builds past ten knots, the boat comes alive, settling onto a comfortable heel and locking onto a steady track. The combination of a heavy keel and the deep centerboard foil provides excellent lateral resistance, allowing the boat to point high and maintain a balanced, light feel at the helm even when hard-pressed.

Known Issues & Triage

Given that these boats are now entering their fifth decade, prospective buyers must look closely at age-related structural areas. The primary concern on older Seguins is the deck. Lyman-Morse typically installed teak decks over double-layered marine plywood or cored sub-decks. Over time, the thousands of screws securing the teak can allow moisture to penetrate the core, leading to delamination and soft spots around high-load hardware. Remedying a wet deck core is a labor-intensive project that often requires removing the teak, digging out the damaged wood or foam, and re-bedding the deck with fresh laminate.

The centerboard system itself requires a rigorous inspection. The pivot pin, lifting pennant, and the internal sheave system can wear over decades of use. If the board has developed slop or play within the trunk, it can result in an annoying knocking sound at anchor or under sail, and in worse cases, it can bind. Triage typically involves hauling the boat, dropping the board, and machining a new bushing for the pivot pin, as well as replacing the stainless steel lifting cable or high-modulus line.

Additionally, the mast step—which is keel-mounted—should be checked for signs of galvanic corrosion, especially where aluminum meets steel or standing water can pool.

Modernization & Upgrades

The longevity of the Seguin 44 is exemplified by the fact that many owners routinely return their vessels to Lyman-Morse for major refits. Over the past two decades, several hulls have undergone significant modernization programs. A popular performance upgrade involves replacing the original skeg-hung rudder with a custom carbon spade rudder, often designed by naval architects like Jim Taylor. This upgrade significantly improves helm responsiveness and maneuverability, reducing the boat's turning radius and making it far more agile in tight marinas.

Drivetrain overhauls are also common. The original Westerbeke or Perkins diesel engines, which typically delivered around 55 to 70 horsepower, are frequently replaced with modern Yanmar or Nanni diesels. These modern engines offer superior fuel efficiency, reduced vibration, and lower weight. Concurrently, owners are converting older lead-acid house banks to modern lithium-iron phosphate (LiFePO4) systems, allowing them to run modern high-load electronics, watermakers, and even air conditioning without relying on a noisy diesel generator.

Finally, several owners have modernized the deck layouts by eliminating the old teak overlays entirely, re-glassing the sub-decks, and applying durable non-skid coatings. This eliminates the perpetual threat of deck leaks while significantly reducing future aesthetic maintenance.

The Verdict

The Seguin 44 CB TM is a masterpiece of New England yacht building, representing a rare intersection of classic Sparkman & Stephens design, legendary Lyman-Morse construction, and genuine offshore capability. It is a sailor's sailboat—not a plastic caravan built for dockside entertaining, but a serious voyager designed to cross oceans and return its crew safely. For the buyer willing to invest in the stewardship of a semi-custom yacht, the Seguin 44 offers a level of seakindly performance, hand-crafted beauty, and build quality that modern production builders simply cannot replicate.
