Tartan 31 Information, Review, Specs

Sailing Performance & Handling

The Tartan 31 is widely regarded for its balance and stiffness, characteristics driven by its moderate displacement and a well-proportioned fractional rig. With a Sail Area/Displacement (SA/D) ratio typically hovering around 18.5, the boat is sufficiently powered to perform in light air while remaining stable when the breeze freshens. Unlike many of its contemporaries that utilized masthead rigs, the Tartan 31’s fractional setup allows for easier mainsail depowering through backstay tension, making it a favorite for short-handed sailors.

Handling is defined by a deep, balanced spade rudder that provides immediate feedback and exceptional maneuverability in tight quarters. Owners often report that the boat tracks exceptionally well for its size, a trait attributed to the hull's fine entry and the design of its keel. The model was offered with two primary keel configurations: a deep fin for maximum lift and a Scheel Keel design. The Scheel Keel was a proprietary shallow-draft solution that maintained a low center of gravity by concentrating lead weight in a flared "bulb" at the bottom, allowing the boat to navigate thinner waters without sacrificing the "stiff" sailing qualities Tartan is known for.

Interior Comfort & Variations

The interior of the Tartan 31 was a departure from the "pilot berth" era, opting instead for a layout that prioritized privacy and ergonomic flow. The most significant advancement for a boat of this length was the inclusion of a dedicated aft cabin, featuring a double berth and a hanging locker. This was made possible by the boat’s nearly 11-foot beam and the use of a T-shaped cockpit that opened up volume beneath the seats.

The main salon is traditional yet functional, featuring a U-shaped galley to starboard and a navigation station to port. Hand-oiled teak joinery, a hallmark of the Tartan brand, is used extensively, providing a warm, high-end feel that contrasts with the "liner-heavy" interiors of mass-production competitors. The V-berth forward is spacious enough for two adults, and the head is located aft of the V-berth on the port side.

In 1992, the model was superseded by the Tartan 312. While the 312 shared the same hull, it featured a more modern "swim platform" transom and moved the head aft to the starboard side. This variation allowed for a larger forward cabin area but changed the workflow of the galley. Prospective buyers should note that the original Tartan 31 remains popular for those who prefer a more centralized weight distribution and the classic "T-shaped" cockpit layout.

Known Issues & Buyer’s Checklist

• Deck Core Integrity: Like many boats of this vintage, the Tartan 31 utilizes a balsa-cored deck. Buyers should pay close attention to areas around the chainplates, stanchion bases, and the mast step. Moisture intrusion in these areas can lead to delamination and structural softening.
• Chainplate Attachments: The chainplates on the 31 are bolted to robust bulkheads, but the seals where they pass through the deck are prone to leaking if not re-bedded every few years. Persistent leaks can lead to bulkhead rot, which is a significant repair.
• Rudder Post Bearings: The balanced spade rudder exerts significant leverage on the rudder post. Over time, the bearings can wear, leading to a "thumping" sensation or excessive play in the wheel.
• Engine Mounts and Alignment: Many 31s were equipped with the Universal M-25XP diesel engine. While the engine itself is reliable, the original factory mounts are known to settle, leading to vibration and shaft misalignment. Checking the condition of the "Western" style mounts is a priority during a pre-purchase survey.

Community & Resources

The Tartan 31 benefits from an exceptionally active and technically proficient owner base. The Tartan Owners Northeast (TONE) association serves as a primary hub for technical documentation, including original wiring diagrams and plumbing schematics. Additionally, the Chesapeake Bay Tartan Sailing Club provides a regional network for owners to share maintenance tips and participate in model-specific rallies.

The Verdict

The Tartan 31 is an ideal choice for the sailor who desires a high-quality, American-built cruiser that does not compromise on sailing pedigree. While it may require more maintenance regarding its exterior teak and deck seals than a more modern "plastic" boat, its performance on the water and "heirloom" build quality remain superior to many contemporary alternatives.

Pros:

• Excellent performance-to-comfort ratio with a highly responsive helm.
• The Scheel Keel option allows for shallow water cruising without a major loss in stability.
• High-quality interior joinery that holds its value better than mass-market competitors.

Cons:

• Balsa-cored decks require vigilant maintenance to prevent expensive moisture damage.
• The aft cabin, while innovative for its time, can feel cramped for taller adults.
• Access to the stuffing box and the rear of the engine can be tight due to the interior cabinetry.
