Tartan 37 Information, Review, Specs

Sailing Performance & Handling

The sailing characteristics of the Tartan 37 reflect a "middle-of-the-road" philosophy that rewards the cruising sailor with predictable, linear handling. With a Displacement-to-Length ratio (D/L) of approximately 285, the vessel is firmly in the moderate-heavy displacement category, providing a comfortable motion in a seaway that lighter modern production boats often lack. According to editorial analysis from Cruising World, the boat is particularly noted for its ability to track straight, reducing helm fatigue during long offshore passages.

The Sail Area-to-Displacement (SA/D) ratio of roughly 16.5 suggests a boat that requires a breeze to truly come alive, yet it remains stiff enough to carry full sail longer than its contemporaries. In heavy air, the Sparkman & Stephens pedigree becomes evident; the boat heels to a certain point and then "locks in," showing remarkable stability. Owners frequently report that the keel-centerboard version suffers very little leeway loss compared to the deep-fin model when the board is fully deployed, though the deep-fin version remains the preferred choice for dedicated club racing.

Interior Comfort & Variations

The interior of the Tartan 37 is a masterclass in traditional yacht joinery, utilizing extensive teak and high-quality laminates that have aged remarkably well. The layout is a classic offshore arrangement: a forward V-berth followed by a head to port and hanging lockers to starboard. The main salon features a U-shaped settee that converts to a double berth, with a pilot berth often situated above the starboard settee in earlier models.

Significant variations occurred throughout the production run. Early hulls (pre-1981) often featured a more "wood-centric" interior with darker teak, while later models transitioned to a lighter, more open feel with improved ventilation through additional opening ports. The galley is located aft to starboard, designed in a U-shape to provide security for the cook while at sea, a feature frequently praised in historical reviews by Sail Magazine. A notable sibling variant is the Tartan 37-2, designed by Tim Jackett in the late 1980s; while it shares the name, it is a completely different hull and deck design, emphasizing a more modern, Euro-style interior and a faster, flatter hull form.

Popular Mentions & Media

The Tartan 37 has maintained a high profile in the cruising community, largely due to its endorsement by renowned delivery skipper and author John Kretschmer. In his various writings on used boat buying, Kretschmer has frequently cited the Tartan 37 as one of the best "off-the-shelf" boats for serious offshore work, noting its robust build and balanced helm. The model's cultural footprint is further cemented by its frequent appearances in "top 10" lists for used cruising sailboats intended for circumnavigation.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Tartan 37 with a focus on its age-related structural integrity, specifically regarding its balsa-cored components.

• Deck Delamination: Like many boats of this era, the Tartan 37 uses a balsa-cored deck. Moisture ingress around stanchion bases, chainplates, and the mast collar can lead to soft spots and core rot. A thorough percussion test or moisture meter reading is essential.
• Centerboard Mechanism: For the keel-centerboard models, the stainless steel wire pennant, sheaves, and the pivot pin are wear items. It is common for the pennant to fray over time or for the board to "clunk" if the bushings are worn.
• Mast Step Corrosion: The aluminum mast sits on a steel or cast-iron step. Over decades, the combination of saltwater and dissimilar metals can lead to galvanic corrosion at the base of the spar.
• Engine Serviceability: Many original units were fitted with Westerbeke 40 or 50 diesel engines. While reliable, parts for older models are becoming increasingly expensive and difficult to source. Check the heat exchanger and exhaust elbow for clogging or pinhole leaks.

Community & Resources

The Tartan 37 enjoys one of the most robust owner support networks in the sailing world. The Tartan 37 Sailing Association serves as a primary hub for technical data, archival brochures, and modification guides. Additionally, regional groups such as the Chesapeake Bay Tartan Sailing Club provide a wealth of "tribal knowledge" regarding the specific maintenance needs of the Sparkman & Stephens hulls.

The Verdict

The Tartan 37 is a quintessential "sailor's boat" that balances aesthetic beauty with proven offshore capability. It remains a top choice for those who value structural integrity and traditional design over the voluminous, apartment-like interiors of modern coastal cruisers.

Pros

• Exceptional Sparkman & Stephens design with timeless lines.
• Keel-centerboard option allows for versatile cruising in shallow areas.
• High-quality interior joinery that is rarely matched by modern mass-production builders.
• Predictable, sea-kindly motion in heavy weather.

Cons

• Potential for costly deck core repairs if maintenance was neglected.
• Aging engine systems may require significant investment or replacement.
• Small cockpit by modern standards, which can feel cramped with more than four adults.
