The Tartan Tock 40, an abbreviation for Tartan Offshore Cruising Ketch, is a sailboat specifically designed for extended voyages and comfortable living at sea. Synthesizing the robust build quality characteristic of Tartan Yachts with a design philosophy geared towards offshore capability, this ketch-rigged vessel quickly gained a reputation as a stable and reliable cruiser. Designed by the renowned naval architecture firm Sparkman & Stephens and built by Tartan Marine, the Tock 40 embodies the dedication to "heirloom quality" yachts that the builder is known for.

History and Design

The Tartan Tock 40, design number 2184 from Sparkman & Stephens, officially began production in 1976 and continued until 1977, with approximately 30 units built. At this time, Tartan Marine, under the leadership of Charles Britton, was committed to advancing fiberglass construction techniques, a legacy that began with the Tartan 27. The Tock 40 was conceived as a true blue water boat, emphasizing ease of handling and seaworthiness for coastal or offshore cruising. The choice of a ketch rig for the Tock 40 was a deliberate design decision, as it is generally considered easier to manage, particularly for a boat of this size, due to the smaller individual sail areas compared to a sloop rig. This rig configuration allows for a versatile sail plan, adaptable to varying wind conditions and crew capabilities.

Sailing Performance and Handling

The Tartan Tock 40, with its substantial displacement of 24,300 lbs and a waterline length of 32.33 feet, is characterized by a very high displacement-to-length ratio of approximately 718.57. This indicates a heavy-displacement vessel, designed for comfortable motion in a seaway rather than outright speed. Her sail area to displacement ratio of about 13.15 suggests she is not optimized for light-air performance; rather, she is built to carry her way through more substantial conditions. The ballast-to-displacement ratio of 0.37, with 9,000 lbs of lead ballast, contributes to a solid and stable feel, allowing her to stand up to a good breeze. The fin keel design further enhances her upwind performance and control. Owners generally describe the Tock 40 as a comfortable and forgiving boat to sail, handling well in various sea states due to her heavy displacement and ketch rig, which provides flexibility in sail reduction.

Accommodations and Layout

The interior of the Tartan Tock 40 is designed for extended cruising comfort, though specific details beyond maximum headroom are not in the structured data. However, reviews and listings indicate a spacious layout typical of offshore cruisers of her era. The Tock 40 often features a generous "aft great room," which in some configurations is noted to be quite expansive, measuring approximately 23 by 11 feet, providing a large living area. The interior typically includes a separate owner's cabin, often located forward or aft, and at least one head. Older Tartan models, including the Tock 40, are known for quality construction and materials below deck, often featuring solid wood trim and a robust finish. Some vessels may have undergone interior restorations, with upgrades such as Corian countertops. Storage is generally ample, reflecting her cruising intent. Ventilation would typically be provided by deck hatches and ports, contributing to comfort at anchor.

Owner's Perspectives

Owners of Tartan Tock 40s frequently commend the vessel's robust construction and seaworthy hull shape, highlighting its ability to handle offshore conditions with a comfortable motion. The ketch rig is often praised for its ease of handling and versatility, making the boat manageable for a variety of sailing conditions. The spacious interior, particularly the "great room," is a recurring positive point, offering ample living space for cruisers.

While Tartan Yachts generally hold a reputation for quality, some common considerations for older models, which may apply to the Tock 40, include potential issues with original deck fittings developing leaks, which might require re-bedding over time. As with any vessel of its age, a pre-purchase survey is always recommended to identify specific maintenance requirements. The active owner communities, such as the Tartan Owners Northeast (TONE) and other forums, serve as valuable resources for sharing insights and addressing common issues, underscoring the enduring appeal and loyalty among Tartan owners.
