The Dufour T7 is a distinctive and compact sailboat, designed to offer a unique blend of trailerability and cruising capability within its modest footprint. With a length overall of just under 22 feet and a beam of 8.17 feet, she was conceived as a "trailersailer," her "T" denoting trailerability and "7" referencing her length in meters. Known for her innovative design and surprising interior volume for her size, the T7 carved out a niche as a versatile weekender and coastal cruiser. She was designed by the French naval architect Jean-Louis Noir, and built by the renowned Dufour Yachts.

The Dufour T7 was introduced in 1980, with production continuing until 1983. During this era, Dufour Yachts, founded by Michel Dufour, was a pioneer in fiberglass boatbuilding, known for creating high-quality, ready-to-sail production boats using this revolutionary material. The company's commitment to robust construction saw hulls, particularly those under 50 feet, typically built of solid fiberglass, a manufacturing ethos that applied to the T7. Jean-Louis Noir's design philosophy for the T7 emphasized innovative concepts, challenging traditional yacht design by aiming for simple operation and an easier sailing experience. Early examples of the T7 were even used in the demanding Mini Transat race, serving to validate the concept and demonstrate her capabilities. A particularly unique feature of the T7 is its manually adjustable jibing centerboard, fitted on later hulls, which was part of an innovative "auto-align system." The T7 was also available with a masthead rig, offering rigging versatility. While all models featured a central cockpit, the interior layout underwent several changes during its production run.
Sailing Performance and Handling
Despite her compact size, the Dufour T7 is noted for her lively sailing characteristics. With a reported sail area of 237 square feet and a displacement of 2,360 pounds, she is described by owners as "slippery as an eel" and an "overgrown performance sailing dinghy." This translates to a boat capable of delivering surprising performance, particularly in lighter winds, where she has been known to "embarrass bigger yachts." Her design, featuring a lifting wing keel, allows for a maximum draft of 4.5 feet for performance, which can be reduced to a shallow 1.0 foot, making her highly adaptable for shoal waters and trailering. The T7 boasts a theoretical hull speed of approximately 6.03 knots. Owners frequently praise her balance and responsive handling, making her a joy to sail for those accustomed to more performance-oriented dinghies.
Accommodations and Layout
The Dufour T7 is notably designed with a center cockpit, an unusual feature for a boat of this length, which contributes to its efficient use of interior space. This layout allows for two separate cabins, a significant achievement for a vessel under 22 feet. While specific headroom figures are not consistently available, the interior arrangement typically includes sleeping berths, a small galley area, and potentially a compact head compartment. Owners often describe the interior as functional, though some indicate that the original interior finishes can be prone to wear over time, often requiring cosmetic work. The separation of sleeping areas, with an aft cabin accessible from the cockpit, enhances privacy and comfort for a boat of this size, making her suitable for weekend cruising or short-term liveaboards.
Owner's Perspectives
Owners of the Dufour T7 generally appreciate her solid construction and comfortable motion in a seaway, often highlighting her nimble and enjoyable sailing performance. The unique manually adjustable centerboard system is a frequently discussed feature, generally proving reliable, although some owners have reported maintenance needs related to the lifting keel mechanism over time. The central cockpit design is a strength, providing a secure and comfortable helm position, especially for family sailing. However, some owners note that the placement of engine controls can be inconvenient for the helmsman, leading some to install a transom-mounted chair for better access. Despite minor quirks, the T7 has fostered a strong and active community of enthusiasts, indicating a loyal following for this innovative and compact cruiser.
