The Wrighton Bi-Loup 77 is a distinctive French-built sailboat, renowned for its robust construction and practical twin-keel design that caters specifically to coastal cruisers and families seeking versatility and safety. Produced by Wrighton Yachts, a shipyard celebrated for its accessible and resilient biquille vessels, the Bi-Loup 77, and its later iteration the Bi-Loup 77 NV, offered a unique blend of shallow-draft capability and comfortable accommodations in a compact package. Designed by Wrighton itself, the model embodies the builder's philosophy of creating yachts that emphasize stability, ease of handling, and the ability to dry out on tidal moorings, making it a popular choice in its class.

The Bi-Loup 77 entered production in 1985, with its initial run continuing until 1995, during which approximately 100 to 102 units were built. The builder, Wrighton Yachts, established in 1978, quickly became known for its signature twin-keel (or "biquille") design, a practical engineering solution offering enhanced stability and reduced draft. Richard Wrighton is noted as an early designer for the company, likely instrumental in shaping the foundational identity of models like the Bi-Loup 77. Following the success of the original, an updated version, the Bi-Loup 77 NV, was introduced and built from 1995 until 2009, indicating a significant and sustained demand for this specific model line. This evolution underscored Wrighton's commitment to producing popular cruising yachts designed for family sailing, prioritizing comfort and safety over outright racing performance. The twin-keel configuration remained a defining feature throughout its production, allowing the boat to navigate shallow waters and safely sit upright on the seabed during low tide.

Sailing Performance and Handling

Despite its compact size of just over 25 feet, the Bi-Loup 77 is characterized as a light sailboat with the potential for high performance within its class. Its masthead sloop rig provides a generous sail plan for efficient propulsion. A key attribute of the Bi-Loup 77, stemming from its twin-keel design, is its inherent stability and stiffness, making it a reassuring vessel even in more challenging conditions. The shallow maximum draft of 2.79 feet, a direct benefit of the twin keels, allows the Bi-Loup 77 to access areas inaccessible to deeper-draft vessels and provides the practical advantage of drying out for maintenance or tidal moorings. Owners have anecdotally reported good speed, with one account even mentioning "records de Vitesse absolu et de vitesse moyenne" for the Bi-Loup 77 NV, suggesting that its slightly more speedy hull design contributes to an enjoyable sailing experience. This combination of stability, shallow draft, and responsive handling makes the Bi-Loup 77 well-suited for a variety of cruising grounds.

Accommodations and Layout

The interior of the Bi-Loup 77 is designed with small family cruising in mind, offering a surprising amount of space for a sailboat of its length. It features a generous maximum headroom of 5.9 feet, which is often highlighted by reviewers and owners as a "magnifique hauteur sous barrot" (magnificent headroom), enhancing comfort below deck. While specific details can vary, the Bi-Loup 77 NV, for example, is noted to have a two-cabin layout, likely comprising a V-berth forward and a quarter berth or compact aft cabin, alongside a saloon area and a basic galley. Owners frequently engage in discussions about optimizing the interior layout, indicative of its adaptable nature for personal use. The overall finish, consistent with Wrighton's general ethos, would prioritize functionality and durability suitable for cruising.

Owner's Perspectives

Owners of the Bi-Loup 77 and 77 NV generally praise the boat for its practical design and cruising capabilities. The active "BBC Biloup boat club" signifies a loyal and engaged community, where owners share experiences, modifications, and advice, highlighting the enduring appeal of the model. Many appreciate the twin-keel's advantages for accessing shallow anchorages and the convenience of drying out. The boat is consistently regarded as an ideal choice for "petite croisère en famille" (small family cruising). Demonstrating its robust build and seaworthiness, at least one Bi-Loup owner successfully sailed their boat on an extensive voyage through the doldrums to Brazil and back, showcasing its capabilities beyond mere coastal hops. While discussions often revolve around owner modifications and improvements, there are no widespread or recurring critical weaknesses commonly cited, suggesting a generally reliable and well-regarded vessel within its niche.
