About the Designers

The Bénéteau Oceanis 351 was designed by Jean Berret and Olivier Racoupeau. Both designers are well-known in the world of yacht design, particularly for their work with the French boatbuilding company Bénéteau.

Jean Berret was the chief designer and responsible for many of Bénéteau's designs in the 1980s and 1990s. He is recognized for creating boats that are both performance-oriented and easy to handle, with a focus on comfort and space. Olivier Racoupeau, who worked alongside Berret, is also a highly respected designer, known for his work on many of the Bénéteau cruising and racing yachts. Racoupeau's influence can be seen in the sleek, modern lines and functional layouts of the Oceanis series.

The Oceanis 351, introduced in 1991, was part of the Oceanis range, which was Bénéteau's line of cruising yachts. The design of the 351 was aimed at offering a balance between performance and comfort, with a spacious interior layout, solid sailing characteristics, and relatively easy handling for short-handed crews.

The Oceanis 351 was popular for its versatility, comfort, and good sailing performance, making it a well-regarded option for cruising sailors at the time.
