About the Mg 335

Few sailboats manage to blend performance and practicality as seamlessly as this French-designed 33-footer from the renowned Jeanneau stable. Built during the 1980s, the Mg 335 represents a compelling example of European cruiser-racer philosophy, where weekend racing capability meets comfortable coastal cruising accommodations. Her moderate displacement hull strikes an appealing balance between speed and stability, making her well-suited for both spirited day sailing and extended coastal passages. The boat's relatively beamy design provides generous interior volume without sacrificing sailing performance, a hallmark of intelligent French yacht design from this era. What sets the Mg 335 apart is her reputation for being remarkably well-mannered in varying conditions. Owners consistently praise her predictable handling characteristics and solid construction quality, traits that have helped many examples remain actively sailed decades after launch. The cockpit layout emphasizes both comfort and functionality, while below decks, the accommodation plan maximizes the available space efficiently. For sailors seeking a capable coastal cruiser with racing pedigree, the Mg 335 offers proven seaworthiness wrapped in classic 1980s styling. Her combination of performance potential and cruising comfort continues to attract discerning sailors looking for versatile offshore capability.
