Designed by Michel Joubert and built by France's Chantier Alubat from 1976 to 1980, this aluminum cruiser represents an early example of the builder's commitment to robust offshore construction. The Ovni 31's aluminum hull provides exceptional durability and corrosion resistance, making it particularly well-suited for extended coastal and offshore cruising where low maintenance is paramount. With a displacement of 8,378 pounds and substantial ballast of 3,527 pounds, this masthead sloop offers reassuring stability for serious cruising applications. The fin keel with rudder on skeg configuration strikes a practical balance between performance and protection, while the moderate sail area of 570.49 square feet ensures manageable handling for smaller crews. The boat's comfort ratio of 20.83 indicates a motion that favors seaworthiness over speed, typical of vessels designed for long-distance voyaging rather than racing. Her SA/Displacement ratio of 22.2 suggests moderate performance characteristics well-suited to cruising sailors who prioritize reliability over pure speed. The aluminum construction, combined with Joubert's proven design philosophy, makes this an attractive option for sailors seeking a dependable platform for serious coastal exploration or offshore passages where durability and low maintenance requirements are essential considerations.
