Designed by Daniel Tortarolo and built by Yachting France from 1975 to 1984, this French quarter-tonner represents the evolution of small coastal cruisers during the late 1970s racing boom. The Sud 25's relatively long waterline of 21 feet compared to its 23.62-foot overall length creates an efficient hull form that maximizes sailing performance while maintaining manageable proportions for a small crew. With 330 square feet of sail area in a masthead sloop configuration, the boat offers spirited performance typical of French designs from this era. The fin keel with transom-hung rudder provides responsive handling, while the substantial ballast-to-displacement ratio of nearly 47% ensures good stability and seaworthiness for coastal adventures. The boat's moderate beam of 8.86 feet strikes a balance between interior volume and sailing efficiency, while the 4.92-foot draft allows access to most harbors while providing adequate stability. Her comfort ratio of 14.97 suggests relatively quick motion in seaway, characteristic of performance-oriented designs, while the capsize screening value indicates she's best suited for protected waters and near-coastal sailing. This fiberglass construction represents solid French boatbuilding during the quarter-ton class's heyday, making it an interesting choice for sailors seeking vintage racing heritage with practical coastal cruising capability.
