About the Sud 25

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.

Performance Ratios
SA/Displacement Sail Area to Displacement ratio measures how much sail power a boat has relative to its weight. Higher values mean more performance and speed.
Under 14 — Heavy cruiser, slow14–18 — Cruising sailboat18–22 — Cruiser/racerOver 22 — Performance racer
21.52
Ballast/Displacement Ballast to Displacement ratio shows what percentage of the boat's total weight is ballast. Higher values generally mean better initial stability and stiffer sail carrying.
30–35% — Typical cruiser35–45% — Stiff performance boatOver 45% — Racing oriented
46.86
Displacement/Length Displacement to Length ratio measures how heavy a boat is relative to its waterline length. Lower values mean a lighter, faster boat.
Under 100 — Ultralight racer100–200 — Light cruiser/racer200–300 — Moderate cruiser300–400 — Heavy cruiserOver 400 — Very heavy
185.98
Comfort Ratio Ted Brewer's Comfort Ratio predicts how comfortable a boat will feel in offshore conditions. Higher values mean a steadier, more comfortable motion in a seaway.
Under 20 — Uncomfortably rough20–30 — Acceptable coastal30–40 — Good offshore comfortOver 40 — Very comfortable offshore
14.97
Capsize Screening Formula The USHS Capsize Screening Formula estimates offshore capsize risk. Lower is safer — values under 2.0 are considered acceptable for offshore sailing.
Under 2.0 — Safe for offshore2.0–2.2 — Borderline offshoreOver 2.2 — Coastal use recommended
2.26
Hull Speed Hull Speed is the theoretical maximum speed of a displacement hull, calculated from waterline length. Most cruising sailboats reach this speed in moderate conditions. 6.14 kn
Pounds/Inch Immersion Pounds per Inch Immersion (PPI) tells you how much weight is needed to sink the boat one inch. Useful for calculating how additional gear and stores affect waterline. 664.81 pounds/inch
