About the Jeanneau One Design 24

Daniel Andrieu's design for Jeanneau delivers a compelling blend of performance and versatility in this compact 24-footer, first launched in 1994. The lifting keel configuration makes this boat particularly appealing for sailors who need shallow-water capability without sacrificing sailing performance, allowing access to protected anchorages and launching ramps while maintaining the ballast efficiency needed for spirited sailing. With a fractional sloop rig and sail area of 247 square feet driving 2,530 pounds of displacement, the One Design 24 offers lively performance characteristics well-suited to day sailing, coastal cruising, and club racing. The SA/Displacement ratio of 21.34 indicates a responsive boat that will move well in light to moderate conditions, while the 726-pound ballast provides adequate stability for confident sailing. The fiberglass construction reflects Jeanneau's production boat expertise, delivering durability and reasonable maintenance requirements. At nearly 24 feet overall with an 8.17-foot beam, there's sufficient space for weekend cruising or extended day trips with a small crew. The comfort ratio of 10.98 suggests this design prioritizes performance over heavy-weather comfort, making it ideal for coastal waters rather than offshore passages. The capsize screening value of 2.4 indicates good stability characteristics for its intended use.

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
21.34
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
28.7
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
126.42
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
10.98
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
2.4
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. 6.10 kn
S# (Speed Number) The Speed Number (S#) is a quick performance index. Higher values indicate a faster, more powerful design relative to its size.
Under 3.0 — Slow cruiser3.0–5.0 — Average cruiser5.0–7.0 — Performance cruiserOver 7.0 — Racer
4.39
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. 605.74 pounds/inch
SA/Displacement (Calc) Calculated Sail Area to Displacement ratio using actual measured sail dimensions rather than reported values. More precise than the reported SA/Disp figure. 21.34
