About the Sun Odyssey 49 Ds Jeanneau

Designed by the respected naval architecture team of Garonni and Briand, this 49-foot cruiser represents Jeanneau's commitment to blending performance with comfort for serious blue-water sailing. The Sun Odyssey 49 DS launched in 2004 as part of Jeanneau's evolution toward more sophisticated offshore cruising yachts, featuring a sleek hull form optimized for both coastal and ocean passages. The masthead sloop rig configuration delivers impressive sail-handling ease while maintaining strong upwind performance, thanks to its well-balanced 977 square feet of working sail area. The fin keel with bulb and spade rudder arrangement provides excellent maneuverability and tracking, while the substantial 9,039-pound ballast ensures stability in challenging conditions. With a displacement of 28,000 pounds and a moderate comfort ratio of 23.58, this yacht strikes an appealing balance between spirited sailing characteristics and the solid, secure feel that offshore cruisers demand. The fiberglass construction reflects Jeanneau's decades of production boat expertise, while the 75-horsepower auxiliary engine provides reliable motoring capability. Whether planning extended coastal cruising or contemplating ocean crossings, the Sun Odyssey 49 DS offers the seaworthiness and accommodation space that makes long-distance sailing both safe and comfortable for couples or small crews.

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
 17.02
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
 32.28
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
 164.92
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
 23.58
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
 2.16
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. 8.72 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
 3.16
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. 2,475.37 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. 17.03
