About the Sun Odyssey 350 Jeanneau

Jeanneau's Sun Odyssey 350 represents a fresh take on the compact cruising sailboat market, launching in 2024 with modern design sensibilities from the talented duo of Marc Lombard and Jean-Marc Piaton. This 34-foot fractional sloop strikes an appealing balance between performance and comfort, making it well-suited for coastal cruising and weekend adventures. The yacht's fin keel with bulb and dual rudder configuration delivers responsive handling and improved maneuverability, particularly beneficial when navigating tight harbors or anchorages. With a displacement of 12,469 pounds and generous sail area of 592 square feet, the boat offers spirited sailing performance while maintaining stability for comfortable cruising. The SA/Displacement ratio of 17.68 suggests lively performance in light to moderate conditions. Built with Jeanneau's proven GRP construction methods, the Sun Odyssey 350 incorporates the builder's decades of experience in creating practical cruising yachts. The fractional rig simplifies sail handling while the 29-horsepower engine provides reliable auxiliary power. With a comfort ratio of 22.71, this yacht prioritizes sailing performance over heavy-weather comfort, making it ideal for active sailors who enjoy responsive boat handling over maximum interior volume.

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
17.68
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
27.93
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
191.08
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
22.71
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
2.04
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. 7.43 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. 1,295.15 pounds/inch
