About the Sun Odyssey 490 Jeanneau

Philippe Briand's design expertise shines through in this modern cruising sailboat that strikes an appealing balance between performance and comfort. Launched in 2018, the Sun Odyssey 490 represents Jeanneau's commitment to creating versatile vessels suited for both coastal adventures and extended offshore passages. The boat's fin keel with bulb and dual rudder configuration delivers responsive handling while maintaining excellent stability in varied conditions. With a fractional sloop rig carrying 1,173 square feet of sail area, the 490 offers spirited performance without overwhelming less experienced crews. The SA/Displacement ratio of 22.1 indicates a boat that will move well in moderate winds while remaining manageable in stronger conditions. At nearly 25,000 pounds displacement, this fiberglass cruiser provides the reassuring heft desired for serious passages, while the comfort ratio of 23.94 suggests motion characteristics well-suited to longer voyages. The capsize screening formula of 2.01 falls within acceptable ranges for offshore work, though the boat truly excels in coastal and near-shore environments. The 57-horsepower auxiliary engine provides adequate power for maneuvering in tight quarters and motoring in calm conditions. Overall, the Sun Odyssey 490 appeals to cruising sailors seeking a modern, well-appointed platform for extended coastal exploration with occasional offshore 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
22.1
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
135.74
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
23.94
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
2.01
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. 8.83 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
3.95
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. 2,275.97 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. 19.45
