About the Sun Light 30 Jeanneau

Designed by Daniel Andrieu and launched in 1986, this French-built sailboat represents Jeanneau's approach to creating an accessible yet capable cruising yacht for coastal and near-shore sailing. The Sun Light 30 combines moderate displacement with a contemporary fin keel and spade rudder configuration, delivering responsive handling characteristics that appeal to both recreational sailors and those seeking weekend adventure. With its masthead sloop rig and well-proportioned sail plan, the boat offers straightforward sail handling while maintaining good performance across varying wind conditions. The SA/Displacement ratio of 19.57 indicates lively sailing characteristics, while the comfortable 17.06 comfort ratio suggests reasonable motion at sea for a boat of this size. The hull's fiberglass construction ensures durability and relatively low maintenance requirements. At just over 30 feet overall, this Jeanneau strikes a balance between manageable size and interior volume, making it particularly well-suited for coastal cruising, day sailing, and short-handed operation. The moderate draft allows access to shallow anchorages, while the substantial ballast ratio provides stability and confidence under sail. The capsize screening value of 2.24 places it within acceptable parameters for coastal sailing, though offshore passages would require careful weather planning. This model represents solid French boatbuilding during an era when Jeanneau was establishing its reputation for producing reliable, well-designed cruising sailboats.

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
19.57
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
38.78
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
189.51
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
17.06
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
2.24
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. 6.73 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
3.13
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. 956.34 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. 19.55
