About the Sun Liberty 34 Jeanneau

Built from 1989 to 1992, the Sun Liberty 34 represents Jeanneau's successful foray into performance-oriented cruising during the late 1980s boom. Designer Daniel Andrieu created a well-balanced 33-footer that appeals to sailors seeking both comfort and sailing ability, evidenced by the production of 284 hulls over its four-year run. The yacht's fiberglass and Kevlar construction provides strength while keeping weight reasonable, contributing to its respectable sail area-to-displacement ratio of 22.16. The fin keel with bulb and spade rudder configuration delivers responsive handling and good upwind performance, making this boat equally suited for coastal cruising and club racing. With a masthead sloop rig carrying 656 square feet of sail, the Liberty 34 offers straightforward sail handling for shorthanded crews. Notable characteristics include a moderate comfort ratio of 21.94, suggesting comfortable motion in typical cruising conditions, while the capsize screening value of 2.11 indicates reasonable stability for coastal and near-offshore sailing. The hull's 6.88-knot theoretical hull speed provides adequate passage-making capability under sail, complemented by a reliable 27-horsepower auxiliary engine. This design strikes an appealing balance between performance and practicality for sailors prioritizing sailing characteristics alongside cruising comfort.

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
 22.16
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
 32.34
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
 251.98
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
 21.94
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
 2.11
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. 6.88 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
 2.05
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. 1,082.09 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. 15.94
