About the Sun 1030

Produced by the French builder Jeanneau, the Sun 1030 is a compact cruiser-racer that reflects the practical, performance-oriented design philosophy that defined much of Jeanneau's lineup during its era. Built for sailors who want versatility without committing to a larger vessel, this boat strikes a balance between manageable size and genuine sailing capability, making it a solid choice for inshore and coastal cruising as well as casual racing on club circuits. With limited specification data widely available, the Sun 1030 remains something of a niche find on the secondhand market, appealing primarily to experienced buyers who already have familiarity with the model. Its Jeanneau heritage suggests a well-constructed hull with attention to interior practicality, a hallmark of the brand's approach to accessible sailing. The compact proportions make it well suited to sailors looking for a responsive, easy-to-handle boat that can be managed with a small crew or even singlehanded in the right conditions. For those willing to research the model thoroughly, the Sun 1030 can represent good value in a capable, characterful small cruiser.

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
 18.45
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
 22.37
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. 7.09
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
