About the Comet 11

Designed by the renowned French firm Groupe Finot and built by Italy's Costruzioni Marittime Comar from 1977 to 1993, this 35-footer represents a thoughtful balance between performance and practicality. With 187 hulls produced over its 16-year production run, the Comet 11 earned a solid reputation among European sailors seeking a capable coastal cruiser with racing potential. The yacht's moderate displacement of 12,345 pounds and substantial ballast ratio provide excellent stability, while the fin keel with rudder-on-skeg configuration delivers responsive handling and directional stability. Her sail area-to-displacement ratio of 17.55 indicates spirited performance in light to moderate conditions, making her well-suited for both club racing and weekend cruising. The fiberglass construction and masthead sloop rig keep maintenance straightforward, while the comfortable beam of nearly 12 feet provides generous interior volume for extended cruising. With a capsize screening value of 2.05, she falls within acceptable parameters for coastal and near-offshore sailing, though her comfort ratio of 22.75 suggests a livelier motion in seaways. The Comet 11 appeals to sailors seeking a versatile platform that can handle both competitive sailing and comfortable cruising in protected to semi-protected waters.

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
 17.55
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
 41.07
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
 214.02
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
 22.75
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
 2.05
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. 7.28 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
 2.61
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. 1,246.12 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. 17.55
