About the Comet 700

Designed by the renowned French firm Groupe Finot and built by Italy's Comar from 1980 to 1988, this 23-foot sailboat represents European design sensibilities of the early 1980s racing scene. With only 217 hulls produced during its eight-year production run, the Comet 700 remains a relatively uncommon sight on today's waters. The boat's fin keel configuration with transom-hung rudder delivers responsive handling characteristics that made it appealing to both club racers and weekend sailors. Its masthead sloop rig provides a generous sail area of 290 square feet, offering spirited performance in light to moderate conditions. The relatively low comfort ratio of 13.29 reflects the boat's sport-oriented design priorities, emphasizing speed over long-distance cruising amenities. Built with fiberglass construction typical of its era, the Comet 700 suits coastal sailing and day racing particularly well. The moderate displacement of 2,866 pounds with 811 pounds of ballast creates a boat that's both manageable for smaller crews and stable enough for spirited sailing. While not designed for extended offshore passages, this Italian-built design offers an engaging sailing experience for those seeking performance-oriented coastal adventures with classic 1980s racing yacht characteristics.

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
23.06
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
28.3
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
167.86
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
13.29
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
2.27
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. 5.94 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
3.21
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. 565.36 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. 17.7
