About the Contessa 25 Peterson

Designed by Doug Peterson and built by Jeremy Rogers, this rare sailboat represents a fascinating chapter in 1970s yacht design with only ten hulls ever constructed starting in 1975. The Peterson-designed Contessa 25 showcases the designer's signature approach to performance-oriented sailing with its fin keel and spade rudder configuration, delivering responsive handling characteristics that Peterson became renowned for in his racing designs. With a displacement of 4,600 pounds and 2,100 pounds of ballast, this fiberglass masthead sloop strikes a balance between stability and performance. The boat's sail area of 350 square feet provides ample power for spirited sailing, while the SA/Displacement ratio of 20.3 indicates good performance potential in moderate conditions. Her comfort ratio of 16.11 suggests a motion more suited to day sailing and coastal cruising rather than extended offshore passages. The hull's moderate proportions, with a waterline length of 21 feet and beam of 9.42 feet, create a seaworthy platform ideal for coastal exploration and weekend adventures. Given Peterson's racing pedigree and the boat's responsive underwater profile, owners can expect engaging sailing characteristics with the capability for club racing. The five-foot draft provides good upwind performance while remaining manageable for most harbor depths.

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
20.3
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
45.65
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
221.74
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
16.11
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. 6.14 kn
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. 706.83 pounds/inch
