About the Frers 41

Designed by renowned Argentine naval architect German Frers and built by Carroll Marine starting in 1987, this elegant 40.50-foot sloop represents classic performance cruising from the late 1980s. The Frers 41 showcases the designer's signature blend of graceful lines and serious sailing capability that made his designs favorites among discerning sailors worldwide. With a moderate displacement of 15,950 pounds and substantial ballast of 6,600 pounds positioned in a fin keel with spade rudder configuration, the boat offers excellent stability and responsive handling. The comfortable 23.44 comfort ratio suggests this yacht prioritizes seaworthiness over extreme performance, making it well-suited for extended coastal cruising and offshore passages. The capsize screening formula of 2.08 indicates good stability characteristics for ocean sailing. The masthead sloop rig carries 775 square feet of sail area, providing a sail-area-to-displacement ratio of 19.64 that delivers spirited performance without being overly aggressive. This balance makes the Frers 41 accessible to couples or small crews while maintaining the ability to cover miles efficiently. The fiberglass construction ensures durability, while the 35-horsepower auxiliary engine provides reliable power for maneuvering and motorsailing in light conditions.

Performance Ratios
PHRF Rating PHRF (Performance Handicap Racing Fleet) is a national racing handicap measured in seconds per nautical mile. Lower values indicate faster boats. Ratings are sourced from US Sailing's national database (median across 60+ regional fleets).
Under 0 — Ultralight racer0–90 — Performance racer90–150 — Cruiser/racer150–210 — Typical cruiserOver 210 — Heavy/slow cruiser
 72
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
 19.64
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
 41.38
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
 226.09
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
 23.44
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
 2.08
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. 7.53 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
 2.68
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. 1,475.93 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. 19.64
