About the S2 67 Fk

Designed by Don Wennersten and produced by S2 Yachts from 1980 to 1983, this 22-foot fractional sloop represents a spirited approach to small boat sailing with just 18 hulls ever built. The S2 67 Fk's fin keel configuration and transom-hung rudder provide responsive handling characteristics that make it well-suited for coastal sailing and day trips where agility matters more than cruising comfort. With a displacement of 2,200 pounds and 770 pounds of ballast, this fiberglass boat strikes a balance between stability and performance. The fractional rig configuration offers versatility in sail handling, while the SA/Displacement ratio of 21.43 indicates moderately spirited performance potential. The comfort ratio of 10.8 suggests this boat prioritizes sailing performance over accommodations, making it ideal for sailors who enjoy active participation in the sailing experience. The capsize screening formula of 2.46 falls within acceptable limits for coastal sailing, though the design clearly emphasizes day sailing and short-term cruising over extended offshore passages. Hull speed calculations indicate the boat can achieve speeds around 5.80 knots in optimal conditions. For sailors seeking a rare, performance-oriented pocket cruiser with responsive handling characteristics, the S2 67 Fk offers an intriguing combination of scarcity and sailing capability.

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
 21.43
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
 35
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
 148.99
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
 10.8
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
 2.46
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. 5.80 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
 3.99
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. 535.97 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. 21.44
