About the S2 35C

Produced by S2 Yachts, the Michigan-based builder known for crafting well-finished, performance-oriented sailboats throughout the 1970s and 1980s, the 35C represents a capable mid-range cruiser-racer that found a loyal following among sailors seeking a versatile all-rounder. S2 Yachts built a reputation for quality construction and thoughtful design during this era, and the 35C reflects that heritage with a hull shape and layout aimed at balancing speed with comfort. Suited to coastal cruising and weekend racing alike, this boat appeals to sailors who want competitive performance on the racecourse without sacrificing the livability needed for longer passages or family outings. The 35C is generally regarded as a well-mannered boat that rewards attentive sailing while remaining forgiving enough for less experienced crews. With limited specification data readily available, prospective buyers are encouraged to seek out existing owners and class communities, where firsthand accounts of the boat's handling characteristics and long-term ownership experience can provide valuable insight. Hull inspections and surveys are always recommended when researching any used vessel of this vintage.

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
16.42
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
27.53
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
1.91
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. 7.13
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
