About the S2 35

Produced by S2 Yachts, a Michigan-based builder with a strong reputation for quality fiberglass construction throughout the 1970s and 1980s, the S2 35 represents the brand's commitment to building capable, well-finished sailboats for the serious recreational sailor. S2 Yachts earned considerable respect during its era for producing boats that balanced performance with comfort, and the 35 fits squarely within that philosophy. Suited primarily for coastal and inland cruising, the S2 35 appeals to sailors who want a responsive, manageable boat without sacrificing the creature comforts that make longer passages enjoyable. The hull design reflects the performance sensibilities common to S2's lineup, offering a lively sailing experience while remaining accessible to a range of skill levels. Owners often praise the build quality and attention to detail that characterized S2's production during its peak years. For buyers researching a used cruiser-racer in this size range, the S2 35 is worth serious consideration. Its combination of solid construction heritage and versatile sailing characteristics makes it a practical choice for those looking to explore beyond the marina without committing to a dedicated offshore vessel.

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
17.05
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
26.16
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
1.94
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
