About the Sigma 36 Ss

Designed by the legendary naval architecture firm Sparkman & Stephens and built by Hong Kong's respected Cheoy Lee Shipyard starting in 1968, this 36-footer represents classic yacht design from sailing's golden era. The Sigma 36 Ss showcases the hallmarks of S&S craftsmanship with her balanced proportions and seaworthy fin keel configuration paired with a rudder mounted on a skeg for enhanced directional stability. With a displacement of 15,000 pounds and substantial ballast of 7,800 pounds, she's built for serious sailing. The generous beam of 10.25 feet provides comfortable interior volume while maintaining excellent stability. Her masthead sloop rig carries 545 square feet of sail area, delivering a sail area to displacement ratio that favors steady, predictable performance over outright speed. The comfort ratio of 33.59 and favorable capsize screening formula of 1.67 indicate this yacht excels at offshore cruising and passage-making, where her solid construction and conservative design philosophy truly shine. While she may not win weekend club races, the Sigma 36 Ss offers the reliability and seaworthiness that serious cruising sailors seek. Her fiberglass construction ensures longevity, making well-maintained examples excellent choices for coastal and offshore adventures decades after launch.

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
 14.39
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
 52
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
 274.57
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
 33.59
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
 1.67
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. 7.22 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. 1,062.11 pounds/inch
