About the Winslow 36

Relatively little documentation has survived about the Winslow 36, making it one of the more elusive designs for researchers digging into mid-century American sailboat production. What is known suggests this was a cruising-oriented vessel built with an eye toward comfortable passage-making rather than outright racing performance. The 36-foot length places it firmly in a practical range favored by bluewater-minded sailors looking for a capable offshore boat that remains manageable for a small crew or experienced couple. Without a robust set of published specifications, prospective buyers should approach any Winslow 36 with thorough due diligence, commissioning a qualified marine survey to assess the hull, rig, and systems. Given the vintage nature of most examples likely to appear on the market, condition will vary considerably from boat to boat, making hands-on inspection essential. For those drawn to classic sailboat design and willing to invest time in research and potential restoration, the Winslow 36 may represent an intriguing opportunity. Reaching out to historical yacht registries or long-standing sailing communities may help uncover additional design details and owner experiences.

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
15.22
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
41.65
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
1.53
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. 6.7
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
0.85
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. 848.61
