About the Requin

Designed by renowned Finnish naval architect Gunnar L. Stenbäck in 1930, this classic fractional sloop represents the golden age of yacht design when craftsmanship and seaworthiness were paramount. With 500 hulls built over the years, the Requin has proven its enduring appeal among sailors who appreciate traditional construction and reliable performance. The boat's long keel configuration and impressive comfort ratio of 20.57 make it exceptionally well-suited for coastal cruising and extended offshore passages. Its wood and fiberglass construction combines the beauty of traditional materials with modern durability. The 31.50-foot overall length provides comfortable accommodations while remaining manageable for a small crew. At 3,748 pounds displacement with a moderate sail area of 238 square feet, this design prioritizes stability and comfort over raw speed. The capsize screening formula of 1.61 indicates excellent seaworthiness, while the hull speed of 6.23 knots offers respectable passage-making capability. The narrow 6.23-foot beam contributes to the boat's elegant lines and efficient motion through the water. For sailors seeking a proven bluewater cruiser with classic aesthetics and forgiving handling characteristics, the Requin offers an attractive combination of safety, comfort, and timeless design that has stood the test of nearly a century.

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
15.82
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
164.88
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
20.57
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
1.61
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. 6.23 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. 481.94 pounds/inch
