About the Wianno Junior

Designed by H. Manley Crosby in 1921, this classic wooden daysailer represents nearly a century of refined New England sailing tradition. Built by Crosby Yacht Building And Storage Co., the Wianno Junior embodies the timeless elegance of Cape Cod's maritime heritage with its traditional construction and proven seaworthiness. At 16.5 feet overall with a 6-foot beam, this fractional sloop offers an ideal balance of stability and performance for coastal sailing and sailing instruction. The 300-pound ballast in a 900-pound displacement provides reassuring stability, while the keel/centerboard configuration allows for both deeper water sailing and shallow harbor exploration. With 150 square feet of sail area, the boat delivers spirited performance without being overpowering for newer sailors. The Wianno Junior's low comfort ratio of 9.09 and moderate capsize screening value of 2.49 indicate its design priorities favor performance over accommodation, making it perfectly suited for day sailing, sailing education, and junior racing programs. Its 4.83-knot hull speed provides respectable pace for a boat of this size. Though only 80 were built, the Wianno Junior remains a cherished example of classic American small boat design, offering modern sailors an authentic connection to traditional seamanship and craftsmanship.

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
25.79
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
33.33
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
182.88
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
9.09
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
2.49
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. 4.83 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. 278.70 pounds/inch
