About the Wasa 37

Swedish designer Leif Ängermark created this well-balanced coastal cruiser in 1985, and Wasa Marin built it with the quality craftsmanship expected from Scandinavian yards. The Wasa 37 represents solid European design philosophy, emphasizing seaworthiness and comfort over pure performance. With its fin keel and spade rudder configuration, this masthead sloop delivers responsive handling while maintaining excellent stability through its substantial 5,510-pound ballast ratio. The moderate displacement of 11,770 pounds strikes an appealing balance between cruising comfort and sailing performance, making it well-suited for extended coastal passages and weekend adventures alike. The boat's generous beam of 10.33 feet creates spacious accommodations below while contributing to initial stability. A comfort ratio of 25.97 indicates this yacht prioritizes livability over racing characteristics, though the sail area to displacement ratio of 18.71 suggests adequate performance in light to moderate conditions. The capsize screening formula of 1.82 falls within acceptable parameters for offshore coastal work. Hull speed capabilities of 7.20 knots provide respectable passage-making potential, while the fiberglass construction ensures durability and manageable maintenance. This Swedish design appeals to sailors seeking a capable, well-mannered cruiser that handles northern European conditions with confidence while offering comfort for extended voyaging.

Performance Ratios
PHRF Rating PHRF (Performance Handicap Racing Fleet) is a national racing handicap measured in seconds per nautical mile. Lower values indicate faster boats. Ratings are sourced from US Sailing's national database (median across 60+ regional fleets).
Under 0 — Ultralight racer0–90 — Performance racer90–150 — Cruiser/racer150–210 — Typical cruiserOver 210 — Heavy/slow cruiser
 132
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
 18.71
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
 46.81
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
 218.14
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
 25.97
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
 1.82
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. 7.20 kn
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
 2.68
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. 1,065.97 pounds/inch
SA/Displacement (Calc) Calculated Sail Area to Displacement ratio using actual measured sail dimensions rather than reported values. More precise than the reported SA/Disp figure. 18.7
