About the Wilderness 38

Designed by renowned naval architect Gary Mull and built by Wilderness Yachts starting in 1979, this 38-footer represents a thoughtful balance between performance and practicality. With its moderate displacement of 9,000 pounds and generous sail area of 596 square feet, the Wilderness 38 delivers spirited sailing characteristics while maintaining reasonable stability for coastal cruising and occasional offshore passages. The fin keel and spade rudder configuration provides responsive handling and good upwind performance, hallmarks of Mull's design philosophy during this era. At 38.25 feet overall with a 30-foot waterline, the boat offers a respectable hull speed of 7.34 knots, while the substantial ballast-to-displacement ratio of 50% ensures adequate stability for extended cruising. The comfort ratio of 15.65 suggests a relatively stiff, quick motion that favors performance over pure comfort, making this boat particularly appealing to sailors who prioritize sailing ability. The capsize screening value of 2.31 indicates reasonable offshore capability, though the design is best suited for coastal cruising and club racing. Gary Mull's reputation for creating well-balanced designs that don't compromise sailing performance makes the Wilderness 38 an attractive option for sailors seeking a capable, versatile cruiser-racer from the late 1970s era.

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
22.11
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
50
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
148.81
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
15.65
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
2.31
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. 7.34 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. 1,286.32 pounds/inch
