About the H 35

Designed by Hans Groop and built by Finnish yard Artekno from 1975 to 1986, this 35-footer represents solid Scandinavian craftsmanship with 280 hulls produced during its eleven-year production run. The H 35's moderate displacement of 7,716 pounds and substantial ballast-to-displacement ratio of 43% create a stable platform that inspires confidence in challenging conditions. The fractional sloop rig and fin keel with rudder on skeg configuration deliver responsive handling while maintaining directional stability. With a sail area to displacement ratio of 16.07, the boat offers respectable performance without being overpowered, making it well-suited for both coastal cruising and longer offshore passages. The conservative comfort ratio of 23.57 suggests motion characteristics that favor comfortable cruising over racing-oriented quick motion. Hull speed of 6.91 knots and the favorable capsize screening value of 1.73 indicate seaworthy design suitable for serious blue-water sailing. The fiberglass construction has proven durable over the decades, with many examples still actively sailing today. Finnish build quality, combined with Groop's thoughtful design approach, created a yacht that balances cruising comfort with sailing performance, making it an attractive option for sailors seeking a capable mid-size cruiser with European pedigree.

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
 16.07
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
 43.43
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
 183.43
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
 23.57
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
 1.73
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. 6.91 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
 2.79
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. 810.12 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. 16.06
