About the Contest 30

Built by Dutch manufacturer Coniplex from 1974 to 1978, this 30-footer represents the craftsmanship and seaworthiness that would later define the Contest Yachts brand. Designer Dick Zaal created a well-balanced cruising sailboat that prioritizes comfort and stability over pure performance, evident in its conservative design ratios and substantial construction. The Contest 30's fin keel with rudder on skeg configuration provides good directional stability while maintaining reasonable maneuverability. With a displacement of 8,820 pounds and 4,000 pounds of ballast, this yacht offers reassuring stability for coastal cruising and short offshore passages. The masthead sloop rig with 362 square feet of sail area delivers adequate performance without being overpowering for shorthanded sailing. The boat's comfort ratio of 27.61 indicates a motion that favors comfort over speed, making it well-suited for extended cruising where livability matters more than racing performance. Its capsize screening formula of 1.75 falls within acceptable limits for coastal and near-offshore sailing, though it's best suited for protected waters and fair weather passages. Only 80 examples were built during its four-year production run, making it relatively rare today. The fiberglass construction has proven durable, and many examples remain active in the used boat market, appealing to sailors seeking solid Dutch build quality in an affordable package.

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
224
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
13.61
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
45.35
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
254.43
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
27.61
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
1.75
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. 6.69 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
1.8
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. 801.38 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. 13.63

I (Foretriangle Height) 35.80 ft / 10.91 m
