About the X 402

Danish builder X-Yachts produced this capable 40-footer from 1984 to 1990, with 79 hulls launched during its production run. Designed by Niels Jeppesen, the X 402 represents the builder's commitment to combining performance with cruising comfort in a well-balanced package. The boat's moderate displacement of 13,200 pounds and generous sail area of 703 square feet create a responsive performer that excels in both coastal cruising and club racing scenarios. Her fractional sloop rig and fin keel configuration with spade rudder deliver crisp handling characteristics typical of European designs from this era. The substantial ballast-to-displacement ratio of over 50% provides excellent stability and stiff sailing in a blow. Built with fiberglass construction to X-Yachts' exacting Danish standards, the X 402 earned a reputation for solid build quality and attention to detail. The comfortable cockpit and well-appointed interior make extended coastal passages enjoyable, while her sailing characteristics satisfy performance-oriented sailors. With a low comfort ratio indicating a sportier nature, she bridges the gap between pure racers and heavy cruising boats. This design suits sailors seeking a well-built European yacht capable of spirited day sailing, weekend cruising, and competitive club racing in protected to moderate offshore conditions.

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
 78
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
 20.21
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
 51.67
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
 161.47
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
 19.24
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
 2.19
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. 7.72 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
 3.63
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. 1,531.28 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. 20.23
