About the X 372 Sport

Danish boatbuilder X Yachts launched the X 372 Sport in 1987 as part of their performance-oriented lineup, showcasing designer Niels Jeppesen's talent for creating fast, seaworthy sailing yachts. This 37-footer strikes an impressive balance between racing performance and cruising comfort, featuring a sleek fiberglass hull with fin keel and spade rudder configuration that delivers responsive handling and excellent upwind performance. With a fractional sloop rig carrying 667 square feet of sail area and a relatively light displacement of 11,243 pounds, the X 372 Sport rewards skilled sailors with spirited performance in moderate to heavy air. The substantial ballast-to-displacement ratio of 43% provides reassuring stability, while the low comfort ratio of 20.59 reflects the boat's sport-oriented design philosophy that prioritizes speed over interior volume. The X 372 Sport excels in coastal cruising and club racing scenarios where performance matters. Her capsize screening formula of 2.1 indicates good stability characteristics for offshore passages, though the emphasis remains on spirited day sailing and weekend cruising. X Yachts' reputation for solid construction quality and attention to detail makes this model particularly appealing to sailors seeking a reliable, well-built yacht that can deliver both excitement and dependability on the water.

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
 21.34
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
 43.14
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
 195.51
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
 20.59
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
 2.1
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. 7.28 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
 3.25
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. 1,237.48 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. 21.33
