About the Xp 50

Designed by renowned Danish naval architect Niels Jeppesen and built by the prestigious X Yachts shipyard, this sophisticated 51-foot performance cruiser represents the Danish builder's commitment to combining racing pedigree with comfortable cruising capabilities. Launched in 2013, the Xp 50 embodies X Yachts' philosophy of creating boats that excel both on the racecourse and during extended offshore passages. The yacht's fractional sloop rig and generous sail area deliver impressive performance potential, while the fin keel with bulb and spade rudder configuration provides excellent upwind ability and responsive handling. With a displacement of nearly 30,000 pounds and substantial ballast ratio, the boat offers reassuring stability for offshore sailing while maintaining the light feel characteristic of modern performance designs. The hull's moderate comfort ratio of 28.6 suggests a design optimized for speed rather than pure comfort, making it ideal for sailors who prioritize performance without sacrificing seaworthiness. The capsize screening formula of 1.87 indicates good stability characteristics suitable for offshore work. This combination of Danish craftsmanship, thoughtful design, and robust construction makes the Xp 50 particularly appealing to experienced sailors seeking a capable boat for serious coastal and offshore sailing adventures.

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
27.4
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
41.18
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
160.72
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
28.6
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
1.87
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. 8.86 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. 2,267.23 pounds/inch
