About the Hylas 55

Designed by renowned naval architect German Frers and built by Queen Long Marine in Taiwan starting in 1997, this sophisticated 55-footer represents the pinnacle of performance cruising yacht design. The Hylas 55 combines elegant lines with serious blue-water capability, making it equally at home crossing oceans or exploring coastal waters in comfort and style. The yacht's fin keel with bulb and spade rudder configuration provides excellent upwind performance while maintaining good stability, characteristics that reflect Frers' racing pedigree. With a displacement of 47,184 pounds and substantial ballast of 20,015 pounds, the Hylas 55 offers the security serious cruisers demand for extended offshore passages. The masthead sloop rig delivers versatile sail handling options and strong performance across various wind conditions. Built with quality fiberglass construction, these yachts have earned a reputation for robust build quality and attention to detail. The comfort ratio of 38.14 suggests a boat that strikes an excellent balance between performance and comfort, while the capsize screening value of 1.75 indicates good stability characteristics for offshore work. Hull speed potential of over 9 knots meansrespectable passage-making ability under sail, making this an ideal choice for serious cruising sailors who refuse to compromise on performance.

Performance Ratios
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
 42.42
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
 219.98
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
 38.14
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. 9.06 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. 2,574.65 pounds/inch
