About the Swan 55

Launched in 2021, this latest addition to Nautor Swan's prestigious lineup represents a masterful collaboration with renowned designer German Frers. The Swan 55 exemplifies the Finnish builder's commitment to creating sophisticated performance cruisers that seamlessly blend racing pedigree with luxurious comfort. At nearly 60 feet overall, this fractional sloop showcases modern design elements including a fin keel with dual rudders, delivering exceptional handling and responsiveness whether coastal cruising or offshore passage making. The GRP construction maintains Swan's legendary build quality while keeping displacement reasonable for spirited performance. With a comfort ratio of 34.34, the boat strikes an ideal balance between seaworthiness and speed, making it equally suited for competitive sailing and extended cruising adventures. The relatively low capsize screening value of 1.79 reflects excellent stability characteristics, inspiring confidence in challenging conditions. Her hull speed of 9.64 knots ensures brisk passages under sail, while the 110-horsepower engine provides reliable auxiliary power. True to Swan's reputation, this model attracts discerning sailors who demand uncompromising quality, sophisticated styling, and the ability to cruise comfortably to distant horizons while maintaining the option to compete successfully in regattas.

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
 51
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
 33.54
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
 159.25
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
 34.34
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
 1.79
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. 9.64 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
