About the Swan 70

Launched in 2001 and produced through 2005, this elegant 70-footer represents Nautor's Swan's commitment to combining serious offshore performance with luxurious cruising comfort. Designed by the renowned German Frers, only seven hulls were built, making this a relatively exclusive yacht in Swan's distinguished lineup. With its fin keel and bulb configuration paired with a spade rudder, the Swan 70 delivers the responsive handling expected from a modern performance cruiser. The masthead sloop rig carries 2,500 square feet of sail area, providing excellent power for both spirited coastal sailing and extended offshore passages. The SA/Displacement ratio of 24.57 indicates a boat that will move well in moderate conditions while maintaining the stability needed for blue water cruising. The impressive 66,138-pound displacement and substantial ballast ratio contribute to exceptional seaworthiness, while the comfortable 35.17 comfort ratio suggests this yacht prioritizes long-distance cruising capability over pure racing performance. The low capsize screening value of 1.74 further reinforces its offshore credentials. Built with Nautor's legendary fiberglass construction quality, the Swan 70 appeals to discerning sailors seeking a premium yacht capable of handling serious ocean voyaging while providing the comfort and elegance synonymous with the Swan brand.

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
 -60
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
 24.57
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
 36.17
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
 125.83
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
 35.17
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
 1.74
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. 10.52 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
 4.93
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. 3,861.22 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. 25.22
