About the Najad 380

Swedish craftsmanship meets modern performance in this well-regarded cruising sailboat from Najad Yachts. Designed by the acclaimed Judel/Vrolijk team and first launched in 2007, this 38-footer represents a thoughtful balance between comfort and sailing capability that has earned respect among serious cruising sailors. The boat's fractional sloop rig and fin keel with rudder on skeg configuration deliver responsive handling while maintaining the directional stability prized for long-distance cruising. With a displacement of just over 20,000 pounds and nearly 700 square feet of sail area, she offers spirited performance without sacrificing the solid, seaworthy feel that characterizes Najad's reputation. Built with fiberglass construction to Swedish standards, the 380 excels in coastal and offshore cruising applications. Her comfort ratio of 33.33 indicates a motion that's manageable in moderate seas, while the capsize screening value of 1.77 suggests good stability characteristics for extended passages. The design philosophy emphasizes practical seamanship over pure speed, making this an excellent choice for couples or small crews planning serious cruising adventures. Najad's attention to build quality and the proven Judel/Vrolijk hull design have established this model as a reliable platform for both European coastal sailing and longer offshore passages.

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
 126
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
 15.03
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
 34.06
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
 261.38
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
 33.33
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
 1.77
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. 7.64 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
 1.88
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. 1,389.17 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. 15.03
