About the Cnb 78

With limited technical specifications publicly available, the Cnb 78 represents the upper echelon of CNB's luxury performance cruising lineup. This substantial sailing yacht embodies the French builder's commitment to blending sophisticated design with serious sailing capability. CNB has built a reputation for creating yachts that don't compromise between comfort and performance, and the 78-footer appears to continue this tradition. At this size, the boat likely targets experienced sailors seeking a vessel capable of extended offshore passages while maintaining the refinement expected in the luxury sailing market. The Cnb 78 would typically feature the builder's characteristic attention to detail in both construction quality and interior appointments. CNB yachts are known for their robust build quality, making them suitable for serious blue-water cruising and potential ocean crossings. The size suggests generous interior volume for extended living aboard, while the CNB pedigree implies sailing characteristics that won't disappoint performance-minded owners. Given CNB's market positioning, this yacht likely appeals to sailors who demand both seaworthiness and sophistication, representing a significant investment in long-range cruising capability without sacrificing the finer aspects of yacht ownership.

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
 23.55
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
 40.53
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
 1.7
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. 11.44
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
