About the Banner 41

Built between 1987 and 1993 by Danish builder Ib Hauge Nielsen, this performance-oriented 40-footer represents a collaboration between the renowned Judel/Vrolijk design team and Nielsen himself. With only 25 hulls produced during its six-year production run, the Banner 41 remains a relatively rare find on the used boat market. The yacht's impressive sail area to displacement ratio of 23.3 clearly marks it as a performance cruiser designed for sailors who prioritize speed without sacrificing offshore capability. Its fractional sloop rig and fin keel with spade rudder configuration delivers responsive handling and excellent upwind performance. The substantial ballast-to-displacement ratio of 43% provides reassuring stability for extended offshore passages. Construction features fiberglass with foam sandwich coring over a steel frame, offering both strength and weight savings. The low comfort ratio of 22.7 indicates a relatively narrow, performance-focused interior layout typical of boats from this era that prioritize sailing characteristics over living space. With a capsize screening formula of 1.87, the Banner 41 falls within acceptable parameters for offshore sailing, making it well-suited for serious coastal cruising and club racing. The Judel/Vrolijk pedigree ensures sophisticated hydrodynamics that reward skilled sailors with exceptional performance in a variety of conditions.

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
23.3
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
42.73
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
153.26
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
22.7
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
1.87
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. 7.68 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
4.15
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. 1,254.40 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. 23.31
