About the Inferno 26

Designed by Swedish naval architect Håkan Södergren and first launched in 1984, the Inferno 26 represents a compelling blend of performance-oriented sailing and weekend cruising capability. This 26-foot fractional sloop showcases classic Scandinavian design principles with its fin keel and spade rudder configuration, delivering responsive handling and solid upwind performance that reflects its racing pedigree. With a displacement of 4,078 pounds and 1,653 pounds of ballast, the Inferno 26 strikes an appealing balance between stability and spirited performance. The boat's sail area-to-displacement ratio of 21.81 indicates excellent light-air performance while maintaining control in stronger conditions. Its moderate comfort ratio of 16.49 suggests this yacht leans toward the performance end of the spectrum while still offering reasonable accommodations for coastal cruising and weekend adventures. The fiberglass construction ensures durability and relatively low maintenance, making it an attractive option for sailors seeking both competitive racing potential and recreational sailing enjoyment. The Inferno 26's design characteristics make it particularly well-suited for coastal sailing, club racing, and spirited day sailing, where its responsive nature and good sailing manners can be fully appreciated by crews looking for engaging performance on the water.

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
 21.81
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
 40.53
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
 163.95
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
 16.49
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
 2.04
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. 6.33 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
 3.78
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. 648.89 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. 21.79
