About the Cardinal 46

Standing out as a substantial cruising yacht from the 1980s production era, this 46-footer represents Cardinal Yachts' commitment to building seaworthy vessels for serious sailors. The Cardinal 46 emerged during a period when manufacturers were focusing on creating boats that could handle both extended coastal passages and comfortable live-aboard cruising. Built with traditional construction methods and conservative design principles, the Cardinal 46 features the kind of robust build quality that earned the shipyard respect among blue-water sailors. Her full keel configuration and moderate displacement characteristics suggest a boat designed for stability and tracking ability rather than racing performance, making her well-suited for offshore passages and extended cruising adventures. The spacious interior layout typically accommodates long-term cruising with thoughtful storage solutions and livable spaces that don't sacrifice comfort for compactness. Her reputation centers around reliability and seaworthiness, traits that have made surviving examples popular among sailors seeking a proven platform for serious cruising endeavors. While Cardinal Yachts may not have achieved the widespread recognition of some contemporaries, the 46-footer demonstrates the builder's understanding of what long-distance cruisers actually need in a sailing vessel.

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
96
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
16.49
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
33.84
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
1.75
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. 8.27
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
2.4
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. 1.0
