About the Cs 44

Designed by renowned naval architect Tony Castro and built by Canadian Sailcraft, this rare 44-footer represents a fascinating piece of sailing history with only a single hull produced during its brief 1985-1986 production run. The boat showcases Castro's signature approach to performance cruising design, combining sophisticated engineering with practical sailing characteristics. The hull construction utilizes an advanced fiberglass and Kevlar composite with balsa core, delivering exceptional strength-to-weight ratio while maintaining the structural integrity needed for serious offshore work. With a displacement of 22,000 pounds and 9,000 pounds of ballast, the design achieves an impressive balance between stability and performance. The fin keel with spade rudder configuration provides excellent maneuverability and responsiveness. Her sail area of 970 square feet paired with the masthead sloop rig creates a powerful yet manageable sail plan suitable for both coastal cruising and offshore passages. The comfort ratio of 27.86 suggests a relatively stiff, performance-oriented vessel that prioritizes sailing ability over interior volume, while the capsize screening formula of 1.96 indicates good offshore seaworthiness. This unique vessel would appeal to experienced sailors seeking a rare, well-engineered yacht capable of serious cruising with spirited performance characteristics.

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
 78
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
 19.84
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
 40.91
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
 235.67
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
 27.86
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
 1.96
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. 7.89 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
 2.59
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. 1,693.44 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. 19.85
