About the Ct 41

Designed by the renowned William Garden and built by Taiwan's Ta Chiao Shipbuilding Company starting in 1972, this 41-foot ketch represents classic cruising yacht design from sailing's golden era. Garden's reputation for creating seaworthy, traditionally-styled vessels shines through in this substantial offshore cruiser. The CT 41's long keel configuration and generous displacement of 27,500 pounds create exceptional directional stability and sea-kindly motion, making her particularly well-suited for extended offshore passages and serious coastal cruising. Her masthead ketch rig provides versatile sail handling options, allowing crews to easily balance the boat in varying conditions while reducing the size of individual sails for manageable shorthanded sailing. With a comfort ratio of 43.82, this yacht prioritizes seaworthiness and interior volume over racing performance, typical of Garden's philosophy of creating homes that happen to sail rather than racing machines. The conservative capsize screening formula of 1.61 reflects her stable, confidence-inspiring nature in heavy weather. Ta Chiao's solid fiberglass construction earned respect during this period for quality and attention to detail. The CT 41 appeals to sailors seeking a traditional, well-mannered cruising yacht capable of handling serious offshore work while providing comfortable accommodations for extended voyaging.

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
 204
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
 13.97
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
 32.73
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
 357.63
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
 43.82
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
 1.61
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. 7.64 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
 1.17
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. 1,405.13 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. 13.96
