About the Transpac 49

Designed by George Duke and built by Transpacific Marine in Taiwan from 1976 to 2004, this substantial ketch represents a classic approach to offshore cruising. With its masthead ketch rig and conservative 43.67 comfort ratio, the Transpac 49 was conceived for serious bluewater passage making, offering the redundancy and sail handling flexibility that long-distance cruisers prize. The boat's solid fiberglass construction and traditional fin keel with skeg-mounted rudder configuration provides excellent directional stability and protection for the steering system—critical features for extended ocean voyaging. At 39,000 pounds displacement with 12,000 pounds of ballast, she carries herself with authority through heavy seas while maintaining predictable handling characteristics. Her generous 13.58-foot beam creates substantial interior volume, while the 6-foot draft strikes a reasonable balance between stability and harbor accessibility. The masthead ketch rig, with 1,050 square feet of sail area, allows for versatile sail combinations and manageable canvas reduction in deteriorating conditions. With a capsize screening value of 1.61 and hull speed of 8.51 knots, the Transpac 49 demonstrates the seakindly characteristics and moderate performance expectations typical of her era's cruising designs. The 120-horsepower engine provides adequate auxiliary power for maneuvering and motorsailing when conditions demand.

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
98
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
14.67
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
30.77
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
265.42
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
43.67
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. 8.51 kn
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. 1,956.93 pounds/inch
