About the Transpac 49 Sailboat

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.
