About the Cartwright 40 Sailboat

Designed by Jerry Cartwright and built by Buzzards Bay Boats Inc. beginning in 1975, this substantial 40-footer represents classic American cruising yacht design from the mid-1970s. The fiberglass construction features a traditional long keel configuration that provides excellent directional stability and a smooth, comfortable motion in seaway conditions. With a displacement of 23,500 pounds and ballast of 10,500 pounds, this cutter-rigged vessel demonstrates the robust build quality typical of serious offshore cruising boats from this era. The long keel design, while not offering the quick tacking ability of modern fin keel boats, excels in tracking straight on long passages and provides reassuring steadiness in heavy weather conditions. The cutter rig configuration offers excellent sail handling flexibility, allowing crews to balance the boat effectively across varying wind conditions. With a comfort ratio of 43.2, the boat prioritizes seaworthiness and interior volume over pure performance, making it well-suited for extended coastal and offshore cruising rather than racing applications. The capsize screening formula of 1.57 indicates good stability characteristics for ocean passages, while the generous beam of 11.25 feet provides ample interior space for comfortable long-term cruising accommodations.
