About the Slocum 43 Sailboat

Built during the 1980s by Cruising Yachts International and Formosa, this Stan Hundtingford-designed cruiser represents solid bluewater sailing capabilities wrapped in traditional aesthetics. With only 60 hulls produced between 1981 and 1990, the Slocum 43 has earned a reputation as a capable offshore passage-maker among serious cruising sailors. The cutter rig configuration provides excellent sail handling options and heavy weather versatility, while the fin keel with rudder on skeg offers a good balance of performance and directional stability. At 28,104 pounds displacement with 9,000 pounds of ballast, she carries the weight and stability needed for extended ocean passages. The comfort ratio of 38.02 indicates a motion that favors seaworthiness over speed, making her well-suited for long-distance cruising rather than racing. Her fiberglass construction and robust scantlings reflect the era's emphasis on strength and durability. The relatively low sail area to displacement ratio suggests conservative sail power, prioritizing safety and ease of handling over pure performance. This makes the Slocum 43 an attractive choice for couples or small crews planning serious cruising adventures, particularly those venturing offshore where reliability trumps speed.
