Swan 431

Designed by the legendary Sparkman & Stephens and built by Finland's prestigious Nautor shipyard, this classic Swan represents the pinnacle of 1970s cruising yacht design. With only 32 hulls produced between 1976 and 1978, the Swan 431 embodies the exclusivity and craftsmanship that made the Swan brand synonymous with quality bluewater cruising. The yacht's impressive 26,500-pound displacement and substantial 11,900-pound ballast create exceptional stability and seaworthiness, while the moderate comfort ratio of 35.55 indicates good motion characteristics in rough seas. Her fin keel with rudder on skeg configuration provides excellent directional stability and balanced helm feel, making her particularly well-suited for offshore passages and serious coastal cruising. The masthead sloop rig with 896 square feet of sail area delivers respectable performance while remaining manageable for shorthanded sailing. Her fiberglass construction ensures durability, and the favorable capsize screening formula of 1.8 confirms her blue water credentials. With a theoretical hull speed of 7.74 knots and well-balanced sail area to displacement ratio, the Swan 431 offers that perfect blend of comfort, safety, and performance that serious cruising sailors seek in a classic yacht.
