Designed by John Brandlmayr and built by Spencer Boats Ltd. from 1965 to 1983, this classic 42-footer represents traditional offshore cruising design from sailing's golden era. With only 26 hulls produced during its 18-year production run, the Spencer 42 remains a relatively rare find among vintage fiberglass cruisers. The boat's conservative design philosophy shines through its robust construction and seaworthy proportions. The full keel configuration provides exceptional tracking ability and moderate helm balance, while the generous 8,000-pound ballast ensures stiff, predictable sailing characteristics. At 19,000 pounds displacement, this masthead sloop offers the substantial feel and motion comfort that serious cruising sailors appreciate during extended passages. With a comfort ratio of 34.39, the Spencer 42 delivers the steady, forgiving motion that makes offshore sailing less fatiguing for crew. The conservative capsize screening formula of 1.7 reflects the design's emphasis on stability over ultimate performance. While the sail area to displacement ratio of 17.03 indicates moderate power in light air, this boat truly comes alive in stronger conditions where its sea-kindly nature becomes apparent. This Spencer represents an excellent choice for sailors seeking a proven offshore cruiser with traditional sailing qualities and the character that comes with owning a piece of sailing history.
