About the Tradewinds 55 Sailboat

Designed by renowned naval architect Bruce King and built by Tradewinds Marine beginning in 1980, this 55-footer represents a rare find in today's market with only three hulls ever constructed. The fiberglass construction features a fin keel configuration that delivers excellent windward performance while maintaining manageable draft for accessing diverse cruising grounds. King's design philosophy shines through in the boat's balanced proportions and seaworthy characteristics. The cutter rig provides exceptional versatility for varying wind conditions, allowing sailors to reduce sail area progressively while maintaining proper balance. With a displacement of 38,000 pounds and 16,000 pounds of ballast, this yacht offers the stability and sea-kindly motion essential for serious offshore cruising. The impressive comfort ratio of 41.99 indicates a vessel built for extended passages, while the conservative capsize screening formula of 1.67 reflects its blue-water credentials. The generous beam of 14 feet creates spacious accommodations below while contributing to initial stability. This combination of Bruce King's proven design expertise and robust construction makes the Tradewinds 55 particularly well-suited for offshore cruising and long-distance voyaging, though its rarity means finding one requires patience and often represents a unique opportunity for the discerning sailor.
