Designed by renowned French naval architect Yves-Marie Tanton and built by Taiwan's respected Ta Chiao yard starting in 1987, this 45-foot sailboat represents a thoughtful approach to offshore cruising. The Offshore 45 showcases Tanton's signature design philosophy of combining seaworthiness with comfortable living spaces for extended voyaging. The boat's most distinctive feature is its cat ketch rig with unstayed masts, offering excellent balance and ease of handling for short-handed crews. This configuration provides redundancy and allows for versatile sail combinations in varying conditions. The fin keel with rudder mounted on a protective skeg delivers good performance while maintaining directional stability, particularly valuable during long passages. With a displacement of nearly 26,000 pounds and substantial ballast ratio, the Offshore 45 prioritizes stability and comfort over racing performance. The moderate sail area-to-displacement ratio of 22.28 indicates this vessel excels in steady, predictable sailing rather than light-air speed. Her fiberglass construction and conservative design make her well-suited for serious cruising, including ocean passages. The boat's comfort ratio of 29.99 suggests motion characteristics favoring habitability, while the capsize screening value of 1.85 falls within acceptable ranges for offshore work, making this Tanton design a solid choice for adventurous cruising couples.
