About the Ross 40 Tm Sailboat

Designed by Murray Ross and first launched in 1981, this 40-footer represents a thoughtful approach to performance cruising from the early 1980s. The Ross 40 Tm features a modern fin keel and spade rudder configuration that delivers responsive handling and good upwind performance, while her fractional sloop rig provides excellent sail control and versatility across varying conditions. With a displacement of 10,600 pounds and 4,500 pounds of ballast, this fiberglass yacht strikes a balanced compromise between stability and performance. Her sail area to displacement ratio of 26.98 indicates spirited sailing ability without being overly aggressive, making her well-suited for both coastal cruising and offshore passages. The comfort ratio of 16.15 suggests she'll provide a relatively easy motion at sea, while the capsize screening value of 2.19 falls within acceptable parameters for blue water sailing. The Ross 40 Tm's 35.50-foot waterline length contributes to her theoretical hull speed of nearly 8 knots, while her 12-foot beam provides adequate interior volume and initial stability. This design appeals to sailors seeking a capable cruising yacht that doesn't sacrifice sailing performance for comfort, making her suitable for extended coastal cruising and select offshore adventures.
