About the Sydney 40 Ac Sailboat

Designed by Murray Burns Dovell and built by Sydney Yachts starting in 1997, this performance-oriented 40-footer represents Australian yacht building at its finest. The composite construction delivers both strength and competitive weight, while the fractional sloop rig provides excellent sail handling characteristics for both racing and spirited cruising. With its fin keel and bulb configuration paired with a spade rudder, the Sydney 40 Ac offers responsive handling and impressive upwind performance. The moderate displacement of 12,680 pounds combined with 990 square feet of sail area creates a well-balanced platform that excels in both light and moderate conditions. The hull's 35.25-foot waterline length contributes to respectable theoretical hull speeds while maintaining manageable overall dimensions. The boat's design emphasizes performance without sacrificing seaworthiness, making it well-suited for coastal cruising, club racing, and offshore passages. The comfort ratio of 19 indicates a stiffer, more performance-oriented motion that serious sailors appreciate, while the capsize screening value suggests good stability characteristics for offshore work. This Sydney 40 variant appeals to experienced sailors seeking a capable boat that can handle diverse sailing conditions with confidence and style.
