About the Aurora 40 Sailboat

Built by Canadian manufacturer Hinterhoeller Yachts beginning in 1976, this 40-footer represents a thoughtful approach to blue water cruising design. With only four hulls ever constructed, the Aurora 40 stands as a rare find in today's used boat market, designed by the collaborative team of Mark Ellis and Hinterhoeller. The boat's substantial 22,500-pound displacement and deep 9.16-foot draft signal serious offshore capability, while the generous ballast ratio of nearly 33% provides excellent stability for ocean passages. Her cutter rig configuration offers versatility in sail handling, particularly valuable when sailing shorthanded or in challenging conditions. The fiberglass construction reflects the era's emphasis on durability over weight savings. Performance characteristics reveal a cruiser optimized for comfort rather than speed, with a moderate sail area to displacement ratio of 17.78 and a respectable comfort ratio of 35.18. The capsize screening formula of 1.77 falls well within accepted parameters for offshore sailing, indicating good initial stability. Her theoretical hull speed of 7.5 knots suggests reliable passage-making capability. This Aurora 40 would appeal to sailors seeking a proven offshore cruiser with traditional design values, though potential buyers should consider the challenges of parts availability given the limited production run.
