Designed by Jean-François Delvoye and built by the respected French yard Boréal Yachts since 2017, this 47-footer exemplifies modern aluminum expedition cruising design. The robust aluminum construction delivers exceptional durability for long-distance voyaging, while the cutter rig configuration provides versatile sail handling options in varying conditions. At 47.74 feet overall with a displacement of 22,686 pounds, this yacht strikes an excellent balance between interior volume and seaworthiness. The keel-centerboard configuration with spade rudder offers tactical advantages for shallow-water exploration while maintaining deep-water stability. With substantial ballast at 8,378 pounds and a conservative capsize screening formula of 2, the design prioritizes safety margins essential for offshore passages. The sail area of 1,076.39 square feet paired with the SA/Displacement ratio of 21.57 indicates moderate power suitable for comfortable cruising rather than aggressive performance. A comfort ratio of 25.17 suggests motion characteristics that favor habitability over speed, making extended passages more pleasant for the crew. Boréal's reputation for building go-anywhere cruising yachts shines through in this design, which targets serious cruisers seeking a capable platform for extended offshore adventures, polar exploration, or circumnavigation. The 50-horsepower engine provides reliable auxiliary power for challenging conditions or tight marina work.
