Norman 40
Description
The Norman 40 is a robust, long-distance cruising sailboat designed by the renowned Dutch naval architect G. van de Stadt in the 1970s and available as stock plans from Van de Stadt Design. Primarily built in steel or aluminum (with fiberglass options rare), it emphasizes seaworthiness, speed, and liveaboard comfort for one or two couples on extended voyages. The multi-chine or round-bilge hull provides strength and efficiency, while the fractional rig allows for versatile sail handling and reduced engine use. Features include a spacious deck saloon with panoramic windows for light and visibility (resistant to green water), a large 3.5m x 3.5m saloon, U-shaped galley, nav station, enclosed head with shower, and layouts for 2-3 cabins sleeping 4-6. Center cockpit enhances safety, and the design meets Lloyd's Register standards. Typical auxiliary is a Yanmar diesel (30-50 hp).
