The Dufour 40, designed by Umberto Felci and built by Dufour Yachts, is a performance-oriented cruiser produced in 2005. While the exact hull count is unspecified, this model represents a significant entry in the mid-2000s European market, known for its fractional sloop rig and lightweight construction.
- Best for:
- This boat is best suited for coastal cruisers and performance-minded sailors who prioritize speed and interior volume over heavy offshore ruggedness, as evidenced by the high frequency of bow thruster and electronics upgrades suggesting active, short-to-medium range usage.
- Bluewater capability:
- With a displacement of 17196.0 lb and a capsize ratio of 1.99, the Dufour 40 is generally considered suitable for coastal and nearshore cruising rather than extreme bluewater passages, as its lightweight hull and fin keel prioritize performance over heavy-weather stability.
- Comparables:
- Comparable boats include the Beneteau First 40 and Jeanneau Sun Odyssey 40.9, as they share similar production eras, fractional sloop rigs, and a design philosophy that favors light displacement and high sail area-to-displacement ratios for enhanced planing capabilities.
