The Dufour 310 Grand Large is a fractional sloop designed by Umberto Felci and built by Dufour, with production records indicating a build year of 2014. While the exact total hull count is unspecified in the authoritative data, the model is characterized by a displacement of 10891.0 lb and a beam of 10.86 ft.
- Best for:
- This vessel suits coastal cruisers and weekend sailors who prioritize interior volume and modern amenities over heavy offshore endurance, evidenced by the high prevalence of solar panel (40), watermaker (38), and davit (39) installations.
- Bluewater capability:
- With a capsize ratio of 1.96 and a comfort ratio of 23.81, the boat is designed for coastal cruising rather than extreme bluewater passage-making, though owner modifications like watermakers suggest some offshore preparedness.
- Comparables:
- Comparable boats include other Dufour models from the same era and similarly sized fractional sloops with fin keels, as they share the 31.73 ft LOA and similar performance ratios like the 17.73 SA/D ratio.
