The Beneteau 311 is a fractional sloop designed by Groupe Finot and built by Beneteau, with production records indicating a single build year of 1998. This vessel represents a specific era of Beneteau's performance-oriented cruising line, characterized by a displacement of 7716.0 lb and a beam of 10.5 ft.
- Best for:
- This boat is well-suited for coastal cruisers and active weekend sailors who prioritize responsive handling and interior volume over heavy bluewater displacement. Its fractional rig and moderate comfort ratio of 17.49 suggest it performs best in protected waters and shorter passages rather than extended offshore expeditions.
- Bluewater capability:
- With a capsize ratio of 2.13 and a displacement/length ratio of 146.17, the Beneteau 311 is designed for coastal and inshore cruising rather than serious bluewater passage-making. Its relatively light displacement and fin keel configuration prioritize speed and maneuverability in moderate conditions over heavy-weather stability.
- Comparables:
- Comparable vessels include the Beneteau First 31 and the Jeanneau Sun Odyssey 31, which share similar fractional sloop rigs and target the same market of performance-minded coastal cruisers. These boats offer similar beam and displacement characteristics, providing a benchmark for handling and interior layout in the 30-32 foot range.
