About the BENETEAU 31
Shoal draft version: draft: 4.25' ballast: 2412 lbs.
The Beneteau 31 is a fractional sloop designed by Groupe Finot and built by Beneteau, with production records indicating a start year of 2002. This vessel features a displacement of 8933.0 lb and a beam of 11.08 ft, offering a balance of performance and comfort for its era.
- Best for:
- This boat is well-suited for coastal cruisers and weekend sailors who prioritize ease of handling and modern amenities, as evidenced by the high prevalence of bow thruster and electronics upgrades in the fleet.
- Bluewater capability:
- With a capsize ratio of 2.14 and a displacement of 8933.0 lb, the Beneteau 31 is primarily designed for coastal and inshore use rather than extended bluewater passages, though its robust hull form allows for protected offshore cruising with appropriate preparation.
- Comparables:
- Comparable vessels include other early-2000s European production cruisers such as the Jeanneau Sun Odyssey 319 or Dufour 328, which share similar fractional rigging, fin keel configurations, and target markets for active coastal cruising.
