About the BENETEAU 423
Also called OCEANIS 423. Shallow keel: 4.76'
The Beneteau 423 is a masthead sloop designed by Groupe Finot and built by Beneteau in 2002. With a displacement of 19500.0 lb and a beam of 12.93 ft, it represents a specific production year rather than a long-running series, offering a balance of performance and comfort typical of early 2000s European cruising yachts.
- Best for:
- This vessel suits coastal cruisers and those seeking a comfortable, well-equipped liveaboard or weekend cruiser, given the high prevalence of galley upgrades, watermakers, and canvas installations in the owner reports.
- Bluewater capability:
- With a capsize ratio of 1.93 and a displacement of 19500.0 lb, the boat is moderately stable for coastal passages, but owners frequently install watermakers, solar panels, and wind generators to support extended offshore or liveaboard use.
- Comparables:
- Comparable boats include the Beneteau 423's contemporaries like the Jeanneau Sun Odyssey 42 and the Bavaria 42, which share similar beam dimensions and masthead sloop rigs from the same era, though the 423 is distinguished by its specific Finot hull form and single-year production run.
