About the JEANNEAU 34.2
Called SUN ODYSSEY 34.2 in Europe and popular for the European/Med/Aegean charter trade. The STARDUST 342 and 343(depending on interior layout) are also based on this design.
The Jeanneau 34.2 is a masthead sloop designed by Jacques Fauroux and built by Jeanneau in 1999. With a displacement of 10253.0 lb and a beam of 10.75 ft, this vessel represents a specific production year rather than a long-running series, offering a balance of performance and comfort typical of late-90s European cruising designs.
- 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 Raymarine electronics and bimini installations in owner reports. Its moderate displacement and fin keel configuration make it accessible for couples or small families seeking a manageable package for inshore and nearshore passages.
- Bluewater capability:
- With a capsize ratio of 1.98 and a displacement of 10253.0 lb, the Jeanneau 34.2 is generally considered suitable for protected coastal waters and short offshore passages rather than extended bluewater expeditions. The fin keel and moderate ballast ratio suggest stability in moderate conditions but less reserve buoyancy for heavy ocean swells compared to heavier displacement designs.
- Comparables:
- Comparable vessels from the same era include the Beneteau First 34 and the O'Day 34, which share similar beam dimensions and displacement ranges. These boats are comparable due to their shared role as performance-oriented coastal cruisers with masthead sloop rigs and similar comfort ratios.
