Beneteau Oceanis 350 Information, Review, Specs

Sailing Performance & Handling

The Oceanis 350 was never intended to be a regatta winner; rather, it was designed for predictable, upright cruising. Most 350s were equipped with a masthead sloop rig and a choice of two keel configurations: a deep fin or a shallow-draft wing keel. The wing keel, which was particularly popular in North American markets and the Caribbean, allows the boat to explore shallow anchorages that would be off-limits to more performance-oriented hulls.

Handling is characterized by a high degree of initial stability, though the boat can feel under-canvased in light air due to its relatively modest sail area-to-displacement ratio and high freeboard. However, once the wind reaches 12–15 knots, the Briand-designed hull finds its groove, tracking well with a balanced helm. The spade rudder provides responsive steering, though the boat’s windward performance is hampered by its wide beam and cruising-oriented hull shape compared to its siblings in the First range. Owners frequently report that while it is not a "pointing machine," it is a capable and forgiving coastal cruiser that manages offshore chop with a surprising degree of dryness for its size.

Interior Comfort & Variations

The interior of the Oceanis 350 was revolutionary for the 1980s, primarily due to the inclusion of large, panoramic plexiglass windows on the coachroof that flooded the salon with natural light. This "sunlight" concept became the hallmark of the early Oceanis range. The layout was offered in two primary configurations: a three-cabin version often utilized in charter fleets and a more comfortable two-cabin "owner’s" version.

In the owner’s version, the boat features a massive aft cabin that spans nearly the entire beam, a feature rarely seen in 35-footers of that era. The galley is typically L-shaped and situated to port, providing ample counter space for extended cruising. The use of light-colored woods and the lack of dark corners created an "apartment-like" feel that appealed to a new generation of recreational sailors. The three-cabin variant, while tighter in the aft quarters, remains a favorite for families, providing three distinct sleeping areas and a central salon that can still accommodate a crowd for dinner.

The 350 shares its DNA with its contemporaries, the Oceanis 320 and the larger Oceanis 390. While the 320 was often seen as too compact for serious cruising and the 390 felt massive for a couple, the 350 hit the "sweet spot" of the range, offering a balance of maneuverability and living space that has sustained its popularity for decades.

Known Issues & Buyer’s Checklist

Prospective buyers should approach an Oceanis 350 with a specific technical checklist, as several age-related issues are common across this generation of Beneteau builds:

• Plexiglass Window Crazing and Leaks: The signature panoramic windows are the 350’s greatest aesthetic asset and its biggest maintenance headache. The original acrylic panels are prone to crazing and, more importantly, leaking as the sealant dries out over thirty years. Re-bedding these windows is a labor-intensive specialized task.
• Grid Bonding: Beneteau utilized an internal fiberglass grid (the "liner") bonded to the hull to provide structural rigidity. Buyers should have a surveyor check for "hollow" sounds or signs of delamination where the grid meets the hull, particularly near the keel bolts, which could indicate a hard grounding in the boat's past.
• Mast Step and Compression: Some early models have shown signs of compression at the mast step. Inspect the area around the base of the mast and the supporting internal pillar for signs of sagging or hairline fractures in the gelcoat.
• Osmotic Blistering: Like many boats from the late 80s, the Oceanis 350 can be prone to osmotic blistering if the hull has not been protected with an epoxy barrier coat. A moisture meter test during haul-out is essential.
• Rudder Bearings: The spade rudder design can develop "slop" or play in the bearings over time. While not a structural failure, it can lead to annoying vibrations and less precise steering.

Community & Resources

Owners of the Oceanis 350 are supported by a robust network of enthusiasts. The Beneteau Owners Association serves as the primary hub for technical documentation, including original wiring diagrams and plumbing layouts. Additionally, the Philippe Briand Design archives occasionally provide insight into the original naval architecture for those looking to perform authentic restorations.

The Verdict

The Beneteau Oceanis 350 is a quintessential coastal cruiser that prioritize volume and light over raw speed. While it requires a vigilant owner to manage its aging deck windows and hull liner, it offers a level of interior comfort that remains competitive with many modern designs.

Pros:

• Exceptional interior volume and natural light for a 35-foot boat.
• Choice of shallow-draft wing keel for versatile cruising.
• Reliable, predictable handling in moderate to heavy conditions.
• Affordable entry point into the "Beneteau lifestyle."

Cons:

• Large coachroof windows are notorious for leaking and crazing.
• Average performance in light air and when sailing close-hauled.
• Potential for complex repairs if the internal hull grid has delaminated.
