Design and Construction
The Oceanis 351 draws on a solid fiberglass hull with a balsa-and-fiberglass sandwich deck, a construction approach Beneteau also applied to the Groupe Finot Oceanis. The deck sandwich lends stiffness and insulation aloft while keeping weight reasonable for a 35-foot cruiser. Below the waterline, the boat carries a bulb keel that the original review described as cutting an easy passage through the waves. With a fin keel and spade rudder, a 5-foot draft, and a displacement-to-length ratio near 185, the hull is a low-drag form derived from a racier sibling, giving the cruiser a light, responsive character beneath a voluminous deck.
Rig and Handling
The sloop rig is a masthead configuration with roller-furling main and genoa, which the period review praised as making for nice easy rigging. That furling setup suits short-handed sailing and anchors the boat's identity as a manageable coastal and mid-range cruiser. Under sail, test sailors found her easily reaching an impressive 7 knots in good winds and even 10 knots when cruising. The same light weight that aids speed becomes a drawback: when combined with a less powerful engine than some later Oceanis models, her performance drops in light winds.
Accommodations
Below decks the Oceanis 351 is laid out for life in the sun and pleasant anchoring, with an open saloon and tasteful, classic interior. The boat provides full 1.9-meter headroom and a U-shaped salon around which the galley runs the full length. Sleeping arrangements include a forward owner's cabin and two equal-size aft cabins, each with large hanging lockers. Natural light comes from four portholes in hull and deck plus a window above the sink. The cockpit adds an icebox under the table, and the stern platform gives easy access for bathing. The Beneteau is comfortable for long-distance trips, a claim supported by the generous sized cabin and open-plan social spaces.
Known Issues
Some owners report blistering problems on the Oceanis 351, particularly bubbling of the keel finish and rudder. This is the one documented cosmetic-to-structural concern surfacing in owner accounts and warrants close inspection of those two components on any candidate hull.
The Verdict
The Oceanis 351 is a Berret-designed cruiser that borrows a quick hull from the First 35.7 and wraps it in a roomy, sun-oriented deck. She sails efficiently in a breeze, feels secure in rough water, and offers a rare three-cabin layout with full headroom in her size class. The trade-off is soft performance in light air with the smaller engine, and a blistering record on keel and rudder that buyers should survey.
Pros
- Shared low-drag hull with the First 35.7 gives lively performance
- Full-length galley and U-shaped salon create open, social interior
- Two equal aft cabins plus forward owner's cabin with full 1.9m headroom
- Roller-furling main and genoa simplify short-handed rigging
- Good solid feel in rough seas and strong winds
Cons
- Light-air performance suffers with the less powerful engine
- Owner reports of keel-finish and rudder blistering
