Beneteau Oceanis 350 Sailboats for Sale

Layouts on the Used Market

Two main interior arrangements circulate on the brokerage market. The more common configuration features a single aft cabin to starboard, placing the head in the aft quarter with a reasonably generous footprint, and dedicating a substantial cockpit locker to port. This layout suits a couple or small family and allows slightly better stowage throughout. A twin aft-cabin version — built only in France and frequently associated with the charter trade — divides the aft quarter into two smaller sleeping spaces, reducing both the starboard locker volume and the head to a more cramped arrangement. Stowage is even more restricted in the twin-cabin version, so buyers with serious cruising ambitions tend to prefer the single-aft-cabin boat when they can find one. The forecabin on both arrangements is a sleeping platform rather than a stand-up cabin, a tradeoff typical of the era's emphasis on aft accommodation. The nav station, sensibly placed opposite the galley and facing aft, is one of the interior's better-regarded features.

Equipment and Common Upgrades

Examples on the used market are typically fitted with solar panels, an autopilot, and a chartplotter — the baseline electrical additions that a generation of owners has layered onto the original specification. Heating systems, a bimini, and upgraded battery banks appear on a meaningful share of listings; lithium conversions and swim platform additions are seen often enough to count as a common owner upgrade rather than a rarity. A dodger, cockpit shower, dinghy davits, and short-handed sailing gear (additional winches, furling headsail upgrades, or an in-mast or in-boom furling main) surface more selectively and tend to mark boats that have been used for extended coastal or offshore cruising rather than harbour-based sailing. The original Frigiboat 12-volt refrigeration and Goiot roller furler may have been replaced on well-maintained examples; where they remain original, factor in the cost and difficulty of sourcing parts for French-manufactured fittings of this age.

What to Inspect

The electrical system is the area most consistently flagged by owners and surveyors. The original panel used electronic touch-button circuit breakers mounted on a printed circuit board, with heavy wiring soldered directly to terminal strips. Movement of the wires over years of sailing gradually fractures the small leads, causing intermittent failures. Many owners have rebuilt or replaced this panel entirely; confirm what is installed and inspect all wiring for tinning, sizing, and secure termination. Wire diameters were undersized from the factory and were not tinned, making voltage drop a real concern on older original looms.

The hull-to-deck joint deserves careful attention. The shoebox flange is riveted on approximately six-inch centres and through-bolted only at stanchion bases; leaks at stanchion bolt holes are a known weak point. Check every stanchion base for weeping or soft deck core. The deck is balsa-cored, and any long-standing moisture intrusion around hardware penetrations can mean widespread delamination — probe suspect areas and ask for a moisture survey.

Bulkheads fit into channels in the hull and cabin liner and are epoxied rather than glassed directly to the hull; on an older example these can begin to work slightly, particularly if the boat has seen offshore use. Look for cracking at bulkhead-to-liner junctions and check that the liner itself remains bonded throughout.

The keel deserves scrutiny on both variants. Iron ballast is used, with keel bolts screwed into steel inserts cast into the keel — lead would be preferable, and iron can corrode internally without obvious external signs. Inspect the keel-to-hull joint for rust staining and have the bolts checked on survey. On the shoal-draught wing-keel model, the winglets are bolted on and their attachment points should be examined for any signs of working or leakage. An owner note worth remembering: the wings can foul a second anchor rode, so passagemakers who anchor in tight quarters may prefer the deep-fin option.

The wraparound smoked skylights are a signature visual feature but a known source of leaks on older boats; check the sealant condition and any signs of interior water staining beneath them. Ventilation below decks is genuinely poor — just a single on-deck vent in the head and a forward hatch too small for sail bags — so look for owner-added Dorade vents or fans as a quality-of-life indicator. The anchor locker cover was described as flimsy with a large gap on original boats; assess its condition and whether a windlass has been fitted inside the compartment where it is protected from weather. Finally, the bow roller is too short for an articulated plough anchor without modification — a practical point for anyone intending to anchor regularly.

Availability and Buyer's Takeaway

The Oceanis 350 is most commonly found in France and the broader Mediterranean, reflecting its European production base and the chart-market roots of many of its hulls. A solid number also circulate in the United States, particularly on the East Coast near Beneteau's former South Carolina facility, and examples appear regularly in the Netherlands, Spain, and Scandinavia. It is a well-distributed boat with enough hulls in circulation that a patient buyer should find options on both sides of the Atlantic.

When evaluating any candidate, work through the following before proceeding to survey:

• Confirm layout variant (single vs twin aft cabin) and match it to your crew needs
• Verify the electrical panel has been rebuilt or replaced; inspect all wiring for tinning and sizing
• Commission a moisture survey of the balsa-cored deck, focusing on stanchion bases and all hardware penetrations
• Inspect keel bolts and the keel-to-hull joint for iron corrosion and rust staining; check winglet attachments on shoal-keel boats
• Check bulkhead-to-liner joints for working or cracking
• Test all deck hardware and hatches for leaks; examine skylight sealant
• Identify the roller furler and stove make; confirm parts are available or budget for replacement
• Assess ventilation below and note what the owner has done to improve it
• Confirm the anchor arrangement suits your anchor type; check bow roller reach
