Beneteau Oceanis 351 (1997 Version) Sailboats for Sale

The 351 came at the height of the era when beamy production cruisers were conquering boat shows, and Beneteau leaned into that fully. Her maximum beam is carried well aft, inflating the saloon and aft-cabin space to a degree that still impresses today. Charter companies recognised this immediately and snapped up hulls in quantity, meaning a significant share of used examples have led hard lives with rotating crews. High construction standards mean many have survived that treatment well, but a full survey is strongly recommended before purchase.

Layouts on the Used Market

Two distinct accommodation plans circulate on the brokerage market. The three-cabin version, by far the more commonly seen option, places two equal aft cabins flanking the companionway ladder with a forward V-berth owner's cabin up front. All three double cabins are genuinely spacious, with berths running to around two metres in length and enough floor space to dress in comfort. The heads compartment in this layout is slightly smaller than the two-cabin version and shares the space with a wet locker rather than a full separate shower stall. The saloon in both layouts follows a dinette arrangement with an oval table to port and a linear galley running to starboard — attractive at anchor and in marinas, though less convenient for cooking under sail.

The two-cabin variant, less often encountered but worth seeking out if offshore sailing is your priority, swaps the second aft cabin for a deeper cockpit locker to starboard and a more generous heads compartment with a separate shower. The forecabin in both layouts is a comfortable V-berth. Navigation station placement and chart table size are identical across configurations.

Equipment and Common Upgrades

Used examples come to market with equipment reflecting the full range of owner investment. The original Z-Spars masthead rig is straightforward and often intact, though running rigging should be assumed to need renewal. Roller-furling on the genoa was standard from the factory, and many boats also carry a furling mainsail — either the original in-mast arrangement or a later retrofit. The two-cockpit-winch arrangement that was standard equipment is widely considered inadequate for comfortable shorthanded sailing, and owners frequently add a third or fourth winch as a priority upgrade.

Autopilots are a common addition, as is the fit-out of a proper anchor windlass with a bow roller upgrade to a twin-roller stemhead fitting. Engine replacement is not unusual on older examples — the original Volvo Penta MD2030 is a capable unit but extended years of service have prompted many owners to fit a newer engine, often paired with a fixed three-blade propeller replacing the original folding two-blade that was regarded as marginal for close-quarters maneuvering. Battery bank renewals, new navigation electronics, and VHF upgrades are routine finds. Boats that have passed through charter fleets often had cockpit cushions, bimini frames, and extra fender stowage fitted as standard.

What to Inspect

The 351 has a well-documented set of structural and cosmetic areas that reward close attention from a qualified surveyor.

The most significant structural concern is the internal hull moulding — a tray bonded into the inside of the hull with paste. This moulding is notorious for coming away from the hull, and if left unaddressed the hull will flex and cracks will appear both on the hull exterior and on deck. Check for cracks and gaps around the edges of the moulding in the bilge below the saloon and forecabin sole. The fix, if needed, is a proper glassing-back with tabbing, cloth, and resin, but the condition of this bond is central to whether a given hull is sound.

Deck delamination is another frequent finding — the balsa core used in the sandwich deck construction has a tendency to shrink and decay with age, causing the deck to flex underfoot. Look for soft spots throughout, particularly around chainplates, stanchion bases, and hatches. Stanchion backing pads are rarely adequate and frequently allow water ingress unless they have been reinforced.

The keel area deserves careful attention — check for cracks in the moulding around the keel studs. The bedding compound between hull and keel has a finite lifespan and tends to break down after around two decades, with older examples likely overdue for re-bedding. There have been reports of keel bolt distortion requiring new bolts and larger backing pads; if the keel shows any signs of movement or weeping rust streaks at the stub, treat this as a serious item.

Separately, blistering in the keel finish and on the rudder has been reported and should be inspected for osmotic activity. Hull blistering is less prevalent on the 351 than on some contemporaries, but any boat of this age with an unattended antifoul history deserves a proper osmosis assessment.

Below decks, the seacocks should be checked carefully around the skin fittings, where the bonding paste in the relieved areas of the internal moulding has frequently been found detached — a subtle red flag that can indicate previous grounding or developing structural movement. The cooling system on the Volvo Penta MD2030 has a tendency to clog up, so a full service history and a compression test are worthwhile on any boat retaining the original engine. Acrylic windows and portlight seals, window bedding compound, and grabrail sealant will all be at or past their service life on older hulls, and cockpit teak inlay on many boats is a ply veneer now at the point of replacement.

Availability and Buyer's Takeaway

The Oceanis 351 is widely available across Northern Europe — the UK, France, the Netherlands, and Germany in particular — reflecting the model's strong charter and coastal-cruising following during its production years. Examples also circulate regularly in the Mediterranean and on the eastern seaboard of North America, and the model's popularity means a patient search rarely goes unrewarded.

This is a good-value family cruiser that rewards buyers who invest in a thorough survey and approach any purchase with eyes open to the predictable areas of age-related wear. A hull in good structural order — with the internal moulding intact, decks solid, and keel area clean — offers strong return on investment as a coastal and channel-crossing boat for a family or a couple who value space over pure sailing performance.

Pre-purchase checklist:

• Instruct a surveyor experienced with fibreglass 1990s production boats — specify the internal hull moulding bond as a priority
• Probe all deck surfaces for softness, paying close attention around stanchion bases, chainplates, and hatch frames
• Inspect keel stub inside and out for cracks, weeping rust, and bedding compound condition
• Check seacocks and the bonding paste at every skin fitting
• Test or service the Volvo Penta MD2030 cooling system if the original engine is in place; request all maintenance records
• Confirm winch count and assess whether additional winches are needed for your intended use
• Assess portlights, windows, and grabrail bedding for leaks
• Clarify whether the mainsail system is in-mast furling or slab-reefed and inspect accordingly
• Verify the transom cockpit seat is properly secured
• Budget for running rigging replacement regardless of apparent condition
