Beneteau Oceanis 400 CC Sailboats for Sale

Layouts on the Used Market

The three-cabin arrangement is the more prevalent configuration you will encounter when shopping, offering a dedicated aft stateroom tucked beneath the center cockpit, a forward double cabin, and two heads. This layout suits couples with regular guests or families comfortable with the slightly compressed nature of the aft cabin, which runs low along the hull bottom — wide and accessible but distinctly snug overhead. Both staterooms are proper doubles, which distinguishes the 400 CC from many smaller center-cockpit designs where the aft cabin is an afterthought. Two-cabin variants exist on the market as well, offering somewhat different use of the aft section. The saloon itself is consistently spacious across all configurations, with a U-shaped settee and expandable table on the starboard side and the nav station and hanging locker to port — a sensible arrangement for offshore work.

Equipment and Common Upgrades

Used examples commonly arrive fitted with roller-furling headsails, autopilots, chartplotters, biminis, and cockpit showers — the baseline cruising kit that most owners added early in the boat's life. Teak decks, dinghy davits, and radar are also commonly fitted on boats with any offshore history. A furling main is frequently seen in place of the conventional-hoist mainsail; the original review noted that a conventional hoist higher-performance main might make sense for a dedicated sailor, so boats retaining or returning to that configuration are not unusual either.

Among the owner-installed upgrades, a dodger forward of the center cockpit is a frequent addition, providing meaningful protection for those moving between the cockpit and the foredeck. Watermakers, inverters, solar panels, and AIS transponders represent the generation of upgrades that owners added as they prepared for extended passages. A bow thruster appears on a meaningful minority of boats, particularly those used in Mediterranean marina environments where tight stern-to berths make it a practical investment. Heating systems, life rafts, EPIRBs, electric winches, and spinnakers — both symmetrical and asymmetric — are occasionally present and worth confirming against your actual offshore intentions.

What to Inspect

The hull is hand-laid solid fiberglass with an isophthalic gel coat intended to resist osmosis, and Beneteau offered a five-year structural and osmotic warranty at the time of production. That warranty is long expired on any boat you will encounter, so an independent osmotic survey is non-negotiable. Pay particular attention to the deck-to-hull joint, which is mechanically fastened every six inches and bedded in 3M 5200 — look for any signs of separation or water intrusion, particularly around chainplates and deck hardware.

The deck is balsa-cored sandwich construction, which means delamination from water ingress through hardware penetrations is a genuine concern on any boat of this vintage. Tap the deck thoroughly, and have any soft spots professionally assessed before committing. The anchor locker features a rectangular hawse pipe with 90-degree corners, which the original review flagged as potentially more likely to hang up ground tackle than an oval or rounded alternative — inspect for wear and verify the windlass switch is functional.

Steering is hydraulic, which provides smooth operation but demands its own inspection discipline; access for servicing is reasonable but the emergency steering hardware on tested examples was found to be loose-fitting, so confirm that the emergency tiller provision is solid and accessible. The Yanmar 60-horsepower diesel has an excellent reputation for longevity and parts availability, but verify service records and have the engine surveyed with particular attention to the stuffing box and transmission, both of which require access from the aft end of the engine space. If a generator has been installed in the space aft of the engine — the builder designated that location for one — confirm it has not compromised access to the engine itself or the stuffing box. Check that through-hulls are all labeled and operational; the review noted they were not labeled on the test boat, a deficiency that should be corrected before offshore use. The sugar-scoop stern and swim platform are popular gathering points; inspect the transom steps and any attached swim ladder hardware for corrosion and structural integrity.

Availability and Buyer's Takeaway

The Oceanis 400 CC is widely available across the United States and throughout the Mediterranean basin, with notable concentrations in France, Spain, Greece, and Italy reflecting both European origins and the charter and bluewater markets the boat historically served. The United Kingdom also carries a steady supply. Because the production run was relatively brief — mid- to late 1990s — the total pool of boats is finite, but not rare; patient buyers searching across brokerage networks in multiple regions will find options.

When evaluating a candidate boat, work through this checklist:

• Commission an independent survey with specific attention to osmosis and balsa-core delamination
• Confirm the deck-to-hull joint is fully bonded with no separation
• Inspect the hawse pipe and anchor locker for wear and proper chain lead
• Verify all through-hulls are labeled, operable, and free of corrosion
• Test the hydraulic steering and inspect the emergency tiller fitting for slop
• Review Yanmar engine service history and inspect stuffing box and transmission access
• Confirm any generator installation aft of the engine has not blocked access to the engine or stuffing box
• Evaluate the condition of teak decks if fitted — re-caulking or removal can be a significant expense
• Confirm safety equipment inventory: life raft certification, EPIRB registration, and flare expiry dates
• Test the autopilot, chartplotter, and any AIS installation under power before sea trial
