Design and Hull Form
Berret Racoupeau gave the Oceanis 55 a hull with hard chines that carry well forward of the mast. On the water, those chines perform a specific job: when puffs arrive and the boat heels, hard chines that carry aft dig in to keep the boat tracking straight and upright rather than rounding up. The beam — just over 16 feet at its widest — is maintained aft, giving the hull both stability and the volume needed to support a genuinely spacious interior. Three keel options were offered at launch: a shoal-draft 4-foot-9-inch foil for Bahamas-style cruising, a standard 5-foot-11-inch keel, and a deep 7-foot-3-inch racing-oriented option, each carrying different ballast weights. Twin rudders — a first for the Oceanis line — provide tactile feedback at both helm stations and allow the boat to back cleanly to either side under power alone.
The mast was shifted aft relative to earlier Oceanis designs, a deliberate choice that opens a full third of the boat's length to the cockpit while also reconfiguring the sail plan. The result is a larger headsail and a slightly smaller main — two sails of roughly equal area that balance each other naturally and reduce the brute-force demands on the crew.
Rig and Sailing Character
Under sail, the Oceanis 55 is a boat of two personalities divided by wind speed. In conditions under 10 knots the boat can feel lifeless in any seaway, with a fixed three-bladed propeller adding drag that blunts performance further. In 7 knots on a close reach the Yachting World test recorded 4.5 knots — acceptable for a 16-ton displacement cruiser but not exciting. The transformation comes with more breeze. In 12 to 14 knots true the boat consistently clocked 7.5 knots upwind, and close-reaching at 60 degrees apparent she pushed past 9 knots. In the original Cruising World sea trial, close-reaching at 7 and 8 knots alongside Bahamas-bound Lagoon catamarans earned the boat its reputation as a competitive monohull in a world increasingly dominated by cruising multihulls.
A Code Zero or cruising chute makes an outsized difference. Yachting World observed that a Code 0 made an astonishing difference as soon as the boat found her chine and the power came on, with reaching numbers jumping markedly. The optional inner forestay and self-tending staysail expand the sail inventory further, and there is a bail on the anchor roller for flying a code zero or cruising chute without a dedicated furler. In stronger air, the boat's beamy, twin-rudder character rewards early reefing: beamy cruising boats with twin rudders generally need to be treated with caution and depowered early, a point worth keeping in mind for less experienced crews who might misread the apparent stiffness as an invitation to carry sail.
Cockpit and Deck Layout
Beneteau redesigned the cockpit arrangement specifically to create more exterior living space than the outgoing Oceanis 54 could manage. Moving the mainsheet arch and companionway forward freed up room for L-shaped cockpit benches and a companionway at a gentle 45 degrees, with the result being a space easily capable of seating eight around the folding teak table. Two full-length cushioned benches flank the table, two further sunbeds sit forward of the arch on either side of the companionway, and the electric primary winches located just inboard of each helm put tacking within reach of a single helmsman without crew on the rail.
The electrically lowered swim platform is one of the more practical touches: raised, it folds to create a cockpit-wide helm seat; lowered at anchor, it becomes a terrace at sea level. That said, the lowered platform creates a step at the aft end of the cockpit that tripped up the reviewer just about every time he crossed it — a minor but persistent ergonomic catch. The arrangement of running rigging at the two helm winches also has its limitations: the mainsheet only leads to the port winch, with no option for sheeting to either side, which matters when you want to dump the main quickly in a gust.
Accommodations
Below, the 16-plus feet of beam carried aft from the main bulkhead creates volume that would not be out of place on a 60-foot traditional design. The layout choices run from three cabins and two heads to five cabins and four heads — the five-cabin version uses a Pullman berth in place of a second aft head. There is also a forward crew cabin with its own head and vanity, useful for charter configurations or professional crew. The master suite features an island berth surrounded by storage and hanging lockers, while a cleverly designed chest of drawers with sliding top creates an office space alongside the main cabin.
Lighting below is generous: eight large windows and flush coachroof hatches prevent the cave-like feel that plagues many heavily-built cruisers of this size. Yachting World's tester found the interior capacious and well-lit in the three-cabin/two-heads layout, though the area between the saloon, nav station, and galley was described as large enough to conduct tango classes — space that reads as waste to some buyers but as breathable airflow to others on a hot anchorage.
The galley deserves a candid note: this is not large for a 55-foot boat, and the five-cabin configuration tightens it further. Traditional sailors will appreciate the presence of a dedicated chart table, an item the smaller Oceanis models eliminated, and the modular saloon with rotating chart table seat allows flexible use of the navigation area.
Known Issues and Considerations
Performance in light air is the recurring theme in independent testing. A fixed three-bladed propeller was standard on some configurations, and both test reviews noted that a fixed prop didn't help the boat's already modest light-air numbers. Buyers fitting the boat for extended passages should budget for a folding or feathering propeller at commissioning. The cockpit rope management also draws comment: with halyards, sheets, and reefing lines all converging at the two helm winches, the working area quickly becomes a tangled mess of lines, and the dedicated rope bins overflow readily during foresail changes.
The interior finish is limited in its timber choices — alpi mahogany veneer is the only option — so the personalisation Beneteau markets largely comes through upholstery selection rather than structural joinery variation. Noise under engine was noted as higher than expected by Yachting World's tester, worth considering for owners who motor in confined waterways regularly.
Twin rudder dynamics also merit attention. While the system gives excellent feedback and makes backing straightforward, the stiffness that comes with a beamy, twin-rudder hull can mask the need to reef. The boat had apparently sailed in 30 knots with just one reef — proving structural stiffness, but not necessarily prudent seamanship for a loaded cruiser.
Refitting and Upgrading
The Oceanis 55's optional equipment list is extensive, and the boat's systems architecture was clearly designed to accommodate it. The gap between a base boat and a fully equipped passage-maker is wide, as the lengthy options list spanning electronics, rig, and interior finish makes plain. Long-distance cruisers will find the option for extra tankage increasing water and fuel to 1,000 and 600 litres respectively particularly relevant for offshore passages. The 75-horsepower Yanmar saildrive is a proven package at this displacement, pushing the boat to just over 9 knots at maximum power and offering nearly on-a-dime stopping from cruising speed.
The optional Dock & Go joystick and pod-drive system makes marina maneuvering significantly more manageable, and the twin-rudder baseline already gives the boat good reversing behavior without it. Electric primary winches fitted at the factory simplify shorthanded passages, and the optional inner forestay and self-tending staysail represent arguably the most useful sailing upgrade for couples heading offshore.
The Verdict
The Beneteau Oceanis 55 is a well-resolved bluewater cruiser that rewards honest evaluation. It is not a light-air racer, and buyers expecting crisp performance below 10 knots will be disappointed unless they invest in a large reaching sail. But in the conditions the boat was designed for — Force 3 and above, passages of several days, crews of two to six — it is a genuinely capable, comfortable, and confidence-inspiring yacht. The twin-rudder sailing feel, the thoughtfully engineered cockpit, and the sheer accommodation volume set it apart from most production competitors of similar length.
Pros
- Hard-chine hull with twin rudders delivers strong upwind and close-reaching performance in moderate to fresh breeze

- Three keel options allow genuine draft flexibility from shoal anchorages to bluewater passages
- Inboard electric primary winches enable true single-handed sail handling
- Accommodation layouts from three to five cabins suit both private owners and charter configurations
- Electrically lowered swim platform doubles as a full-width helm seat underway
Cons
- Light-air performance is sluggish without a Code Zero or cruising chute; a fixed prop compounds the problem
