The 51.1 was explicitly designed for a couple to handle, with occasional guests aboard. Its engineering brief favors interior volume and easy shorthanded sailing without abandoning performance.
Design and Construction
The hull is the headline feature. Roughly a third of its length is stepped or chined, and on the 51.1 those chines run literally from bow to stern rather than fading out amidships. Beneteau’s literature traces this distinctive form to the Juan Kouyoumdjian-designed Rambler 88, an all-carbon ocean racer. The theory behind carrying the chine for the full length is to provide a finer entry, reduce wetted surface, and increase buoyancy when the boat heels.
The same hull serves all three market versions—First, Comfort, and Easy—with differences confined to their interiors and rigging. It measures 52 feet 4 inches overall, with a 15-foot 9-inch beam, and weighs just over 30,700 pounds. The standard iron keel draws 7 feet 7 inches.
Construction is vacuum-infused fiberglass, with balsa coring in both the hull and deck. A vinylester resin layer beneath the gelcoat guards against osmotic blistering. Lifelines were raised a few inches compared with the predecessor. Wide side decks and lower shrouds brought in to the cabin top allow crew to move forward without ducking under the rigging.
Rig, Performance, and Handling
The standard boat is set up as a forgiving daysailer-cruiser, with in-mast furling, a self-tacking jib, and all halyards and sheets led to one winch at each helm. The Easy version retains the self-tacker, while the Comfort version adds an internal D1 lower shroud. The First version carries an additional 35 percent of sail area on either a carbon or aluminum spar, along with upgraded winches, deck hardware, and composite wheels.
A 9-foot 2-inch performance keel carries a lead bulb, reducing weight and hydrodynamic drag. On the water, the test boat accelerated to nearly 5 knots on a beam reach in 6.4 knots of apparent wind. In just over 10 knots of breeze, it held 7.4 knots upwind under main and self-tacking jib, then maintained that pace off the wind with a Code 0 set from the composite bowsprit. The twin rudders allowed it to spin quite fast through tacks.
The cockpit layout supports active sailing. Crew at the winches face forward and can see the sails, while hinged foot braces at the helms fold away to avoid becoming toe-stubbers when the boat isn’t heeling.
Accommodations
The number of possible configurations is remarkable. Four interior plans, five rigging plans, three keel types, and 150 options produce more than 700 combinations. Layouts offer three, four, or five cabins and as many as four heads.
In the three-cabin layouts, the forward owner’s cabin has a 160-by-205-centimeter centerline island berth with walk-around access, an en-suite shower, and a separate toilet. The galley, arranged in either a U or C shape to port, includes soft-close drawers, an Eno two-burner stove, Vitrifrigo drawer refrigeration, and an oven.
In the saloon, a large table and U-shaped seating can accommodate as many as 14 people. The navigation station doubles as a desk, with a pop-up seat and leg rest. Multiple overhead hatches and hull ports bring in plenty of light, and the interior is available in a new “brushed oak” or mahogany finish.
Cockpit and Deck Equipment
Beneteau claims the cockpit matches that of a 55-footer. Large lounging pads sit on either side of the companionway, and the drop-leaf cockpit table contains a refrigerator forward and life-raft stowage aft. A substantial swim platform completes the stern.
A composite sprit carries a Code 0 and keeps the anchor clear of the plumb bow. The aft lazarette has room for fenders, lines, and a Fischer Panda genset, with all-around access. Hideaway dinghy davits borrowed from the Jeanneau line retract flush when they aren’t in use. An optional grill swings out from the aft bench, allowing the cook to stand on the swim platform.
The companionway is arranged as a staircase rather than a ladder and has solid handrails. Optional systems include Dock & Go joystick control, which integrates the engine, thruster, and autopilot, as well as Seanapps remote monitoring.
Known Issues
Testers criticized several practical details. On the port side, the fresh-water and waste deck fills are only about 4 inches apart, creating a real contamination risk during fill-ups.
At the starboard wheel, the engine throttle, wind-instrument repeater, windlass remote, and bow-thruster control are grouped around ankle level. They’re awkward to reach and easy to bump. The helm consoles are also small compared with the massive cockpit table and can accommodate only a 9-inch MFD.
The Verdict
The Oceanis 51.1 is a thoughtfully modern cruiser that trades some traditional refinement for volume, easy handling, and a genuinely fast hull derived from racer logic. Its chined, infused construction and highly configurable layouts make it a strong platform for a couple or family. However, the close-set deck fills and ankle-level controls deserve a buyer’s attention.
Pros
- Full-length chine hull derived from an ocean-racing form, intended to reduce wetted surface and add buoyancy
- More than 700 possible combinations of layouts, rigs, keels, and options
- Standard self-tacking jib and one-winch-per-helm line handling simplify shorthanded sailing
- Bright, roomy interior with as many as five cabins and saloon seating for up to 14
Cons
- Port-side water and waste fills only about 4 inches apart
- Engine and thruster controls at ankle height beside the starboard wheel
- Helm consoles too small for a display larger than 9 inches
