The Outremer 4X is a high-performance evolution of the popular Outremer 45, designed by Barreau/Neuman to bridge the gap between dedicated racing multihulls and comfortable blue water cruisers. Launched as a specialized "carbon edition," the 4X utilizes the same primary hull molds as the 45 but incorporates extensive carbon fiber reinforcement in the bulkheads, roof, and deck to shed weight while increasing structural rigidity. The most notable physical difference is the extension of the transoms, which brings the overall length to approximately 48 feet, enhancing the theoretical hull speed and providing cleaner exit lines for the water. Since its debut, the 4X has solidified its reputation as a "gentleman’s racer" for the cruising world, famously winning the European Yacht of the Year award in the Multihull category shortly after its release.

Sailing Performance & Handling

The sailing philosophy of the Outremer 4X centers on power-to-weight efficiency. By utilizing a carbon fiber rotating mast and high-modulus rigging, the boat carries a significantly larger sail plan than the standard 45. Technical reviews from Sail Magazine highlight that the 4X is capable of sailing at wind speed in light air, a feat rarely achieved by cruising catamarans laden with offshore gear.

Handling is defined by the use of deep, retractable daggerboards rather than fixed mini-keels. This allows the 4X to point higher upwind—often achieving tacking angles comparable to performance monohulls—and reduces drag when reaching or running. A signature feature of the Outremer experience is the optional twin carbon tillers located at the aft end of each hull. While a traditional bulkhead steering wheel is provided for inclement weather or motoring, the tillers offer the helmsperson a tactile, dinghy-like feel, allowing for precise control and a direct connection to the rudders that is typically lost in hydraulic or cable-steered multihulls. According to editorial testing by Yachting World, the 4X maintains a composed motion even when pushed into the mid-20-knot speed range, courtesy of its narrow, high-bridgedeck hulls that minimize "slamming" in chopped seas.

Interior Comfort & Variations

While the 4X is optimized for speed, the interior—designed by Franck Darnet—does not lean into the Spartan aesthetic common in racing boats. Instead, it utilizes lightweight cabinetry materials, such as Nida-core (honeycomb) panels with thin wood veneers, to maintain a high-end finish without the weight penalty of solid timber. The layout is typically offered in a three-cabin "Owner" configuration, where the entire port hull is dedicated to a master suite featuring a large longitudinal berth, a desk/vanity area, and a spacious head forward.

The starboard hull generally houses two guest cabins sharing a central head. A four-cabin version exists but is less common on the 4X, as the model’s target demographic usually prioritizes the weight savings and luxury of the owner’s layout. The salon offers 360-degree visibility, a hallmark of the Barreau/Neuman design, and integrates the galley with the cockpit through a large sliding door, creating a seamless indoor-outdoor living space. Headroom remains generous throughout the hulls and salon, though the narrowness of the hulls (essential for performance) means the cabins are more compact than those found on "floating apartment" style cruisers from high-volume manufacturers.

The Outremer 4X gained significant international attention when it was named the European Yacht of the Year 2017. This accolade propelled the model into the spotlight of the performance cruising community. While many high-profile YouTube voyagers, such as those on Sailing La Vagabonde, have operated the sibling Outremer 45, the 4X is frequently cited in technical sailing journals and performance-oriented media as the "gold standard" for a production performance cat. It also features prominently in the Outremer Cup, an annual regatta held in the south of France where owners gather to race and share technical knowledge.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the 4X with a "performance-first" mindset, as the vessel's integrity is closely tied to its weight and rig tension.

  • Weight Sensitivity: The most common "issue" is not a factory defect but owner-induced. Adding heavy aftermarket equipment like large diesel generators, oversized tenders, or washing machines can significantly degrade the 10-15% performance advantage the 4X has over the standard 45.
  • Daggerboard Trunks: Inspect the daggerboard trunks for wear on the sacrificial bearing strips. High-load sailing can cause these to wear down, leading to "clunking" sounds while underway.
  • Carbon-to-Glass Transitions: While the construction is robust, a surveyor should specifically check the secondary bonding areas where carbon fiber reinforcements meet the traditional fiberglass hull sections for any signs of stress cracking or delamination.
  • Rigging Inspection: Given the 4X is often sailed aggressively, the standing rigging—especially if it is the optional Kevlar or carbon variety—requires strict adherence to replacement intervals, as these materials do not show fatigue as visibly as stainless steel wire.

Community & Resources

Owners of the 4X benefit from the extensive "Outremer Family" network managed by the builder, Grand Large Yachting. This includes access to the Grand Large Services division, which provides technical support, refit assistance, and specialized training for long-distance cruisers. The most prominent community event is the Outremer Cup, a technical and social regatta that offers a wealth of anecdotal data on sail trim and hull maintenance.

The Verdict

The Outremer 4X is a specialized tool for the sailor who views the passage itself as the destination, offering a level of engagement and speed that few cruising multihulls can match.

Pros

  • Exceptional light-air performance and high top-end speeds.
  • High-quality lightweight construction using carbon fiber in key structural areas.
  • Tactile tiller steering provides a superior helming experience.
  • Strong resale value due to the brand's prestige and limited production.

Cons

  • Significantly higher price point compared to standard cruising catamarans.
  • Performance is easily compromised by excess weight and "cruising clutter."
  • Narrower hull sections provide less interior volume than beamier competitors.
  • The open helm and tiller positions offer less protection from the elements during heavy weather.
