The Nautitech 40, originally designed by the naval architecture firm Mortain & Mavrikios, represents a foundational chapter in the history of the French shipyard. Launched in the early 2000s, this 12-meter catamaran established the brand's core identity: a focus on "sailor-first" ergonomics and slender hull forms that prioritize speed and sea-kindliness over the sheer internal volume favored by many of its contemporaries. Unlike the later "Open" series designed by Marc Lombard, the original Nautitech 40 and its successor, the 40.2, feature a more traditional coachroof profile while maintaining the brand's signature twin outboard helm stations. This model was instrumental in positioning Nautitech as a manufacturer that caters to cruisers who value the "feel" of a boat under sail, bridging the gap between performance multihulls and heavy-displacement cruising cats.

Sailing Performance & Handling

The Nautitech 40 is frequently praised for its balance and responsiveness, a direct result of its relatively narrow hulls and a bridge deck clearance designed to minimize "slamming" in choppy conditions. With a displacement of approximately 7,400 kg and a generous sail area, the boat maintains a favorable power-to-weight ratio. According to editorial testing by Multihulls World, the vessel’s slim waterline entries allow it to point higher than many other production catamarans of its era, often achieving up to 35-40 degrees of apparent wind angle with minimal leeway.

The defining characteristic of the handling experience is the twin aft helm stations. By placing the helmsman at the rear of each hull rather than on a raised bulkhead or flybridge, Nautitech lowers the center of gravity and provides the sailor with a clear view of the sails and the water's surface. While this configuration leaves the helmsman more exposed to the elements compared to a protected cockpit, it offers a mechanical steering directness that is often lost in more complex cable runs. Owners frequently report that the boat tracks exceptionally well, requiring minimal autopilot intervention in steady trade winds.

Interior Comfort & Variations

The interior of the Nautitech 40 was designed to be functional and bright, utilizing large wraparound windows to provide 360-degree visibility from the saloon. The woodwork is typically a light Alpi or cherry veneer, which helps maintain an airy feel despite the hulls being narrower than those of a Lagoon or Fontaine Pajot.

The model was primarily produced in two configurations:

  • The Owner’s Version: Features a dedicated master suite in the starboard hull, complete with a large double berth aft, a desk or vanity midships, and an expansive head/shower compartment forward.
  • The Charter/Club Version: Utilizes a symmetrical four-cabin, two-head layout, which was popular in Mediterranean and Caribbean charter fleets.

In 2005, the shipyard introduced the Nautitech 40.2, a refined sibling built on the same hull. The 40.2 featured a redesigned coachroof that provided better protection for the cockpit and updated the interior ergonomics. The 40.2 is often sought after on the pre-owned market for its improved galley layout and slightly more modern aesthetic finishes compared to the original 2003-2004 builds.

Known Issues & Buyer’s Checklist

Prospective buyers of the Nautitech 40/40.2 should focus their inspections on several high-signal areas common to multihulls of this vintage:

  1. Steering Linkages: Because the twin helms use a cross-over system to synchronize the rudders, the bushings and cables are subject to wear. Any "play" in the wheel often indicates that the steering cables need tensioning or the rod-end bearings require replacement.
  2. Bridge Deck Integrity: While the 40 is robustly built, older models should be checked for stress cracking at the forward corners of the coachroof and the forestay attachment points, especially if the boat has been driven hard in charter service.
  3. Saildrive Seals: Most units are powered by Volvo Penta or Yanmar engines with saildrives. Ensure the rubber diaphragm seals have been replaced within the manufacturer's recommended 7-year window.
  4. Bimini and Canvas: The original bimini design was somewhat minimalist. Many owners have since added "hard-top" conversions or extensive solar arrays. Buyers should inspect the mounting points for these aftermarket additions to ensure they haven't compromised the deck core.

Community & Resources

Owners of the original Nautitech 40 often find technical support and community through the Nautitech Owners Association, a group dedicated to the maintenance and cruising of both the older Mortain/Mavrikios designs and the newer Lombard "Open" models. While the shipyard is now under the Bavaria Yachts umbrella, technical documentation and legacy brochures can sometimes be requested through Nautitech Catamarans' official contact channels.

The Verdict

The Nautitech 40 remains a standout choice for the "sailing purist" who wants the stability of a catamaran without sacrificing the tactile joy of helming. While it may lack the massive interior volume of modern "floating apartments," its sea-kindly hull and efficient design make it a superior choice for long-distance blue-water cruising.

Pros

  • Superior Sailing Dynamics: Excellent windward performance and steering feedback for a cruising catamaran.
  • Safety and Visibility: Low-profile design and twin helms provide great visibility and a low center of gravity.
  • Build Quality: Historically strong vacuum-infused construction that has aged well over two decades.

Cons

  • Exposed Helm Stations: The helmsman is vulnerable to rain and spray without custom canvas enclosures.
  • Narrow Hulls: Storage space and cabin width are slightly less than contemporary competitors.
  • Accessibility: Moving between the twin helms requires crossing the cockpit, which can be cumbersome in heavy weather.
