The Nautitech Open 40 is part of a growing trend among cruising catamaran designs to soften the distinction between inside and outdoor living spaces. As a result, this new model offers supremely spacious living accommodation for its size, without unduly compromising sailing qualities, thanks to the relatively narrow hulls drawn by renowned designer Marc Lombard and careful attention to minimising unnecessary weight. Take a look for yourself in the Nautitech Open 40 First Look Video.

Below decks

The most striking feature of the accommodation is the main bridgedeck living area that blurs the distinction between inside and outside zones. The forward section, which can be fully enclosed by a pair of patio doors, houses a well-appointed galley, plus a small dining/lounging area that can also double as a navigation station. This area benefits from huge windows that give plenty of natural light, as well as an almost all-round view.

The main lounging and dining spaces are outside under the protection of the hard top. This arrangement gives an impressive amount of room compared to more conventional layouts on multihulls of this size. The benefits for boats that are used predominately in warmer climes, or during a north European summer, are very clear. In particular, owners and guests are able to spend more of their time outside, where they may be cooled by the breeze, but with the benefit of being shaded from the sun. This area is set up so that bug screens, or canvas to keep wind and rain at bay, can be easily rigged. It can also be heated to help maintain comfort levels during spells of inclement weather.

The interior blends in seamlessly with the sheltered covered cockpit area outside.


The starboard hull houses two double cabins, plus a spacious heads compartment. Two options are available for the port hull – either a further two cabins, mirroring the arrangement in the starboard hull, or a spacious owner’s suite that stretches for much of the length of the yacht. In addition, there’s provision for two single berths for occasional use right forward in each hull.

On deck and performance

Although it has the potential to be a quick vessel, this boat is designed to be easy to handle: “There’s an emphasis on ease of sailing, with fixed keels and a simple deck layout, keeping it light,” says designer Marc Lombard. Most sail handling controls are taken to the two helm positions at the aft end of each hull, where they are clear of anyone who wants to relax in peace under the hard top. Although the view from the helm stations is arguably not as good as that from a flybridge or mezzanine level helm, this arrangement has the benefit of keeping weight to a minimum and helps to maximise the living space under the hard top.

With a displacement of just under eight tonnes, this boat is lighter than many of its contemporaries, while the fine hull shapes and generous sail area, including a fashionable fat-headed mainsail, promise good performance and quick passage times. The simplicity factor extends to the fixed keels – rather than more complex, but efficient, daggerboards. Overall, this points to a boat that will be relatively easy and hassle-free to sail, despite its undoubted speed potential.


Equipment and options

Two key specification options are available, including an Exclusive Finish package that includes a higher standard of finish and detailing.


What it does best

Nautitech says this model was intended to deliver an innovative, fast and fun experience. The boat certainly succeeds in this context, while also benefitting from the unusually spacious feel of the bridgedeck accommodation that provides a lot more space than previous generations of catamarans of this size. Sleeping accommodation in the hulls can be arranged to suit the needs of owners or those of charter parties.



The biggest drawback for those in search of all-round space is that the narrow hulls limit room in the sleeping quarters. Although these are still of a very respectable size for a boat of this length, they don’t match the expansive bridgedeck accommodation. Those who are looking for a boat with multiple sun bed locations will also not find as many on this boat as on catamarans with a flybridge layout.

The narrow hulls aid sailing performance but somewhat cramp the sleeping accommodation.


Other models in the range

This model is the smallest in this French boatbuilder’s main range of cruising catamarans, which also includes designs at 48ft and 54ft, plus a 40ft powercat.


Alternative boats

For those whose who are happy to compromise performance for extra space and weight the Lagoon 39 offers wider hulls together, with the option of a four cabin, four heads layout. However it is some 45 per cent heavier than the Nautitech, which will inevitably have an impact on sailing performance.

A possibility for those who are happy to trade easy handling for extra performance is the Catana 42, which has daggerboards in place of the fixed keel and a more powerful sail plan. Alternatively, the Broadblue Rapier 400 offers a similar concept to the Nautitech Open 40 in terms of layout, but in a significantly lighter and faster package – it’s a boat that weighs only five tonnes.
