Our commitment to sustainability at Lagoon is to minimize our impact on the planet’s environment. We are prioritizing our sustainable solutions and environmental care in our company’s strategy.

To meet the demands of a new generation of owners, Lagoon teams are adapting and reinventing themselves. The new Lagoon 51 offers options of XXL solar panels of the roof. This technology provides the guests aboard with more than 3.400 watts to operate the yacht.

Being powered by these solar panels, the catamaran is fully autonomous while staying visually appealing. The panels fit perfectly into the lines of the catamaran’s design and do not interfere with life aboard. Even making access to the flybridge and sunbathing pads still accessible. Life aboard does not change with this upgrade to our 51’s design.



The Lagoon 51 has a flybridge that was optimized to cover 80% of its roof. Equipped with modular seating so you can accommodate as many guests as you would like, this allows you to welcome them to the helm and relax alongside the captain. I unique experience for your guests to enjoy.

With 2 large sunbathing pads in front of the helm station and a spacious C shaped seating area with a table that can be lowered creating an XL sunbathing area, this gives you substantial space to accommodate all of your guests with ease.

Two staircases lead to the fly aboard the 51 catamaran, one for the helmsman and one for the guests. This double access allows for a great flow between living spaces on the board, a common theme throughout the entirety of the yacht.

Full headroom in the flybridge allows for this space to be safely appreciated at both anchor and underway. Maneuvers are at hand from steering station, while the guests can walk around without disturbing the helmsman.

Discover a truly convivial and sociable space.


As you walk along the side decks, you’ll reach the forward cockpit. This stunning space has an unobstructed view of the ocean and open horizons. Whether sharing the sun or laying back in the shade the cockpit has many amenities to make sure you are at your maximum comfort level on the Lagoon 51.

The space has a comfortable seating area with a coffee table in the center and sun protection so you’re sure you can enjoy every moment possible with unimaginable views.


The extended transoms on our new Lagoon 51 model makes for effortless boarding. This feature brings safe and practical access to the dock side. Between the transoms is our tenderlight.

The tenderlift acts as a large balcony by the sea. At mooring, the platform transforms into a bathing platform, an invitation for swimming and relaxing with your feet in the water.

Finding your way from transom to cockpit is easier than ever with improved access of a two-step staircase. With this practical solution applied to our design, it is a major accomplishment on the catamaran market to meet an important need of our customers.


“The raised lounge of the saloon offers the best 360° panoramic views of the water.” – Nauta Design

Step into a spacious saloon and discover the newfound space of the 51. Thanks to the mast being moved to the fore end of the saloon, the view from the room is continuously panoramic. The new wood finished with Alpi sand oak reinforces the brightness in the space alongside the natural light pouring in from the windows. This brightness in the saloon makes the 51 feel like home.

From every angle and perspective, this catamaran’s saloon’s space is impressive allowing for easy movement through the interior. To make it even better, the saloon is fully furnished with all the practical amenities one needs aboard their yacht.

As expected, the owner’s suite offers you ideal comfort. The optimization of the 51’s layout design has benefited this space as well by adding a large walk in dressing room as part of the standard.
