Continue to navigate through the options of customization and be sure to elevate the comfort levels throughout your yacht. With the ease of connected spaces, you’ll find that there’s room for happiness everywhere aboard.

The SEVENTY 8’s massive flybridge can be customized with what you wish. Entertain yourself and your guests by installing a Jacuzzi or a large folding dining table to starboard. Or if you would rather, choose a magnificent sunbathing area to bask in the sunshine. There’s even a hard top / bimini which can be opened and closed electronically.

With an ergonomic helming station equipped with a seat to starboard, enjoyment of the experience of navigating the vessel while admiring the immensity of the ocean is a given.

An unrivalled space for relaxation and freedom is a forward platform prepared for dancing and entertaining. The aft cockpit is where you can find yourself relaxing and feasting. Linking two transom skirts is a tenderlift platform giving you an exceptional bathing deck.

ENTER a luxurious and harmonious world

The masterful Nauta Design teams were meticulous in depicting an interior that captures luxury in every design implemented onboard. Well-balanced finishes and a refined interior paneling furnish the SEVENTY 8 with a harmonious, distinctive elegance. Light is brought to every corner through the portholes and large hull tints making this vessel’s harmony even more palpable to its owner.

Unparalleled panoramic views in the contemporary salon are complimented by its exceptional headroom. In the center is a door giving a beautiful flow between interior and exterior living. With an easily accessible cockpit from the salon there is exceptional communication throughout the catamaran.  

The SEVENTY 8’s owner’s suite, privately located from the rest of the yacht, provides you with access to the sea with a private terrace, our favorite technological gem at Lagoon. The suite is lavishly furnished, making your home away from home a blissful experience to enjoy time and time again.



You dream it, we'll make it

Create the oasis you’ve always dreamed of. With 269 sq. ft. of fully configurable space, the SEVENTY 8 enables you to create your very own catamaran customized to your needs.
