The new flagship of the Lagoon sailing catamaran range is the Lagoon SEVENTY 7.

Designed by the naval architects Van Peteghem and Lauriot Prévost (VPLP), and with a luxurious and innovative interior from Nauta Design, the SEVENTY 7 is a genuine superyacht and yet is unmistakably a member of the Lagoon family.

She is both a yacht for entertaining guests, with a broad choice of layouts and custom interior possibilities, and a catamaran offering high performance under sail... or under power in the case of the Lagoon SEVENTY 8 motoryacht version to be launched at the Cannes Yachting Festival in 2017.

The interior and exterior layout has been designed so as to give the feeling of being both inside and outside, unconstrained, from the cockpit to the saloon. The SEVENTY 7 offers direct access to the forward cockpit from the salon, a first for Lagoon.

The most innovative feature of the SEVENTY 7, however, is the "Private Beach"... for the first time on a sailing yacht, a hydraulically-operated hull door in the owner's suite opens to become a virtual private beach with direct access to the sea.

The owner's suite also features a king-sized bed, lounge area, bookcase, walk-in closet and a bright and spacious bathroom.

Multiple configurations of cabins, galley location and crew quarters offer unrivaled versatility for any sailing program (see layouts below).
