Lagoon SEVENTY 8

Announced a few months ago, Lagoon unveils its new gem: the SEVENTY 8 Motor Yacht.

This true masterpiece of innovation will take you into a world where elegance, details and choice of materials are the watchwords. With her precious materials and her long range, the SEVENTY 8 blends the requirements of offshore cruising with the standards of a prestigious Motor Yacht.

As with her award-winning sister, the Lagoon 630 Motor Yacht, refinement and comfort combine with impressive performance and trans-Atlantic range.

The first showing of the SEVENTY 8, the largest of the Lagoon Motor Yacht range, was at the Cannes Boat Show in September 2017, with its US debut at the Fort Lauderdale Boat Show in November.

Hull #1 made the trans-Atlantic crossing on her own bottom, on standard fuel tanks, between these shows.
