The Lagoon Seventy 8 Motor Yacht is without doubt the flagship of the powercat range.
With build slots available offering extensive customisation, the details you see here are an example specification for a fully equipped owners version of the Seventy 8.
The owners layout on the Lagoon Seventy 8 is truly exceptional.
A large VIP cabin aft allows for the remaining starboard hull to be dedicated to the owners and is complete with a walk-around, athwartships king-size berth facing hull windows, a walk-in closet forward with built-in bureaus, a love seat under bookcases, a desk/vanity and a marble-lined en suite head with shower.
There is also the unique option available whereby a bulkhead folds outboard to become a private teak beach where owners can soak up the sun rays or simply enjoy a coffee and croissant in the morning.
The Seventy 8’s one-level saloon exudes cool elegance and owners are given a blank sheet of paper to arrange the space as they wish.
Like the rest of the Seventy 8, the flybridge is stunning in its space and the layout is ready to customize. Owners can choose a hot tub with surrounding sun pads or a rail-to-rail sun pad aft. A bar with stools or a dining table that seats eight can be added without crowding.
Whatever the choice, the skipper has a centerline helm forward and a double seat companion chair to starboard.
We would be very happy to discuss all options available for a forward order Lagoon Seventy 8 motor yacht so please don't hesitate to contact us for further information. Competitive part-exchange and finance options available.
