You take the same ones and start again... The adage is rather true for the Lagoon Seventy 8 since it was designed in the same moulds as the Seventy 7 with the difference that the reinforcements are different. "When the Seventy-eight was designed, the aim of the Seventy-eight was to be able to cover 4,500 nautical miles on a single tank of fuel." explains Olivier, in charge of yacht unit deliveries at Lagoon/CNB. A successful gamble, since with its impressive 8500 l tank, the motor catamaran can cross the Atlantic in one go at a speed of 8 knots, even if its cruising speed is more like 20 knots.
To accentuate the "luxurious" side of its biggest catamaran, the Bordeaux yard has opted for space, comfort and numerous living areas. "To give you a comparison, the dimensions of the Seventy-eight are those of a tennis court!" comments Olivier. You can access the boat via the very large aft platform (extended from the Seventy 7 ) which can accommodate a tender and connects the two very large skirts. After a few steps, we find ourselves in the large aft cockpit with a lazy space on the port side, a large aft seat and a dining area. You also access the fully equipped galley, installed in the aft port hull.


The saloon - on the same level as the cockpit - is partitioned to offer many distinct living spaces. But always with the objective of "offering a kitchenette: sink, fridge and cooler in each living area. Thus, there is a dining area on the port aft, the helm station on the port bow, an "intimate" saloon forward and in the centre (one door of which allows you to disembark on the foredeck), and a saloon on the starboard side. The entire saloon is glazed to provide maximum ventilation light and a 360° view of the sea.


The private areas are accessed from the living room, with independent descents. The configurations are numerous and the Seventy 8 can accommodate up to 5 cabins with double bed, stowage lockers and private bathroom. In the owner's configuration, as we visited it in Cannes, the starboard hull houses on the bow the very large owner's cabin with its private bathroom, with separate shower and w.c., as well as a large walk-in wardrobe and a private bathing platform that opens into the bulwark. An element that we had already appreciated on the sailing version.



The aft of the starboard hull accommodates a double cabin, while the port hull accommodates a guest cabin on the forepeak, then a crew cabin (a minimum of two crew members is required to sail comfortably aboard the Seventy 8) and finally the galley. Each cabin has its own bathroom.


To support her luxury positioning, the Seventy 8 offers 25m2 of "custom" space in the galley version at the bow, leaving the owner the choice of layout of the aft port hull: games room, meeting room, massage room, cinema... Below deck as well, light floods in thanks to the large hull windows.
On the main deck, the foredeck space is huge, with a 30 m2 platform, where the trampoline of the sailing version has been replaced by a structural part. It is easy to move around the catamaran, with very wide catwalks.

Access to the flybridge is from the cockpit where the space can be fully customised: jaccuzi, large folding dining table on starboard, sunbathing area at the bow, all protected by a hard-top/bimini with electric sunroof. The helm station with starboard seating allows steering from outside.


The Seventy 8's standard engine is a Volvo D11-510 hp and an optional John Deere N13-580 hp. With its extra-large fuel tank, powerful engine, large fresh water capacity and numerous comfort features, the Seventy 8 is clearly aiming to conquer the luxury cruising market with maximum convenience. However, some of the finishing details do not necessarily correspond to boats of this standard. It is a matter of series production, where boats of equivalent size are often custom-made. For information, Lagoon produces a new hull every 8 weeks.

In order to afford the Seventy 8, as a full option proprietary version (which is often the case on a unit of this size), it will be necessary to spend 4.3 million euros. A price which does not slow down the owners since currently already 16 units of the Seventy 7 are on order and 4 units of the Seventy 8. And the good news for Lagoon is a full order book until 2021!
