Lagoon developing Eighty 3 motoryacht
SHARE
Built on the same platform as the upcoming Eighty 2 sailing cat, the Eighty 3 will become the French builder’s flagship motoryacht.
Lagoon is scheduled to stage the world premiere of its Eighty 3 power catamaran at the 2026 Miami International Boat Show, which will be held in Florida from February 12-16. The Eighty 3 shares the same 23.91m (78ft 5in) hull as Lagoon’s upcoming Eighty 2 sailing catamaran, which will have its world premiere at this year’s Cannes Yachting Festival from September 9-14.
Like the Eighty 2, the Eighty 3 is a CE-certified yacht (A:14, B:18, C:24, D:40) and features naval architecture by VPLP Design, exterior design by Patrick le Quément and interiors by Italy’s Nauta Design.
However, the Eighty 3 offers more living space than its sailing sister, with a solid foredeck and a bigger flybridge – that can be covered in solar panels – contributing to 430sqm (4,628sqft) of living space. Fitted with two 580hp John Deere engines, the powercat has a transatlantic range of 3,500 nautical miles with a 8,500-litre fuel capacity.
The yacht’s design includes an open aft cockpit and a huge swim platform, of up to 22sqm, which can be configured to accommodate a jetski or a tender or simply as a waterside lounge area.
The portside staircase offers a safe, gentle incline to the flybridge, which offers 50sqm of space that can be personalised and configured by an owner and include a Raymarine-equipped helm station with joystick, dining table, outdoor galley and social areas.
The flybridge also offers large areas for solar panels including on the hard top and the aft overhang, with a Lithium battery pack also part of the yacht’s energy-saving technology.
The solid foredeck – accessed by two wide side decks and also from the saloon – has a sunken lounging area while the forward area can be dressed with loose furniture.
A huge modular saloon connects the aft cockpit and foredeck, and can be configured with a long dining table to port and a large lounge area to starboard, with the whole area illuminated by large windows. The forward area can include a bar area and lower helm station.
Interior furnishings feature fine materials including a marble table, armchairs with braided leather backrests, decorative glass panels, natural stone countertops, and woodwork in a brushed finish.
In the hulls, the Eighty 3 can provide four, five or six guest cabins, as well as crew accommodation. Like on the Seventy 7 and Seventy 8 models, the owner’s suite includes a king-sized bed with sea views and a large drop-down balcony that offers a private sanctuary over the water.
The Eighty 3 is in production at the Construction Navale Bordeaux, which builds all of Lagoon’s 50ft-plus catamarans. Bio-sourced resin and hemp fibre are being used in the hull, as well as on-structural parts, which dramatically lowers the CO² emissions in production.
