Greenline Yachts launches hybrid propulsion brand GX Superyachts at Monaco Yacht Show

Hybrid boatbuilder Greenline Yachts has launched a new brand, GX Superyachts, at this year's Monaco Yacht Show.

The range will encompass aluminium builds from 24 to 56 metres, with the first 42-metre model already sold and under construction at SES Yachts' facilities in Tuzla, Turkey. Delivery is scheduled for summer 2026.

The brand hopes to "set a new benchmark in environmental performance" with its serial hybrid drive, battery bank and integrated solar arrays, previously used within the Greenline brand. 

Each model will be able to reach six knots and a range of up to 100 nautical miles in electric mode, with the shipyard promising "less than 40 per cent of the carbon emissions" of a conventional yacht. The range's efficient hull design is owed to Francesco Rogantin of NAMES studio.

Marco Casali of Italian studio Too Design is responsible for the exterior, with two variants available: the Coupé and the RPH. The Coupé has a long, curved superstructure roofed with solar panels that slide apart to reveal a hidden sun deck, complete with Jacuzzi and bar. Meanwhile, the RPH version offers a flybridge with a volume of 353GT. Both designs benefit from a beach club with fold-down wings and a hydraulic platform.

Interior design is also owed to Casali, who has opted to use "specialized brands" such as Antonio Lupi, Dornbracht and Poltrona Frau. "I am proud of the way we have reinterpreted the timeless looks of the smaller [Greenline] yachts to give soul and purpose to the lines of the new superyachts," said Casali, "The challenge around sustainability is particularly close to my heart."

The GX range will be capable of "silent" anchorage for 48 hours or more. The battery bank will power the hotel load during this time, including air conditioning, for "no noise, vibration or smell" from combustion. 

In diesel mode, the yachts will have a maximum speed of 12 knots and an impressive range of 11,571 nautical miles at six knots.
