The GX42 Coupe is the sportier face of GX Superyachts’ debut platform, sharing the 42 metre aluminium hull and hybrid heart of the raised pilothouse GX42 but wrapping it in a lower, sleeker superstructure. Built at SES Yachts in Istanbul, she pairs twin MAN D2862 diesels with two 200 kilowatt electric motors, a large lithium battery bank and up to 39 kilowatts of solar on the hardtop. The payoff is the same quiet promise the yard was founded on: around 100 nautical miles under electric power alone, close to 48 hours of silent operation at anchor with air conditioning running, and a claimed sharp reduction in carbon against a comparable diesel yacht.
Marco Casali of Too Design drew both the coupe profile and the interior, favouring walnut, white leather and Italian fabrics over showy excess. Accommodation mirrors the pilothouse version: ten guests across five cabins, with the owner given a private area and a dedicated head. Francesco Rogantin of NAMES studio shaped a hull that holds 12 knots as a comfortable cruise and reaches 16 at the top end, with range measured in five figures.
She sits within a planned 24 to 56 metre range offered in RPH and Coupe forms, and makes a serious case for the buyer who wants genuine quiet, real efficiency and semi custom freedom in a sportier shape.

Two MAN D2862 diesels and two 200 kilowatt electric motors drive the GX42 Coupe, fed by a large lithium battery bank and up to 39 kilowatts of solar on the hardtop. In electric mode she makes around six knots and covers close to 100 nautical miles in silence; under diesel she cruises comfortably at 12 knots and tops out near 16. Range runs into five figures. The real headline is life at anchor, where the batteries and solar carry the hotel load, air conditioning included, for up to 48 hours with no noise, vibration or emissions. At 245 tonnes she is tuned for efficiency rather than outright pace.
Casali gave the Coupe a lower, more athletic profile than the raised pilothouse GX42, with a long curved hardtop that hides the solar array in plain sight. The lines are clean and horizontal, a dark glazed band running the length of the superstructure to keep the volume looking light. Aluminium construction keeps weight down and allows generous glazing. Deck space is arranged for family use rather than show, with room for tenders and water toys and easy movement between the bathing platform, the main deck and the upper lounge. The result looks quick standing still without resorting to aggression.
Below, the GX42 Coupe sleeps ten guests in five cabins, with the owner given a private area and a dedicated head. Casali’s palette leans on walnut, white leather, lacquered surfaces and Italian fabrics, a combination that feels warm rather than clinical. Natural light was clearly a priority: hull windows and superstructure glazing pull the sea inside, and the owner’s bathroom pairs marble with a framed sea view. The brief was family minded, so the layout favours comfort and flow over formal grandeur. Crew accommodation handles up to seven, enough to run her properly on longer passages while keeping guest and service areas separate.
The GX42 Coupe is built around the idea that the best part of a yacht is time spent still. Because she can hold her systems silently at anchor for two days, the social spaces are designed to be lived in rather than motored between. The main deck salon opens to the sea, the hardtop shelters an upper lounge, and the bathing platform brings guests close to the water. The absence of generator noise changes the feel of every evening on board, and the hybrid system means an owner can anchor in a quiet bay without running a diesel just to keep the lights and air conditioning on.
She is built in aluminium at SES Yachts in Istanbul, a yard with real metal expertise, to a semi custom brief that lets owners shape the interior and systems. The 42 metre Coupe carries around 335 gross tonnes of volume, a little less than the raised pilothouse version in exchange for its sleeker profile. No list price has been published for the Coupe; as a guide she sits close to the 32 million euro reported for the first GX42. Buyers get the backing of the Greenline team’s hybrid experience, a classification build and the running economy that comes from spending less time on the generators.
