Greenline Yachts is a newcomer to the superyacht sector, but not to yachting. In its 15 years in business, it has delivered upwards of 1,000 yachts to 58 feet (17.7 meters). Equally important, they’re all hybrid or full electric yachts, with solar panels. The boatbuilder is bringing this experience to a series of large luxury yachts through a new brand, GX Superyachts.
GX Superyachts will build similarly hybrid-powered and solar-panel-equipped yachts from 78 to 164 feet (24 to 56 meters). The idea has its roots in an unexpected situation that occurred at the Monaco Yacht Show in 2018. There, Prince Albert II of Monaco expressed his liking for an all-electric 33-foot (9.99-meter) Greenline, which the builder was promoting as a superyacht tender. Later that same day, the prince requested Greenline to pick him up from one of the superyachts in the show and take him to the Monaco Yacht Club aboard it.
Regardless of size, all GX Superyachts will be hybrid. They also should see a range up to 100 nautical miles at 6 knots in electric mode. In traditional diesel mode, meanwhile, transatlantic crossings will be possible, at 12 knots. Notably, the longest range should be 11,571 nautical miles at 6 knots. Furthermore, the builder claims that each model will emit 60 percent less carbon emissions than fully diesel yachts. This is partly due to the propulsion system, but also the solar panels and batteries. Air conditioning and all other hotel loads will be able to run off the batteries alone for 48 hours or more at anchor.
GX Superyachts has tapped Marco Casali for styling the full range. Each model additionally is available as either a Coupé (above) or RPH (raised pilothouse, below) configuration. The Coupé has a curved superstructure with solar panels on top. Notably, those panels slide apart to reveal a sundeck with a hot tub and bar. The RPH, meanwhile, is more voluminous and has a big flying bridge. Both provide owners and guests with a beach club featuring fold-down sides and a hydraulic swim platform.
Already, one project is under construction. Specifically, the yacht is a 138-footer (42-meter), called the GX42 model, for a previous Greenline client. Marco Casali is handling interior design, too, striving for a seamless look between exteriors and interiors. The owner and guests will have furnishings and accessories from some of the top names in the superyacht sector. For instance, all furniture is from Poltrona Frau and Rugiano. Foglizzo leathers figure prominently, too.
The keel laying for the all-aluminum yacht took place on June 1. Already, more than 50 percent of the hull is complete. Delivery is set for the summer of 2026. Construction is taking place at SES Yachts in Turkey, since Greenline Yachts’ facilities in Slovenia can’t accommodate yachts larger than 78 feet (24 meters). Greenline’s team evaluated about 20 shipyards before choosing SES Yachts. Among the reasons, the shipyard is 50 years old, plus family-owned. Yet another important factor: The father, son, and daughter running the yard are all naval architects.
More details about the GX42 should be available in the coming months. In the meantime, in related news, Andrea Armas is serving as an advisor to GX Superyachts’ board of directors. Armas has 28 years of experience as an owner’s representative. “I admire their ambition and vision,” he says. “My goal is to help the team translate their decade-long experience in hybrid recreational boat building into the highly regulated superyacht sector.” (EDITOR’S NOTE, February 13, 2025: Northrop & Johnson is marketing the yachts in the Americas.)
