The hybrid option includes two 23kW electric motors, up to 4.5kW of solar energy from 10 photovoltaic panels and up to six 11kWh lithium batteries

Vladimir Zinchenko, founder, owner and CEO of Slovenian boatbuilder Greenline Yachts, puts it simply. “Fantastic design has no shelf life. We don’t seek to constantly update or replace our models. Therefore, when we do finally introduce a new boat, it’s no light decision.”

Zinchenko is talking about the new Greenline 42, introduced to the world at Boot Düsseldorf in Germany in January 2026. The new 44ft model arrived on the scene three years after Greenline last expanded its lineup of hybrid motoryachts with the addition of the flagship 58 Fly in 2023. According to Greenline Yachts, the Greenline 42 has taken “several years” to complete, from initial concept to launch.

It originally began as a project to revamp the Greenline 40, one of the longest-standing models in the range and which has sold hundreds of units since its launch in 2012. However, the new model eventually took on a life of its own, becoming the new Greenline 42.

Zinchenko says: “With the feedback we gathered from our existing owners and commercial prospects, we began to see that the Greenline 40 still had a hugely loyal following. There remain many good reasons for people to buy that boat. So, I decided to add a new model rather than replace an established one.”

Carrying the tagline of an “icon, redefined”, the Greenline 42 was developed from a brief informed primarily by owner feedback.

Alessandro Lorenzon, Greenline Yachts’ Global Business Director and Chief Experience Officer, explains: “When we looked at owners’ experiences, a few things became clear. They wanted more cockpit space for relaxing, higher speeds under power and a more modern design language. The new Greenline 42 supplies all that and more.”

The Category B yacht has emerged as a happy marriage between the 40 and 45 models, a new 13.5m-long vessel that takes the best features from both and neatly fills the gap between its smaller and bigger sisters.

GREENER THAN EVER

Since Greenline Yachts launched its first hybrid vessel in 2008, the brand has been committed to helping its owners enjoy yachting in a sustainable way. Greenline claims to be the only brand worldwide to offer conventional, hybrid or electric drive options across its entire fleet. Its full range of vessels – even the flybridge models – sport a characteristic, streamlined roof specifically designed to accommodate solar panels.

The Greenline 42 carries the most solar panels in the fleet, fitting 10 450W photovoltaic panels flush mounted on the coachroof. In total, the solar coverage delivers up to 4.5kW of energy, enough to run all onboard appliances.

Surplus energy is diverted into the battery bank, with two 11kWh batteries offered as standard with the hybrid option. The total output of 22kWh can be upgraded to as much as 66kWh with four additional batteries. With this technology, the Greenline 42 can run on silent electric power for 48 hours or more, even with the air-conditioning running.

Lorenzon says: “Thanks to technological improvements, we were able to integrate more solar panels into a yacht of this size than ever before, matching the total solar output of the 58 Fly, despite being significantly smaller.” He adds that with this new design, “the Greenline 42 maximises onboard renewable energy without compromising space”.

The hull design of the Greenline 42, rethought by MICAD, has also been refined to reduce drag underway while also increasing stability. This optimisation, combined with two 250hp Yanmar diesel engines, allows the 42 to hit top speeds of 25 knots, which is three knots faster than the 40.

The new model also features Greenline’s proprietary H-Drive technology, with two powerful 23kW electric motors able to power the boat silently up to 20nm at a speed of five knots.

ITALIAN DESIGN

An upgraded design was just as important as improving the performance on the Greenline 42. Marco Casali of the Too Design studio, a recurring partner on Greenline projects, returned once again to add Italian flair to the project, having previously collaborated on the interiors of the Greenline 45 and overseen the full design of the Greenline 58 (available in Fly and Coupe versions).

“Marco Casali was a natural choice for the Greenline 42 project,” Lorenzon notes. “He was already deeply familiar with our design philosophy, making him the perfect fit to shape the new model.”

Many yachts boast of a ‘seamless’ connection with the sea, but rarely is this so well encapsulated as on the Greenline 42. While the modification options are abundant, the principal layout of the main deck runs smoothly across a single level from the helm station, complete with its own climate control dashboard, through to the saloon midships then galley and cockpit aft.

With the option to fully open the access between the galley and cockpit, as well as automatic sliding windows for further ventilation, the entertaining space can be completely opened to the sea breeze to enjoy a truly indoor-outdoor experience. An additional lounge at the bow further expands alfresco entertaining options.

Inside, generous headroom, ample storage and panoramic windows ensure a light, airy and uncluttered interior. The interior design also keeps the focus on the great outdoors with subtle styling built around a natural colour palette and renewable materials, with owners able to choose a ‘honey teak’ or ‘modern oak’ finish.

Greenline specifies that Casali concentrated on “creating refined shapes and living spaces rather than using expensive, exotic materials” in his styling of the Greenline 42.

“With the new Greenline 42, there was a tightrope to walk,” Casali says. “We wanted to rework the Greenline 40 without giving the sense that everything was ‘new’. There was a big focus on the forms you see around the boat, so we have avoided curved cabinetry in favour of more linear edges. This echoes the masculine profiles seen in the cutaway bulwarks and the coachroof.”

OPTIONS IN AND OUT

Looking beyond performance, the Greenline 42 is also a frontrunner within the range as the brand’s “most customisable model ever”. Although the exterior is still distinctly Greenline, there are more options than on other models.

For the cockpit, owners can opt for a four-seater table and a hydraulic aft platform, or a fold-down swim platform and a clear aft deck offering open space for sunbathing and lounging.

Casali has a favourite: “I’m in love with the possibilities offered by the connection between the cockpit and the galley-saloon area. My favourite one is with a big table related to the open galley.”

Other options for the main deck include adding an extra fridge or freezer in the galley, a second sofa in the saloon, or an additional drinks table in the bow lounge. Either way, a fully integrated pop-up TV to starboard can be hidden or deployed in an instant.

Guest cabin to port

Below deck, there’s a master cabin forward and a twin cabin to port. Owners can choose between offering a second bathroom with en-suite access from the guest cabin or expanding the en-suite master cabin with a walk-in wardrobe or vanity table.

MADE TO LAST

The new design of Greenline’s latest model is already proving popular, with the shipyard confirming half-a-dozen sales to owners across Europe as well as “great interest from the Asian market”. Going forward, Greenline hopes to deliver about two units per month of the new model.

The early demand for the Greenline 42 rewards its customisable nature and what Lorenzon describes as the “longevity of our designs”.

As Zinchenko puts it, the Greenline 42 is not simply a new-fangled model. It’s an amalgamation of research and feedback packed into a form designed to last for the long-term.

“Timeless, long-lived design is a key part of our ‘Responsible Yachting’ commitment,” Zinchenko says. “You can be sure that the new Greenline 42 has absorbed every inch of our know-how and will provide a reference in the market for decades to come.”
