Greenline: From Power Management to Design Philosophy With Alessandro Lorenzon

Greenline Yachts has long been synonymous with innovation in hybrid propulsion, but its vision goes far beyond engines and batteries. Alessandro Lorenzon, global business director and chief experience officer, speaks on how Greenline balances incorporating cutting-edge technology while maintaining timeless yachting values. From diesel and diesel-electric hybrids to fully electric models, Lorenzon explains how Greenline’s approach to energy management, design and “Responsible Yachting” creates a new kind of boating experience that is deeply attuned to the pleasure of being on the water.

Greenline Yachts is renowned for its hybrid propulsion, but it also builds diesel-powered boats, right?

Yes. In fact, our sales are about half diesel-only models and half diesel-electric hybrids. One or two boats each year are also pure electric-powered. It is a busy marketplace for diesel yachts in the 39-58ft category, but Greenline boats stand out. Our technology makes a diesel boat more comfortable, easier to use and less fuel hungry.

How is a diesel yacht from Greenline Yachts different to its competitors?

What makes a conventional Diesel Powertrain from Greenline different to any other diesel boat is first and foremost the way we manage the energy on board. Thanks to our solar roofing, you already have a free source of energy that is always there, always available, and that’s standard on all our boats.

Secondly, we offer the option of additional battery banks, where you can store energy coming from the rooftop or recovered from the diesel engine. You then get the benefit of this energy later at anchor, silently running the boat’s hotel facilities – from air-conditioning to induction cooking. This means that you use the generator far less, reducing diesel consumption and lowering maintenance costs. But more than that, you will have better comfort, because there’s no noise, no smell and no vibration.

And is this technology mature?

Yes and no. Our power management system is in a class of its own, and already offers up to 48 hours of silent operation at anchor when you take our extended Power Pack. We include solar panels as standard on the coachroof of every model and these can generate several kilowatts of power in the heat of a sunny summer’s day. But of course, the technology is still improving, driven by advances in the automotive and renewable worlds.

When I joined this company, the photovoltaic panels on top of the roof were rated at 280W. Now we use 450W panels and they are already talking about 500-520W. In just two years, that’s an almost 70 per cent improvement in the performance for the same area.

The same thing is happening with batteries. And this is what we really need, because we need to push 10 tonnes of boat through a liquid, which requires much more energy than just rolling wheels on a flat surface.

(Greenline owner) Vladimir Zinchenko is obsessed with innovation, so he’s always trying to push the boundaries. We are always evolving, and this is what makes this company special. We fear no competition, because we’re always moving. So, the brands that follow our lead are always going to be chasing. On the other hand, they can only help us in spreading the word of alternative
