The brand
Greenline Yachts belongs to the Slovenian SVP Yachts group, and few names in boatbuilding are tied as tightly to the hybrid idea. Since 2008 the yard has been building cruising yachts with hybrid drivetrains, which puts it among the pioneers of the segment. Most builders only turned toward electric propulsion in the last few years. Here it was the starting point.
One thing is worth settling early. Greenline does not compete in the day boat class at all. The range is built entirely of 39 to 58 foot boats, roughly 12 to 18 meters, and every one of them is a cruising yacht. That is considerably more boat than most people ever handle on an inland lake or in a small coastal marina, so this page is written above all for readers who are already thinking in yacht sizes.
So what does it change when a yard has spent close to two decades building hybrids? Mainly that the hybrid layout here is neither a marketing angle nor an option bolted onto an existing hull. It is the core of the brand identity. Look at a current Greenline and you are not looking at a first-generation experiment but at the present state of a concept that has had time to mature. In electric boatbuilding that counts for a lot, because a good part of the industry is still working out what has been routine at this yard for years.
The second thing worth pinning down is the cruising yacht as a category. A day boat exists so you can spend a few hours on the water and head home afterwards. A cruiser exists so you can live on the water, for days and sometimes weeks. That single difference shapes the whole boat: the size, the layout below deck, the energy the systems draw, the way you run it. With Greenline you are not buying a bigger boat. You are buying into a separate category, and it rewards a different way of thinking.
That distinction also explains why the hybrid idea and the cruiser format fit each other so well. A boat you take out for an afternoon has little use for a second drivetrain. A boat you sleep on, cook on and anchor off for a week has a genuine need for quiet running and for onboard power that does not depend on a machine hammering away in the background. The two halves of the concept were built for each other rather than combined after the fact.

The range and the drivetrain
The lineup runs from the 39 footer up to the 58 foot flagship, and across every size the yachts share one philosophy: the hybrid drivetrain with a full electric mode. On electric power alone you cruise at around 6.5 knots, about 12 km/h or roughly 7.5 mph, in complete silence and with no exhaust. Maneuvering inside a marina, dropping the anchor in a bay, taking a slow lap after dinner: that mode is what the Greenline experience is built around.
The brand's next move is telling too. According to the manufacturer, models from 2025 no longer need a diesel generator, with the battery system taking over the boat's onboard power instead. For specific models and equipment levels it is worth checking what the yard and its dealers are offering right now, since the lineup moves on from one model year to the next.
The logic of a hybrid drivetrain deserves a second look, because the strength of the concept sits right there: you get one boat with two characters. The electric side owns the quiet moments, the harbor maneuver, the approach into an anchorage, the slow run after sunset. The combustion side takes over the moment a longer passage is on the plan and covered distance is what counts. Nothing has to be decided in advance. Which face the boat shows is always settled by the situation.
Six and a half knots reads modestly on paper, and it helps to understand why the figure sits where it does. A displacement hull asks far less of its motors at low speed, and the relationship is steep rather than linear, so a few knots less cuts the power draw sharply. Electric running on a boat this size is only useful because it stays inside that efficient band. Push a heavy cruiser to planing speeds on batteries and the numbers stop working, which is exactly the wall the combustion side is there to get past.
Hybrid running in practice
The hybrid concept becomes tangible once you walk through a typical day aboard. You leave the berth in the morning on electric power. The maneuver runs quietly, with no cloud of exhaust and no jerk in the throttle, and in a tight marina that is a real advantage. You are not filling the neighboring cockpits with fumes, and you can feel precisely how the boat answers the helm. Moments like that are where the electric side plays its strongest card.
As soon as you are in open water with a longer leg to the next bay in front of you, the combustion side of the drivetrain takes over. Now distance and passage time are what matter, not the silence. The two worlds are not an either-or: the boat shows both faces on the same day, and you decide from the situation which one is up.
At the destination the lead role goes back to the electric mode. Close to an anchorage you move slowly and carefully, and that is precisely when it helps that nothing is rumbling below you. Swimming takes the middle of the day, the afternoon belongs to the water, and a quiet lap after sunset closes it out at exactly the unhurried 6.5 knots the electric mode was made for.
The quietest part of a hybrid trip only arrives at night. Because the manufacturer states that onboard energy comes from the battery system on models from 2025, no generator hums through the evening at anchor. The fridge, the lights and the rest of the load simply run. In practice this turns into a planning habit: put the long, fast legs where the combustion side is needed anyway, and save the silent electric running for the places where quiet is the entire point. That deliberate division is the real craft of hybrid cruising.
It also changes how a route reads. Instead of one continuous passage plan you end up with a rhythm of loud and quiet sections, and after a season or two you start choosing anchorages and departure times around it. The part that stays with you is less the technology in the engine room than the way it reshapes an ordinary day.
Who it suits, and who it doesn't
A Greenline is not a mass-market product and has no ambition to be one, which is all the more reason to check honestly whether it fits the way you actually use a boat. It is built for people who go out on the water for days or weeks rather than a few hours, people for whom the boat is accommodation, kitchen and living room in one. If the idea of waking up in a different bay from the one you anchored in the night before appeals to you, you are in the right place.
It works just as well for anyone who puts silence and emission-free running first and goes out looking for calm rather than speed. It gets genuinely interesting for owners planning a berth in a cruising ground with anchorages within a day's run. A cruising yacht that can also travel on electric power alone is a logical choice there, quiet in the marina and quiet in every bay you stop in.
Who is it not for? Anyone after a nimble day boat of a few meters for an afternoon swim or for watersports: this boat is simply too big and too much to run for that. If you get on the water rarely and only for a few hours at a time, you would hardly ever use the thing a cruising yacht is built for in the first place. And if speed or cheap, carefree running is the goal, look elsewhere. A Greenline is the right decision when you actively want the longer, slower, quieter version of life on the water, not when you merely tolerate it.
Cruising grounds and the size question
To be blunt about it, a 12 to 18 meter cruising yacht is far bigger than what most people run on their home water, so a Greenline will not be a realistic option for everyone. If what you want is an elegant 6 to 8 meter day boat, the class that Frauscher and the equally Slovenian Alfastreet work in is a better fit. Greenline becomes interesting once you are already shopping at this size, or once you are planning a base in real cruising water: sheltered bays, short hops between islands, marinas where a quiet approach is appreciated rather than merely tolerated.
The yard's own home water is that sort of ground, which shows in how the boats are drawn. The same reasoning transfers anywhere with protected water and enough anchorages within a day's run, from island chains and calm coastal stretches to the larger inland lakes. On many of those lakes and in protected areas, combustion engines are restricted or banned outright, so a boat that can move silently on electric power works with those rules rather than against them. Rules differ by country and often by individual lake or coastline, covering registration, speed and noise limits as well as engine type, so check your local regulations before you commit to a berth.
For the wider picture of where the segment is heading, our overview of electric boats covers what builders are doing across the market. If what draws you is the flying kind of hull rather than a displacement cruiser, start with the hydrofoil boat guide instead. Those are two different answers to the same question about efficiency: one lifts the hull clear of the water to cut drag, the other keeps a displacement hull and adds a second, quieter way of driving it. Hybrid and electric boats also show up at the major international boat shows, which is still the fastest way to compare hulls side by side.
What to sort out before you buy
Once you are far enough along to be considering a Greenline seriously, a handful of points are worth answering honestly before you commit. Not to put you off, but so that nothing catches you out later. With a boat this size, preparation counts for more than enthusiasm.
- Berth and winter storage: a 12 to 18 meter yacht needs a proper marina berth, plus a plan for both the summer mooring and winter storage. That is a different league from putting a small day boat on a trailer.
- Realistic use: count honestly how many days a year you would spend on the water. A cruising yacht pays back when you genuinely travel with it, not when it sits in the marina.
- Get a quote: public list prices are rare, so always ask for a quote on the specific model with its equipment. The lineup and its configurations change from year to year, so what the yard and the dealer are quoting today is the only reliable reference.
- See it in person: photos and layout drawings only take you so far. Walk the deck, sit in the cockpit, and if you can, run a berthing maneuver on electric power. Everything feels different on board than it does on paper.
- Expectations of the electric mode: the 6.5 knots on electric power are meant for maneuvers and quiet laps, not for getting anywhere quickly. Better to have that clear before you try it than after.
- Rules and running: wherever the boat will live, clarify licensing, registration and the local regulations for that water through official sources first. Requirements vary widely between countries and even between neighboring lakes.
A boat of this size is not an impulse buy but a commitment measured in years. Work through those points beforehand and you sit down at the negotiating table with a clearer head, and that calm, prepared frame of mind is what suits a Greenline best.
