The brand
Marian is a boatyard in St. Wolfgang, a small town on the Wolfgangsee in the Austrian lake district. Most builders start with a gasoline hull and add an electric version later. This yard works the other way around: every boat it makes is drawn as an electric boat from the first sketch, and all but one are day boats. The exception is the Capriole 700, which Marian calls the only cabin boat in its portfolio, with a cabin that converts into a sleeping area. There is no combustion option in the catalog at all.
That position came from geography long before it became a selling point. Final assembly happens on the Wolfgangsee (the M 800-R site places Marian’s production roots in Romania), in the middle of a lake region where combustion engines are restricted or banned outright on many alpine lakes. The yard therefore builds for exactly that water, where quiet, emission-free running is not a bonus feature but a requirement. Every model starts from the same picture: an elegant boat you take from one shore to the other for a swim, for lunch, for the last hour of light.
The term day boat deserves a moment, because the yard’s whole philosophy rests on it. This is not a cabin boat with berths for the night. It is a boat built for hours rather than days: open deck space, seating for a group, a swim platform, short crossings, and a return to the same mooring in the evening. That use pattern is what makes electric propulsion sensible here in the first place. A day boat rarely needs a cruiser’s range, and it spends its life in the places where engine noise is least welcome.
Marian calls itself a family business, and the menu on marianboats.at lists nine models, from the 5.80 m Eclipse 580 up to the M 800 and its variants. Each M 800 is made by hand, the model page says, with colors, accessories, materials and equipment that can be customized for each buyer. That gives you a real say in the details and a boat that is not on every mooring in the harbor. Marian’s model pages name no build slots or lead times, so have the delivery date written into the quote.
In recent years the brand has moved further into outright luxury too. The clearest sign is the limited series built with ABT Sportsline, a company known for customized Audi, VW and Lamborghini cars. In November 2025 Marian said the partnership was in its third consecutive year. Frauscher, another Austrian yard, has taken a similar route with its Porsche partnership.

Why pure electric
Building nothing but electric boats is an engineering decision, not a badge. Nothing in this range is a gasoline design with a battery pushed into it afterwards. When a boat is drawn for battery power from the beginning, weight distribution, deck layout and hull shape all follow from that choice, and the drivetrain stops being a compromise. It becomes the starting point. On a day boat meant for lake use that goes double, because the question here is not how far you can push across open sea. It is the quality of a calm day on the water.
The difference you notice first is the quiet. With no engine droning under the deck and no exhaust drifting across the cockpit, being afloat feels different: you hear the wake and the shoreline, conversation carries at normal volume, and nobody swimming off the stern is breathing fumes. Electric propulsion also delivers its power evenly, with little vibration and no lag, which makes maneuvering more predictable. Docking in particular gets easier when thrust arrives the instant you ask for it rather than after a gearshift and a rev climb.
A good deal of routine servicing simply disappears. No oil changes, no fuel filters, no end-of-season ritual built around an engine, and far fewer moving parts to wear out. What replaces all of that is a different sort of attention: battery care, cell health over the years, and the electronics that manage the pack. Different work, not more of it, and most of it happens on a schedule you can plan around.
Stay realistic all the same. An electric boat does not run for free, it runs differently. Charging access, shore power at your berth and the weight of the boat shape daily life with it at least as much as the peak output on the spec sheet does. Work out early how and where you intend to use it, because those two answers decide the battery package you order and the shore power you need in place at your berth before the boat arrives.
The models
The range centers on the flagship M 800, a pure-electric day boat with clean Austrian design. Marian shows a price for it on both language versions of the model page. The English page on marianboats.at prints “from” and the German one “ab”, followed by €226,000 excluding VAT, read on 5 October 2026. The 2026 equipment list linked from the page names an 80 kW motor with a 63 kWh battery and a charger of up to 22 kW as standard equipment. It prints no prices, so ask whether the starting price covers that package.
Configuration is not marketing filler here, and the yard’s own figures do not quite agree with each other. The box at the top of both language versions of the M 800 page promises 73 km/h, 220 kW and 126 kWh, and both spec tables list motors of 80, 120, 160 and 220 kW. On the battery they part ways. The German table stops at 126 kWh, while the English one reads up to 220 kWh, a figure found nowhere else on either page. The range calculator on the same page still offers lithium packages with motors of 60 to 150 kW and up to 125 kWh, and the 2026 equipment list tops out at a 200 kW motor. The yard explains none of these gaps. The final figure is driven mostly by the drivetrain and battery you choose, the deck equipment and the level of finish. Take the starting price as just that, a starting point, and have the yard or an official dealer quote the build you actually want with motor and battery capacity written out in numbers.
Above it sits the ABT x Marian M 800-R: a limited series built with ABT Sportsline in 20 units, with 450 kW of peak output in ABT Mode (around 600 hp), 320 kW continuous and a 148 kWh battery, per the spec pages on en.abt-marian.com, checked on 5 October 2026. ABT publishes no price. That is collector territory, an electric sport boat from the very top of the segment.
The limited run is a statement in itself. The M 800-R is not simply the quicker boat; it is a collector’s item where rarity and exclusivity weigh as heavily as output. ABT gives the run as 20 units worldwide, a number fixed in advance, as with any capped series. Worth keeping in perspective, too: peak output is a headline number rather than a description of daily use. You spend most of your hours afloat using a fraction of it, and how a boat behaves at cruising speed matters far more than what it does flat out. Between the two, the M 800 therefore remains the realistic choice for most buyers. The brand itself starts far lower, with the Eclipse 580 listed from €41,000 excluding VAT (read on 5 October 2026).

Charging and range
Range is the first thing anyone asks about an electric boat, and the honest answer is that it depends. How far you get is set by speed, load, wind and waves, and of course by the battery package you specified. A single number would mislead you. The good news is that real use rarely looks like a range test. You cover short legs, spend a lot of time at anchor, swim, eat lunch and then move on again.
That unhurried rhythm with plenty of stops is where electric propulsion is at its best. Relaxed cruising is dramatically kinder to the state of charge than sustained full throttle, and the gap between the two is wider afloat than it is on the road, because drag climbs steeply once a hull is pushed hard. Charging logic differs from a car as well: you usually top up at the berth, once the day is done or between two outings, and seldom somewhere along the way, even though the M 800 equipment list offers a CCS port for charging at up to 120 kW. Owners who keep the boat plugged in where it lives largely stop thinking about charging, provided the berth can feed the charger of up to 22 kW that the list names as standard.
One point gets overlooked more often than it should. A pure-electric boat charges ashore, on the harbor’s infrastructure. Before you settle on a boat, find out what electrical supply your home berth actually has. A dock pedestal sized for a kettle and a fridge will not do the job, and marina upgrades do not happen quickly. Ask for concrete range and charging figures for the configuration that interests you, and ask what the charge time looks like on the supply you will really be using rather than on an ideal one.
What to check before you buy
If a Marian genuinely appeals to you, or a premium electric day boat in general, a handful of questions are worth settling early. None of these are weaknesses of the boat. They are the decisions that determine what ownership feels like once the novelty has worn off.
- How you will use it: short trips and swimming days on sheltered water, or longer and faster runs as well? The answer decides which motor and battery package suits you. Both M 800 spec tables list motors of 80, 120, 160 and 220 kW, and the 2026 equipment list names 80 kW with 63 kWh as standard.
- Berth and charging: is there reliable shore power where the boat will live, and can you charge comfortably at the end of a day out?
- Service and parts: this is a family business that builds each M 800 by hand, so ask before you buy how support, warranty work and parts supply are handled in your region, and who the nearest authorized service point is. Distance from the factory matters more for a low-volume builder than it does for a volume brand.
- Storage and the off-season: think about craning out at the end of the season, winter storage, and the conditions the battery needs while the boat sits idle.
- A trial run: get on board before you decide. Size, comfort and maneuverability read completely differently on the water than they do in a brochure.
- Local regulations: licensing, registration, insurance minimums, speed limits and how close you may run to swimmers all differ by country and often by individual lake or stretch of coast, and they change. Check the current rules for your water before you commit to a boat.
With an electric day boat it pays to look past the purchase price at the total cost across the years you plan to keep it. The drivetrain is simpler, there are fewer wear parts and the fuel bill disappears, which shows up mainly in running costs. Over a longer horizon, battery condition and onboard electronics are what count. Do not forget either that on a premium brand, careful maintenance, a complete service history and a well-judged specification do a great deal for residual value. A Marian is less a means of getting across the water than a way of spending a summer. The best decision comes from being honest with yourself about how many days you will really be out there, and in what style.
Then there is the paperwork. Get the exact technical data in an official quote, and check the current registration and licensing requirements for the water you plan to use. Similarly sized electric day boats built for lake work also came from Alfastreet in Slovenia, though the yard’s own site, alfastreet-marine.com, was forwarding to a GoDaddy domain sales page on 5 October 2026.
Where a Marian fits
Few brands sit as naturally on a lake as this one, which is hardly surprising given where it comes from. The boats are exactly the classic day boat size for a day on the water and were conceived for places where combustion engines are heavily restricted, a description that fits a great many inland lakes and reservoirs around the world. On that kind of water, quiet electric propulsion stops being a niche preference and becomes the ticket in. Our electric boat guide covers the wider market, the brands and the questions worth asking. Much of what works on an alpine lake carries over to a reservoir or a wide river. Salt water is another matter. Marian’s M 800 page says nothing about it, while the ABT site lists saltwater resistance among the additional highlights of the M 800-R, so ask the yard what a coastal berth requires.
If you want to experience a boat like this in person, ask dealers who specialize in premium electric boats; many of them carry several European brands side by side. Marian’s own site also has a form on the M 800 page for booking a test drive. And if you are drawn to something more futuristic still, take a look at hydrofoil boats, which lift the hull clear of the water altogether.
Picture an ordinary summer day. You slide quietly into a bay in the morning, drop the anchor, jump in, run across for lunch and come back into the sunset with no engine noise and no exhaust. That day is what an electric day boat is designed around. Modest distances and an easy pace suit its character exactly. Just remember that local authorities set the rules and the rules do change: check registration and the current requirements for your own water before you cast off.
