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 a premium day boat drawn as an electric boat from the first sketch. There is no combustion option in the catalog at all.
That position came from geography long before it became a selling point. The boats are built 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.
The lineup is deliberately narrow. The yard would rather build a handful of models carefully in small series than many on a line, and thinking of itself as a small workshop beside a lake is what separates it from the volume manufacturers. For a buyer this cuts both ways. Build slots are limited and lead times are longer than they would be at a large brand, but you get more say in the details and a boat that is not on every mooring in the harbor.
In recent years the brand has moved further into outright luxury too. Industry analysis notes that premium names from the car world keep pushing into boating, and the joint limited series from ABT, a name that made its reputation on high-performance cars, is one of the more visible examples of the trend. 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 actually intend to use it. The next two sections are about exactly that.
The models
The range centers on the flagship M 800, a pure-electric day boat with clean Austrian design. Treat the price with some care, because published sources disagree. Budget for a spread of roughly €110,000 to €200,000, depending on configuration and on the motor and battery package.
Configuration is not marketing filler here. The final figure is driven mostly by the drivetrain and battery you choose, the deck equipment and the level of finish. The same hull can be specified as a relatively plain boat or as something considerably more lavish, which is exactly why the figures floating around vary so widely. Take the bracket above as a rough guide rather than a price list, and have the yard or an official dealer quote the build you actually want.
Above it sits the ABT x Marian M 800-R: a limited series in strictly capped numbers, with up to 450 kW of peak output (around 600 hp) and a price of about €450,000 excluding VAT. 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. Whether you can get one at all tends to come down to demand and availability, the way it does 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. For most people interested in the brand, the M 800 therefore remains the realistic way in.

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 top up at the berth, once the day is done or between two outings, never somewhere along the way. Owners who keep the boat plugged in where it lives largely stop thinking about charging at all. It is full in the morning.
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.
- 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 small yard building in small series, 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. If you want to look more widely first, similarly sized electric day boats built for lake work also come from Alfastreet in Slovenia.
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. What works on an alpine lake transfers with almost no adjustment to a reservoir, a wide river or a sheltered coastal bay.
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. The larger boat shows also list more electric boats every year, in some cases with on-water demos. 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.
