The brand
Alfastreet Marine is the former name of Alfastreet Yachts, a Slovenian boatyard that Pockaj d.o.o. runs from Sežana, a small town near the Italian border. The brand was never aiming at the open ocean. Its range combines electric lake boats and day boats with inboard and outboard models, and the focus on sheltered water shapes everything else about them. The yard calls its boats luxury; we would put them in the upper mid-range. Alfastreet is not fighting for the top luxury tier the way Frauscher does. It sits a step below, and its boats are still built to a demanding standard of finish.
The yard pitches its electric versions at lakes and quiet waters, including the ones where combustion engines are restricted or banned outright. An older German-language page on its former site tied the electric range to ever stricter rules for motorboats on inland lakes, and the Energy 18, one of the three boats in its 2014 fleet, already ran on electricity. Quiet electric propulsion is the only sensible way onto water like that. Reservoirs, drinking-water lakes and protected inland waters in many countries limit engines the same way. Rules differ by country and often by individual lake or stretch of coast, so check what applies where you plan to keep the boat before you fall for a specific model.
The more useful question is what that upper mid-range position buys you. You do not have to settle for a mass-produced entry boat, and you do not need the budget for something built around one owner’s wish list. Alfastreet works the ground in between, where materials, joinery and comfort are already a level up but the boat has not turned into a prestige object with a bespoke price tag. For a lot of lake buyers that middle is where they want to be, and it is a harder place to build in than either extreme, because you have to decide which corners cannot be cut.
The yard itself does not draw a hard line between lake and sea. Its About page talks of the best experience on any body of water, every model in its electric series is also sold with a combustion engine, and every model on its site carries CE design category C, the category for wind up to force 6 on the Beaufort scale and a significant wave height of up to 2 meters. The 28 Cabin Electric sits on a displacement hull. A boat designed for calm lakes behaves differently from a sport boat built to punch through chop. It is not fighting the sea state, so the priorities shift to quiet running, comfort at cruising pace and low maintenance. That happens to be what most people want after a long week when they finally get to the water.
If the term day boat is new to you, it describes a boat measured in hours rather than nights: seating for a group, a swim platform, somewhere to stow a cooler and towels, and no serious sleeping accommodation below. You take it out for an afternoon and come back to the same berth. That pattern is precisely why electric propulsion fits the category so well. A day boat rarely needs the range of a cruiser, and it gets used in the places where engine noise is least welcome. Alfastreet's cabin models stretch that definition. The yard's configurator lists two cabin beds for the 23 Cabin Evo, and its 28 Cabin Electric page describes a king-sized bed and a private bathroom.

The clip comes from the yard's own Alfastreet Yachts channel and shows the 28 Cabin, which the maker lists at 8.6 meters (9.8 meters overall), 4,300 kg empty and up to 12 adults. Photographs and the rest of the lineup are on alfastreet-yachts.com.
Models
The yard's current site, alfastreet-yachts.com, has ten model pages from 6.6 to 10.1 meters overall, split into inboard, outboard and electric series, and by the yard's own count half the boats it has sold were electric. Four models make up the electric series: the 21 Open, the 23 Cabin Evo, the 28 Cabin and the 28 Open. The old domain is another story. When we opened alfastreet-marine.com on 12 September 2026 the domain was parked and offered for sale, a short script forwarding to a GoDaddy sales page, and neither alfastreetmarine.com nor alfastreet-marine.si resolved. The yard had moved, not closed. Archived captures show the old domain forwarding to alfastreet-yachts.com in January and March 2024, and the brand now trades there as Alfastreet Yachts from its old address in Sežana. Unless we say otherwise, the figures below come from that site, read on 5 October 2026.
Two electric models stand out. The compact, open 21 Open Electric (6.3 m long, 6.6 m overall) sits at the small end, and the larger 23 Cabin Evo Electric (6.9 m, 7.8 m overall) adds a cabin. Between them they cover the two ways most people use a boat like this. The older 18 Open is no longer listed; the yard's 2019 specification gave it 5.4 m, or 5.8 m overall.

We print no prices, and the reason is not the one we gave in July. Back then the trouble was that the figures you could find publicly contradicted one another. Now it is simpler. Neither the yard's current site nor its online configurator shows a price (both read on 5 October 2026), so ask the yard, or a dealer who has sold the brand, for a written offer that lists motor, battery and equipment line by line. Among the electric boatyards we follow, RAND and X Shore printed prices across their ranges when we checked that day, and Marian showed a starting price on most of its German model pages. Alfastreet's old site did print starting prices in 2019, but they left out tax and the engine, so they are no guide to what a boat costs now. That leaves positioning, and even that is our own reading: we place the boats in the upper mid-range, while the yard sells them as luxury.
With ten model pages on the yard's current site, one rule keeps things simple. Do not shop by length, shop by use. The shorter open boats are at their best on spontaneous, low-effort outings, while the longer cabin models earn their keep on full-day programs where protected space matters. Equipment varies enormously between configurations too. The same model can feel minimalist in one specification and lavish in another, which is why an hour on board tells you more than any spec sheet.
Stepping up a size class changes more than the number on the transom. A longer boat weighs more, needs a wider berth, is harder to move by road, and takes an extra pair of hands to dock comfortably in a crosswind. None of that is a reason to buy small, but all of it is worth checking against your marina and your towing vehicle before you sign anything. Measure the slip and the approach in advance, not on delivery day.
Buy for the next few seasons rather than for last summer. If two of you go out today but the family or the circle of friends is about to grow, a slightly larger model with more room is the easier long-term choice. The reverse holds just as firmly: if the honest answer is that you take short, light runs and rarely stay out past dinner, a simpler and smaller boat will give you more of what you actually enjoy, without paying for paper capability you never call on.
Open or cabin? How to decide
The two models above, the open 21 Open Electric and the 23 Cabin Evo Electric with its cabin, mark the two directions most lake buyers choose between. Size is rarely the real question. What matters far more is how, with whom and for how long you spend your days on the water. A few practical questions sort it out quickly:
- Who comes with you: with a group of adults, the generous open deck wins every time; with small children or a mixed-age crowd, shade and a sheltered corner count for considerably more.
- How long you stay out: a few hours of swimming asks nothing of a boat beyond seating and a ladder, but on a full day, or a run that stretches into the evening, somewhere to retreat under a roof starts to feel like a luxury you would rather not give up.
- Sun or shade: if swimming and sunbathing are the point, the open layout is the better fit; if you want to stay out through hot afternoons, the covered space is where everyone ends up sitting.
- Storage and berthing: a shorter, lighter boat is simpler to store and to move, while the larger cabin model needs more room and often a bigger berth.
- Comfort or simplicity: more enclosed space and more equipment means more comfort, and also more things that want looking after.
If your boating day is usually a short, unplanned hop between a beach and a quiet bay, the open boat is liberating in its simplicity: step on, cast off, swim, come home. If instead you like whole days on the water, occasionally sit out a shower, or simply enjoy having a protected spot on board, the cabin version gives you noticeably more for the money.
There is no answer that is right in the abstract. The right one falls out of your own habits, which is exactly why it pays to try both layouts before deciding. A few minutes of a demo ride usually settles the argument better than weeks of comparing photographs.
A day on board
What does an electric lake boat give you on an ordinary summer day? The most obvious difference is the quiet. With no engine drone and no exhaust smell, water, wind and reeds sound completely different. Plenty of people go to a lake looking for exactly that calm, and a quiet electric drive takes none of it away from them.
Picture a typical day: a slow morning run with coffee across water still flat as glass, an anchor stop at midday in a sheltered bay with a swim and lunch on board, an easy crossing to the far shore in the late afternoon, then a quiet return to the harbor at sunset. A boat in the day boat class is made for that rhythm: big enough for a full-day program, small enough that going out never turns into a project.
No two days have to look alike, either. On a weekday morning the boat belongs to you and the silence; on a weekend afternoon it fills up with friends; on a calm evening it makes a fine platform for a sunset run with guests. That flexibility is what keeps a well-chosen lake boat interesting over years. It is not locked into one scenario but changes with the season and with whoever is on board.
Beyond the quiet, electric propulsion brings solid practical advantages on a lake: no fuel smell on deck, next to no vibration, and generally fewer moving parts asking for your attention. The charging routine that goes with it is simpler than most people assume. If the boat lives where the power is, you plug in at the berth after the outing and let it charge there. How long a full charge takes depends on the battery and the charger, and the yard's model pages and brochures give a figure for neither, so get both in writing. Range, though, is not a fixed figure: a charge lasts far longer at a relaxed cruising pace than at sustained full throttle, the same split you already know from an electric car. We break down what charging, range and day planning really demand in the electric boat guide. Shorter runs on a lake are the profile these boats suit best.
Where an Alfastreet fits
Start with geography. Sežana, where the yard has its headquarters, sits in western Slovenia, just short of Trieste, which puts it inside the EU and within a day’s drive of a large part of central and southern Europe. For European buyers that matters in daily life as much as at purchase: a factory visit or a service question is a different proposition when the yard is a drive away rather than an ocean away. If you are buying from further afield, the question simply changes shape. What counts then is not the distance to the factory but whether there is a dealer or an authorized service partner within reach of your marina, and that is a question to ask before the deposit, not after.
Then the size. The current lineup runs from 6.6 to 10.1 meters overall, the day boat class, not too small for a full family day and not so large that berthing or handling becomes the hard part of the outing. By the yard's figures the 21 Open, 23 Cabin Evo and 25 Cabin Evo take 8 adults, and the 28 Cabin, 28 Open and 32 Cabin take 12.
Finally the propulsion. On a great many inland lakes, private combustion-engine boats are heavily restricted or not permitted at all, while electric drives have a far easier time getting approval. That is the environment these boats grew up in. What it means day to day, and what to check before you buy, is collected in our electric boat guide. A builder that already had an electric boat, the Energy 18, among the three in its 2014 fleet starts with a real advantage on that kind of water, with more than a decade of electric models behind it.
Buying, service and ownership
The single most useful piece of advice before buying is also the simplest: get on board and drive it. A demo ride shows you in minutes what no photograph and no data sheet will: how easy the boat is to steer, how much deck space is really left once people are sitting on it, how quiet it runs, and which layout matches your habits. Electric boat dealers and the bigger boat shows are where those chances come up. Take one.
Support after the sale deserves as much thought as the boat itself. A lake boat only earns its price if you can use it without worry for years, and that needs a reliable backstop: servicing, spare parts and someone competent to call. Those things move faster and with less friction when the yard or an authorized partner is genuinely reachable from where the boat lives. It is an easy point to underrate while you are looking at photographs of the deck, and it stays with you for the whole time you own the boat. For a used boat, ask the seller for copies of the owner's manual, the motor and battery data sheet and the original warranty terms before you pay, and check anything missing with the yard, which lists a phone number and an email address on alfastreet-yachts.com. A seller who has the papers saves you weeks of searching; one who does not tells you something about the boat's history.
A few practical owner questions are worth settling early. Where will the boat live and how large does the berth need to be? Where and how will you charge, and does the pedestal at your slip have enough capacity for a boat in this class? What happens outside the season? Winter storage, maintenance and spring launch still apply to an electric boat, only on a slightly different rhythm, with battery care taking the place of the engine routine. Local dealers and the electric boating community will get you a long way on all of it. You do not have to work it out alone.
If you are new to the subject, give yourself a wider view before you commit. Compare Alfastreet against other brands such as Marian and Greenline to see where the Slovenian yard sits in the market, and look at the foiling boats too if efficiency at higher speeds interests you. For the fundamentals, from drivetrains to the practicalities of ownership, our electric boat guide is the place to start.
