Written for petrol: when European boating rules do and do not cover electric craft

Most of Europe's boating rules were written when "motor" meant petrol. Some lawmakers wrote exactly that: a ban on craft driven by an internal combustion engine. Others wrote about the craft itself, whatever moves it.

That difference decides where an electric boat or board may go. Under the first kind of rule, an electric craft can fall outside the ban altogether. Under the second, a battery changes nothing.

We read the definitions in the laws and byelaws we have covered so far. Here is how they line up, and what to do when the wording leaves the question open.

Two kinds of rule in the line-up

Every rule on this page falls into one of two groups:

• Rules written around the engine. They ban or regulate craft with a combustion engine. An electric craft does not match the wording.
• Rules written around the craft. They regulate jet skis, motorboats or boards by type, size or drive, such as a water jet. An electric craft is caught like any other.

The wording is the starting point, not the end. Authorities interpret their own rules, and a few are already rewriting old ones.

Written for petrol: where electric is not caught by the wording

Hungary: Balaton, Velence and Fertő

Hungary's water transport act, § 58 (1), bans small craft and boats "driven by an internal combustion engine" on the whole of Lake Balaton, Lake Velence and the Hungarian part of Fertő, and on parts of Lake Tisza and the Ráckeve Danube branch. The government office's 2026 permit information quotes the ban and does not mention electric motors.

Under that wording, an electric boat is not caught. We have not been able to confirm how the navigation authority applies it to fast electric craft. More in electric boat rules in Hungary.

The Lake District's small lakes

Clause 3(c) of the small lakes byelaws says a power driven vessel "means any vessel propelled by an internal combustion engine". The ban covers 20 lakes and tarns, including Bassenthwaite Lake, Buttermere, Grasmere and Wastwater. Electric boats are not caught by the current wording.

This is the clearest example of a rule about to change. In a consultation discussed on 10 December 2025, the National Park proposed changing the definitions to cover electric motors too, with possible exemptions at limited speeds (consultation extract). See electric boat rules in the UK.

Austria: the waterbike definition and the lake bans

Austria's federal shipping act defines a waterbike as a craft under 4 m with a combustion engine and a jet pump as its main drive, as quoted in Lower Austria's waterbike information sheet. An electric craft with a water jet does not match that wording, but we have not been able to confirm how authorities classify one in practice.

Several Austrian lake bans also target combustion engines. On Attersee and Traunsee, the summer and night bans apply to combustion engines, and hybrids count as combustion (Oö. Seen-Verkehrsverordnung 2005). The same regulations often cap electric power, so electric is allowed but small. See electric boat rules in Austria.

Czechia: 122 waters

Czech Decree 46/2015 bans vessels with combustion engines, hybrids included, on 61 reservoirs and 61 river stretches. The decree does not regulate pure electric motors. See electric boat rules in Czechia.

Written for the craft: where a battery changes nothing

Sweden: the jet ski certificate

Sweden's 1993 ordinance on where jet skis may ride defines them by their combustion engine, and so does the 2016 act on recreational craft. The newer certificate law, in force since 1 May 2022, does not. It defines a jet ski as a craft under 4 m, driven mainly by a water jet and ridden on rather than in (Lag 2021:626). An electric jet craft needs the certificate. See electric boat rules in Sweden.

Germany: jet ski zones

Germany's Wassermotorräder-Verordnung defines jet skis by type, naming "Jetski", "Wasserscooter" and similar craft, with no reference to the drive (WasMotRV). Electric jet skis are held to the same zones and hours on federal waterways. See electric boat rules in Germany.

Denmark: boards count too

The Danish Maritime Authority describes its jet ski certificate as covering similar craft, naming electric surfboards and jet boards. Riders need the certificate, insurance and 300 m of distance from the coast. See electric boat rules in Denmark.

Switzerland: banned either way

Swiss rules ban motorised craft under 2.5 m and motorised surfboards. The Federal Council has said the jet ski ban covers electric ones (Blick, 2023), and the Federal Supreme Court upheld a fine for riding an eFoil on Lake Geneva (World Radio Switzerland, 2022). See electric boat rules in Switzerland.

Local bans that name boards

Some local rules name electric craft directly. The district of Miesbach in Bavaria bans motorboats on Tegernsee, Schliersee and Spitzingsee and names electric foil boards as banned too (Landratsamt Miesbach).

The comparison

Do not paddle out on wording alone

A rule that does not mention electric motors is not a written permission. Three things can still catch you:

1. Interpretation. The authority decides how its rule applies. Ask for a written answer about your specific craft and keep it with you.
2. Other rules. A lake may ban combustion engines and cap electric power at 500 W in the same regulation. Licences, age limits and speed limits apply as usual.
3. Change. Rules written for petrol are being revisited as electric craft multiply. The Lake District is one example. Expect more.

Our verdict: read the definition first

So, does a battery get you in? Sometimes. Where lawmakers wrote about combustion engines, as in Hungary, Czechia and the Lake District, electric craft currently fall outside the ban's wording. Where they wrote about the craft, as in Sweden, Germany, Denmark and Switzerland, a battery changes nothing.

The habit that saves a wipeout is simple: find the definition in the rule, check whether it names an engine or a craft, and ask the authority when it is unclear. Then paddle out.
