The 7.5 kW line: electric boat rules in Germany

Germany likes its rules written down, and its boating rules are no exception. A licence threshold measured to two decimals, registration marks with a minimum letter height and a separate ordinance for jet skis.

For electric boaters, one number stands out. Since 1 January 2023, Germany has had a lower licence limit for electric motors than for petrol ones. Germany is the only country we know of in Europe to do that.

We went through the rules so you know which motor you can run without a licence, where it needs a number on the side, and which lakes want a permit first.

Paddle out under 7.5 kW: the licence

A Sportbootführerschein, the German boat licence, is required:

• for electric motors above 7.5 kW,
• for combustion engines above 11.03 kW, which is 15 PS.

The electric limit was cut from 11.03 kW to 7.5 kW on 1 January 2023, with no transition period. The reasoning given was that electric motors are more efficient and have more torque, so the same rated power accelerates a boat harder. Owners of electric boats between the two limits needed a licence from one season to the next.

The minimum age to drive a motorboat on federal inland waterways is 16. A narrow exception allows 12-year-olds with a water sports club card to drive boats up to 5 m with no more than 3.68 kW on certain rivers.

If you are buying for licence-free use, check the motor's rated power on its plate and stay at or below 7.5 kW. Our buyer's guide to electric outboards sorts motors by power class.

Numbers on the side: registration marks

On federal inland waterways, including the Rhine, Mosel and Danube, small craft under 20 m need an official registration mark. The exemptions include:

• human-powered craft and dinghies,
• sailing boats without a motor up to 5.50 m,
• motorboats with no more than 2.21 kW.

Exempt boats still need identification: the boat's name on the outside and the owner's name and address on the inside. Marks are at least 10 cm high, permanent and in a contrasting colour.

Think of it as the locals wanting to know whose board is in the line-up. A 3 kW electric outboard already puts you over the limit.

Jet skis: zones only

Germany handles jet skis with a separate ordinance, the Wassermotorräder-Verordnung. On federal inland waterways, riding is banned except in zones released by sign E.22. The released zones are published in the Verkehrsblatt.

In those zones:

• riding is allowed only from 07:00 to 20:00, between sunrise and sunset, with visibility over 1,000 m,
• the craft needs a kill switch that stops the engine or slows it to circling speed if the rider falls off,
• riders wear a lifejacket with at least 50 N of buoyancy,
• launching is allowed only from paved slipways or by crane.

You may ride the shortest route from the launch to a released zone.

The ordinance defines jet skis by type, not by engine. Electric craft are covered the same way as petrol ones. On the water, the locals do not care what is under the seat.

Lakes: every state sets its own line-up

Federal rules cover the federal waterways. Lakes are mostly a matter for the states, and the rules vary widely.

• Bavaria. Motorboats on many lakes need a permit from the district office. Combustion permits are generally issued only on Starnberger See and Ammersee, with caps of 280 and 150. Electric boats can get permits on lakes open to motorboats.
• Tegernsee, Schliersee and Spitzingsee. The district of Miesbach bans motorboats and names electric foil boards as banned too.
• Other states. Edersee and Diemelsee ban combustion engines. Steinhuder Meer allows electric motors up to 10 hp on boats up to 7.60 m.

Alcohol and safety: avoid the wipeout

Alcohol

The limit is 0.5 per mille on inland waterways and at sea, and 0.8 per mille on Lake Constance. From 0.3 per mille, you can be judged unfit if you show signs of impairment. From 1.1 per mille, it is a criminal offence. Fines between 0.5 and 1.09 per mille run from 350 to 2,500 euros inland and from 750 to 2,500 euros at sea.

Lifejackets

Jet ski riders must wear one. For other recreational boats, we did not confirm a general requirement to wear a lifejacket. Wear one anyway.

Charging after the session

Germany has a growing network of marina chargers, particularly in Brandenburg and on Lake Constance. See the charging map for Germany and our guide on how to charge an electric boat.

Our verdict: know your kilowatts

So, how electric-friendly is Germany? Very, as long as you know your numbers. Under 7.5 kW you need no licence, and many lakes that are closed to petrol boats welcome a small electric one, sometimes with a permit.

The traps are specific. Electric motors get a lower licence limit than petrol, a boat above 2.21 kW needs a registration mark on federal waterways, and electric jet skis are held to the same zone rules as petrol ones. Check the plate, check the lake, then paddle out.
