Electric boat without a licence: what power limits apply in Europe?

In the UK there is no licence requirement for private pleasure craft, electric or not. On the Continent it depends on motor power. In Germany you can drive an electric boat without a licence if the motor delivers no more than 7.5 kW continuous power, just over 10 hp, and you are at least 16. Lake Constance is stricter at 4.4 kW. Austria also draws the line at 4.4 kW, Switzerland at 6 kW.

Why is the German limit lower for electric motors than for petrol engines?

The German pleasure craft licence regulation sets two limits: 11.03 kW (15 hp) for combustion engines and 7.5 kW for electric motors, measured as continuous power (S1) (§ 5 SpFV). The Federal Ministry of Transport confirms both limits for inland and coastal federal waterways and sets a minimum age of 16. One exception is the Elbe in the Port of Hamburg (BMV Wassersport).

Above that power, you need the inland pleasure craft licence (Sportbootführerschein Binnen) on inland waterways (§ 3 SpFV). This also applies on the Rhine.

The limits at a glance

Switzerland has no separate rule for electric drives. The ordinance does not distinguish by type of drive. For category A motorboats, the canton of Bern sets a minimum age of 18 (SVSA Bern).

Do I still need a registration or a licence plate?

Usually yes. Licence-free does not mean registration-free:

• United Kingdom: Every boat on Canal & River Trust waterways needs a licence. On Environment Agency waters such as the Thames, boats must be registered (CRT, GOV.UK).
• Germany, federal waterways: Motorised pleasure craft under 20 m need an official or officially recognised small craft identification mark. This is not a technical approval (BMV).
• Bavaria: Electric boats need an identification mark from the district authority. They are exempt from the technical approval (TÜV). Their permit is unlimited in time, while combustion boats get five years at most (BaySchiffO, naturerlebnis.bayern.de).
• Lake Constance: Every boat with mechanical propulsion needs an approval, including electric boats, with no lower power limit. Boats with a built-in lithium-ion battery also carry the warning sign W012 next to the registration number and on the stern (BSO).
• Austria: Battery-electric boats below 4.4 kW need no approval, except for commercial passenger transport (RIS).
• Switzerland: Boats on public waters need a registration plate and a ship's certificate. Boats under 2.50 m are exempt, but may then only use the inner shore zone (150 m) (BSV).

What if I want to hire a houseboat in Germany without a licence?

Then the charter certificate (Charterbescheinigung) is your route. It lets you skipper a hired pleasure craft under 15 m without a licence after a briefing by the hire company (§ 9 SportbootVermV-Bin). It is only valid on certain waters, such as the Müritz-Elde waterway, the Upper Havel and the Spree-Oder waterway, and the boat may not go faster than 12 km/h (Annex 5, Annex 6). The type of drive makes no difference here.
