Lake Constance is one of the most beautiful yet most fragile bodies of water in Europe. This makes it all the more important that motor sport on the lake is conducted in the most environmentally friendly way possible. For the IBMV, the umbrella organisation for motorboat clubs in Germany, Austria and Switzerland, this issue is right at the top of the agenda.
An open approach to technology rather than bans
At the Annual General Meeting held in Fussach on 10 October 2026, IBMV President Martin Lepple made it clear how the association intends to shape the path towards climate-friendly shipping: by embracing all technologies. “The lake is characterised by a wide variety of propulsion systems – and it is precisely this diversity that is important,” emphasised Lepple. The association is not relying on a single technology, but on the best mix of existing and future solutions.
HVO-100: The climate-friendly diesel is gaining ground
One tangible success in the field of environmental protection is the widespread availability of the HVO-100 biofuel (hydrotreated vegetable oil) on Lake Constance. Almost all Boat refuelling stations Stations around the lake now offer this climate-friendly diesel fuel. HVO-100 can be used in existing diesel engines without the need for technical modifications and reduces CO₂ emissions by up to 90 per cent compared with fossil diesel. For many boat owners, this is the simplest and quickest way to reduce their environmental footprint.
E-mobility on the water is gaining momentum
Electric mobility is also making its mark on Lake Constance: the first charging point specifically for boats has been in operation at the BMK harbour in Langenargen since the start of this year. The charging point enables safe charging at 11 kW and thus represents an important step towards emission-free boating. Lepple sees this as a positive boost for the entire industry – further charging points could follow.
Maritime Service: Volunteering to protect nature and our waters
Another cornerstone of the IBMV’s environmental commitment is the sailing service, which Vice-President Harry Vetter reported on. The member clubs provide this service on a voluntary basis – and with increasing dedication.
The Lake Service promotes water sports in harmony with nature, provides assistance to water sports enthusiasts and is actively committed to environmental and water protection, nature conservation and animal welfare, as well as ensuring compliance with regulations governing shore zones. Vetter expressly thanked the dedicated Lake Service skippers for their tireless efforts.
Summary
The IBMV demonstrates that motorboating and environmental awareness are not mutually exclusive. With the widespread availability of HVO-100, the first electric charging station for boats, and its active ferry service, the association is implementing concrete measures – thereby making it clear that climate-friendly boating on Lake Constance is not a distant goal, but already a reality.
