An alpine gem nestled between unspoilt nature and historical heritage
Nestled between mountains and crystal-clear waters, Lake Annecy is an exceptional location for gentle sailing. Weenav takes you on a journey to discover this iconic site, a symbol of a rapidly changing boating industry.
Located in Haute-Savoie, in the heart of the French Alps, Lake Annecy is often described as ‘the purest lake in Europe’. Surrounded by breathtaking landscapes, it attracts thousands of visitors every year who come in search of nature, water sports and relaxation. This iconic location, both fragile and precious, perfectly embodies the challenges of responsible tourism and sustainable navigation.
An exceptional natural heritage
Lake Annecy was formed around 18,000 years ago following the melting of the Alpine glaciers. Measuring 14.6 kilometres long and 3.2 kilometres wide, it is fed by several mountain rivers, including the Thiou, Laudon and Ire. Its remarkable water quality is the result of ambitious environmental policies implemented as early as the 1960s.
Today, the lake is a model for biodiversity conservation and water management. Constant vigilance is exercised to limit pollution, regulate navigation and preserve sensitive areas.
A variety of water sports activities accessible to all
Lake Annecy offers a multitude of water sports activities, accessible to families, sports enthusiasts and nature lovers alike:
- Boat trips: numerous boats ply the waters of the lake, offering tourist cruises or independent excursions.
- Water sports: paddleboarding, rowing, sailing, wakeboarding or water skiing – water sports enthusiasts will find everything they could wish for here.
- Swimming: thanks to its well-equipped beaches and pleasant summer temperatures (up to 24°C), the lake is perfect for swimming.
- Diving: the clear waters allow you to explore the seabed and some underwater curiosities.
In light of the rise in popularity of these practices, electric boating appears to be an ideal alternative, combining performance with respect for the natural environment.
A pilot site for greener boating
Haute-Savoie is currently particularly committed to energy transition, especially in terms of water transport. Regulations are changing to limit noise pollution and emissions. Lake Annecy is thus becoming a testing ground for carbon-free navigation solutions.
This is where Weenav comes in, offering electric propulsion systems tailored to the needs of both individuals and professionals. Our quiet, emission-free motors allow you to navigate in harmony with the lake's unique environment.
Weenav and its committed partners
By collaborating with local stakeholders committed to preserving their territory, Weenav is part of a concrete and responsible transition process.
Our ambition: to enable everyone to fully enjoy the pleasures of water while respecting ecological balance.
Some partners, rental companies and tour operators are beginning to take an interest in electric motors or are testing new, more sustainable navigation solutions. This gradual approach is paving the way for more environmentally friendly nautical tourism.
Among them, NAVITIS, a committed player in electric propulsion in Haute-Savoie, is playing a leading role in the energy transition of Alpine lakes. As an electric shipyard integrated within the ELTIS group, NAVITIS designs complete solutions, from high voltage to motorisation, including electrical networks and charging stations. They support individuals and professionals in decarbonising their fleets, whether for recreational boating or passenger transport.

A different way to navigate is possible... starting today.
Lake Annecy proves that tourism and ecology are not incompatible. Thanks to innovation, local commitments and the willingness of boaters to change their habits, a new way of enjoying water sports is emerging.
At Weenav, we are convinced that the future of boating is electric. And on the crystal-clear waters of Lake Annecy, this vision is becoming a reality.
