Silent, simple, sustainable navigation.
Manufacturer of ultra-quiet electric canal and river boats designed for low-speed, zero-emission inland waterway navigation.
OUR MISSION
Silennis is a Basque Country electric boat maker whose entire design philosophy centres on putting the passenger back in touch with their surroundings. The S010 and S050 models are built for calm inland waters — rivers, canals, lakes — where their near-silent operation, absence of fumes, and licence-free handling make them the natural choice for rental fleets, eco-tourism operators, and private owners. Solar panels and wind-charging options are built in to minimise grid dependency.
WHY SILENNIS
The compact S010 (3.95 m, up to 7 passengers) is classified for licence-free operation, removing the regulatory barrier for rental operators and recreational users on inland waterways.
At 3.95 × 1.85 m, the S010 fits on a small trailer and occupies a standard 5 × 2.3 m parking space — making transport, launch, and storage straightforward without marina infrastructure.
Silennis integrates solar panels and mini wind turbines alongside shore-power charging, enabling operators in remote or off-grid locations to maintain fleet readiness without a fixed electrical connection.
