The Vessel
A virtual bridge,
built in carbon
The OBLUE FERRY 12E is the world's first commercial, emission-free, autonomous passenger ferry — a 12-metre carbon fiber catamaran linking Södermalm and Kungsholmen across Stockholm's Riddarfjärden.
Christened on 8 June 2023, the first FERRY 12E is operated by a Nordic mobility operator — with a safety operator on board in the first phase and a clear roadmap to shore-supervised, unmanned operation.
- Carbon fiber / vinylester sandwich catamaran
- Integrated autonomous navigation suite
- Four electric pods, 188 kWh battery — 15 hours daily
- Double-ended layout, boarding on both sides
“A network of virtual bridges
across the city's water.”
Design Highlights
Autonomy, proven in service
All-Electric Pod Propulsion
Four electric pods and a 188 kWh battery pack give fifteen hours of daily operation — silent, zero-emission and inexpensive to run.
Solar Roof
The full-width rooftop array feeds the vessel's electrical loads — free energy harvested over every crossing.
Carbon Fiber, Double-Ended
A light, stiff carbon sandwich catamaran with identical ends — no turning basin needed on a tight city route.
On Board
An open deck,
a panoramic view
Twenty-five passengers ride a bright, open deck wrapped in floor-to-ceiling glazing — hop on, hop off between Södermalm and Kungsholmen.
General Arrangement
One open deck,
both ends forward
Double-ended deck plan: boarding gates port and starboard at both ends, helm amidships, machinery below — no bow, no stern, no turning.
In Service
Running the
Riddarfjärden shuttle
Since 12 June 2023 the first FERRY 12E has shuttled between Södermalm and Kungsholmen — up to 120 crossings a day, fifteen hours daily, every fifteen minutes at full rhythm.
