How a “Flying Ferry” is Transforming Stockholm’s Waterways



Commuters in Stockholm have gained a novel way to cross the Swedish capital — a flying electric ferry. Built across 14 islands, Stockholm is naturally suited to waterborne transportation. Yet, relatively slow journeys and infrequent departures led many to navigate via the city’s more than 50 bridges instead. Diesel-run ferries accounted for nearly half of the region’s total public transportation emissions. Then came the introduction of the hydro foiling Candela P-12 Shuttle, described by its manufacturer as the world’s fastest electric passenger vessel. Operating between the suburb of Ekerö and central Stockholm, the ferry has cut travel times from an hour to just 30 minutes. Carbon dioxide emissions have also been slashed by around 94% compared with diesel vehicles. Wing-like carbon fiber foils mounted beneath the hull generate lift as the boat gains speed, raising it above the water’s surface. By reducing contact with the water, drag drops dramatically, enabling higher speeds, smoother travel, and significantly lower energy consumption. This enables long-range and high speed on battery power alone. An onboard computer system constantly adjusts the angle of the foils in real time, using sensors to keep the vessel stable as it “flies" above the water. Noise levels decrease, too, with sound measurements showing the ferry to be as quiet as a car traveling at 27mph, and barely audible from 82 feet away. Germany, India, the Maldives and Thailand are among the countries who have announced plans to order similar vessels in 2026.
