A groundbreaking hydrofoil ferry in Sweden is poised to revolutionize waterborne public transport, offering an eco-friendly alternative for cities with waterways. Candela’s new P-12 vessel, recently unveiled, utilizes cutting-edge technology, gliding silently over the water on carbon fiber hydrofoil wings, significantly reducing drag and enhancing energy efficiency.
The P-12, designed to carry 30 passengers at a maximum speed of 30 knots (56 kph or 35 mph), outpaces other electric passenger ferries. Candela’s hydrofoil technology slashes energy consumption by an impressive 95% compared to diesel ships currently navigating Stockholm’s archipelago.
Testing is ongoing, but the P-12 is scheduled to commence service in July, connecting the Stockholm suburb of Ekero with the city center. The pilot project aims to cut travel time from Ekero to the city center from 55 to 25 minutes. With no wake left behind, the ferry is exempt from speed limits, adding another advantage to its eco-friendly profile.
Candela aims to draw from the success of its smaller electric hydrofoil leisure boat, leveraging onboard technology that adjusts hydrofoils in real-time to compensate for sea conditions. Operating efficiently in waves up to two meters (6.5 feet), the P-12 represents a promising advancement in waterborne transport.
Cities like San Francisco, New York, and Venice are envisioned as potential leaders in electrifying waterborne public transport. Stockholm, with approximately 6.2 million public transport boat journeys in 2022, is at the forefront of this movement. Gustav Hemming, Vice President of the Regional Executive Board in Stockholm, emphasizes the significance of expanding water-based public transport to enhance overall transit attractiveness.
While hydrofoil technology has a century-long history, recent advancements, including lightweight carbon fiber materials, efficient electric motors, and rising traditional fuel costs, contribute to its resurgence in public transport. Globally, other hydrofoil electric passenger ferries are under development, showcasing the industry’s readiness for change. Robin Cook from the Swedish Transport Agency emphasizes the importance of public infrastructure keeping pace with these innovations to encourage a sustainable shift in maritime transportation.
