First Electric Boat Successfully Crosses the Baltic Sea

A group of Swedes set a world record by driving a hydrofoiling Candela C-8 between Stockholm and the Finnish autonomous region of Åland, marking the first time an electric boat has crossed the Baltic Sea and made the journey between the two countries. They even returned the same day – at 95% lower costs than a fossil-fuel-powered boat.

"The aim was to demonstrate that zero-emission sea travel is not only possible today, but that foiling electric ships and boats are so much cheaper to operate than fossil-fueled vessels," said Gustav Hasselskog, CEO and founder of Candela.

The Stockholm-based tech company has developed the world’s first electric hydrofoil boats and ships, vessels that fly above the water with an 80% reduction in energy consumption compared to traditional ships, providing both long range and high speed on battery power.

The record trip was made last Thursday in the latest version of the leisure boat Candela C-8, equipped with a Polestar battery, starting at 6 a.m. from Stockholm’s Frihamn. After a charging stop in Kapellskär, they reached Mariehamn, the capital and largest town of the Åland Islands, an autonomous region of Finland, at lunchtime, making it the first electric boat to cross the Baltic Sea between Sweden and Finland. In the harbor, the electric boat pioneers were greeted by a delegation headed by Åland's Premier, Kristin Sjögren.

“The disadvantage of electric boats has been their short range, due to traditional boat hulls consuming so much energy. With our hydrofoil technology, we combine high speed and range, but you get so many other benefits. Flying over the Åland Sea in total silence and without slamming was absolutely magical,” said Gustav Hasselskog.

The trip was made mostly with the existing charging infrastructure, and in partnership with Kempower, a charging solutions provider. In Kapellskär, the Candela charged with a Kempower Movable Charger, a 40-kW wheeled charger connected to the existing power grid at the harbor. In Finland’s Mariehamn, the boat was plugged into the marina’s three-phase outlet. In the evening at 6 p.m., the electric boat pioneers flew back toward Sweden. After a top up in, Kapellskär, the C-8 returned in dense fog to the starting point, Stockholm's Frihamn, at 11.30 p.m.

“Kempower is proud to contribute to the electrification of boating and help create greener waterways. Electric boats combined with hydrofoiling offer the best possible efficiency. Kempower's DC fast charging solutions are ideal for electric boating, and our Kempower Movable Charger is a plug-and-play solution that integrates seamlessly with the electrical grids already available in many marinas,” says Antti Vuola, Director, Market Segments, Kempower.

“We actually had range anxiety, but not for the Candela. The irony is that the photographer’s gasoline-powered chase boat had to refuel six times during the trip, while we only charged three times,” said Gustav Hasselskog.

Candela's hydrofoil technology enables massive cost reductions for sea transport, which was proven when the electric costs were summed up. The gasoline-powered chase boat of similar size that accompanied the trip had to refuel for 750€ during the 150 nautical miles – while the Candela C-8 consumed 213 kWh of electricity, at a cost of about 40-50€.

“We’re talking about 95% lower operating costs. This is a revolution that makes waterborne transöport competitive with land transport in terms of costs, which we will now demonstrate in public transport in Stockholm,” said Gustav Hasselskog.

This fall, Candela P-12, the company’s new 30-passenger hydrofoil ferry, will begin operating the Ekerö-Stockholm City Hall route, where it is expected to halve travel times thanks to not producing damaging wakes, allowing it permission to travel quickly in the inner city.

Candela has recently announced a deal to electrify the water transport network in Saudi Arabia’s giant NEOM project, as well as ferries sold to cities ranging from Berlin to New Zealand.

"We can easily electrify coastal public transport at very low costs, not just in Sweden but across the world. It just requires political will to make the switch,” concludes Gustav Hasselskog.

Stockholm-based Candela Technology AB is the world leader in hydrofoiling electric vessels. The company was founded in 2014 by engineer and business leader Gustav Hasselskog with the mission to accelerate the world's transition to fossil fuel-free lakes and oceans by developing electric vessels that outperform those powered by fossil fuels.

Candela's watercraft have wings (hydrofoils) that lift the hull above the water and reduce friction, using 80% less energy than conventional ships at high speed. This technology allows for long-range water travel solely on battery power, a first in the industry. Candela's hydrofoils also enable operators to transition to sustainable fleets by providing up to 50% lower operational costs.

At the heart of Candela's hydrofoil tech stack is the Flight controller, which automatically stabilizes the vessel during flight by regulating the foils, using sensors that gauge wave height and wind speed, among other factors. Even in rough weather, passengers experience 90% less g-forces than they would on a traditional boat. All Candela vessels are fully connected and receive over-the-air updates.

After five years of research and development, Candela began producing the world's first electric hydrofoil leisure boat in 2019, the Candela C-7 open "roadster of the seas". This was followed in 2022 by the high-volume market Candela C-8, which was delivered to the first customers in spring 2023. Over 150 C-8 units have been sold to date, and the vessel has been lauded as a "game changer" by Motorboat and Yachting magazine, winning numerous awards including the 2022 European Powerboat of the Year award for its superior seakeeping, long range, and high speed.

In 2023, Candela launched its first commercial vessel, the Candela P-12 Shuttle ferry. It is the fastest and longest-range electric ship ever built, with a top speed of 30 knots and a range of 40 nautical miles at 25 knots. It is also the most energy-efficient fast ship ever made in its size class. Substantial operational cost savings are expected. The first unit enters service in Stockholm's public transport system in 2024.

Candela is a technology company with headquarters in Stockholm, Sweden, employing over 200 engineers, technicians, and production staff. The company develops the entire tech stack, from the C-POD motor to the control system and carbon fiber hulls, in-house. Candela's two wholly-owned factories in Stockholm, Sweden, produce the Candela C-8 and P-12 vessels. The company also has leisure boat resellers in 12 countries and wholly-owned sales offices in San Francisco, USA, and Cannes, France.
