Technology: Candela – Swedish foiling boats get boost

Candela C7

Dec 23, 2021

C-7’s computer controlled Foil System offers an almost completely silent driving experience and a very smooth ride, even in choppy conditions.

Another innovative alternative boatbuilder is in the news. A venture capital arm is taking a stake in Candela Speed Boat AB, a Swedish startup making electric boats that rely on hydrofoil technology.

EQT Ventures led a 24 million-euro ($27 million) funding round that will enable Candela to scale up the production of leisure boats and start building battery-powered passenger ships for public transport.

As boatmakers seek ways to electrify crafts, Candela is betting on hydrofoil as a means to compete with combustion-engine boats. Its vessels are equipped with underwater wings that allow them to glide above the water surface–a method which, according to the company, enables more efficient energy use and a smaller battery.

“We’ve shown that our hydrofoil tech is the key to make electric boats commercially viable,” Candela’s chief executive officer Gustav Hasselskog said in a statement.

C7 Lineup

Since 2019, Candela has led electric boat sales in Europe with the foiling C-7 sportsboat. That model hit speeds of 55 km per hour when its foils lift it out of the water. Its manufacturers say it travels further and smoother than other electric boats.

The foils reduce water friction – and the effect of waves slamming into the boat – cutting energy consumption by 80% compared to normal diesel-powered boats and extending the craft’s range to 90 km (56 miles). The price tag is in the range of 250,000 euros. Candela C-8, a day cruiser that the company more recently has reportedly close to 100 orders for, just three months after launch.

Here’s a look at how the Candela Seven runs

Neptunus 650F Review

Neptunus 650F 400

By Andy Adams

Over the years Canadian Yachting has had the pleasure of doing several boat review articles on new Neptunus models and we are familiar with the qualities that Neptunus is famous for. They have all been exceptional yachts, but this is the one I would most want to own myself. It’s a personal choice and a matter of taste as to whether you would prefer to have a sedan express model or a flybridge but in my opinion, the flybridge layout offers some wonderful attributes.

We met with Neptunus Managing Director Jan Willem De Jong this past fall to take the new Neptunus 650F out in Lake Ontario.

The Other Virgin Islands

Sunset off St John

By Mark Stevens

I was first seduced by the United States Virgin Islands during a ferry ride from St. Thomas to Tortola to begin one of our earliest British Virgin Islands charters nearly twenty years ago.

A perfect sunset off St. John with St. Thomas views for backdrop.

Clearing Pillsbury Sound, surrounded by voluptuous emerald mountains as the ferry sliced through royal blue waters, I was struck by the unspoiled ambiance of St. John, the island gliding past our starboard beam and the irresistible charm of a village called Cruz Bay visible from our quarter stern.
