I had a feeling that Candela’s hydrofoiling, all-electric powerboat was going to be a game-changer when my first story about the Stockholm, Sweden-based technology company began in August 2021 with this:
“You could say that the growing team of hyper-savvy engineers, software developers, yacht designers and boat builders at Candela have designed and built an all-electric powered boat similar to what Elon Musk has been doing with Tesla cars since Gustav Hasselskog founded the company in Stockholm, Sweden in 2014.
But that wouldn’t be quite right. In fact, what they did – create an electric-powered, zero-emissions speedboat capable of traveling up to 50 nautical miles at 22 knots between charges – was much more difficult than what Elon Musk has done, simply because boats are much have more drag to overcome than cars.
In fact, the car reference is perfect. However, Candela has just announced a partnership with a completely different manufacturer of all-electric cars: Polestar. And the result of their collaboration is Candela’s longest-range electric boat to date.
The Candela C-8 ‘powered by Polestar’ uses the same 69 kWh battery pack and DC charging technology as the Polestar 2 cars. This gives the boat an expected range of up to 57 nautical miles (65 frame miles) at a cruising speed of 22 knots (25 mph) – well beyond what Candela could achieve in 2021 – on a single charge!
In fact, the range is two to three times greater than what non-foil electric speedboats can achieve at high speed and compares favorably with traditional fossil fuel powered boats.
The secret to the long range lies in Candela’s highly efficient patented technology. By flying above the waves on computer-controlled underwater hydrofoils, the C-8 can fly 80% fewer energy than conventional high-speed boats. Meanwhile, the highly efficient Candela C-POD engine can produce 75 kW/100 hp for takeoff. And once up on its wings, the C-8 flies efficiently, drawing only about 23kW/30hp from its Polestar battery pack.
The partnership with Polestar also enables fast DC charging, opening up new routes and future-proofing the boat.
“With access to fast DC chargers, now popping up in marinas around the world, you can take completely new routes with the Candela C-8. You can go from Sweden to Finland in one day, or the entire French Riviera in a few hours. For just a few euros in electricity,” says Gustav Hasselskog.
“Sharing battery and vehicle technology know-how with Candela will help achieve our shared goal of moving towards a future where all modes of transportation are sustainable,” said Thomas Ingenlath, CEO Polestar.
As a parent and person who is genuinely committed to preserving our planet for future generations to enjoy, I am pleased to report on the progress Candela and Polestar are making to help protect the health of our oceans through the application of advanced technology on these very difficult problems.
Can I make another prediction?
I predict that global adoption of this waterborne technology is only a matter of time, for one simple reason: The C-8 (and whatever Gustav and his merry band of smart engineers come up with in the future) are building some of the coolest boats in the world that also happen to be among the greenest.
And that’s not easy! Stay tuned for more.
