Candela’s C-8 electric hydrofoil speedboat can go 35mph and last over 90 miles before being charged

Just months after introducing the world’s first AI-powered electric hydrofoil, Swedish boat builder Candela has unveiled its $339,000 sequel, which can travel more than 90 miles before needing a recharge, the longest range of an electric boat. that has ever been produced.

Released as a handcrafted limited edition in July 2021, the Candela C-7 proved to be such a hot item that demand outstripped supply, Eletrek reported, and the company has come up with a successor that is easier to manufacture, the C-8.

That’s a steep $240,000 price hike for the C-7, but the new model uses less power and is much more spacious — about 31 inches longer than its predecessor.

That leaves room for an eight-passenger cockpit, a large sun bed, a spacious cabin with a four-person sofa, beds for two adults and two children, a freshwater shower and a maritime toilet.

Candela says the sticker price on the 27.8-foot C-8 is comparable to premium gas-powered motorboats in the 28- to 29-foot class.

Candela has unveiled its new all-electric hydrofoil speedboat, the C-8, which it claims can break the C-7’s 50 nautical limit, three times longer than other electric boats. It is intended for ‘volume production’ to compete with combustion engine boats

“With the C-7, we have shown that our hydrofoil technology not only enables long range on electricity, but also offers a better experience than conventional boats…you get a smoother, nicer ride,” said Candela CEO Gustav Hasselskog in a statement.

But the C-7, which debuted at the Venice Boat Show in June 2021, “was more like a hand-built sports car;” he added, “never intended for volume production.”

The C-8 is aimed at mass production, Hasselskog said, without sacrificing technology, comfort or efficiency.

It has an optional hardtop, a premium sound system and a 15.4-inch high-resolution touchscreen for navigation and controls.

The C-7 had a range of 50 nautical miles (57 miles) before the 40 kWh battery needed to be recharged, which Candela says is already three times the range of other electric boats on the market.

However, the C-8 goes beyond that limit, the company said, thanks to a larger 44 kWh battery pack, an improved version of the hydrofoiling system (which allows it to glide over the water), and an energy-efficient C-POD electric propulsion unit with a 55 kW motor at the heart.

The C-8's hydrofoil system helps reduce wake to just 2 inches, making it much less destructive and disruptive to marine life than conventional powerboats.  The films can be tucked away for storage or in shallow water

Candela communications manager Mikael Mahlberg told Electrek the goal is to knock premium combustion engine boats out of the water.

“I suspect it will do this by a wide margin, we hope it’s an iPhone moment for boats – something that will radically change how we see how boats should be and look. Not loud, expensive to run, shake and hit and poison the nature you have come to enjoy – but completely silent, intuitive to use, fun to drive but still relaxing for passengers, respectful of nature, maintenance free, very cheap in use and upgradable…’

A carbon fiber hull reduces the energy required to get the C-8 to a speed of 16 knots (about 29 mph) when the hydrofoils extend and the craft rises above the water, and a top speed of 30 knots (35 mph) reached. ).

As with the C-7, the C-8 has an Autopilot feature coupled with an AI system that adapts to real-time shifts in the waves and keeps the boat on a preset course while allowing the skipper to relax.

By rising on the foils, water friction is reduced by up to 80 percent, Candela said.

When foiling is enabled, the C-8 can achieve a cruising range of more than 50 nautical miles (58 miles), the company said, after which the boat’s 44 kWh battery can be recharged in about two hours with a three-phase charger.

FLOATING ON WATER: HOW DO HYDROFOILS WORK?

Hydrofoils are lifting surfaces – analogous to the wings of an airplane’s wing – that operate in the water.

As a hydrofoil gets faster, the foils lift the hull out of the water, reducing drag and allowing greater speeds.

Hydrofoils were first conceived by the Parisian engineer Emmanuel Denis Farcot in 1869.

The Sarvo 37, from the Danish company Sarvo Marine, is said to be able to reach more than 80 mph and reach 100 nautical miles (about 110 miles).

It was supposed to launch in July 2021, but is still under development, according to to New Atlas.

The C-8’s hydrofoil system also helps reduce wake to just 2 inches, making it much less destructive and disruptive to marine life than conventional powerboats.

Both the front and rear wings retract for easy storage or operation in shallow water.

As with the C-7, the C-8 has an Autopilot feature coupled with an AI system developed by Candela that adapts to real-time shifts in the waves and keeps the boat on a preset course while the skipper can relax.

Candela is now accepting reservations for the C-8 and expects to begin production in January 2022.

Candela is also working with local authorities in Stockholm to develop the world’s fastest all-electric ferry, the Candela P-30, a hydrofoil that can carry 30 passengers at speeds of up to 60 kilometers per hour.
