Candela’s C-8 electric hydrofoil outboard can go at 35 mph and last over 56 miles before recharging

0

Just months after showcasing the world’s first AI-powered electric hydrofoil, Swedish boatbuilder Candela unveiled its $ 339,000 suite, which can travel over 56 miles before needing to be recharged, the longest range of any electric boat ever produced.

Released as a hand-crafted limited edition in July 2021, the Candela C-7 has proven to be such a popular product that demand has exceeded supply, Eletrek reported, and the company envisioned an easier-to-produce successor, the C-8.

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

This leaves room for a cockpit for eight passengers, a large sundeck, a spacious cabin with a four-person sofa, beds for two adults and two children, a freshwater shower and marine toilets.

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

Candela has unveiled her new all-electric hydrofoil outboard, the C-8, which she says can exceed the C-7’s nautical limit of 50, already 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 demonstrated that our hydrofoil technology not only allows a long range on electricity, but also offers a better experience than conventional boats… you get a smoother, more enjoyable ride,” said said Gustav Hasselskog, CEO of Candela. in a report.

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

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

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

The 27.8-foot boat features a spacious cabin with a sofa for four, beds for two adults and two children, as well as a freshwater shower and marine toilet.

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

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

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

Candela’s communications director, Mikael Mahlberg, told Electrek the goal is to get high-end combustion-powered boats out of the water.

“I suspect he will do it with a wide margin, hopefully this is an iPhone moment for boats – something that will radically change the way we perceive how boats should be and look like. Not loud, expensive to drive, shaking and slamming and poisoning the very nature you come to enjoy – but completely silent, intuitive to use, fun to drive but still relaxing for passengers, nature friendly, maintenance free, very good market to use and scalable … ‘

A carbon fiber hull reduces the energy required to bring the C-8 up to a speed of 16 knots (about 18 mph), when the hydrofoils spread out and the craft rises above the water , reaching a top speed of 30 knots (35 mph).

As with the C-7, the C-8 has an autopilot function linked to an AI system that adapts to real-time changes in the waves and keeps the boat on a preset course while the skipper can relax.

Raising on the foils reduces water friction by up to 80%, Candela said.

When the foiling is activated, the C-8 can achieve a cruising range of over 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.

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

The Sarvo 37, from the Danish company Sarvo Marine, can go over 80 mph and reach 100 nautical miles (approximately 110 miles).

It was slated to launch in July 2021 but is still under development, according to to the new atlas.

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

The front and rear foils can retract for easy storage or use in shallow water.

As with the C-7, the C-8 has an autopilot function linked to an AI system developed by Candela that adapts to real-time changes 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 plans to begin production in January 2022.

Candela is also working in tandem with local authorities in Stockholm to develop the world’s fastest all-electric ferry, the Candela P-30, an airboat capable of carrying 30 passengers at speeds of up to 37 miles per hour.
