Frequently Asked Questions

The Candela Seven​

All other electrical boats one the market have planing hulls which are draggy and therefore unsuited to electrification.
A 7,7m long planing recreational boat consumes 12-18 times more fuel than a family car. At the same time, one kilo of the best lithium-ion batteries contains just a few percent of the energy that can be extracted from a kilo of gasoline. Because of this, planing electrical boats are doomed to either short range or low speed. Even putting a battery pack of a 100 kWh or more in a planing boat will only result in 20-30 nautical miles of range at 20 knots (even if some boat makers unrealistically claim higher range). The only way of solving this energy equation is to use hydrofoils.

Better than anything else you’ve driven. Candela Seven’s seakeeping capabilities are second to none. Instead of pounding the waves, we fly over them. There’s no slamming, no heaving or rolling. Waves up to 1,2 meter just pass under the hull.
In really rough conditions, Candela Seven is like any other boat. You just reduce speed. However, the foils now act like a keel and give extra stability. See more on our YouTube channel.

Candela is a foiling boat. The foils lift the boat out of the water and reduce energy consumption by 80 percent compared to a normal, gas powered boat of the same size.

Serial production has already started at our factory outside Stockholm, Sweden. If you order now, we’ll deliver your boat within six to eight months due to high demand.

The Seven is 95 percent cheaper to drive than a gas-powered boat! A full charge costs 5-7 €. A comparable fossil fuel bowrider would use fuel for 200 €.

Nearly none. The foils cut through the surface without producing any swell, so sensitive marine habitats, moored boats and docks are spared from wake impact.

We use an advanced control system that makes the naturally unstable boat stable as a rock in just about any condition. Two ultrasonic sensors in the bow measure wave height. Height, roll and pitch are judged by sensors. These sensors adjust the foils 100 times per second, keeping the boat stable.

We exclusively use carbon fiber.

Going electric means no complicated engine, less breakdowns and less maintenance. We recommend one scheduled service appointment per year. Also, in cold climates, winterization should be done.

Candela is made in Stockholm, right in the eastern Swedish archipelago. Assembly is done in our own factory on the island of Lidingö, Stockholm, where we also make the carbon fiber deck. The hull and deck are made 100% in-house.

Yes, the foils are fully retractable by the push of a button. In shallow water mode, draft is 0,7 meters. Candela Seven can be launched and stored on a custom float-on trailer.

The foils are made from carbon fiber and are extremely strong, so hitting smaller debris will have little to no effect. Hitting a bigger object – a log or rock for example - will result in the foil breaking off at a designed point. Thus, the boat’s hull is spared from damage and buoyancy guaranteed.

We offer the Candela Seven in white as standard, with 4 signature colors available as a paid options. A fully customized color is also available upon request.

Yes, we offer the boat without the teak-decking, although we do recommend going for teak. We have looked on alternative foam based team imitations. Let's discuss with our production department.


Real-world and validated range is 50 nautical miles in 20 knots. This means you can cruise for more than two hours without noise, emissions or wake.

Top speed is 30 knots, with a range of 32 nautical miles.


Battery: 40 kWh lithium ion NMC battery pack (from BMWi3).
Motor: 70 kW for take off, 16 kW in 23 knots, 37 kW full speed.

Driver + 700 kg.


Hydrofoiling allows for much smaller batteries than non-foiling boats require. Therefore, our boats can charge pretty much anywhere. We utilize 230V/16A 1-phase or 110V34A 1-phase, We also offer 3-phase charging.

Charging a Candela is much faster than other boats, when taking into account nautical miles per hour spent charging. A full charge takes approximately 12 hours on 3.5 kW of power. With a 3-phase connection, the charging time is brought to 4 hours, on a relatively common 11 kW connection. Many other electric boats usually require 12h+ on a 11 kW connection.

About Hydrofoiling

Good question! While there are other hydrofoil boats around, they typically have surface piercing foils that are less effective than the fully submerged hydrofoils of Candela Seven. Our foils produce so little drag so that we can drive farther than the competition: For 2.5 hours in 20 knots, or 50 nautical miles. That’s an absolute world record for electric boats.

Hydrofoils are basically wings under the water. Under the surface, the Candela Seven works pretty much like an airplane. The main wing is mounted on struts under the hull and a smaller wing is mounted in the stern where the motor is located. At 16 knots, these wings produce so much lift that the boat flies above the water, thus reducing drag from the hull to zero.

About Candela

Deliveries began in Summer 2019, and by November 2020 we’ve delivered 18 boats to customers all over the world.

Candela has received funding from several investors, one of whom, Chris Anderson, is the Curator of, the company behind the concept of “Ideas worth spreading” and the massively popular online video series TED-Talks.

When creating something completely new it is important with good control of quality and communication, meaning we will keep building our boats in Stockholm and make sure to deliver exceptional boats.
