The hull of the Candela C-8 was intended to be a sleek 'minimalistic Nordic design,' aiming for efficiency. The hydrofoils reduce water friction by allowing the craft to fly above the waves, while the hull’s sleek, rounded bow and tapered stern minimise air resistance. Advanced computer modeling and has been extensively used to simulate drag, with details such as flush fold-down cleats and a carefully angled windscreen enhancing both aesthetics and aerodynamic efficiency.

“We’re honoured to see our efforts to redefine the boating experience being recognised by the German Design Council” said Niklas Nordin, Head of Products at Candela. “The C-8 is a testament to functional design, its minimalist aesthetics stemming from the need for lightness and aerodynamics. The C-8’s efficiency is the key to making a truly sustainable boat. Just like gliders with their smooth, graceful lines, it is designed to be as 'slippery' as possible.”

The design, combined with the hydrofoil system, a lightweight carbon fibre composite build, and an energy-dense Polestar battery, has been designed to make the Candela C-8 one of the most energy-efficient powerboats in the world – with the longest electric range. By flying above the water, the Candela C-8 uses 80 percent less energy than a conventional powerboat, resulting in a long range on battery power. With a top speed of 27 knots and the ability to cover over 50 nautical miles at 22 knots, the C-8 is the first electric boat to rival fossil fuel competitors in terms of performance.

Once foilborne, the C-8 ‘takes off’ at 16 knots, with a silent and smooth ride for passengers. In the background, the boat's Flight controller works with the help of sensors that detect the waves and adjust the hydrofoil's angle of attack 100 times per second so that passengers do not notice the motion of the sea, aiming to eradicate the risk of seasickness.

Among other standout features is the motor, Candela's own C-POD. This direct-drive electric motor, fully submerged, aims to achieve a silent ride with no transmission losses. It is also designed to last 3000 hours without maintenance - or ten times longer than a gasoline outboard.

“When designing the C-8, we set out to redesign the boating experience from the ground up” added Mr Nordin. “What if we could eliminate all the negative aspects associated with powerboats while retaining the positives? With the C-8, you get the speed and range for your trips, but without the pollution, noise, ridiculously high fuel bills, bumpy ride, and high maintenance costs of ICE motors. To me, the most mind-blowing feature is the silence. Flying above the waves at 20 knots and talking to the passengers in the aft sofa in a normal tone of voice? You could never do that in a conventional boat.”

Candela recently hit a milestone, by delivering the 40th produced Candela C-8 from its factory in Stockholm, Sweden.
