Presentation of a new electric boat
Today, the electric boatmaker Candela unveiled the first product emerging from the battery collaboration with premium electric car brand Polestar announced in August 2022: Candela C-8 ‘powered by Polestar’, the longest-range electric boat to date.
The Candela C-8 will use the same 69 kWh battery pack and DC charging technology as the Polestar 2 and has an expected range of up to 57 nautical miles (65 US miles) on one charge at a cruising speed of 22 knots (25 mph).
The range is two to three times longer than what conventional electric speedboats can achieve at high speed and compares favorably with how internal combustion engine powerboats are used.
The secret to the long range lies in Candela’s hydrofoil technology. Flying above the waves on computer-guided underwater wings that greatly reduce water friction, the C-8 uses 80% less energy than conventional boats at high speed. Its highly efficient pod motor, Candela C-POD, outputs 75 kW/100hp for takeoff.
Once foilborne, the C-8 flies efficiently, drawing only around 23 kW/30hp continuously from its Polestar battery pack – whereas a similar-sized conventional boat would use around 120 kW/160hp.
The supply of battery and charging systems to a third party, a first for Polestar as an EV manufacturer, marks the start of a broader intended partnership between Polestar and Candela.
