Candela C-8 Electric Boat: Using Hydrofoils and Automotive Batteries for Efficient Marine Transport

The Swedish company Candela has developed the C-8, an electric boat that utilizes computer-controlled hydrofoils to lift the hull above the water. This design significantly reduces friction, allowing the vessel to operate more efficiently than traditional electric boats. Powered by a 69 kWh Polestar battery, the C-8 can travel approximately 105 kilometers at 22 knots. This approach addresses the energy density challenges of marine electrification by reducing the power required to move through water.

Using a 69 kWh car battery for a boat is a clever way to keep costs down, but I wonder about the cycle life in a saltwater environment. Does the hydrofoil system actually lower the discharge rate enough to prevent rapid degradation?

The maintenance on those foils is what worries me. Carbon fiber is great for weight, but salt crust and biofouling on the foil surfaces will kill that efficiency gain quickly if they require constant scrubbing.

The tech is cool, but the real shift happens when urban water transport regulations mandate zero emissions. Without specific subsidies for electric ferries or leisure craft, this stays a luxury toy rather than a decarbonization tool.

Basically a flying boat powered by a Polestar battery. It solves the drag problem that usually makes electric boats impractical for anything beyond a pond. Worth a look for the efficiency gains.
