C-7 Electric Speedboats Arrive in New York

The Swedish-made Candela C-7 electric speedboat mimics airplanes to fly above the water, reducing friction and enabling long electric range at sea. The first batch of C-7s have arrived in New York.

Taking inspiration from fighter jets and drones, the six-passenger day cruiser flies above the waves at a speed of 30 kt., using very little power from its 40-kWh battery. 

The secret behind its efficiency is a decade-old invention, the hydrofoil, coupled to modern computers, software and sensors.

At speeds above 14 kt., two underwater wings provide enough lift to raise the hull above the water, reducing water friction by 80%.

This allows for a range of 50 nautical miles at 22 kt., which is three times longer than any other fast electric boat on the market, Candela said.
