"Candela's hydrofoil electric speedboats set new world record with international voyage."
International because they went from Sweden to Finland. And back. 150 nautical miles == 172 regular miles == 278 km. From Stockholm, Sweden, to Mariehamn, "the capital and largest town of the Åland Islands, an autonomous region of Finland", but with a charging stop in Kapellskär, Sweden. The part from Kapellskär to Mariehamn was 1 hour 20 minutes. That stretch is 36 nautical miles one way.
"The voyage marked the first time an electric boat has ever crossed the Baltic Sea, and it did so in style, flying roughly a meter above the waves on a hydrofoil boat. The Candela C-8 makes use of computer-controlled hydrofoils that lift the boat out of the water, leaving just 1% of the boat in the heavy resistance water. By soaring through the air, the Candela C-8 uses just 20% of the energy needed by other boats."
