Electric Hydrofoil Watercraft

Abstract

The electric hydrofoil watercraft according to the invention has a thermally insulated mast, thermal insulation and vibration isolation are provided between the mast and the above-water platform by placing an insulating element between them. This increases the life of the hydrofoil and improves user experience.
