Navier 27 Electric Foiling Boat Ever heard of Navier before? There's a good chance that you haven't because this is the name of a Californian start-up. The Navier 27 is their first splash and it's a bold initial offering. Firstly, it's an electric boat and secondly it's an electric foiling boat. While boats and even smaller ships have used foils before, such as hydrofoil craft in ferry and even naval applications and to a lesser extent with the Hull-Vane of Heesen 42-meter build "Alive", it is still not widespread across the industry.
