An efoil is a surfboard with an electric propeller just above the wing of the hydrofoil. This powers the board to move through any water. The efoil is powered by a nearly silent electric motor and rechargeable battery. It’s controlled by a handheld wireless remote that syncs to the eFoil via Bluetooth.
The efoil rider doesn’t need to paddle for waves or pump with their legs to keep the board in motion.
