Go Underwater. Skip the Fins.

An eFoil gets you flying above the water. The Subnado gets you moving beneath it, no fins, no exhausting kicking, just a compact motor doing the work while a finger ring controller does the steering. Waydoo built it to travel: pack it in a carry on, charge it over USB-C in about an hour, and take it wherever there's water worth exploring, a pool, open water behind your paddleboard, or a dive down to 60 meters.

eFoil Republic carries the line in three builds, Lite, Standard, and the dual engine Plus for anyone who thinks one motor is a polite suggestion. Same idea across all three: strap in, point where you want to go, and let the scooter do the swimming.
