Plume at the Peak: How we broke the 17 kg barrier
A look back at 3 years of R&D in the French Alps to engineer the lightest and most hydrodynamic carbon e-foil.
When an e-foil weighs 30 to 35 kg, getting to the water becomes a logistical chore. From our first sketches at Lake Bourget, our target was a total ready-to-ride weight under 17 kg.
By combining a high-modulus Toray® carbon monobloc mast, passive cooling without fragile water pumps, and our folding propeller blades, we reduced hydrodynamic drag by over 28% at cruising speed.
