As amateur surfers, Alex and Dmitri really struggled to get into the line-up practicing surfing in Huntington beach, famous for its swells.

Having an old shoulder injury, Alex realized that it would be a major obstacle for him, so he suggested coming up with some solution that can help people get into the lineup quicker. Dmitri supported the idea and suggested putting a motor inside a fin. The idea of an eFin that will give you that push to get to the lineup, to surf longer, and to catch more waves, was born.

Having an engineering degree, Alex got busy bringing this solution to life. He has created the first prototype and together with Dmitri, they began surfing non-stop and testing it. This is how the first electric fin was born.
