Based on existing functional principles (inventor: Ulo Gertsch) we developed a novel drive concept for a pedalo for the company Inventra. Vertical immersion and bucket drive blades reduce water splash to a minimum, improving performance. In addition to the design of the drive we could design different designs for a possible watercraft. The first functional prototype was successfully tested for water in October 2016. Implementation to series maturity and industrialization is expected to continue in 2019.
