From concept to implementation


We had the idea of a high-power marine electric propulsion system. We believed that in a few years there would be a need for this type of product in the recreational market. The cost of large power storage systems was high. But at the same time, the cost of the propulsion systems was more affordable for really luxury yachts. It was at this point that we started looking at shipyards as potential partners to collaborate and develop boats that would carve out a niche in the market.


It was accepted to use a 2 x 250kW continuous power plant. With this available power, we would create the final design of the 60-foot catamaran. At that point, we realized that there was a need for a powerful DC charging system for boats with massive battery packs, far superior to those available in the automotive market. We began assembling a team and looking for a shipyard where we could bring our demonstration model to life. It was a challenge because we wanted the ultimate design with carbon fiber in all structural components and in as many places as possible.


After two years of developing the 60' cat, we have found a good solution for higher power. Visedo motors were able to provide 400kW continuous power. The system needed 800kW in total. With this opportunity we decided to have a look at the concept of power boat. We ended up with 57’ monohull with 2 x 400kW motors and a diesel-based variable RPM range extender that could provide a steady 390kW of power during the extensive work. With this, we reached ~30kn just on batteries and ~15kn of cursing speed on range extender only.


We decided that the building process would start relatively quickly. After searching for a partner for a long time, we decided to start our cooperation with Latitude Yachts based in Riga. It was not easy to find a shipyard that could handle such a complicated and challenging project. From the propulsion point of view, we had a system that suits super yachts sized 150’. At the same time, as we were aiming for the highest quality, normal shipyards in our boat size range were far away from super yacht finishing quality. This is how we ended in Latvia, and we cooperated well.


The boat exterior and all machinery was done. Due to COVID, the first sea trials were delayed. We were doing tests of the entire system assembled in our lab to ensure that all worked fine and that software development was going in the right direction. We tested each of our hardware to its maximum operational loads. We gained knowledge on what can happen in many different safety situations. In the end, we had made 6 months of dry tests of our system (with assembled hardware). Once we reached the moment when nothing else was possible on the dry test, we installed all components on a boat in the shipyard.
