In July 2017 after a long night full of ideas and slipslop in Berlin Tuomo and I ended up with the plan to take the SWATH design to the max and modify the concept to just a deck above the surface carried by a three-tube underwater submarine platform. The center tube would later be the place for all the tech stuff creating the descending force, the two side tubes would be the ballast tanks creating the ascending force. Now it was time to get our hands on prototyping for a very first study.
