I have had a go at this, the inventor lives about an hour north and sometimes comes down to our lakes. It took us about three goes to launch off a jetty. Pretty intuitive once you are foiling. You can go pretty fast, it has an e-bike motor. Trying to lean it over like a bike on a berm does not work. Water-starting is tricky. I was impressed with how they kept the electrics water-tight.
this is the logical next step for the cycling/golf turn kitesurfer crew
