wing that can be put up the ship. measuring the flow that is actually clear is really difficult. this vessel here is seven metres long, mainly made out of glass fibre. the full—scale ship will be around 200 metres long, roughly 80 metres in height and the mission is this would sail at the end of 2025 or early 2026. what makes wind really interesting, it's of course free of charge, we know there will be wind in the future. up there, you will have very little disturbance. it has been a lot of learnings. we have roughly around 150 sensors measuring up to 200 data points every ten seconds, pressure, wind speed and also the direction of the ship. when you change the angle of attack, that will be a big difference in how
