“We were on the way back to the Netherlands with our boat, a Jetten 50. As we were between Langeland and Kiel we encountered gusts of wind up to force 7 and waves 2 metres high, perpendicular to the boat. The ship turned out to be incredibly seaworthy. We surfed down the waves. Even in these tough circumstances, the rotor system we have on board reduced the sideways motion of the vessel down to zero.”
