I had first signs of sea-sickness (or "sea-travel discomfort" how the pharmacies name it). Rested a bit. But then I had enough energy to drive the ship through the night to the Nord-Ostsee-Kanal. Traffic on the Ocean is kinda different from the Highways ... cause there are huge, massive differences of ship sizes and speeds !!! You have to look farther and react very soon to avoid stressy situations.
