In the afternoon we reached the bay of Bosa Marina and anchored there. It is a port for town Bosa, that is situated 2 miles up the river. It was quite windy, but warm, and we went for a swim in crystal turquoise water. Captain prepared the dinghy and the outboard and made a test drive. We last used outboard last August. Luckily everything was working well. We wanted to sail to the town next day with the dinghy.
After the expedition we were pretty tired and were just resting on the boat and swam a lot for the rest of the day. It was a really hot day, with almost no wind, not like the day before. We didn't even need any food, since we had such a big lunch. Since it was Friday, there were couple of parties going on on the beach, but not for too long. Everything went quiet shortly after midnight and we thought night would be calm. But no, at around 3 in the morning waves started rolling into the bay from SW, pounding on our boat and rolling it violently. None of us could sleep. We would gladly re-anchor, but we didn't know where to go. Luckily the worst didn't last long and towards the morning we were able to go back to sleep.
Next morning there were still some waves and the anchorage a bit rolly, so we sailed off already after the coffee. We were trying to figure out where the waves came from, but there was no wind anywhere near this side of Sardinia. Needless to say, none of the weather forecasts mentioned it either. Our next destination was Alghero, but we were mostly interested to find a good calm anchorage for the night and get some sleep.
