Dear next crew, you will find Sofia II docked here at this pier closest to the yellow service house and the clubhouse. I think it is 6th or 7th spot counted from the water harbor entrance away. Look at the attached picture below trying to give you enough clues. It's about 3km away from the train station, so grabbing a taxi could be good.
Ask for Karlskrona Segelsällskapets harbor on Dragsö.
