We had a really interesting discussion with my Dad about the 'Sweden boats'. These are ferries that sail between Helsinki and Stockholm, every day, overnight.
Ever since I was a child these boats represented something new and exciting. My Dad told me that the cruises started after the war, and the first ships were all Swedish (e.g. Svea-line). Currently the two big companies are Silja-Line and Viking Line.
The epic dinner buffets on the 'Sweden boats' have served luxury and abundance to ordinary people from their inception. Many Finns tasted their first shrimp or fresh pineapple on the boats!
