We had chosen the Linda Line fast cat for the crossing from Helsinki to Tallinn, as being quicker and cheaper than the big steamers. Its departure point from Helsinki was just a short walk from the Lilla Roberts hotel. After we had checked in we noticed that all crossings scheduled for later in the day (after ours, that is) were cancelled, but didn't think too much about it. But all was soon revealed - there were storms and rough seas forecast, which is not unusual, I gather.
We bounced around a bit, but nothing too much for inveterate sailors like us. We were, however, almost an hour late getting into Tallinn (the timetable allows 1h 40m), and there was no sign of the car that was supposed to meet us, but a quick phone call to our hotel (Vodafone roaming was fantastic throughout our trip), we caught a taxi and in no time at all we were checking in to the Three Sisters hotel.
By the way, the Linda Line terminus in Tallinn was originally built as the base for the Yachting events during the Moscow Olympics in 1980, Moscow of course not having open water, and Estonia at that time being effectively under Russian control. It was an ugly, desolate concrete structure!
