My longtime friend Heidi called on 6th September and asked if I was interested to join her on the 7th for a day of boating going to the old naval fortress of Katanpää from Uusikaupunki where her boat was moored. I agreed and we set out from our house in Kustavi early in the morning by car. Arrived about an hour later and set to prepare Heidi's boat for the trip, it was already fueled so it wasn't much more than a bit of snacks and drinks.
