Hi Dockhead, welcome to our cruising grounds! Choose the Länsisatama (Western Harbour) for Your stay as it is better suited for bigger Yachts than the eastern one.
I'm afraid You cannot find tax-free diesel at the
marinas (Itäsatama and Länsisatama) as it is illegal to use in
boating purposes. Road side gas stations will sell red diesel as it is allowed for agricultural use. If I remember right You could find red diesel in
Sweden in Dalarö, some 40 to 50 miles to the south from Stockholm. It is a very small but beautiful marina.
Those Finnish fuel prices are in the mid range compared to Swedish,
Denmark and German fuel prices this summer. The highest
price I paid during our Around the
Baltic cruise this summer was in Sweden at 1,75 euros per litre.
Fair winds,
