We living in Austria and think in retirement to go every summertime to Skandinavia and living on the boat (31 AC) in a harbour for few months. In winter the boat shoud stay there, waiting for us in next summer.
Is this possible, allowed and legal?
If yes, which harbour you can recommend for this. Preferred a small comftortable town, like mullerup ;-)

Hi!

I´m sure there is plenty of options but I can only can speak for Sweden/Ängelholm and the harbour in Skälderviken. https://maps.app.goo.gl/WXSqNPPYExfodknEA
There are some people that are living on their boats in the water all year around but I recommend to put the boat on land for the winter.
It´s possible, allowed and legal to do it. (not sure if it is allowed to have a permanent adress)
You will get access to showers and toilets all year around.

From Skälderviken you can make trips to Denmark, Helsingör, Gillileje (https://maps.app.goo.gl/1Pqtad986oirbQxy6) and other nice places in Sweden like Torekov, Båstad, Halmstad and so on.

Hopfully you will get more suggestions.

Sounds great, thank you! Sweden will be a fixpoint in jumping through the islands in the Schären.
