Hej då (hi) welcome to TF.
I visit every summer holiday in the Swedish waters, mainly Stockholm's archipelago, it's a fantastic island hopping adventure and very nice argipelagos to.
Europe's inland waterways are an interesting opportunity for boats this area and to see new places and things.
I myself have the same idea of going to the channels in the years to come. I went to CENVI training last winter and now all licenses are ok for the upcoming trip (ICMS) when it's time.
Do you have a boat place on Linköping Lake or on some were Coast?
