and open "osrodek marina" and "porcik jachtowy"
you will see that it is in English so no problems here
I was staying in the wooden house by the marina
You will see the habour master / passport control building on the other side of the river and it is up them who goes out to sea and who does not. With my SSR registration document, RYA certificate, safety equipment on board, and of course passport no problems. This is a good thing cos stops those who want to go out without any safety equipment and unsafe boats ect
But if one fitted a tube around ones bath tub stuck an outboard on the back and launched it from the beach then that is OK . can't think what fool would want to do such thing anyway
