Merci Alain, I appreciate it!
60 miles from the coast is impressive, I didn’t know Edel4 can go out that far. I have the Keel+Centerboard version. I don’t think I’ll ever dare to go out that far with it though.
I just don’t want authorities to categorize it to D, I plan to take it to near coastal areas around Croatia (later, when I’m more experienced).
The boat has Polish papers and the lady in the office asked me about the category. I guess I’ll tell her B and maybe they will agree on a C 
Merci encore,
Peter
