Your Baltic cruising guide is a great book, that I would like to contribute to.
I have two additions to my town lübeck:
The historic yachts are in the Holstenhafen, rather than the Hansahafen.
The one pontoon and the scant facilities in the Hansahafen have been replaced by the newly built „Newport Marina“. 45 berths. Finger berths can accommodate up to 17m yachts, and there is space for yachts up to 40m. And a nice restaurant.
This is a real destination and a great improvement.
