Dubrovnik is a beautiful place and beautiful people. I tied up on that same pontoon in about the same spot a couple of years ago. Really friendly staff and people. I dunno who the goose with the knife is or why he was an ******* but I guess there's more to the story..there usually is..
We only stayed an hour or so, long enough for a meal and to ask the marina
price. We ended up going upriver to the less expensive and nicer marina (who were also typically friendly )
yes its a Polish flag on the yacht
