yes I live near Adriatic
In fact Croatia is really beautiful from the nautical point of view I find it better than Italy
Which part of Croatia you are going to?
You can't miss Plitvice in the internal part. As for the sea, there are a lot of nice island; I know well the Norther part until Hvar, never been in the south part yet.
Chartereing is really well developped there you have hundred of choices between staying in marina, on buoys or in bay using your anchor
The northern and middle part is made by small islands you can wander within, then going down islands become larger.
Many beautiful towns too, mostly due to Venice past domination.
Feel free to contact me for any further infor
