Great group of guys in the customs and port office. .we were met at the quay and helped moor up. Then everything was explained to us . Had to go to only 3 offices and only a crew list had to be written to go along with our normal paperwork. Cash only remember. Can be got out of hole in wall across the road. New marina still not up and running due to paperwork. Dubrovnic marina very nice but a bit expensive for this time of year. Bus into old town at front of marina..good previsioning 10 minuites by bus. Just after big bridge by custom pontoon.

If you are heading to old town Dubrovnik and want to spend the night out at anchor in the harbor just out of the old walls, you will be asked for a 4Euros per meter fee by the Port Authority dinghy coming to collect the fee in the morning.

Also be aware that the Island of Lokrum, right in front of the old town, is a UNESCO site and unfriendly rangers will not allow you on the island before 0915 am. Besides that also note that if you are using the Imray Pilot Book by Trevor and Dyna Thompson you will be misled: the book states that u can anchor with a line ashore in Uvala Port, but this is false as a ranger will come by and force you to release the line.
Actually anywhere on Lokrum lines ashore are not allowed.
