Lipari is beatiful but I don't think you can enter the small
fish harbour with yr 57..We did it with our 44 cat but in December and with a lot of arguments with fishermen's
boats..
Don't miss Catania on the west end of
Sicily. Out of the marina walk along the antique walls to yr left and at the very end there is a small
fish restaurant at the entrance of fish market. That's the best in the
Med at very reasonable prices run by a
family..
If the
wind is OK, the north of Crete (Xania, Ritminos and Agio Nicholas) is beatiful ,in this season and the
marinas almost free.. (Skip Iraklio, the worst place in the Med)
You can then make various islands on yr way to Marmaris, Karpatos, Halki and Rhodes if you like.
