Amazingly unintended coastline. The number of secure bays over the entire "boot" can probably be counted on the fingers of one hand, so the marina budget
has to be considerable.
The people are very friendly, and the marine
services tend to be excellent in most places. Civittaveccia (sp?), a few hours North of Rome, has an amazing marina with just about everything from sailmakers to upholsterers to electricians...
Ostia is very nice too, and cheap
by Italian marina standards, which is useful because it's the jumping off point for the magnificence that is Rome.
Nettuno is just about the most southern marina where sailboats are still common. South of that masts are rare.
Naples deserves its reputation for being dirty, but its citizens are welcoming and genuine human beings. I loved Naples, and I missed it far more afterwards than the more touristy places.
Sorrento and the Amalfi coast are great if you want to sit in clifftop restaurants, but there's few facilities for a cruising sailboat
Salerno marina is overpriced and devoid of services. Theres little to see South of there until you get to...
Tropea!!! For me the best place on the Italian mainland! Postcard-perfect blue water
, nice little marina which doesn't break the bank, and even a little anchorage out the front... could easily spend more time there.
The Straits of Messina are an amazing experience.after that, its low-key until you get to Corfu.
