Rumors on the subject? what you mean?
I crossed the bay late September. My Wife wanted to visit Capri and called the marina to see if out of season the prices were reasonable. Well, they were not, for a 41ft boat 140€.
We stayed on anchor
at Baia on the North end of the gulf, in what was once one of the most luxurious place of the Roman empire. Well, what a waste, a beautiful natural site spoiled by bad architecture not controlled planning...a mess. We stayed on anchor
near a half sunken old big trawler. We where the only cruising boat on anchor
(several smaller boats were more near shore on permanent moorings).
I cruised the South of Italy and most of the time was the only boat on the anchorage, it seems that Italians prefer marinas.
From there I sailed to the Island of Ponza. A nice place with good anchorages and this time there was plenty of sailboats there. I guess that was because it was weekend and the place is at only a day sailing from Rome.
