Ferry schedule for Sorrento - Positano - Amalfi Town

This is the line I used several times. they seemed good and squared away. Some of the links on their website did not work just now, but others did and I was able to find schedules and routes.

Thanks for the link - most of the links on that page are broken.

I am still having trouble figuring out how to read it.

I have read here that there are "slow ferries" and "fast ferries" We would like to go from Sorrento to Positano to Amalfi spending time in both Positano and Amalfi (with a possible trip up to Ravello). Then take a late ferry back all the way to Sorrento. Is this possible?

I'm making the same trip a week later. In searching for the ferry schedule, I came up with this link:

Click the link for line ferries. Part is in English, but not the schedule.
It contains this line "- servizio giornaliero ogni 30 minuti dalle 9.00 alle 17.00 dal Molo Pennello". I'm guessing that means ferries every 30 minutes every day 9:00am-5:00pm?

Anyone speak Italian who can confirm this is correct?

I speak Italian and you have the correct translation.

I was in Sorrento, Capri and Positano two weeks ago -- and I thought I figured out the on-line ferry schedules in advance. I discovered that the more reliable thing to do is to go to the port and check the posted schedules. Eg. I was told in Sorrento that the scheduled ferry from Positano was not operating for the next 7 days, but when I arrived in Positano (by bus) I found that there was a convenient ferry for my return which I took (and was very glad I did.)

Does anybody know if the ferry service runs the whole year ? if not, when does it stop ? Thanks.
