Yes, more boat trips below and boat hire with or without skipper. We've done several boat trips including one to Capri and another boat trip around the island. Some people have their favourite boat companies but I think they are all pretty similar. There is also a ferry from Sorrento to Capri and you can hire boat trips when you get there.
TUI also do boat trips and there are many others.
The Golden Tours trip is very good.
