I have been trying with no luck to contact ferry/boat companies to see if there is any boat or ferry type transportation from Sorrento to Positano (or elsewhere on the Amalfi coast) in the early part of June. No one has responded to my emails. I know the ferries to Capri are operating but I have already been there and want to visit somewhere along the Amalfi coast by ferry, if possible. Does anyone know when the ferry companies start their summer operations? Should I try calling someone and what would be the best company to try and call?
