Frequently Asked Questions

Is this boat insured, and who pays for damage?

Yes — every boat on charter.boats is insured by its operator; we require it. The policy covers the vessel for fire, collision and third-party liability. You're only responsible for damage it doesn't cover, and that's capped at the security deposit.

Do I need a sailing licence in Italy?

The skipper needs a valid sailing licence and VHF certificate, ideally issued by their country of residence (an ICC is widely accepted).
