This is a compulsory fee of $40 per day. Although, the maximum charge is $400 for the charter, regardless of the duration. There is a deductible per incident dependent on the size of your vessel: $1500 for yachts 31ft–39ft, $2500 for yachts 40ft–46ft, and $3500 for yachts 47ft or larger. Pre-authorization with a Visa or MasterCard, prior to starting your charter, guarantees this insurance. Only if the boat or dinghy is damaged will your card be charged.
