The meaning of APA (Advance Provisioning Allowance) is an advance payment required to pay your operating expenses on a luxury yacht, this amount is mostly 30% of the total charter fee amount.
Why do you need to pay APA? Because your charter fee does not include extra expenses aside from the rental cost of the yacht. Before your arrival and during your stay, all operating expenses (diesel and fuel, harbor fees, local taxes, customs fees, food, beverages, etc.) will be completed by the captain. Before disembarkation, an additional payment can be required from the captain in case the advance payment has been completely used or if there is spending less you will have the difference refunded to you.
