The Advanced Provisioning Allowance acts as a bank account and is designed to cover expenses that cannot be fixed in advance, such as food and drink, fuel, and berthing fees. The APA is typically around 25 to 35%. of the yacht charter fee and is paid before the charter commences. The captain is responsible for logging all APA expenses and you can view the expenses at any time during your boat charter. Any funds left in the APA at the end of your charter holiday are immediately refunded to you.
