APA stands for Advance Provisioning Allowance. It is not a fee and not the charter price: it is your own money, paid in advance, that the captain spends on your trip as it happens — fuel for the boat and tender, food and drinks, marina and port fees, water and shore power, and similar running costs [1].
It exists so you are not settling a bill at every fuel dock and quay; the captain pays as you go and you get one account at the end [2].
The operator sets it as a percentage of the charter price, usually somewhere between 20% and 40% [2]. Sailing yachts sit at the lower end because they burn little fuel; motor yachts sit higher because fuel is most of what the APA pays for [3].
On charter.boats you see the operator's own rate and the amount for your dates before you book — for example "APA (30% of list price)". The percentage is taken on the operator's list price, before any discount, so on a discounted week the APA is a bigger share of what you actually pay. Where an operator states it on the price before VAT and we can't be sure how tax applies, the amount is marked "est.".
- The captain holds the APA and pays running costs from it, keeping receipts [4]
- Whatever is not spent is refunded to you [1]
- If costs exceed the APA — expensive marinas, lots of motoring, premium provisioning — you're asked to top it up during the charter [1]
The APA does not cover the charter itself, VAT on it, or crew tips [1].
On each boat the APA is shown under Deposits, beside the security deposit, and in the price box on its own line under the Total — marked either "charged now, included in Due now" or "paid at pickup, not included in price", depending on the operator.
It is not the security deposit: the deposit is a guarantee against damage that you get back if nothing is damaged, while the APA is spent on your trip.
Send the crew a preference sheet before you go — what you eat and drink, how much you want to motor, whether you prefer anchorages or marinas — and ask for the APA statement at the end [5].
