Multi-day trips require an APA (Advanced Provisioning Allowance) of 30-40% of the base charter fee. This includes fuel, food, beverages, customs fees, dockage, etc., plus any expenses consumed by your group while on board. The APA is sent to the yacht before the charter in order to provision the yacht according to your preferences. The captain will provide a detailed accounting of the usage of the APA funds. Any leftover funds will be returned to you at the end of the charter. It is customary to pay a 15-20% gratuity to the crew at your discretion.
