What are the extra costs I need to be aware of, apart from the charter price?

Food, drinks, port or marina fees are extra costs regardless of yacht type you’ve chartered. On motor yachts you should also take care of fuel costs since gulets and small cruise ships very often have fuel for up to 4 hours of navigation daily included in charter price. Any other costs, such as water toys usage, National parks tickets, special transfer costs or yacht relocation fees are optional costs and are completely up to you.

Roughly, for yachts up to 60 thousand EUR per week you could calculate extra costs as 30% of charter price, while percentage would be lower for higher priced yachts.
