If you think you crew did a great job we recommend tipping them at the end of the charter. They work hard to make your trip unforgettable and they will really appreciate it. There is no standard amount and recommendations vary depending on the size of your group and the yacht. As a guide, the average tip is usually around €100 per passenger for a skippered charter and €150 per passenger for a skipper/hostess charter. This is just a suggestion and in no way required.
On charters without a hostess, it is also a nice gesture of courtesy to offer the skipper snacks and some lunch during the week. This is a minimal cost to you and they are often sailing all day won’t have time to prepare lunch on their own.
