The liveaboard business is a service industry, and although the general public is seldom aware of it, gratuities are a major part of a crewmember’s salary. Few other recreational activities rely so heavily upon the professionals in charge for your enjoyment and safety. A gratuity of 10-15% is customary, but many leave more when they feel the service was outstanding. If you are disappointed with the service, you should inform the captain of your feelings right away so he may rectify the situation. Gratuity can be paid in CUC, EURO or USD. However, if paying in USD, a 13% tax is imposed. It is best to convert to Euro or CUC.
