What is the level of he gratuity ?

The tip is purely voluntary. If you decide that you want to tip the captain and the crew (if they have been professional, helpful, etc.) it is customary 5%-10% of the basic charter amount. The tip has to be given before your departure or to be discussing with the broker and written on the contract. If there are multiple crew members, we recommend you to give the tip to the captain and he will allocate it, equally divided, to the rest of the crew.
