The price of chartering a yacht depends on various parameters such as region, season, model, size, etc. For example, a brand new four cabin 8 passenger yacht in Croatia for a week in May could cost 1700 euros per week if booked well in advance. On the other hand, a similar yacht in Italy might cost 2500-3000 euros per week or more. Remember the rule of thumb: the earlier you start looking, the more options you will have and the cheaper they will be.
