For private Turkish yacht charter, there really isn’t a set minimum age level for children to be a part of a gulet charter holiday. This is left up to the discretion of the parents or adults accompanying the children who will be on board.
It is however the responsibility of the guests to mind the children while they are on board or on shore during these Turkey gulet cruise vacations. Travelers who have brought children or infants with them on their holidays can do so freely.  It is advisable to inform your yacht charter agent the age of children 12 years and younger, particularly if there will be toddlers coming on board the gulet.  The gulets and the gulet cruise itself is prepared to ensure the safety of all guests aboard as well as the crew.
This includes the organization of the itinerary and anchorage points.  There are life jackets, lifesavers, fire extinguishers and similar items on board at all times; as well as a tender in the event of an emergency and guests or crew need to be taken to shore.
If you have decided to have a family vacation and looking to enjoy gulet holidays with children, there will be a great deal of options for children to enjoy themselves while on board and ashore. Water sports activities can be suitable for ages 10 and up. Again, engaging in such activities is left up to and the responsibility of the parents or adults who have come on board for the gulet holiday.
Types of water activities other than swimming and snorkeling could be water skiing, jet skiing (with adult), ringos, banana boats, and the like.  Other pastimes could include satellite TV, DVD player, music system, ipod dock, playstation and internet access – depending on the gulet rental.
