If you charter one of the bigger yachts (longer than 50 feet), you will probably get at least two crew members with her. Luxury yachts are chartered only with full crew. Still, why wouldn't you want to have a few people who will take care of absolutely everything on board, while everything that you do is relax and have fun?
On these yachts, crew quarters are separate from the guest area, so you have your privacy.
Crew consists of captain, sailor, hostess and chef, and sometimes there is also a guard.
Each of them has their duties, and they are all professionals on which you can rely to keep things in order and under control.
Captain is in charge of navigating the yacht and setting the itinerary (in agreement with you); sailor is servicing boat, keeping her in good condition, helps the captain, assist with docking, and takes care of other minor maintenance; hostess makes sure that interior of the boat is clean and tidy; and the chef is in charge of preparing meals and supplying the boat with food and beverages. More detailed descriptions of the jobs of all crew member read in The Crew section.
If you have an entire crew on your disposal you don't have to worry about cooking, shopping, cleaning, managing the boat, navigation... All you need to do is to relax, enjoy the comfort of the luxury yacht and scenic beauty around you.
