If your plan is to charter a smaller yacht for you and your family and can handle the vessel yourself then you can enjoy the absolute privacy. However, if chartering for a larger group which will require a sizable yacht then it may not be practical to man the yacht yourself. You may end up spending most of your time wrangling with the yacht rather than enjoying your vacation.
Crewed yacht charters are a perfect way to enjoy the luxury and comfort of a large or super-yacht without having to worry about any of the details of your voyage. The crew of the yacht is well trained, professional, and courteous and will provide the level of service that is fit for royalty. You will hardly notice the presence of the crew, and will be able to enjoy your time with your family and friends.
