Many people are chartering to expand their cruising experience. For the newcomer to this vacation alternative, there are some nagging thoughts which can become quite serious worries as the departure date draws near. Generally speaking, the degree of formality on board is dictated by the size of the yacht. On a very large vessel there will be little communication with the crew except through the captain and stewards. The captain will dine with the guests upon their invitation.
Most charters are of much smaller yachts.
Due to the intimacy of the surroundings, a more casual attitude works better. You can set the tone of the charter from the moment you meet the captain. If you introduce yourself by your first name, that's how you will be introduced. The yacht is required to be dean and in proper condition for putting to sea. If it is not, you can require the necessary work be carried out.
