Captain is the highest ranked officer on board. There are different categories of captains, as there are different categories of boats, but one thing is sure, captain is always right and he has the last saying in all ship matters. Captain's job is to drive the yacht, as well as taking care of necessary paperwork and making sure that everything goes well. Of course, you can arrange your itinerary with him, but in case of bad weather or any other problem while on sea, you must always obey the captain and do as he tells you. Every crew member has his assignments, but the captain never does any labor work. He navigates the yacht and gives his suggestions for you routes. It is mandatory that a captain possess an adequate license, depending on the type and the size of the vessel and sailing area, and also officer's certificate that he achieved through his professional education.
