Yes, because if you charter a boat, your or your customers determine who comes on board with them or not. Every boat has a maximum number of passengers, to which you have to pay attention – but except your customers (and, if necessary, the skipper, if you rent a boat with skipper), only your own guests will be aboard. This is why exclusive charter is also a bit more expensive than public boat tours, but in exchange, you’ll have the boat entirely for your customers and you or they can decide, where to go and when and where to anchor.
