I don't know any one who rents boats with out a captain,for just that reason. The waters locally are hazardous to people who don't know them. It might even be against the law. Not trying to be mean but the area is practically void of markers ,signs and buoys that a boating community might normally have. Unwise ,not just for your own safety and the cost of damages to the boat but damage to the reef.
