Schematic map of maritime zones.
A nation's internal waters include waters on the landward side of the baseline of a nation's territorial waters, except in archipelagic states. It includes waterways such as rivers and canals, and sometimes the water within small bays. According to the United Nations Convention on the Law of the Sea, the coastal nation is free to set laws, regulate any use, and use any resource. Foreign vessels have no right of passage within internal waters, and this lack of right to innocent passage is the key difference between internal waters and territorial waters.
