I think the problem might be the unnecessarily mathematical description up to an additional 24 N nautical miles beyond the territorial sea where the territorial sea is N nautical miles wide N 12 If you were just skimming over the article it would be easy to misread that the 24 N as 24N i e 24 nautical miles Unless anyone objects I ll change this to a more plain English description such as A Contiguous Zone extends from the limit of the territorial sea up to a distance of 24 nautical miles from the baseline possibly also adding In cases where the country in question has claimed less than 12 nm for its territorial waters its contiguous zone may therefore be more than 12 nm wide Unless it has already been added and I have just missed it it needs to be mentioned that when territorial contiguous zones belonging to different countries intersect then the median line is taken as the boundary
