The key idea is how coastal features are categorized and what zones they can generate. An island is a landform that can sustain human habitation or economic life and, under international law, can generate a territorial sea and an exclusive economic zone. A rock that is above water at high tide but cannot sustain habitation or economic life does not get those zones. To protect navigation around such hazards, authorities typically establish a safety zone around the feature.

So, a rock above water at high tide that is uninhabitable does not have its own territorial sea or EEZ; the appropriate protection around it is a safety zone to prevent vessels from approaching too closely. If it were habitable, it would be treated as an island and would generate a territorial sea (and, if applicable, an EEZ).
