A Rock feature is above water at high tide, uninhabitable. It is entitled to which zone?

The situation hinges on how features above water at high tide are treated in maritime zones. An island can generate a territorial sea (and, from there, EEZ rights) only if it can sustain human habitation or economic life of its own. A rock that is above water at high tide but uninhabitable does not meet that criterion, so it does not create its own territorial sea or EEZ. To keep ships safe around such hazards, authorities establish a safety zone around the feature. That makes a safety zone the appropriate entitlement for navigation safety around an uninhabitable rock above water. The other zones are tied to sovereign coastline, habitation, or resource rights and don’t apply to this feature.
