Rockall

Rockall is small, rocky island in the North Atlantic. It is an area of high dispute, being claimed by four different countries (United Kingdom, Ireland, Denmark and Iceland). On itself the island does not have much importance, but the seas around it are considered very valuable. As such, it is also an important question whether Rockall is considered inhabitable or not - if it is, whoever is its owner can claim 200 nautical miles of [exclusive economic zone]?, if not, the claim can go no further than Rockall's [territorial waters]?.
