3. Maritime Zones within the Strait
13 The relevant maritime zones claimed by the strait States include a 12 nautical mile territorial sea, a 24 nautical mile
, and a 200 nautical mile EEZ, though Spain’s claim only extends to the Atlantic Ocean. In the case of Gibraltar, the United Kingdom only claims a 3 nautical mile territorial sea. The consequence of this is that on the western approach to the Strait ships pass through the EEZs of either Spain or Morocco, through which they enjoy the freedom of navigation, until such time as they enter either State’s territorial sea at which point the transit passage regime commences.
A right of transit passage is then enjoyed as a ship passes through the Strait, including through the territorial sea generated offshore to Gibraltar. Once a ship exits the Strait and passes into the Mediterranean Sea proper, the vessel will in most instances enter EEZ or high seas areas within which the freedom of navigation can be exercised.
