The Territorial Sea (Limits) Order 1987
This Order establishes the seaward limit of the territorial sea adjacent to the United Kingdom in the narrow part of the Straits of Dover and in the vicinity of the Isle of Man. The limit in the Straits of Dover is constituted by straight lines joining the points indicated in the Schedule and follows the line already agreed for the continental shelf by the Agreement of 24th June 1982 with the Government of France (T.S. No. 20 (1983) Cmnd. 8859) where that line is within twelve miles of the baselines of the United Kingdom. The limit in the vicinity of the Isle of Man is the median line.
