The Cayman Islands (Territorial Sea) Order 1989
This Order extends the boundaries of the Colony of the Cayman Islands so as to include, as territorial sea, the sea within twelve nautical miles of the baselines of the Cayman Islands, together with its seabed and subsoil, and makes other provisions in this connection. In particular, it defines the baseline from which the breadth of the territorial sea is measured as generally the low-water line, except where there are fringing reefs or bays.
