Generally, the baseline is the low-water line round the coast, including the coast of all islands, but between Cape Wrath and the Mull of Kintyre it is a series of straight lines joining specified points to seaward of the islands off the coast. Where there are well-defined bays elsewhere, lines not more than 24 nautical miles in length are drawn across them.
Where is the baseline from which the breadth of the UK’s territorial sea is measured?
