The boundary is a simplified equidistant line that runs in a south–south-east direction until it terminates at the tripoint of Anguilla. It is far longer and more complicated than the Anguilla–U.S. Virgin Islands boundary: it is about 200 nautical miles (370 km; 230 mi) long and consists of 49 straight-line segments defined by 50 individual coordinate points. The full name of the treaty is Agreement between the Government of the United Kingdom of Great Britain and Northern Ireland and the Government of the United States of America on the Delimitation in the Caribbean of a Maritime Boundary between Puerto Rico/US Virgin Islands and the British Virgin Islands.
