Barbados–Saint Lucia

On 6 July 2017, the maritime boundary between the Caribbean islands of Barbados and Saint Lucia was established. This new boundary entered into force over two years later, on 1 September 2019. The maritime boundary, which extends for 59 nautical miles, begins north of both islands at the tripoint with the French island territory of Martinique and follows an equidistant line comprised of 21 turning points. The boundary terminates in the south at a tripoint with Saint Vincent and the Grenadines.

Saint Lucia is a small island of volcanic origin that lies approximately 78 nautical miles west-northwest of Barbados, which is the easternmost island in the West Indies’ Lesser Antilles.
