Dart Harbour & Navigation Authority ( Dart Harbour ) is a Trust Port. The Trust Port was originally constituted by Act of Parliament in 1897 and amalgamated with the River Dart Navigation Commission to form the Dart Harbour and Navigation Authority on 1st August 1975. Trust ports are independent statutory bodies established under local Acts of Parliament. They are run by boards of trustees who reinvest all profits for the benefit of all port users and wider regional and local interests. In 2006 a review of the corporate identity has led to the Authority being known as Dart Harbour.
