A national registration for a ship which does not correspond to its actual ownership or control. Owners may choose this for tax reasons, to avoid stringent controls on safety and manning prevailing in their own countries, or to allow the use of foreign crew at lower wages than those payable to their own nationals. The practice is bitterly criticised both by national seamen's unions and by owners who do not avail themselves of the opportunities for cost savings offered by the use of flags of convenience.
