Article 15 Modification of power to give directions
Section 52 of the Act of 1847 shall not be construed so as to require the harbour master to give particular directions in the case of every vessel in respect of which it is desired to exercise any of the powers of that section; but in pursuance of that section for all or any of the purposes thereof, the harbour master may give general directions applicable to all vessels or to particular classes of vessels.
Section 53 of the Act of 1847 shall not be construed so as to require the harbour master to serve a notice in writing of his direction upon the master of a vessel, and such directions may be given orally or otherwise communicated to the master on any occasion when it is not reasonably practicable for a written notice to be served on the master.
