Whenever any emergency arises which, in the opinion of the Admiralty renders it advisable that His Majesty's Coastguard shall be placed under the control of the Admiralty, the Admiralty may by order direct that the management and control of His Majesty's Coastguard shall be transferred to the Admiralty, and while any such order is in force, the powers and duties of the Board under this Act in relation to His Majesty's Coastguard shall be exercised and performed by the Admiralty, and the officers and men of His Majesty's Coastguard shall be subject to the Naval Discipline Act and be borne on the books of one of His Majesty's ships in commission, with such respective ranks and ratings and such pay and emoluments as may be determined by the Admiralty.

Any order made under this section shall be revoked as soon as the Admiralty is of opinion that the emergency has ended, but without prejudice to anything previously done thereunder.
