Paragraph 11 Reserved and recreational areas
The Secretary of State or the Queen’s Harbour Master may, where he considers it necessary to reserve any area for mining, gunnery or dredging operations or experiments, or other naval purposes, or to ensure the safe navigation of other vessels both naval and civilian, issue a general or local notice, which shall continue in force until 31 December of the year in which it was issued, unless revoked earlier, prohibiting any person from—
causing or permitting a vessel to enter into or remain in that area, unless compelled to do so by stress of weather or to avoid accident;
entering into or remaining in that area, or from causing or permitting any vessel, animal or thing to enter into or remain in that area, except with the permission of the Queen’s Harbour Master or the officer in charge of such operations, experiments or purposes; or
taking part in any recreational activities specified in the notice in such parts of that area as may be so specified, save for the purposes of avoiding danger or accident.
