It includes a foreword by the Hydrographer of the Navy, Rear-Admiral George Stephen Ritchie (1914-2012), who served most of his Naval career in the Surveying Service providing the raw data for the Hydrographic Office. The introduction clearly states that with the publication of this volume the previous edition and its supplements are cancelled, since the most up-to-date information has been compiled in the new edition and the weekly "Notices to Mariners" that appear after the publication of the 11th edition. The 11th edition of 1967 and its 1977 supplement were made redundant with the publication of the 12th edition in 1980. Each subsequent edition of the pilot supersedes the last, which have appeared infrequently depending on newly available information since the mid-19th century until the present day. - Binding slightly rubbed and faded, first two pages are printed on red/pink paper, edges of the volume are very slightly soiled.
