Article 70 Nautical publications
This Rule applies to every vessel of 12 metres in length and over to which these Rules apply which proceeds more than 5 nautical miles from the coast.
The Secretary of State hereby specifies the charts described in paragraph (3) below and the directions and information mentioned in paragraph (4) below, as the charts, directions and information which appear to him necessary or expedient for the safe operation of vessels to which this Rule applies.
The said charts are those—
which are of such a scale and which contain sufficient detail as clearly to show—
all navigational marks which may be used by a vessel when navigating the waters which are comprised in the chart,
all known hazards affecting those waters, and
any information concerning traffic separation schemes, two-way routes, recommended tracks, inshore traffic zones and deep water routes applicable to those waters and areas therein which are to be avoided;
which are either published by the Hydrographer of the Navy or, if not so published, are of a similar scale to those so published and contain equivalent detail; and
which, in all cases, are of the latest available edition and—
in the case of charts published by the Hydrographer of the Navy, have been corrected from all relevant Notices to Mariners and Radio Navigational Warnings, and
in the case of charts not so published, have been otherwise adequately corrected.
In paragraph (b) above the reference to the Hydrographer of the Navy includes a reference to any authority in any country other than the United Kingdom duly exercising functions similar to those of the Hydrographer.
For the purposes of paragraph (c)(ii) above, a chart shall be treated as adequately corrected if, in relation to a voyage made by the vessel which is carrying the chart in accordance with paragraph (5)(a) below, all relevant corrections to that chart applicable up to a time 9 months before the beginning of that voyage have been made.
The said directions and information are such as is contained in the publications mentioned in column 1 of Schedule 25 to these Rules, being publications which, in all cases, are of the latest available edition and which incorporate the latest relevant supplements and, in the case of any such publication which is published otherwise than by the publisher specified opposite thereto in column 2 of the said Schedule, is of equivalent standard and content.
Every vessel to which this Rule applies which goes to sea or attempts to go to sea shall carry at least—
one copy of a chart which complies with the requirements specified in paragraph (3) above, being a chart which is appropriate for each part of the intended voyage; and
one copy of each of the publications mentioned in Schedule 25 to these Rules, with English language text, as is appropriate for that voyage.
