(i) Are of a large enough scale and have enough detail to make safe navigation of the area possible; and
(ii) Are currently corrected.
(2) For the area to be transited, a currently corrected copy of, or applicable currently corrected extract from, each of the following publications:
(i) U.S. Coast Pilot.

(b) As an alternative to the requirements for paragraph (a) of this section, a marine chart or publication, or applicable extract, published by a foreign government may be substituted for a U.S. chart and publication required by this section. The chart must be of large enough scale and have enough detail to make safe navigation of the area possible, and must be currently corrected. The publication, or applicable extract, must singly or in combination contain similar information to the U.S. Government publication to make safe navigation of the area possible. The publication, or applicable extract must be currently corrected, with the exceptions of tide and tidal current tables, which must be the current editions.
(c) As used in this section, “currently corrected” means corrected with changes contained in all Notices to Mariners published by the National Geospatial-Intelligence Agency, or an equivalent foreign government publication, reasonably available to the vessel, and that is applicable to the vessel's transit.
