Courses.— Courses are true, and are expressed in the same
manner as bearings. The directives “steer” and “make good” a
course mean, without exception, to proceed from a point of
origin along a track having the identical meridianal angle as the
designated course. Vessels following the directives must allow
for every influence tending to cause deviation from such track,
and navigate so that the designated course is continuously
being made good.

Explanatory Remarks
Sailing Directions are published by the National Geospatial-
Intelligence Agency (NGA), under the authority of Department
of Defense Directive 5105.40, dated 12 December 1988, and
pursuant to the authority contained in U. S. Code Title 10,
Sections 2791 and 2792 and Title 44, Section 1336. Sailing
Directions, covering the harbors, coasts, and waters of the
world, provide information that cannot be shown graphically
on nautical charts and is not readily available elsewhere.
Currents.— Current directions are the true directions toward
which currents set.
0.0
Dangers.— As a rule outer dangers are fully described, but
inner dangers which are well-charted are, for the most part,
omitted. Numerous offshore dangers, grouped together, are
mentioned only in general terms. Dangers adjacent to a coastal
passage or fairway are described.
0.0
Sailing Directions (Enroute) include detailed coastal and
port approach information which supplements the largest scale
chart produced by the National Geospatial-Intelligence
Agency. This publication is divided into geographic areas
called “Sectors.”
0.0
Distances.— Distances are expressed in nautical miles of 1
minute of latitude. Distances of less than 1 mile are expressed
in meters, or tenths of miles.
0.0
Bearings.— Bearings are true, and are expressed in degrees
from 000° (north) to 360°, measured clockwise. General
bearings are expressed by initial letters of points of the com-
pass (e.g. N, NNE, NE, etc.). Adjective and adverb endings
have been discarded. Wherever precise bearings are intended
degrees are used.
0.0
Geographic Names.— Geographic names are generally
those used by the nation having sovereignty. Names in paren-
theses following another name are alternate names that may
appear on some charts. In general, alternate names are quoted
only in the principal description of the place. Diacritical marks,
such as accents, cedillas, and circumflexes, which are related to
specific letters in certain foreign languages, are not used in the
interest of typographical simplicity. Geographic names or their
spellings do not necessarily reflect recognition of the political
status of an area by the United States Government.
0.0
Charts.— Reference to charts made throughout this publi-
cation refer to both the paper chart and the Digital Nautical
Chart (DNC).
0.0
Coastal Features.— It is assumed that the majority of ships
have radar. Available coastal descriptions and views, useful for
radar and visual piloting are included in geographic sequence
in each Sector.
0.0
Heights.— Heights are referred to the plane of reference
used for that purpose on the charts and are expressed in meters.
0.0
Corrective Information.— Users should refer corrections,
additions, and comments to NGA’s Maritime Operations Desk,
as follows:
0.0
Index-Gazetteer.— Navigational features and place-names
are listed alphabetically in the back of the book. The approxi-
mate position, along with the Sector and paragraph numbers
(e.g. 1.1 ), facilitate location in the text.
