WARNING ON USE OF FLOATING AIDS TO NAVIGATION TO FIX A NAVIGATIONAL POSITION

The aids to navigation depicted on charts comprise a system consisting of fixed and floating aids with

varying degrees of reliability. Therefore, prudent mariners will not rely solely on any single aid to navigation,

particularly a floating aid.

The buoy symbol is used to indicate the approximate position of the buoy body and the sinker which

secures the buoy to the seabed. The approximate position is used because of practical limitations in

positioning and maintaining buoys and their sinkers in precise geographical locations. These limitations

include, but are not limited to, inherent imprecisions in position fixing methods, prevailing atmospheric and sea

conditions, the slope of and the material making up the seabed, the fact that buoys are moored to sinkers by

varying lengths of chain, and the fact that buoy and/or sinker positions are not under continuous surveillance

but are normally checked only during periodic maintenance visits which often occur more than a year apart.

The position of the buoy body can be expected to shift inside and outside the charting symbol due to the forces

of nature. The mariner is also cautioned that buoys are liable to be carried away, shifted, capsized, sunk, etc.

Lighted buoys may be extinguished or sound signals may not function as the result of ice or other natural

causes, collisions, or other accidents.

For the foregoing reasons, a prudent mariner must not rely completely upon the position or operation of

floating aids to navigation, but will also utilize bearings from fixed objects and aids to navigation on shore.

Further, a vessel attempting to pass close aboard always risks collision with a yawing buoy or with the

obstruction the buoy marks.

INTRODUCTION

The National Geospatial-Intelligence Agency publishes

a List of Lights, Radio Aids and Fog Signals in seven vol-

umes divided geographically as shown on the index chart-

let on the inside front cover of this book. Major fixed and

outermost floating aids to navigation, such as sea buoys,

safety fairway buoys, traffic separation buoys, etc., are

listed. Other floating aids are not generally listed. Storm

signals, signal stations, radio direction finders, radiobea-

cons, RACONs and RAMARKs located at or near lights

are found in this List. Radiobeacons are listed in a separate

section in the back of this publication.

The date to which this publication has been corrected

can be found in the Preface. In the interval between new

editions, corrective information affecting this publication

will be published in Section II of Notice to Mariners, and

must be applied to keep this publication current. All of

these corrections should be applied in the appropriate

places and their insertion noted in the “Record of Correc-

tions.”

Mariners and other users are requested to forward new

or corrective information useful in the correction of this

publication to:
