INTRODUCTION AND EXPLANATION OF TABLES.
This list describes all aids to navigation maintained by or under the authority of
the United States Department of Commerce on the coast of Porto Rico and adjacent
islands, Navassa Island, and Guantanamo Bay, Cuba.
Arrangement of List.-The aids are arranged as nearly as practicable in the order
in which they are used, commencing at San Juan Harbor and following clockwise
around the island to the point of beginning. The aids of the several harbors, etc., are
arranged in regular order, beginning at each entrance under separate references. In
some instances aids have been repreated for convenience in navigation.
Names of aids are printed in this List as follows:
PRIMARY SEACOAST LIGHTS.
Secondary Lights.
RIVER, HARBOR, AND OTHER LIGHTS.
LIGHTED BUOYS.
Unlighted fixed aids.
Unlighted Buoys.
Other publications.-The Department of Commerce publishes annually a Light
List for the Atlantic and Gulf coasts, including Porto Rico, which includes all lighted
aids and fog signals. The department also publishes annually for each lighthouse
district a Buoy List similar to this.
As far as the location of buoys and other aids to navigation is concerned, the charts
are a preferable source of information.
Buoy and light lists of the Department of Commerce are for sale by the Superintendent of Documents, Washington, D. C., and by the sales agencies.
Charts, Coast Pilots, and Tide Tables of the waters covered by this List are published by the Department of Commerce and are for sale by the United States Coast
and Geodetic Survey; they are also for sale by the sales agencies.
Correction of Light and Buoy Lists.-The Lists are corrected to the date of
publication as printed on the title-page. The mariner is cautioned that the latest
List must be used. It is not practicable for the department to correct individual
copies, but "Notice to Mariners" is published weekly, announcing all changes in aids
to navigation. The navigator should keep his Lists, as well as his charts, corrected
from these notices, and should consult all notices issued after the date of publication
of the List.
The weekly Notice to Mariners will be mailed regularly, free of charge, to any
mariner who will apply to the Deparment of Commerce, through the Division of
Publications, Washington, D. C.
Defects in aids to navigation.-Mariners are requested to report direct to the
Superintendent of Lighthouses, San Juan, P. R., by radio or other prompt means,
defects in aids to navigation.
Recommendations as to aids to navigation, or their improvement, or reports of aids
no longer needed, should be mailed to the above address, or to the Department of
Commerce, through the Commissioner of Lighthouses, at Washington, D. C.
Information respecting dangers, changes in shoals and channels, and other facts of
interest affecting charts and coast pilots should be sent to the Department of Commerce through the Coast and Geodetic Survey, Washington, D. C.

Laws for the protection of aids to navigation.-Whoever shows any false light
with intent to bring any vessel into danger or shipwreck shall be imprisoned not less
than 10 years and may be imprisoned for life.           A
It is unlawful for any person to interfere with any aid to navigation or to anchor
any vessel in navigable waters of the United States so as to obstruct range lights, and
any person so doing may be fined $500 for each offense, and each day during which
such violation continues shall be considered a new offense.
It is unlawful for any person, corporation, or municipality to establish or maintain
in the navigable waters of the United States any aid to navigation similar to those
maintained by the Department of Commerce without first obtaining permission from
the Department of Commerce through the Commissioner of Lighthouses; and any
person so doing may be fined $100 for each offense. (Regulations governing the establishment of private aids to navigation are given in Department of Commerce Circular
No. 213, third edition, Sept. 24, 1918).
Porto Rico has passed laws providing penalties to be paid by persons interfering
in any manner with the aids to navigation -established and maintained by the United
States.
Collisions of vessels with lightships, buoys, and other aids to navigation.-The licensed officer in command of a vessel colliding with any aid to navigation must report the collision promptly to the Department of Commerce through the
nearest board of local inspectors of steamboats.
Bearings are in degrees true, reading clockwise from 0~ at N. t( 360~; bearings relating to visibility of lights are given as observed from a vessel.
Distances are in nautical miles, unless otherwise stated.
Heights are referred to mean high water.
Depths are referred to mean low water.
Unwatched lights. —"U" after the name of a light indicates that the light is
unwatched; gas buoys are also unwatched. These unwatched lights may become
irregular or extinguished, although a high degree of reliability has been attained with
such apparatus.
Reliance must not be placed on lighted buoys maintaining their exact positions;
in cases of uncertainty it is safer to navigate by bearings or angles to fixed objects on
shore, and by soundings.
Character of lights.-To avoid confusion between lights, they are given distinct
characteristics. These are indicated by abbreviations, as follows:


(2) Lights which do
change color (show(1) Lights which do not change                                             change color (show
color(1) Lights wcdonotchang  Characteristic phases.           ing alternately white
and red in various
combinations).
F.- Fixed.................... A continuous steady light....................... Alt.= Alternating.
Fl.= Flashing............... (a) Showing a single flash at regular intervals... Alt. FI.= Alternating
(b) A steady light with total eclipses.       flashing.
F. Fl.- Fixed and flashing.... A fixed light varied at regular intervals by one  Alt. F. Fl.= Alternator more flashes, usually of greater brilliancy.  ing fixed and flashA flash is preceded and followed by a diminu-  ing.
tion of light or an eclipse.
Gp. Fl.- Group flashing....... Showing at regular intervals groups of flashes..  Alt. Gp. Fl.= Alternating group flashing.
Occ.- Occulting.............. A steady light suddenly and totally eclipsed at Alt. Occ.=Alternating
regular intervals.                           occulting.
Op. Occ.- Group occulting.... A steady light suddenly and totally eclipsed by
a group of two or more eclipses. 
W.-White; R.- Red; G.-Green.




5


A flash is usually shorter than the duration of an eclipse.
An occultation is shorter than or equal to the duration of light.
Lights are characterized as flashing or occulting according to the relative durations of light and darkness and without reference to the type of illuminating appa-:ratus employed or relative brilliancy.
In approaching a light of varying intensity, such as fixed varied by flashes, or
alternating white and red, due allowance must be made for the inferior brightness
of the less powerful part of the light. The first-named light may, on account of distance or haze, show flashes only, and the true characteristic will not develop until
the observer comes within the range of the fixed light; similarly the second named
may show as occulting white until the observer comes within range of the red
light. Also where there are two fixed lights, one white and one red, the latter may
be obscured and the station may appear to show only a fixed white light.
At short distances and in clear weather flashing lights may show a faint continuous
light.
Period of a flashing or occulting light is the time required to go through the full
set of changes, and is given in the column "Name, etc.-Character and period of
light," and the details are stated in the column "Remarks-Fog signal."
The durations of light and darkness are computed, and may vary slightly.
Visibility of lights.-The distances at which lights may be seen in clear weather
are computed in nautical miles for a height of the observer's eye of 15 feet above
sea level. These distances may at times be increased by abnormal atmospheric
refraction, and of course may be greatly lessened by unfavorable weather conditions,
due to fog, rain, haze, or smoke. Weak lights and colored lights are easily obscured
by such conditions.
Under certain atmospheric conditions, especially with the more powerful lights,
the glare of the light may be visible beyond the computed geographic range. When
approaching a light, it evidently may be seen earlier from aloft.
Candlepowers of lights are stated approximately in English candles. When the
power of a light varies, as in the case of a white light with a red sector or a fixed light
varied by flashes, the candlepower of both white and red, or fixed light and flash, is
given.
Light sectors.-In some conditions of the atmosphere white lights may have a
reddish hue; the mariner therefore should not trust solely to color where there are
sectors, but should verify the position by taking a bearing of the light. On either
side of the line of demarcation between white and red there is always a small sector
of uncertain color. The edges of a sector of visibility can not be cut off sharply.
When a light is cut off by adjoining land, and the arc of visibility is given, the bearing on which the light disappears may vary with the distance of the vessel from which
observed. When the light is cut off by a sloping point of land or hill, the light may
be seen over a wider arc by a ship far off than by one close to.
Whistling and bell buoys are operated by the action of the sea; therefore they
sound irregularly, and in calm weather are less effective or may not be heard.
Caution regarding buoys.-Buoys are liable to be carried away, shifted, capsized, sunk, etc., lighted buoys may be extinguished, or whistling or bell buoys may
not sound, as the result of storm or other natural causes, or collision, or other accidents.
Buoy colors, numbers, and shapes.-The following orderis observed in coloring
and numbering buoys:
In approaching the channel, etc., from seaward, RED BUOYS, with EVEN NUMBERS,
are on the STARBOARD side, and BLACK BUOYS, with ODD NUMBERS, on the PORT side.
Buoys with RED and BLACK HORIZONTAL STRIPES are on OBSTRUCTIONS, with channelways on either side of them, and may be left on either hand in passing in.




6


BuoYs with WHITE and BLACK PERPENDICULAR STRIPES are in MIDCHANNEL, and
must be passed close-to.
Nun buoys, properly colored and numbered, are usually placed on the starboard
side, and can buoys on the port side, of channels.
Day beacons are constructed and distinguished with special reference to each
locality, and particularly in regard to the background upon which they are projected. Beacons on the sides of channels, when practicable, are colored to conform
to the coloring of buoys, subject to the above conditions as to background.
Lighthouse tenders when working on buoys in channels or other frequented
waters may display a red flag (international signal-code letter "B ") and a black ball at
the fore, as a warning to other vessels to slow down in passing. Passing vessels will
facilitate the work of the Department of Commerce by a proper observance of the
signals.
