All updates to lighted aids, including their operational status, will be published in thissection. All directions and bearings are measured clockwise from true the North 000o to
360o. Bearing on lights is based on the observer from seaward toward the light. The
visibility assigned to the lights never exceeds the calculated distance at which they can beseen from a height of 4.57 meters above the level of the water at high tide.
Changes in aids to navigation, their maintenance, and correction of deficiencies inoperation are under the operation of the Philippine Coast Guard. Report of defects andrecommendations concerning aids to navigation should be forwarded to the Commandantof the Philippine Coast Guard.

Such information is published for the sake of the safety of navigation on Philippine waters
and does not imply recognition of the legal validity of the information issued by theabovementioned sources.
3. While every effort is made to ensure the accuracy of NAMRIA nautical charts andpublications, users should bear in mind that it may not be complete or up-to-date,especially in areas where there are extensive developments. Mariners are advised toexercise prudence and to also refer to all navigational equipment aboard the ship and use

Buoys and beacons are sometimes lost or destroyed, especially after typhoons.
Temporary deficiencies in the standard aids to navigation published in this office may havebeen corrected before subsequent notice is issued.
5. Positions obtained from satellite navigation systems, such as GPS, are normally referredto the WGS-84 Datum. Such position may only be plotted on NAMRIA nautical charts thatare also referred to the WGS-84 Datum. Mariners should take note that due to the age
and quality of some of the information, such satellite-derived positions may be moreaccurate than charted details.

INSTRUCTIONS
1.

Mariners are requested to notify the Hydrography
Branch of the National Mapping and Resource
Information Authority (NAMRIA) when new orsuspected dangers to navigation are discovered,changes observed in aids to navigation, or corrections
to publications that are seen to be necessary.
Mariners can also report any ENC display issues
experienced.

2.

This form and its instructions have been designed tohelp both the sender and the recipient. It should be
used, or followed, closely, whenever appropriate.
Copies of this form may be obtained gratis from the
NAMRIA Hydrography Branch at 421 Barraca St., San
Nicolas, Manila, or by requesting thru email at
maritime.affairs@namria.gov.ph.

3.

Position: When a position is defined by sextant
angles or bearings (true or magnetic being specified)more than two should be used in order to provide acheck. Distances observed by radar should be quoted.
However, when there is a series of fixes along a ship’s
course, only the method of fixing and the objects
used need to be indicated. Latitude and longitude
should only be used specifically to position the details
when they have been fixed by astronomical
observations or GPS and a full description of themethod, equipment and datum used should be given.

4.

Paper Charts: A cutting from the largest scale paper
chart is the best medium for forwarding details, thealterations and additions being shown thereon in red.
When requested, a new copy will be sent in
replacement of a chart that has been used to forward
information, or when extensive observations have
involved defacement of the observer’s chart. If it ispreferred to show the amendments on a tracing of
the largest scale chart (rather than the chart itself)
these should be in red as above, but adequate detailfrom the chart must be traced in black ink to enable
the amendments to be fitted correctly.

bathymetric data may still be of use, and sentin accordingly. Where full data sets areincluded, a note as to the data owner and their
willingness for the data to be incorporated into
charts and ENCs included.
5.

a.
b.
c.

Soundings: When soundings are obtained, it isimportant to ensure that full details of the method ofcollection are included in this report. This include nut
no limited to:
a.
b.

c.

d.

Make, model, and type of echo sounder used.
Whether the echo sounder is set to register
depths below the surface or below the keel; inthe latter case the vessel's draught should begiven.
Time, date and time zone should be given inorder that corrections for the height of the tide
may be made where necessary, or a statement
made as to what corrections for tide havealready been made.
Where larger amounts of bathymetric data
have been gathered, only those areas where asignificant difference to the current chart or
ENC should be specifically mentioned on the
H102. The full data set may also be sent in,with an additional note added to this effect. If
no significant differences are noted, thethe trace being weaker than normal for thedepth recorded;
the trace passing through the transmission
line;
the feathery nature of the trace.

As a check that apparently shoal soundings are notdue to echoes received beyond the set's nominal
range, soundings should be continued until
reasonable agreement with charted soundings isreached. However, soundings received after one ormore rotations of the stylus can still be useful andshould be submitted if they show significant
differences from charted depths.
6.

Reports which cannot be confirmed or arelacking in certain details should not be
withheld. Shortcomings should be stressed and any
firm expectation of being able to check theinformation on a succeeding voyage should be
mentioned.

7.

Changes to Port Information should be forwarded
using Hydrographic Note for Port Information. Where
there is insufficient space on the forms additional
sheets should be used.

8.

Reports using this form and relevant data should besent either through mail at NAMRIA Hydrography
Branch, 421 Barraca St., San Nicolas, Manila or
through email at maritime.affairs@namria.gov.ph.

Electronic Navigational Charts (ENCs): A screen
grab of the largest scale usage band ENC with thealterations and additions being shown thereon in red.
5.

For Echo Sounders that use electronic ‘range
gating’, care should be taken that the correct range
scale and appropriate gate width are in use. Olderelectro-mechanical echo sounders frequently record
signals from echoes received back after one or morerotations of the stylus have been completed. Thus,
with a set whose maximum range is 500m, an echo
recorded at 50m may be from depths of 50m, 550m
or even 1050m. Soundings recorded beyond the set's
nominal range can usually be recognized by thefollowing:

An acknowledgement or receipt will be sent and theinformation then used to the best advantage which may
mean immediate action or inclusion in a revision in due
course; for these purposes, the UKHO may makereproductions of any material supplied. When a Notice toMariners is issued, the sender's ship or name is quoted as
authority unless (as sometimes happens) the information is
also received from other authorities or the sender states thatthey do not want to be named by using the appropriate tickbox on the form. An explanation of the use made ofcontributions from all parts of the world would be too great atask and a further communication should only be expected
when the information is of outstanding value or has

unusual features.
