NOTES:
AIDS TO NAVIGATION
Consult U.S. Coast Guard Light List for 
supplemental information concerning aids to 
navigation.


AUTHORITIES
Hydrography and topography by the National 
Ocean Service, Coast Survey, with additional 
data from the corps of Engineers, Geological 
Survey, and U.S. Coast Guard.


CAUTION - DREDGED AREAS
Improved channels are 
subject to shoaling, particularly at the edges.


CAUTION - LIMITATIONS
Limitations on the use of radio signals as 
aids to marine navigation can be found in the 
U.S. Coast Guard Light Lists and National 
Geospatial-Intelligence Agency Publication 117.
Radio direction-finder bearings to commercial 
broadcasting stations are subject to error and 
should be used with caution.


CAUTION - SUBMARINE PIPELINES AND CABLES
Additional uncharted submarine pipelines and 
submarine cables may exist within the area of 
this chart. Not all submarine pipelines and sub-
marine cables are required to be buried, and 
those that were originally buried may have 
become exposed. Mariners should use extreme 
caution when operating vessels in depths of 
water comparable to their draft in areas where 
pipelines and cables may exist, and when 
anchoring, dragging, or trawling. 
Covered wells may be marked by lighted or 
unlighted buoys.


CAUTION - TEMPORARY CHANGES
Temporary changes or defects in aids to 
navigation are not indicated. See 
Local Notice to Mariners.
During some winter months or when endan-
gered by ice, certain aids to navigation are 
replaced by other types or removed. For details 
see U.S. Coast Guard Light List.


NOAA WEATHER RADIO BROADCASTS
The NOAA Weather Radio stations listed 
below provide continuous weather broadcasts. 
The reception range is typically 20 to 40 
nautical miles from the antenna site, but can be 
as much as 100 nautical miles for stations at 
high elevations.

Boston, MA        KHB-35     162.475 MHz
Hyannis, MA       KEC-73     162.55 MHz
Providence, RI    WXJ-39     162.40 MHz


NOTE A
Navigation regulations are published in Chapter 2, U.S. 
Coast Pilot 2. Additions or revisions to Chapter 2 are pub-
lished in the Notice to Mariners. Information concerning 
the regulations may be obtained at the Office of the Com-
mander, 1st Coast Guard District in Boston, MA or at the 
Office of the District Engineer, Corps of Engineers in 
Concord, MA.
Refer to charted regulation section numbers.


POLLUTION REPORTS
Report all spills of oil and hazardous sub-
stances to the National Response Center via 
1-800-424-8802 (toll free), or to the nearest U.S. 
Coast Guard facility if telephone communication 
is impossible (33 CFR 153).


RACING BUOYS
Racing buoys within the limits of this chart 
are not shown hereon. Information may be 
obtained from the U.S. Coast Guard District 
Offices as racing and other private buoys are 
not all listed in the U.S. Coast Guard Light List.


SUPPLEMENTAL INFORMATION
Consult U.S. Coast Pilot 2 for important 
supplemental information.


WARNING - PRUDENT MARINER
The prudent mariner will not rely solely on 
any single aid to navigation, particularly on 
floating aids. See U.S. Coast Guard Light List 
and U.S. Coast Pilot for details.


RADAR REFLECTORS
Radar reflectors have been placed on many 
floating aids to navigation. Individual radar 
reflector identification on these aids has been 
omitted from this chart.


TIDAL INFORMATION
For tidal information see the NOS Tide Table publication or go to http://co-ops.nos.noaa.gov.


ADDITIONAL INFORMATION
Additional information can be obtained at www.nauticalcharts.noaa.gov


USACE HYDROGRAPHIC SURVEYS
USACE conducts hydrographic surveys to monitor navigation conditions.
These surveys are not intended to detect underwater features. Uncharted
features hazardous to surface navigation are not expected but may exist
in federal channels.
