NOTES:

NOTE A
Navigation regulations are published in Chapter 2, U.S. Coast Pilots 1 & 2. Additions or revisions to Chapter 2 are published in the Notice to Mariners. Information concerning the regulations may be obtained at the Office of the Commander, 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.

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


POLLUTION REPORTS
Report all spills of oil and hazardous substances 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).


CAUTION - USE OF RADIO SIGNALS (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.


SUPPLEMENTAL INFORMATION
Consult U.S. Coast Pilot 1 and 2 for important supplemental information.


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 endangered by ice, certain aids to navigation are replaced by other types or removed. For details see U.S. Coast Guard Light List.


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.


WATER LEVELS, CURRENTS, AND TIDES
Real-time water levels, tide predictions, and tidal current predictions are available on the internet from NOAA's Center for Operational Oceanographic Products and Services (CO-OPS) at https://tidesandcurrents.noaa.gov/water_level_info.html and https://tidesandcurrents.noaa.gov/currents_info.html.


ADDITIONAL INFORMATION

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


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.


ADMINISTRATION AREA
The entire extent of this ENC cell falls within the limits of an Administration Area. This area covers land, internal waters, and territorial sea. The territorial sea is a maritime zone over which the United States exercises sovereignty extending to the airspace as well as to its bed and subsoil. For more information, please refer to the Coast Pilot.


CABLE AND PIPELINE AREAS
The cable and pipeline areas falling within the areas of the larger scale charts are shown thereon and are not repeated.


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


CAUTION - NON-NAVIGATIONAL ZONES
Certain areas on this chart between the shoreline and the 2-meter curve are considered to be non-navigational. Of shallow depth, and away from port facilities, installations, channels, routes, tracks, and navigable waters, these areas may contain features with poor positional accuracy or of questionable existence. Some of these features may not be depicted, or depicted out of position. Mariners are advised to avoid these areas, or use extreme caution if transiting.


CAUTION - SMALL CRAFT
Small craft should stay clear of large commercial and government vessels even if small craft have the right-of-way. All craft should avoid areas where the skin divers flag, a red square with a diagonal white stripe, is displayed.


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 submarine 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 - 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. For more information visit https://navigation.usace.army.mil/Survey/Hydro/.


COLREGS 80.145
International Regulations for Preventing Collisions at Sea, 1972. The entire area of this chart falls seaward of the COLREGS Demarcation Line.


COLREGS, 80.145
International Regulations for Preventing Collisions at Sea, 1972. The entire area of this chart falls seaward of the COLREGS Demarcation Line.


CONTIGUOUS ZONE
The Contiguous Zone is a zone contiguous to the territorial sea, in which the United States may exercise the control necessary to prevent and punish infringement within its territory or territorial sea of its customs, fiscal, immigration, cultural heritage or sanitary laws and regulations. For more information, please refer to the Coast Pilot.


EXCLUSIVE ECONOMIC ZONE (EEZ)
The EEZ is a zone beyond and adjacent to the territorial sea within which the U.S. has certain sovereign rights and jurisdiction. Under some U.S. laws, the inner limit of the EEZ extends landward to the seaward limit of the states submerged lands. For more information, please refer to the Coast Pilot.

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.

CITY		STATION		FREQUENCY	BROADCAST TIMES
Hyannis, MA	KEC-73		162.550 MHz
Boston, MA	KHB-35		162.475 MHz
Providence, RI	WXJ-39		162.400 MHz	24 hours daily


OCEAN DUMPING SITES
Regulations for Ocean Dumping Sites are contained in 40 CFR, Parts 220-228. Additional information concerning the regulations and requirements for use of the sites may be obtained from the Environmental Protection Agency (EPA). See U.S. Coast Pilots appendix for addresses of EPA offices. Dumping subsequent to the survey dates may have reduced the depths shown.


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.


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.


COMMENTS REQUESTED
NOAA encourages users to submit inquiries, discrepancies, or comments about this chart via NOAA's ASSIST tool at https://www.nauticalcharts.noaa.gov/customer-service/assist/.


CAUTION - QUALITY OF BATHYMETRIC DATA
The areas represented by the object M_QUAL (Quality of data) are approximate due to generalizing for clarity. Caution is advised, particularly for nearshore navigation or voyage planning. M_QUAL represents areas of uniform quality of bathymetric data. The CATZOC (Category of zone of confidence in data) attribute of M_QUAL provides an assessment of the overall zone of confidence.
