NOTES:

NOTE A
Navigation regulations are published in Chapter 2, U.S. Coast Pilot 10.  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, 14th Coast Guard District in Honolulu, Hawaii or at the Office of the District Engineer, Corps of Engineers in Honolulu, Hawaii.
Refer to Code of Federal Regulations section numbers. 


AUTHORITIES
Hydrography and topography by the National Ocean Service, Coast Survey, with additional data from the U.S. Coast Guard, Geological Survey, U.S. Navy, and National Geospatial-Intelligence Agency.
 

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


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.


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).


SUPPLEMENTAL INFORMATION
Consult U.S. Coast Pilot 10 for important supplemental information.


CAUTION - TEMPORARY CHANGES
Temporary changes or defects in aids to navigation are not indicated on this chart. See Local Notice to Mariners.


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.


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.


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


NOAA WEATHER RADIO BROADCASTS
The NOAA Weather Radio stations listed below provide continuous weather broadcasts. The reception range is typically 37 to 74 km / 20 to 40 nautical miles from the antenna site, but can be as much as 186 km / 100 nautical miles for stations at high elevations.

Kokee, HI			KBA-99		162.40 MHz
Mt Kaala, HI			KBA-99		162.55 MHz
Hawaii Kai, HI			KBA-99		162.40 MHz
Mt Haleakala, HI		KBA-99		162.40 MHz
Kulani Cone, HI			KBA-99		162.55 MHz
South Point, HI			KBA-99		162.55 MHz


SUBMARINE PIPELINES AND CABLES
Additional uncharted submarine pipelines and submarine cables may exist within the area. 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 exists, and when anchoring, dragging, or trawling. Covered wells may be marked by lighted or unlighted buoys.


SUBMARINE FISH AGGREGATING DEVICES
Submarine Fish Aggregating Devices (FADs) are contained within this area at depths of 12.1 to 30.5 meters / 40 to 100 feet below the surface. Mariners are advised to use caution when entering and transiting. 


SUBMERGED SUBMARINE OPERATING AREAS
Submarines may be submerged in these areas, vessels should proceed with caution.  During torpedo practice firing, all vessels are cautioned to keep well clear of Naval Target Vessels flying a large red flag at the highest masthead.


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 .
