NOAA CUSTOM CHART

NOTES GEOSPATIAL DATABASE

VERSION 3.0B - 20 FEBRUARY 2025

The records of the NOAA Custom

Chart Notes Geospatial Database are

current as of February 20, 2025.

Subsequent additions and refinements

are to be expected. Please refer to

all

available

navigational

publications for complete information

about the charted area.

CAUTION

AUTOMATED CHART GENERATION

This NOAA Custom Chart has been

automatically

rendered

from

NOAA

Electronic Navigational Chart (NOAA

ENC®) data. Mariners using this NOAA

Custom Chart are advised that this is

a static reproduction of the NOAA

ENC®. This NOAA Custom Chart has not

been individually quality checked or

adjusted

for

optimal

use

for

navigation. The portrayal may be at a

different scale from that of the

original NOAA ENC®. Mariners are

advised to use caution when using

this NOAA Custom Chart for navigation

and are encouraged to use the latest

NOAA ENC® to access the most up-to-

date information. Mariners must also

comply with all applicable regulatory

requirements.

CAUTION

CHART UPDATES

This NOAA Custom Chart contains up-

to-date information only as of the

time of creation, and will become

outdated. Mariners are advised to

visit

https://

distribution.charts.noaa.gov/

navigation-updates/

to

check

for

critical and routine updates, and to

render a new NOAA Custom Chart when

the ENC data used to make the chart

is updated. Notices to Mariners are

not issued for corrections to this

NOAA Custom Chart.

HEIGHTS

Heights of fixed aids to navigation

and vertical clearances of overhead

obstructions will be shown in feet if

the units are set to feet or fathoms.

If units are set to meters, heights

will

be

shown

in

meters.

Land

elevation values are shown in meters

only.

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.

CAUTION

SUBMERGED CABLES AND PIPELINES

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

Temporary changes or defects in

aids to navigation are not indicated

on this chart. 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.

NOTE Z

NO-DISCHARGE ZONE, 40 CFR 140

Under the Clean Water Act, Section

312, all vessels operating within a

No-Discharge

Zone

(NDZ)

are

completely

prohibited

from

discharging any sewage, treated or

untreated,

into

the

waters.

All

vessels with an installed marine

sanitation device (MSD) that are

navigating,

moored,

anchored,

or

docked within a NDZ must have the MSD

disabled to prevent the overboard

discharge

of

sewage

(treated

or

untreated) or install a holding tank.

Regulations for the NDZ are contained

in the U.S. Coast Pilot. Additional

information

concerning

the

regulations and requirements may be

obtained

the

Environmental

Protection

Agency
