CABLES
The symbols for submarine and overhead cables do not differentiate between cables
conducting electric power, often at high voltages, and other types of utility cables. 
Mariners are advised to exercise caution when passing under all overhead cables and to
avoid anchoring or conducting seabed operations in the vicinity of submarine cables.
The clearance of an overhead cable may differ from its charted value due to changes in
atmospheric conditions, water levels and other factors. For additional information,
consult Notice No.16 in the Notices to Mariners, Annual Edition and the appropriate
volume of CHS Sailing Directions.

RADAR REFLECTORS

reflectors have not been charted.
