CABLES
For the mariners' safety, all submarine and overhead cables are assumed to 
conduct electric power at high voltages and contact with or proximity to these 
poses an extreme danger.  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.  However, if anchors become hooked onto a 
cable care must be taken not to sever the cable.  Cables installed since the 
date of publication of this ENC may not be charted.  Sufficient clearance must 
be allowed under all overhead cables.  Actual clearances may differ from charted 
values due to changes in atmospheric conditions, ice buildup and/or water 
levels.  For additional information, consult Notice to Mariners No. 16 of 
each year and the appropriate volume of CHS Sailing Directions.
