AIDS TO NAVIGATION
For complete details of aids to navigation, the larger-scale charts
and List of Lights, Buoys and Fog Signals must be consulted.


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 cables 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 on 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 and other factors.
For additional information, consult Notice to Mariners No.  16 of each year
and the appropriate volume of CHS Sailing Directions.


SMALL-CRAFT
The Georgian Bay small-craft charts must be used in order to navigate the
small craft route and adjacent waters.  These provide the details of Aids to
Navigation marking the route and other important information.
