Chapter 6: Navigation & Communication Equipment
Thoroughly read and understand the navigation and communication manuals before using these systems for the first
time and observe the following:
Compass
Depth Finder
NOTICE
Compass accuracy can be affected by many factors. Have a qualified technician calibrate your
compass. Make sure the technician gives you a deviation card which shows the corrections to
apply in navigational calculations. Keep a copy of the deviation card at each helm.
• DO NOT use the depth finder as a navigational aid to prevent collision, grounding, boat
damage or personal injury.
• When the boat is moving, submerged objects will not be seen until they are already under
the boat.
• Bottom depths may change too quickly to allow time for the boat to react.
• If you suspect shallow water or submerged objects, run the boat at very slow speeds.
