Aids to Navigation

Aids to Navigation are devices or systems that are external to a vessel. Aids to Navigation can include buoys, day beacons, range markers, and lighthouses. They are to boaters what road signs are to drivers.


Aids to Navigation are provided to :

  • Help the operator determine position and course;
  • Warn of dangers or obstructions, or
  • Indicate the location of the safest or preferred route.
REMEMBER: It is important to be thoroughly familiar with the aids to navigation in your region.
