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.
