AN AID TO NAVIGATION IS..........ANY

EXTERNAL OBJECT THAT HELPS MARINER TO:

- WARN OF DANGERS OR OBSTRUCTIONS

- SAFE COURSE

- DETERMINE POSITION

LANDMARKS ARE NOT AIDS TO NAVIGATION

- BUT CAN BE USEFUL IF ON CHART FOR AREA

AIDSTO NAVIGATION

MAJOR TYPES OF AIDS

BUOYS-- FLOATING AIDS OTHER THAN LIGHTSHIPS

DAY BEACONS -- UNLIGHTED FIXED STRUCTURES IN OR NEAR THE WATER

LIGHTED, ACTIVE VISUAL SIGNALS

FOG SIGNALS-- FLOATING OR FIXED AIDS THAT SOUND

BELL, WHISTLE, GONG, OR HORN

RANGES -- FIXED PAIRS OF MARKERS THAT SHOW
