Coastal Navigation - Markings For coastal channels in USA the rule is: –Red – Right – South Red Landward / Green Seaward Atlantic Intracoastal Water way (AICW), Gulf Intracoastal Water Way (GICW), Okeechobee Waterway –ICWs Part of Returning River The primary marking (R/G) is for the River Superimposed may be sub-marking for ICW

R RR Red – Right – Returning >> 2

Marker on port side underway. Look closely for yellow triangle under bird’s nest Which way traveling on ICW, N or S? Traveling North on the ICW

Marker on port side underway. Which way traveling on ICW, N or S? Traveling South on the ICW

Buoy on port side underway. Which way traveling on ICW, N or S, upstream or downstream? Traveling downstream toward the Atlantic Ocean (south on the ICW)

ICW Channel Only Southbound ICW – Landward –Red Triangle –Yellow Triangle – ICW Indicator –Always On Right (Landward) ICW – Seaward –Green Square –Yellow Square – ICW Indicator –Always On Left (Seaward)

Downstream on River Southbound on ICW ICW – Right Side –Green Square – River Marking Returning –Yellow Triangle – ICW Indicator –On Right; Landward Side ICW – Left Side –Red Triangle – River Marking –Yellow Square – ICW Indicator –On Left; Seaward Side

Upstream on River Northbound on ICW ICW – Right Side, Seaward –Red Triangle – River Marking Returning –Yellow Square – ICW Indicator ICW – Left Side, Landward –Green Square – River Marking –Yellow Triangle – ICW Indicator

Example of dual purpose channel Snows Cut and Cape Fear River Heading South –On the Cape Fear the markers switch from ICW to River Markers ICW – Red/Triangle on Westward Side or Right River – Red/Square on Eastward side or Left –From water the visual is very confusing Markers are every where Seas are often high and its recommend to have a good GPS course through here

Summary Presented were only a few of the complicated parts to North Carolina’s Aids to Navigation Always study your chart before your journey Understand which Aids of Navigation should be observed and why Read Chart and mark off aids as you go of the trip and highlight areas of concern *** Be vigilant of ICW markings especially when leaving from or returning to port via a river
