Coastal Navigation - Markings

Learn about the navigation rules and markings for coastal channels in the USA, including the Atlantic Intracoastal Waterway (AICW) and Gulf Intracoastal Waterway (GICW). Understand the use of Red-Right-Returning (R/R/G) markers and dual-purpose channel indicators like Snows Cut and Cape Fear River. Study your charts, follow the rules, and stay vigilant while navigating these waterways.

  1. 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 Coastal Navigation - Markings

  2. Red – Right – Returning R R R >> 2

  3. 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

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

  5. 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)

  6. ICW Channel OnlySouthbound • ICW – Landward • Red Triangle • Yellow Triangle – ICW Indicator • Always On Right (Landward) • ICW – Seaward • Green Square • Yellow Square – ICW Indicator • Always On Left (Seaward)

  7. Downstream on RiverSouthbound 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

  8. 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

  9. Example of dual purpose channelSnows 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

  10. North Snows Cut and Cape Fear River

  11. 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
