    Intracoastal Waterway buoys and navigational markers are like most other lateral marks in the U.S. the difference is that yellow triangles or yellow squares are added to the mark to indicate they are ICW markers. The rule is: When proceeding southbound on the Atlantic Intracoastal Waterway (Norfolk, VA to Cross Bank in the Florida Keys) or northbound / westbound on the Gulf Intracoastal Waterway (Ft. Meyers, FL to Brownsville, TX); markers with yellow triangles are kept to starboard and yellow squares are kept to port at all times.
