What color indicates that you are in the Intracoastal Waterway (ICW)?

In the context of the Intracoastal Waterway (ICW), yellow marks are used to indicate that you are navigating within this specific waterway system. These yellow markers serve as navigational aids, helping boaters identify the route and clarify their position within the ICW. The yellow color is specifically designated for these types of markings to differentiate them from the familiar red and green buoys that indicate safe passage in navigational channels outside of the ICW.

Understanding this distinction is crucial for safe navigation, as it informs mariners that they are in an area specifically designated for travel within the Intracoastal Waterway, thereby enhancing their situational awareness and navigation skills.
