CHAPTER 6: On The Waterways
THE UNIFORM STATE WATERWAYS MARKING SYSTEM, CONTINUED
Other Non-Lateral Markers
Here are some other types of non-lateral markers.
Indicates an underwater obstruction. Do not pass between this marker and the shoreline.
SAFE WATER MARKER
Indicates a safe water area. Used to mark presence of land falls, channel entrances, or channel centers. It may be passed on either side.
A Diving Marker indicates the presence of divers in the area, which means you need to navigate with extra care.
There are two types of diving markers:
a red and white flag carried on top of a buoy indicates the area where diving is in progress;
a blue and white flag indicates a vessel engaged in diving activity.
In most states, you need to stay at least 100 feet from any dive flag, but check the regulations in the state in which you are boating for specific rules.
Remember, divers may stray from the boundaries of the marked areas, so always proceed with caution.
