Buoys, Channel markers, and Beacons. Sound familiar? If they do, you are a seasoned boater. If you’re new to the boating world, red channel markers and green buoys can seem confusing to begin with.
These are the types of navigation aids, somewhat similar to road signs, used to determine the safe route on the water and follow the rules. In this blog, we’ll discuss channel markers, buoys, and what the colors red and green signify on the open water. It’s a big step in navigating safely through the open waters. Let’s get started –
Difference Between Channel Markers and Buoys
Talking about the different aids to navigate the water, there are –
- Floating Buoys – Anchored to the bottom – deep waters
- Fixed Markers – On poles and pilings – in areas where the water is shallow enough to drive a piling
You should treat fixed markers and buoys exactly the same.
Note: Check for the lighted markers and buoys. They will blink at a specific frequency. As these frequencies are marked on charts, you can look at them when you find a red colored marker blinking every three seconds. That way, you can track the nearest red marker that blinks at the same frequency.
Understanding Red and Green Colored Channel Markers
With distinct features, water markers are easily recognizable. Red and Green markers are the most easily identified markers. Also referred to as lateral markers, these define the boundaries of the preferred channel. In other words, these markers showcase the safe passage for vessels.
Apart from separating the channel, these markers are also used in directing traffic on water. Red and green colors signify different information depending on numbers, shapes, and other cues.
1. Red Marker
These are starboard-hand markers.
Use
A starboard hand marker is used as a reference when navigating upstream.
Position
It’s kept on the starboard or right side of the vessel.
Numbers
The numbers are always even; they go higher as you go further upstream.
Indicator
Triangle shape on a red marker (only used for day markers).
2. Green markers
Also referred to as port hand markers.
Use
These are used as guides when going downstream.
Position
Kept on the starboard or right side when going downstream.
Numbers
Odd numbers that go higher as you go further upstream.
Indicator
Square shape (only for day markers)
3. Red and Green Marker
Buoy with red and green bands.
Use
Bifurcation markers are used to diverge the water channels.
Preferred Channels
The bifurcation markers help you when the waterways divide. While all these markers serve the same purpose, their color patterns may differ.
- It’ll either be red or green on top of the bifurcation marker.
- Whatever color is visible on top determines the channel. For example, if there is red on top, follow the channel marked by red, with others becoming secondary.
Follow the Right Path
- Pay close attention to the markers positioned closest to the point where waterways divide.
- You’ll see one red and one green marker on either side of the bifurcation.
- Consider these markers as your guide to find the route.
- The color on the top of the marker reveals the route.
- Compare it with adjacent red and green markers to be clear about which path to follow.
Overall, these markers help you set sail more confidently while following the rules.
Confused about whether to move to open water or come back to the harbor? Understand different characteristics of the channel markers to sail safely.
| Characteristics | Red | Green | Things to Consider |
| Color | Red buoy on right: Returning from the bigger water body to the smaller one. | Green marker on right: Leaving the intercoastal waterway for open water | Keep in mind “Red, right, return” to understand the preferred channel. |
| Shape | Nun Buoy – Cone-shaped Triangle sign, no body: Boards or day beacons Cone top, cylindrical body: Channel buoys | Can Buoy – Cylindrical Shaped Square, no body: Day beacons or boards Flat top, cylindrical body: Channel buoys | Shapes aid in recognizing markers during the day. |
| Numbers | Even | Odd | Used to indicate distance from open water; increases when close to a harbor, decreases when close to open water. |
| Navigation | Starboard side when returning | Starboard side when leaving | Mix of color, shape, and number for safe navigation |
Overall,
- Leaving the dock –Green marker buoys – Odd numbers –Starboard side
- Coming back – Red marker buoys – Even numbers – Starboard side
Now that you have a solid understanding of green and red markers, let’s cover other types of markers and buoys.
Other Markers and Buoys
| Marker type | Position | Purpose |
| Day markers | Directly attached to water (red triangles and green cans) | Maximize visibility during the day |
| Special marks | Stand out yellow marks with a cross on top | Indicate the geography of the region (e.g. designated sports area, submarine cables) |
| Obstruction Marker | Black and white vertical strips | Indicate the barrier between the marker and the shore. |
| Danger marks | Red and black horizontal stripes | Indicate potential dangers on either side |
| Emergency Wreck Marking Buoys | Blue with yellow vertical strips | Indicate hazards |
| Fairway Buoys | White and red stripes | Indicate safe water areas |
| Non-lateral markers | White with orange stripes and black letters | Providing relevant information, danger warnings, or marking exact areas. |
| Mooring Buoys | White marks with blue stripes | Used for anchoring. Need permission to use them. |
| Control Buoys | White with an orange circle | Indicate speed limits, anchoring limitations, and no-wake zones |
| Cardinal Buoys | Yellow and black colored marks | Indicate the safest side to pass a hazard |
Overall, remember and understand these water channel markers and navigation aids to avoid any accident. These are an important part of boating and should never be taken for granted. The above-mentioned information can help you get started on understanding such an essential tool for hitting the open water safely.
Conclusion
If it’s your first time taking your boat out on the water, it’s normal to get confused. Take your time understanding these navigation aids. Every boater should know how to comply with the safe boating rules and regulations. In the United States, getting a boating license is important to head out legally on the water. It proves that you know how to drive a vessel safely while following all the laws.
