A dual-purpose buoy is typically indicated by its design and markings, which serve two functions, such as navigation and mooring. These buoys often feature distinct colors, shapes, or lights that signal their multifaceted roles, such as providing information to mariners while also serving as a mooring point for vessels. Additionally, the presence of specific symbols or patterns may denote their dual use.

A buoy that is white with vertical stripes is typically a "safe water buoy," also known as a "fairway buoy." This type of buoy marks the limits of safe water and indicates that navigators can pass on either side. The vertical stripes often help in identifying the buoy's purpose, making it easier for mariners to navigate safely in open waters.
Danger
A white buoy with a blue horizontal band indicates a mooring buoy. In many states, this is the only type of buoy to which a vessel may be tied legally.
The yellow buoy is a warning that indicates underwater pipes or shoals. Boats need to stay clear of yellow buoys.
A mooring buoy is typically designated by a specific color and markings, often identified by a large, white, or brightly colored buoy with a clear, visible number or letter that indicates its purpose. These buoys are used to provide a secure point for vessels to tie up without anchoring, helping to prevent damage to the seabed. The designation can vary by location, so it’s important to refer to local navigational charts for specific information.
A buoy with both red and green bands typically marks a navigational channel or indicates a junction where vessels can either proceed straight or choose a side. The red band usually indicates the port side (left when entering from the sea), while the green band indicates the starboard side (right when entering from the sea). This type of buoy helps mariners navigate safely through waterways. Always refer to local navigation charts for specific meanings, as buoy color codes can vary by region.
A white buoy with an orange marking most likely indicates that you should proceed through the area with caution. The buoy often marks rapids, rocks, or sandbars.
A mooring buoy is typically a white buoy with a blue horizontal band or strip around it. This coloration helps boaters identify the buoy's purpose, indicating that it is designated for mooring vessels. The blue stripe serves as a visual cue to ensure safe and proper usage of the buoy for anchoring.
A buoy marked with the number four and a flashing red light typically indicates a specific navigational point in maritime settings. It often serves as a warning or marker for hazards or navigational channels, particularly in areas requiring caution. The flashing red light enhances visibility, especially during low-light conditions, helping vessels identify the buoy's location and purpose.
A buoy that indicates safe water on all sides is colored white with horizontal blue stripes. This type of buoy is known as a safe water mark and signals that there are no obstructions nearby, allowing for safe passage. The design typically helps navigators identify safe areas in navigable waters.
A white buoy with an orange crossed diamond symbol indicates an obstruction in the water, such as a rock or a wreck. This buoy signals boaters to proceed with caution and to avoid the area marked by the buoy to ensure safety. It is important for navigators to be aware of such markers to prevent accidents.
