What does a white buoy with an orange diamond indicate?

A white buoy with an orange diamond is used to indicate a restricted area for navigation. This marking alerts boaters to areas where there may be hazards or where access is limited for safety reasons. Such restrictions can be in place due to various factors, including underwater obstructions, proximity to construction zones, or other navigational hazards that could pose risks to vessels.

Understanding these buoy markings is crucial for maintaining safety on the water, as they help inform you of areas that should be avoided or entered with caution, ensuring compliance with local navigation rules while protecting both the vessel and the environment. In contrast to the other options, which denote different uses such as swimming areas, safe channels, or fishing zones, the orange diamond specifically communicates restrictions that must be respected by all boaters.
