What is indicated by a crossed diamond buoy?

A crossed diamond buoy indicates areas that are off-limits to all boats. This type of buoy serves as a warning to mariners that they should not enter the designated area, which may be closed due to safety reasons, environmental protection, or other regulations. The crossed diamond symbol is a universal sign that signifies a prohibition, making it crucial for boaters to recognize this buoy to ensure compliance with navigation laws and maintain safety on the water.

In contrast, other buoy types represent different meanings. For example, controlled speed zones might be indicated by buoys with specific markings related to speed limits, and open fishing areas would generally not have any prohibitory symbols but rather would signal that fishing is allowed. Dangerous waters would likely be marked by a buoy displaying a specific hazard warning, not necessarily a crossed diamond. Understanding these signals ensures that boaters can navigate safely and responsibly in various water bodies.
