What kind of areas does a crossed diamond (non-lateral marker) denote?

A crossed diamond symbol, as a non-lateral marker, indicates closed or exclusion areas in navigable waters. This means that these areas are restricted and should not be entered or used by boat operators. The purpose of such markings is to ensure safety and prevent boats from entering hazardous zones, such as construction areas, overspill areas, or regions designated for wildlife protection.

It is crucial for boaters to recognize and comply with these markers to maintain safety on the water and adhere to regulations that protect both people and the environment. Understanding the implications of a crossed diamond helps ensure that boating activities are conducted safely and responsibly.
