What does a non-lateral diamond marker indicate?

A non-lateral diamond marker serves a specific purpose in maritime navigation, indicating warnings of hazards and obstructions. These markers are typically used to draw attention to potential dangers that may not be obvious but require caution when navigating through those waters.

Non-lateral markers are important for safe navigation as they effectively alert boaters to specific risks like rocks, shallow areas, or other underwater hazards that could pose a threat to vessels. By providing this crucial information, the markers help ensure that boaters can avoid accidents and operate their vessels safely.

In contrast, other types of markers serve different functions. For instance, navigation assistance markers help guide vessels through channels, controlled area markers indicate areas with restrictions on speed or access, and distance markers typically show how far a vessel is from a specific point in relation to the navigational route.
