What does an orange diamond non-lateral marker indicate?

An orange diamond non-lateral marker indicates a hazard. These markers are used to alert boaters to potential dangers in the water, such as shoals, rocks, or other obstacles that may pose a risk to navigation. The orange diamond shape specifically signifies that caution is required, as these hazards are usually unmarked or poorly marked by other navigational aids.

When navigating through areas with these markers, boaters should be particularly vigilant and consider altering their course or speed to avoid accidents or grounding. Understanding the function of these markers is crucial for safe boating practices, as encountering unmarked hazards can lead to dangerous situations or damage to vessels. The other options—sailing routes, fishing areas, and resting areas—are indicated by different types of markers that serve specific functions in guiding boaters.
