Non-lateral markers that feature crossed diamonds communicate a crucial warning to boaters about dangerous areas. This specific symbol signals that the waters are hazardous and should be avoided by all vessels. The crossed diamond is universally recognized in navigation to indicate obstacles or areas where navigation poses a risk, such as shallow waters, rocks, or areas with significant underwater hazards.

Understanding this marker is essential for ensuring safe boating practices. In contrast, markers indicating areas that are safe or clear for navigation would utilize different symbols, such as a circle or a simple diamond without crossing lines. Additionally, markers restricted to certain vessels would typically feature distinct symbols denoting specific regulations or limitations, rather than a crossed diamond. This clear distinction helps boaters make informed decisions while navigating their surroundings safely.
