What are ATONs in marine navigation?

• A. Buoys used as regulatory and channel markers
• B. Anchors used to moor ships
• C. Lighthouses only
• D. Weather buoys

Answer: (D)

ATONs are aids to navigation that help mariners determine safe course and position. Weather buoys fit into this network because they are fixed navigational aids that provide real-time weather, wind, and sea-state information for the area. This data supports route planning, speed decisions, and hazard awareness, making them part of the aids to navigation system. In contrast, anchors are equipment used to hold a vessel in place and do not aid navigation, while other common ATONs like regulatory markers, channel markers, and lighthouses mark safe waters or hazards.
