What does the flag hoist 'YG' signify?

The flag hoist 'YG' signifies that fishing activity is taking place in the area. This signal is used to alert other vessels to be cautious and maintain a safe distance to avoid interference with fishing operations. It serves an important role in maritime communication, ensuring that all vessels in proximity are aware of potential fishing activities, which can include the presence of nets or other fishing gear in the water. This is vital for the safety of both fishing vessels and other mariners navigating in the vicinity.

In maritime contexts, signals made by flag hoists are essential for conveying specific information quickly and effectively. By using standardized signals like 'YG', crews can facilitate safe interactions at sea and help prevent accidents related to fishing gear and operations. Awareness of such signals is crucial for maintaining navigation safety and ensuring that all maritime activities can coexist without incident.
