A boat horn is a signaling device used on vessels to communicate with other boats and alert them of the ship's presence, particularly in foggy or low visibility conditions. It typically emits a loud, distinctive sound to ensure it can be heard over water and other ambient noises. Boat horns can vary in size and type, ranging from simple air horns to more complex electronic systems, and are essential for maritime safety and navigation.
