Buoys are essential for harbor safety and security, marking safe channels, hazards, and designated zones for vessels. They guide ships through navigation routes, helping to prevent collisions, grounding, and damage to infrastructure. Equipped with lights and signals, buoys are visible at night and in poor weather, offering crucial visual cues for mariners. They also support security by defining restricted areas, ensuring vessels keep a safe distance from sensitive locations. Some buoys are now equipped with sensors to monitor water conditions and report on security threats, enhancing situational awareness for harbor authorities.
