What is a benefit of the IALA buoyage system?

The benefit of the IALA buoyage system that stands out is the standardization of navigation aids globally. This system provides a consistent framework for buoyage that is recognized and utilized by mariners in many parts of the world, promoting safer navigation. By establishing uniform standards for light characteristics, colors, shapes, and other navigational aids, the IALA buoyage system helps to minimize confusion among international mariners. When navigational aids are standardized, it becomes easier for vessels from different regions to interpret the same signals and markings, which reduces the risk of accidents and enhances overall maritime safety.

While other options touch on aspects of maritime operations, they do not accurately convey the primary purpose and essential benefit of the IALA system. For example, while standardization may indirectly affect the number of vessels at sea or reduce reliance on pilot services, it primarily serves to improve understanding and navigation among vessels sharing international waters.
