What is the minimum visibility distance for registration numbers on a vessel?

The minimum visibility distance for registration numbers on a vessel is 30 meters. This requirement is in place to ensure that the numbers can be easily read by other vessels and authorities from a safe distance, which is crucial for identification and safety purposes. The visibility of registration numbers is essential for preventing illegal activities and ensuring that all vessels can be accounted for in case of an incident. A distance of 30 meters strikes a balance between practicality and safety, allowing enough space for identification without being excessively far away. This regulation helps maintain order on the waterways and ensures better compliance with maritime laws.
