What is the minimal height requirement for registration numbers on a vessel?

The minimal height requirement for registration numbers on a vessel is 3 inches. This standard is established to ensure that the registration numbers are clearly visible and easily readable from a distance. This visibility is crucial for identification purposes, especially on busy waterways where many boats may be present. Properly displaying the registration numbers not only helps authorities identify vessels for safety and regulatory reasons but also aids in preventing theft or illegal activity. Other heights mentioned are not compliant with the regulations, as numbers that are too small may not be seen or recognized quickly, compromising their effectiveness in identification.
