What is the minimum height for registration numbers on a planing capable power boat?

The minimum height for registration numbers on a planing-capable power boat is 150 mm. This requirement is in place to ensure that the registration numbers are easily readable from a distance, which aids in identification during inspections and enhances safety on the water. Clear visibility of registration numbers is crucial for law enforcement and marine safety authorities to monitor compliance with boating regulations.

The size is specifically determined based on the type of vessel and its operational characteristics. For planing vessels, which can reach higher speeds, clear and larger identification numbers help ensure that they can be identified swiftly and accurately. This standard contributes to safe and responsible boating practices, fostering accountability and law adherence among boat operators.

Other heights listed as options may not provide the same clarity and visibility required in active waterways, especially in situations where quick identification is needed. Therefore, the established minimum height of 150 mm serves a vital purpose in marine regulation and navigation safety.
