When must a boat operator display their vessel registration number?

A boat operator must display their vessel registration number on both sides of the bow when operating on public waters to ensure compliance with federal and state regulations. This requirement promotes safety and accountability on the water, allowing law enforcement officials and other boaters to easily identify vessels. Proper display of the registration number also helps in promoting responsible boating practices and can assist in the recovery of stolen boats. It's important for operators to adhere to this guideline in all areas where they are required to be registered, as it is standard practice designed to enhance overall boating safety and organization on public waterways. Other options do not align with the comprehensive requirement for visibility at all times while on public waters.
