What is the legal requirement for displaying a vessel's registration number?

The legal requirement for displaying a vessel's registration number mandates that it must be clearly displayed on both sides of the bow. This specification ensures that the registration number is easily visible for identification purposes, which is crucial for law enforcement, regulatory compliance, and navigational safety. Displaying the number on both sides allows for visibility from different angles, facilitating effective monitoring and enforcement by Coast Guard and other law enforcement personnel.

The requirement reflects a broader emphasis on safety and accountability within recreational and commercial boating. If registration numbers were only displayed on the stern or only when docked, it could hinder the ability of authorities to identify vessels in motion or at various locations. This visibility is particularly important in areas heavily trafficked by boats and when vessels are traversing navigable waters.
