Where must every registered boat display its decal?

Every registered boat must display its decal on the stern. This placement is critical for visibility and compliance with regulations, allowing authorities to easily identify registered vessels. By placing the decal on the stern, it ensures that the registration details are visible from behind the boat, which is particularly important when the boat is in motion or docked.

While other areas of the boat, such as the bow or the starboard/port sides, might seem logical for display, they do not provide the same level of visibility and compliance as the stern. The stern is generally the standard location for registration decals as it aligns with regulatory requirements, ensuring that law enforcement and other officials can quickly access the necessary information about a vessel.
