Orange borders on a mark typically signify what?

Orange borders on a mark are used to signify regulatory or information marks. These marks provide important instructions or information to mariners, such as speed limits, no-wake zones, or other regulatory guidance that must be followed to ensure safety and compliance with local maritime laws.

The use of an orange border makes these marks visually distinct, allowing them to be easily recognized by boaters. Regulatory marks are crucial in guiding the behavior of vessels in certain areas for navigation and safety purposes.

In contrast, other types of marks have different color codes and purposes; for example, danger zones would typically be marked differently to indicate hazards, while construction areas might use specific signage or cones. Temporary aids to navigation are also marked in ways that differ from permanent regulatory marks, often indicating more transient conditions or information.
