Which option is NOT a boundary for all vessels?

• A. Southwestern boundary - Perdido Key Bridge
• B. Southern boundary - Buoy #10 in the Pensacola Pass
• C. Northwestern boundary - Navy Blvd Bridge (Front Gate)
• D. Eastern boundary - Lexington Pier to CG Station on Santa Rosa Island

Answer: (D)

Understanding how vessel boundaries are defined helps you know what area is considered the active traffic zone. In this Pensacola area, the official safety and navigation boundaries are marked by fixed, recognizable features: the southwestern edge is set by Perdido Key Bridge, the southern edge by Buoy 10 in Pensacola Pass, and the northwestern edge by Navy Blvd Bridge (Front Gate). These lines create the defined area where normal vessel traffic is managed and monitored.

The line described as the eastern boundary from Lexington Pier to the Coast Guard Station on Santa Rosa Island is not used as a universal boundary for all vessels. That stretch does not serve as a blanket boundary for every vessel in the same way the other three do; navigation in that area can involve channels, shore access, or security considerations that do not apply in the same way as the established boundaries. Because of that difference, it’s the line that isn’t a boundary for all vessels, which is why it’s the correct choice.
