USCGC Juniper (WLB 201) deck department members prepare to move a buoy chain assembly while conducting aids to navigation operations in Kaneohe Bay, Hawaii, Dec. 10, 2025. A buoy chain assembly is one of the most critical components of an aids to navigation system, it secures the buoy to its anchor on the seafloor and allows the buoy to stay on station while moving safely with the tides, wind and swell.
