gas buoy
Quick Summary
A gas buoy is a metal buoy filled with compressed illuminating gas. It is topped with a lantern that burns gas day and night, serving as a floating light to guide ships in coastal waters and near harbors. These buoys, along with lightships, are mobile and can be repositioned as needed, for instance, to mark shifting sandbanks.12
Buoys in general are used to mark safe channels, dangers, and traffic lanes. They are typically made of steel or fiberglass and can range in size. Modern buoys may also include radar reflectors and fog signals, with power often supplied by solar panels or batteries.2
